Hi all, I have 2 hard drives which have the same problem: they are recognize in the bios as capacity 0. I've tried alot of recovery software, to connect the hard drives to other computer, to try and fix the mbr but nothing with success :( after a deep research on the internet I got a conclusion which the problem related to the lba of the disk. How do I fix that problem and put out my data? How to update/renew the hard drive's lba? Thank you very much! It would definitely help, if you were kind enough as to tell us what harddrives you have that show this very problem. ;) My guess would be that those are Seagate Barracuda 7200.11 drives. But let us know some details. I have 3 hard drives with the same problem. 2 of them are seagate's Barracuda 7200.11 750 GB and 500 GB and the theard one is Western Digital's 320 GB. I've tried to use MHDD in order to erase the mbr (CLRMBR) and I get the system error: "This drive does not support LBA mode or not detected" I've tried also NHPA which recover the factory size and it doesn't work (probably bacuse the LBA problem). How do I recover the LBA of those hard drives? Is there any tool or software for that? Thank You Very Much!!

The fastest way to ensure loss of important data. Seriously, if data is important consult a professional who can give you an exact failure report, and a quote for the recovery of your data. As all 3 drives are failed, presumably from the same system, you may have an electrical or mechanical failure but this is just a guess, an accurate indication of the problem is impossible without proper analysis.

The 3 hard drives each one from a different computer and a different house, so I don't have any electrical problem with my computer. The biggest question is how do I fix the "LBA mode"/LBA problem of the disk?! It's all the time shows me that the hard drive is a 0 capacity and it drives me nuts :| Thank you very much for any help! :) MadOCer New subject: Re: Capacity 0 in the bios If you really insist on a DIY solution then you should also be able to find the solution (or let's say a detailed description) for 2 of your 3 problem cases online. ;) That doesn't mean that it will work per se, without a doubt.

When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area). This process is also known as remapping, and "reallocated" sectors are called remaps. This is why, on modern hard disks, "bad blocks" cannot be found while testing the surface – all bad blocks are hidden in reallocated sectors. However, as the number of reallocated sectors increases, the read/write speed tends to decrease. The raw value normally represents a count of the number of bad sectors that have been found and remapped. Thus, the higher the attribute value, the more sectors the drive has had to reallocate.

I have been looking around the web for a forum that might be of help to me. I decided to stop here first only because I have used Hard Disk Recovery Lab products in the past, so I am presuming the forum would contain knowledgeable people. I am in a bit of a problem with a HDD. It is completely my fault. This is not a question of drive failure, only human failure. I have a Seagate 1TB FreeAgent external Drive which I intended to use as backup. I only purchased it 3 weeks ago, so it should be pretty healthy. Anyway, because I had so many other random 3.5" drives lying around, near failing, I ended up putting everything of value on this Seagate, and then, of course realized I had defeated the purposes of a "back-up" drive, and now needed to backup my drive that was to be my backup drive. Of course, I never got around to doing this for the ensuing 2-3 weeks after purchase of the drive and transfer of my files. I can tell you a good deal of information about this catastrophe, and what I am seeking is some sound advice. I know there are so many methods and applications which claim to do miraculous things, but I really have not touched it since this problem occurred yesterday. OK, here we go: Before my disaster, this was what my Seagate drive looked like when I ran fdisk -l Code: Device Boot Start End Blocks Id System /dev/sdb1 1 93062 747520483+ 7 HPFS/NTFS /dev/sdb2 93063 121601 229239517+ 83 Linux Without discussing how or why I made this mistake (trust me, I have beaten myself up way to much already), the following actions were taken by me on this drive which caused its damage: 1. Believing it was a USB pendrive (!!), I first formatted it as follows mkfs.vfat (only the first 1500MB) mkfs.ext3 (the remainder of the drive, so approximately 995+ GB were formatted as ext3. 2. Then, still not realizing I was tampering with my main storage drive, and having some problems with copying files to the "pendrive" (which was my Seagate), I started a dcfldd wipe on it. But my intelligence finally resumed as I noticed that the dd command was proceeding beyond 4000MB, and I knew something was amiss. I immediately stopped the dd command. Since then I ran testdisk, which did find the NTFS partition, and then Photorec, which allowed me to recover 100,000+ files without directory structure or names. I stopped that process midway through because that was going to be of no use to me. To aid in anyone's diagnosis or suggestion, after running Testdisk, here was the result: Code: Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121602 255 63 Partition Start End Size in sectors D HPFS - NTFS 0 1 1 121600 254 63 1953520002 D HPFS - NTFS 0 1 8 82862 254 63 1331194025 D HPFS - NTFS 0 1 15 93061 254 63 1495040953 D Linux 82863 0 1 121600 254 63 622325970 [Linux_Backup] D Linux 93062 0 1 121600 254 63 458479035 [Linux_Backup] Structure: Ok.

