Testdisk Read Error Every Cylinder
are voted up and rise to the top Hard drive LBA Error: How to proceed? up vote 3 down vote favorite 3 I have a hard drive (a samsung product). I 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 testdisk analyse cylinder read error 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 th

Device Manager would show the drive, disk management would not. Fast forward a couple read error 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 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 read error at 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 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
sector? Bad sectors can happen from physical damage on the platter's surface, a faulty or failing read write head or system area corruption, which can also cause a sector to fail the ECC error checking control checksum. Remember if data is important please consider the experts! What are Sectors and Bad Sectors? A sector is the smallest unit of data on a hard drive. A drive's platter is divided into tracks, and then the tracks are divided into sectors. Each sector has a specific location called its Logical Block Address (LBA). A bad sector is a sector that has damage and can no longer be used to store data. Bad sectors can occur through normal use of a hard drive and a properly functioning drive has a built-in process to work around them, the data that runs this process is stored in the drive's system area. When a hard drive finds a bad sector it will reallocate it; it moves the bad sector from its current LBA and places it in a defect list (a section in the system area designed to record defects), it then copies the data from the bad sector to an empty and working sector. Causes of Bad Sectors Failing read write head A read write head that is failing and unable to read a sector or an entire platter will label the sector(s) as bad, this is a 'false read' because the problem is not the sector, it is the read write head. This type of failure is very common. Corruption of the sector location data If the LBA is lost, the sector can no longer be located and is marked as 'bad'. The defect list is full A hard drive's defect list is allocated a small portion of the drive. If a drive has too many defects and the defect list reaches its capacity, the drive can no longer reallocate the bad sectors because it has nowhere to store them. Note: this can sometimes cause a drive to click or be inoperable. Physical damage to a sector caused by dust or particle contamination If a drive is opened outside of a clean room environment, the dust or other airborne particles in the air land on the platters. A hard drive has millions of sectors therefore an individual sector is extremely small and even a microscopic particle can physically damage it. This is why it is very important not to open a hard drive if your data is important, take your drive to a company with a certified clean room. Removing the lid for just a couple of seconds is enough to cause contam
