Cloning of disk hangs after "Error: unable to read disk 2 sector xxxxxxxxxx"

Thread needs solution

Hello,

I am trying to clone my entire OS from a Seagate 500GB ST3500410AS to a new Western Digital 640GB WD6410AALS, using Acronis True Image WD Edition. PC is running Windows Vista SP1.

The Seagate developed some bad errors and I made a data backup already but I was hoping I can clone the disc with OS boot-able so I don't need to re-install everything and only lose the data in the bad sectors. Acronis locked the C drive and rebooted in DOS mode and started the cloning (one partition on each disc, cloning from 466 GB -> 596 GB).
At 76% "ERROR: unable to read disk 2 sector xxxxxxxxxx" (Retry, Ignore, ignore All" was shown. For the first message I tried "r" and the same error for the same sector was prompted, so I pressed "i" and another error came up for the next sector.
Then I pressed "a" but now the cloning seems to hang, it has been more than 2 hours and there has been no progress, it's still stuck at 76%.

What should/can I do now? Can I just reset the PC and will it start with the original (Seagate) disc since it has been locked?

Appreciate any help.

Run Chkdsk X: /f /r on the Seagate disk first. Where X: is the drive letter for the Seagate disk. Afterwards make a backup of the entire drive and validate the backup archive you create. See http://forum.acronis.com/forum/3426 section 7 for useful guides. Also see http://kb.acronis.com/content/1871 and http://kb.acronis.com/content/2770 for more help.

Thanks, but how do I get out? Just reset the PC and disconnect the new drive, then boot with the old disk?

Yes. You will have to boot from the old disk so you can run chkdsk.

Chkdsk reported an "unspecified error" and then "autochk program not found". I am giving up on the cloning since I have spent too much time without any progress now and will do a clean install on the new disk, something I should have done from the beginning I guess.

Thanks for your help though. :)

Better solution is to tell ATI to ignore bad sectors when reading from the old hard drive and cloning to the new hard drive. This was the only method which worked while I cloned a friend's failing hard drive to a new hard drive.

That's what I tried (see first post) but it never went beyond 76%, even I waited several hours. Anyway, installed the OS and most applications on the new WD drive yesterday, so no need to clone the old one anymore.