I am here seeking any other assistance I might find. The main partition of value is the NTFS partition. I am currently in Linux, but will use any OS necessary to recover these files even if I only get 80% of them, I really need the directory structure and names of said files. I purchased two one (1)-Terabyte external drives today to make this job easier, as I know I will need the space. I realize that by wiping the first 4GB I have destroyed the MBR and the file table... but I also know that NTFS is unique in the way it has meta-data throughout the filesystem. ANYONE....who could please offer some words, advice, tricks, hacks, magical spells, or incantations (I am open to anything), I would be greatly -- immensely -- appreciative. Please let me know.... I am near a panic attack as it is.. I know this is my fault, and that only makes it worse. Thanks, Paul :shock: New subject: Re: I may be smart, but after this, I should not reproduce.:cry: User avatar You wipe your drive and fill it with 0's there is no magic to repair this one.

How big did you think your pendrive is? There is plenty of commercial software you can try, but all give different results and some can even be destructive so choose wisely. You will likely lose any form of directory structure you previously had, and potentially many files will be damaged or overwritten. The only sure way to ensure all the required data you need is to consult a professional. Alternatively, look for some good software and be prepared to spend a few dollars on decent software. New subject: Re: I may be smart, but after this, I should not reproduce. The first thing to be done is to buy in another 1TB drive and make a by sector clone copy of your original!!!! Then you can mount the cloned drive in a system and run anything you want on it until you find a program which will give you the full file system & folder tree. There are many recovery utilities which have evaluation versions to try before you buy. If you find what you are looking for you should really recover to a 3rd drive. Good luck! Alexii New subject: Re: I may be smart, but after this, I should not reproduce. i had good luck using easus and file scavanger on formated drives for the recovery. Both have the ability to display the file/folder tree , but in ur case ,like it was said before , ull most likely get data raw. U can still shift through them by the extension. New subject: Re: I may be smart, but after this, I should not reproduce. User avatar Easus and file scavanger are worthless. If you need a good software take the advice of getting Get Data Back for NTSF, R Studio, WinHex, and USF Explorer. Then you have a better chance to get your data back using these prorgam than using Easus and receiving 500 x's the files after a scan on this one. This will not produce the files you are looking for. Follow the advice choose wisely your software and invest in it so you can try and get your data back. You might have to purchase more than one software to do this one with and then that is another issue on this one. Money and how much you will need to pay for all the software that can do this for you. Weigh out this cost and the cost of a good DR company who has the necessary tools needed to do this work for you. Then you can see which one is better for you to proceed with and get your data back on this one. Realize that some software packages can run you 500 dollars and up when doing this type of work. _________________ Iorana Haraharaini New subject: Re: I may be smart, but after this, I should not reproduce. Mater of opinion i guess. Easus and scav worked good for me. I do however have R-Studio and several other programs as well.

Broken HITACHI HTS722010K9SA00 Hello! I have a Lenovo laptop with this (SATA) harddrive in it. All of a sudden, the PC bluescreened and will not boot (into windows XP pro or Safemode). It says it is missing a critical DLL file and Windows will not start. I bought a SATA USB HD enclosure and plugged it in. Windows recognizes the adapter and drive, but says it is not formatted (!!) I looked around on this site a while and downloaded some utilities: I tried HDDScan but it just reports some basic information about the drive. I tried findandmount, but it just spins the drive for a long time and nothing happens (I tried intelligent scan and normal scan). Is there a basic guide for how to start recovery on a SATA 2.5" drive? If it comes down to a mechanical failure, I don't mind trying to open it up. I have to say it is not making any weird noises, clunking, scratching sounds, rattling, etc. ----- My only other prior experience with this kind of thing was a drive that failed and would not boot. I believe it was a boot sector virus, I was never able to boot off of it, but I put it in an Ultrabay tray and it works fine as a 'data' drive. Windows recognized the drive and I was able to copy everything off of it with no problems. This time it is not going to be so easy. newguy wrote: Hello!

