I hard drive lba couldn't boot into Windows, so I tested the hard drive using Samsung's Utility available at: http://support-us.samsung.com/cyber/popup/iframe/pop_troubleshooting_fr.jsp?idx=51176&modelname=HD250HJ1 On running the scan, I see that the disc has LBA errors. What exactly is an LBA error? any way to salvage the data, or the Hard drive? hard-drive share|improve this question edited Sep 22 '15 at 15:10 bertieb 2,55851226 asked Jul 21 '10 at 17:15 Devdatta Tengshe 82081327 add a comment| 2 Answers 2 active oldest votes up vote 9 down vote accepted the Hard

drive check utility had suggested that I format the Hard drive. Does that mean that I can safely use the disk after a low level format & it won't have any issues? If you provided more information both about the model of drive you are using as well as about the errors the Samsung utility reported you might get better answers. Without knowing the details of your situation all we can really do is speculate. Well, that, and perhaps wave our hands wildly in the air for emphasis. LBA is an acronym for Logical Block Addressing. In this case I assume it is just another, possibly more technically accurate way of referring to a "bad sector". Unless your hard drive is very old, the file system of your OS probably didn't even know anything had happened. For a while now the firmware in hard drives has been transparently handling sector write errors by remapping the sector to another location on the drive. If you were able to copy all the data on this drive and no errors were reported it seems quite possible that the offending sector was not even being used (yet) by your file system. The bad sector may have only been discovered because the Samsung diagnostic tool you used performed a complete scan of all sectors on the drive. The first thing to do in a situation like this is to save your data, which you've done. Next I would recommend that you

HDD - Seagate Barracuda LP 1.5 TBModel - ST31500541ASFirmware - CC94Issue - Drive would appear mounted, and seatools for windows a logical letter would be assigned to the drive. However, when trying to access the drive on windows 7, and clicked on it, it would take crystaldiskinfo forever and nothing would come up. Device Manager would show the drive, disk management would not. Fast forward a couple of months...Drive wasn't recognized in BIOS, or windows 7 or any where else!!! Two weeks ago, I needed my daughter's baby pictures from http://superuser.com/questions/166177/hard-drive-lba-error-how-to-proceed the drive, and I connected the drive as internal (SATA) and tried to access the drive. The drive suddenly appeared mounted but nothing happened. Tried Recuva recovery and other free trials - drive would appear as if ready, but when selected for recovery, it would take forever...tried HDD regenerator (scan and repair) - scan would run till 47MB and then an error would pop-up saying 'drive is not ready'. Drive was connected as IDE compatible. Other software's were all the same.Two days ago, I brought a http://forum.hddguru.com/viewtopic.php?t=25112&start= WD 2 TB drive and since then I have been trying to clone/image - and so on...tried Acronis and i would get an error saying ' failed to read sector 63 on drive 4'...i would have to un-plug the usb cable, and then an 'ignore sector' button would appear, and this took forever...guys from my work from the helpdesk, gave me an 'universal boot cd' to try, and when i used the HD Tune up and scanned the drive for errors, only one error popped up.Finally, after endless hours of browsing and reading, I ended up on HDDguru and started HDD RAW COPY Tool V 1.2. The software not only recognized the bad drive as a source (miracle really), it also was able to lock it, and was able to progress and ask for target and so on...Issue: - Since the copy started around 3 hours or so ago, there have been many many errors (similar to the one below)- Quote:1/22/2013 8:08:04 PM Read Error Occurred at offset 5,523,832,832; LBA 10,788,736Error seems to happen at every 4096th LBA sector; and at every '2097152' offset - in incrementsQuestions:1. With all these errors being spit up, do you guru's/experts and god-like beings, think, an Raw copy is being made successfully?2. current sector is at 10,919,808 but the progress is at 0% complete (i understand that this disk has a total of 2,930,277,168?3. Lastly, can you tell me whether the tool would have spit out an error by now and would have likely aborted if the RAW copy p
similar to thismessage: [3142.686141] end_request: I/O error, dev sda, sector 31415926 No matter how often you read the block, https://techoverflow.net/blog/2015/01/07/fixing-bad-blocks-on-hdds-using-fixhdd.py/ the hard drive still returns an error and does not reallocate theblock. Background: Hard drives are programmed not to reallocate the block until someone writes to said block. This means that for normal users the program reading the bad block probably won't fix the error by itself as most programs exhibit read-before-write usage patterns read error often resulting in a crash before any block is written. By using fixhdd.py, the script presented in this post, you can force your Linux-based OS to rewrite the blocks, effectively fixing the block errors if the HDD has reallocation space left. Usage of said script is only recommended for professional ITpersonnel. Solution: You can use read error at this script, fixhdd.py in order to automatically write the blocks yielding errors. While the data stored in those blocks will be lost forever, you won't any read error after writing toit. Syslog monitoringmode fixhdd.py operates in one of several modes including automatic sequential scan. The most straightforward mode, however, is to continously scan the system log for error message like that outlined above. The tool automatically extracts the LBA (logical block address) from the system log and writes it using hdparm (use sudo apt-get install hdparm or equivalent if not alreadyinstalled). In order to use this mode,run sudo fixhdd.py --loop /dev/sda in the background. In another shell, run the program yielding the error message repeatedly until the file can be read without an error. Every five seconds, fixhdd.py will re-scan the syslog and attempt to rewrite all damaged blocks. When finished, stop fixhdd.py using Ctrl+C. Sequential block scanmode After these errors are resolved, I recommend using smartctl -t [short|long] to r
