More about : unable read sectors device rwgwiccan 15 February 2012 23:55:02 Well the problem here seems to be the fact that you deleted the partition which for all intents and purposes basically deletes all the information on the drive. I would suggest using a data recovery tool rather than a partition recovery tool. You could try Recuva or another data recovery tool as long as you have not rewritten any information to those drives. m 0 l Best solution inzone a c 121 G Storage 16 February 2012 00:20:20 http://www.cgsecurity.org/wiki/TestDisk This is a free software program for data recovery so you could try this.

Login to post comments 4 replies [Last post] Fri, 2011-07-01 18:07 John Ahlberg Offline Beginner Joined: 2011-07-01 Posts: 1 I did plenty of searching before deciding to start a new topic on this but I couldn't find a straight answer. I have never made an image on this machine before and it is now giving me smart errors. I installed ATI home https://forum.acronis.com/forum/22472 and tried running a full backup but it kept throwing errors saying it can't read sectors. I ran chkdsk c: /r and it completed successfully but I continue to run into the same issue trying to make a full backup. I'm currently running a full backup and ignoring all errors but I'm not really sure what that means. Will a restore of that image work on the new drive? Will the new drive also have corrupt sectors after the restore? Would doing a clone offline make anything better? Will resizing the partition help things? Any other suggestions? Thanks in advance.

Depending on what is causing the errors will depend whether the corrupt sectors can be marked as bad by either the drive firmware or by Windows when the image is recovered or if being hardware errors they are missing altogether in which case they are unrecoverable. If you ignore all, this just means TIH will not tell you it found a problem.
surface scan. Repair bad sectors in-place (if there are few) or clone a disk (if there are many). Disk Read Errors Data can be lost due to unreadable or 'bad' sectors. If a file occupies a sector that returns an error on http://www.diydatarecovery.nl/kb_badsectors_article.htm read, the file will become unusable. If there are too many bad sectors you may even be http://forum.hddguru.com/viewtopic.php?t=20427&start= unable to access an entire volume. If the MBR or a sector that contains a partition table or boot sector can not be read, the entire disk or drive will become inaccessible. Bad sectors in a system area are a recipe for disaster. There are 2 ways of dealing with data loss due to read errors: 1. Clone the disk to a "known to be good" disk 2. hard drive Repair bad sectors in-place If you have reason to believe a disk's condition is rapidly deteriorating, always clone the disk! If a partition was lost because the partition table sector could not be read, apart from repairing the bad sector you will also need to rebuild the information that was in that sector. Cloning a bad or corrupt hard disk To be able to clone a disk with read errors or logical corruption you will need a data recovery utility that is designed bad sectors on to cope with this type of error. The tool of choice must gracefully handle read errors and get as much data from the source disk as possible. It should ignore any (corrupt) logical structures on the disk. A successful strategy to copy as much data of a disk as possible is doing multiple passes. In a first pass try to avoid disk hangups by not trying too hard and skip over errors. The cloning software keeps track of the areas it skipped and processes those areas during the next pass. DiskPatch clones disk to disk using a 2 pass clone. iRecover writes a raw image file that can later be processed, also using a 2 pass clone. Repairing corrupt or bad sectors If a sector's data is corrupt, it can often be reconstructed using ECC (error correction). If the sector is too unreliable to store data again, it will be reallocated; the sector is taken out of service and replaced by one from the 'spare pool'. The spare pool is a group or multiple groups of spare sectors available on any modern hard disk. You can detect unreliable sectors by scanning your disk's surface with DiskPatch. You can check the state of the disk by running a disk health check (S.M.A.R.T. check). iRecover also can check a disk´s SMART status. If the data from a sector can not be read even after error correction, it becomes pending for reallocation; it is not yet automatically swapped. On write a sector is reallo

I dont now how to proceed.* The drive behaves the same in two different computers* It is a non-OS drive, just for storage* When it is used, windows gets stuck at startup, when hard drive is removed windows loads perfectly fine. So I cant look in Disk management etc. * The dead hard drive is visible in BIOS* I have not done anything yet, such as fixmbr etc* Knoppix finds the drive, but it only contains system volume information, all files are gonePlease help....