Hello, First of all, get your drive, move to one real PC, and plug it in to the SATA or better to IDE port with SATA->IDE converter. Run MHDD (from boot CD), and scan the drive without reamp or erasedelays option. If you see any error or group (> 10 in short area) of coloured block, stop the drive and yourselfat this point if your data is valuable! If the scan can't find nothing interesting, you are faced with logical problems only. In this case use switchmbr command to disable the MBR and hide the partitions from windows. Than run any recovery program you want, and try to get back your data. BUT AGAIN: IF Your drive have any phisical problem, better to seek for professional help, because you can't precisely diagnose the condition, and you can't recognise if your drive have only some minutes left.... If you go to far, your recovery price will be doubled or tripled in any lab... Best Reagards, Janos Thank you NC! I Newed the above message from work. When I got home I hadn't seen your reply yet, but I had a proper PC with SATA support on the mobo and used that. The result was the same; the OS saw a HDD present, but claimed it was unformatted. I did some reading and searching and found out about R-Studio. I installed that on the laptop and tried to scan the Hitachi drive with R-Studio.

(etc.) I will experiment with MHDD on the other PC but I think I most likely have a physical problem with the drive. I have to admit, I don't have much prior experience with working on HDs specifically, but I am an EE and have access to a static-safe workstation in a clean room at work (and some fancy SMT rework equipment). I would really like to try to fix this and pull the data off myself somehow; I suppose I can order the same drive and do parts swapping if that would help. Read this before start anything: results-the-yourself-solutions-t11912.html?hilit=yourself%20solution Keep this on mind, hdd is a special case because have very high level precisity and a lot of special technologi inside. You never knows what easy looking step makes bigger problem... Janos I read it and understand the risks. Like I said I am just looking to learn something and accomplish something myself. Is there a way I can better determine what specifically has gone wrong with my drive? Thanks if i were to totally guess, being a laptop, I would say you jolted it at a bad moment, and the heads came lightly into contact with the platters, damaging those areas of the disk. some crap in there may be making things worse. you probably had not defraged the disk for a long time either (who does) so the files are scattered in small blocks over the platters. Some of these blocks are now unreadable, and therefore the files are corrupt. Thats what went wrong. The amount of data recoverable depends on the exact damage, and how much worse your attempts make things in the meanwhile. Hi Mediaman! Shouldn't the accelerometer in the active drive protection ensure that the drive is not in an unsafe condition while being moved? In order to get more accurate diagnostics, you will have to provide Terminal output. If you won't be able to do that, take it to a pro or forget about your data and move on. _________________ Don't gamble with your data! harddrivespecialist wrote: In order to get more accurate diagnostics, you will have to provide Terminal output.

I don't know what that means but if you suggest something I can read to learn, I will do it. When you say 'terminal' do you mean hooking up a level converter to a chip on the board and connecting to it with a terminal program to read diagnostics?

Shouldn't the accelerometer in the active drive protection ensure that the drive is not in an unsafe condition while being moved? apparently not. even it it was working, how good do you imagine those things are? they can only react in a certain time, and many rely on an external "watchdog" to trigger them. I would say a good knock accounts for 30% of the disks we fix. I would be interested in hearing other opinions as to how the damage may have been caused on this drive (lots of damages sectors in roughly same area of disk). As others mentioned, New a scan with MHDD (its free) and we will know a little more. Seeing the whole picture of unreadable/slow areas will help a good diagnosis. I can successfully start a scan but the problem I am having is that I can't get the .log file off the desktop PC I am using. I burned the .iso image of MHDD to a CD and booted off that. However it just creates a RAMDisk an operates from that. None of the harddrives in the system actually 'mount' in a way that the OS (looks like Win98 in command line mode) can see them, so I get a .log file that I can't get off the PC. The system has no floppy drive. I was thinking I could redirect the stdio to the COM port but there is no real rs-232 on this computer either (just USB). I saw that there is a version of MHDD that is on a 'Magic boot disk' which also includes USB Mass Storage support, so maybe I can save the logs to a USB thumb drive. If not, I will have to find a floppy drive and try that. 2:30AM here, will try again more tomorrow. Thanks again to everyone who replied. OK I salvaged a floppy drive from an old computer I had lying around so I can save log files from MHDD. MHDD correctly identifies the HD as Hitachi HTS7220. I did an EIT and SMART ATT and the drive responses appear valid. So I assume (perhaps hastily) a few things from this: -PC/MOBO/Adapter/Cables are OK -HD PCB is ok -System area is OK (if SMART data is good)? However, when scanning, the progress is VERY SLOW (I scanned a known good drive last night; it was a 150GB 3.5" SATA drive in the same desktop PC and the whole thing took just under 40 minutes) it runs into a bad block (unrecoverable error) every 3 to 5 blocks or so. MHDD recalculated the ETA every few seconds, and it varied between 14 and 24 hours. Because I didn't know if there was any physical damage I may have been making worse, I stopped the scan around at around 75000 (of 195,371,568). Hopefully this is enough data to make an educated guess at the root cause of the problem. I am uploading the scan log as well as a .WAV file I made; I put a microphone RIGHT ON the HDD; so the sounds appear louder than they really are. In operation, there is only a very faint sound coming from the drive. What you hear is a few seconds from the middle of the abbreviated scan that I did; you can hear the heads rattle faintly every time a red 'x' (bad block) comes up on the MHDD scan. PS: The board tells me .WAV files are not allowed. If anyone is interested, please let me know and I can change the file extension if that is permitted.

Probably one of the heads is dead. _________________ Don't gamble with your data! I think the drive has a minor ~radial scratch that makes a sector unreadable on each track, that's why it is slow. To be honest it is a job for a pro who can selectively read the drive head by head and skip damaged areas with special equipment. U can try imaging in reverse direction, but I don't think that will produce satisfactory results... Data Recovery lab (mumbai) _________________ - Data recovery When I was experimenting with MHDD I scanned a (good) 150GB SATA drive I had. I noticed a pattern; the majority of blocks read at the fastest speed (<3mS ) , but every few blocks, it read at a slightly slower speed (<10ms). This pattern was repeated throughout the drive until the very end. This made me think that there was something physical about that (good) drive that just naturally causes some blocks to be returned a little slower. I was thinking maybe the delay comes from switching from one head to another. The 'checkerboard' pattern I got on the good drive (<3mS vs <10ms) was very similar to the pattern I got on the bad dive (good block vs 'x'). So it makes sense to me that one head may be bad on the (bad) drive. My fear is that maybe the head crashed (contacted the platter surface) or fell apart (and is loose and rattling around in the drive, or is hanging on by the wires and can drag onto the surface). However, the drive doesn't make any weird sounds. With the platter spinning at speed, the air bearing should hold the head up off the surface, unless it's hanging sideways or something. So if it is like HDSPecialist says, and I have a bad head (that maybe is scratching the platter surface) it might be a bad idea to sweep the heads over to the end of the drive and try a reverse scan; because I'll be ruining the surface wherever I put that head. On the other hand, is it likely that I have a destructive head problem if everything sounds normal? I hope this is OK but I .zipped the .wav file to upload in case anyone wants to hear it.

Regards _________________ ZeBong First of all you should measure the MR sensor for judge it is worth a cleaning or not... To me the heads do not look all that dirty, but then again it's hard to tell just by looking at them. Sometimes I have really good results with cleaning heads and sometimes I don't. it all depends. Sure you can try to clean the heads before sourcing for a donor drive, you can't really lose anything by doing so. On Seagate drives after giving the heads a special treatment I can often recover some data. If only certain files are needed this sometimes works well, but if you need a full image of the drive, the chances are slim.

N.C. wrote: First of all you should measure the MR sensor for judge it is worth a cleaning or not... What measurement readings can be expected from good heads in comparison to damaged or dirty ones? MANDR wrote: N.C. wrote: First of all you should measure the MR sensor for judge it is worth a cleaning or not... What measurement readings can be expected from good heads in comparison to damaged or dirty ones? The best if you can compare with donor drive. :P Or with another head on the MHA wich is known good. Anyway, a good MR is from 22-250 ohm, it depends on the head type. The most of the longitudinar drives have 22-75 ohm, and the most perpendicular have 100-200 ohm. Janos ========================================================================== Very slow read and write speed I am using maxtor 80GB hard disk. My problem is it takes too many time to read and write. it slow the hole computer. Even it takes too many times to open drive, folder and when loading bios(checking component at startup). Data transfer speed is now in kbytes. I deleted all the partition and repartitioned, but no luck. I checked hdd using partition magic 8.0. surprisingly no error found. Same result for windows utility also. What the problem is this? what should i do? Note: I tried my hdd in another computer and same result. So problem is in HDD. i also made low level formating to fix the error. it took all most 2 hours to setup windows xp. my ram is 512mb. Thanks is advance. the drive is dying, degraded head/smart error leave the drive to thrash and continue with a new drive. _________________ __________ There is no substitute for education and experience THANK YOU SHAHI Is there any way to fix the error?? :( =================================================== How to reset S.M.A.R.T hard disk error I have some hard disk error Smart monitor but i need get data back When power on bios detect but request press F1, after i press F1 can't see it of cource not detect in windows How can i reset smart monitor error without hdd doctor (just use software) pls pls help me resetting a smart error is not going to help you get your data back. SMART information resetting usually needs special software wich is not free. But SMART error usually not prevent user data access, so Zero Alpha is right, it will not help you to get back your data. I suggest to seek for professional help if your data is important. Janos ================================================= Powerbook G4 Mac Recovery Hi I have a Powerbook G4 hard disk with MacOS and with user data. It was accidentally reinstalled with Mac OS using the CD.Now the user has a fresh copy of MacOs and no data in it. All the previous data is no more accessible. I tried recovery using R-Studio but nothing was recovered. Anybody knows better way of recovering ? Thanks in advance Cheers -Jag I don't think R-Studio is for Macs. Find a program that works with the Mac HFS+ file system. either way, just out of habit, i would always image the disk first and do your experiments on the second copy. It should be easy to image with any software as the disk probably has no errors. jono-ats wrote: I don't think R-Studio is for Macs. Find a program that works with the Mac HFS+ file system. R-Studio does work for HFS and HFS+ file systems. And it works on Macs :) _________________ My hobby is numismatics - http://coins.zoxt.net/ jag17 wrote: Anybody knows better way of recovering ? -Jag If you ran a complete scan using R-Studio and it found nothing then you may have to settle for a raw recovery, i.e. recovery by file type without folder structures or filenames. For this you can use either R-Studio or any other recovery software capable of raw recovery. Y'all are right. I guess it's just that we don't use it with Macs. Sorry! For some reason I have gotten better results with the Mac version over the PC version. I don't know why though. _________________ http://www.hddpros.com Only for professionals. ;) =========================================================== NEED PCB For Seagate Barracuda ST3750330AS 7200.11 750 gb Hello there. MY Hard Drive: S/N: 9QK13S8 - ST3750330AS - P/N: 9BX156-303 - Firmware: SD15 - Date Code: 09123 - Site Code: KRATSG - WWN: 5000C5000D89410. On PCB: UJAJ-6 - PCB 100466824 REV C - TS-M-8V01C SG - 0832-19-29. THNX Why do you feel you need a PCB? What symptoms is the driving displaying?? Probably zero size or permanently busy. In this case we have a PCB for you :twisted: Just kidding :lol: its burned. I can see the burned place.I can use a photo in that case. New a picture of the PCB, have you searched for "TVS" on this forum? Ok, Here are the photo. Image Image When i put the driver on power nothing happened, nothing work. If you put the hand on PCB you can burn the hand. I have buy 1 more Hard Drive: S/N: 9QK0X7Q6 - ST3750330AS - P/N: 9BX156-303 - Firmware: SD15 - Date Code: 08525 - Site Code: KRATSG - WWN: 5000C5000D5838E2. The drive work but slow my PC in start and i can see the hard drive only on my device manager. The only thing i want is my data. Any idea will be great, knowing the price for recover start from 800 to ****** euro. Thnx a lot for any idea. Sorry.... i have put the PCB of the new one on the old driver You need to swap the 8-pin serial EEPROM chip in the top LH corner from patient to donor. BTW, are you saying that the two 4R7 inductors are getting too hot to touch? No, that 2 are burned (i'm sure, there was black dust around the circle). When u put the hand on PCB in the midle its very hot after 6-7 sec of work. I can change the 8-pin serial EEPROM chip on new PCB. I try. Thnx for the reply and help. Ok, I have change the 8-pin serial EEPROM chip but now i can see my drive only after a long time on my computer and i try to install new windows on it (because I can see normally on bios) but i can make a fresh copy only if i format the drive.... Any idea.... thnx...
