Bad block issue refers to the problem with your hard drive. If you restored to the same drive – it is expected. Kindly, check your hard disk with check disk (full scan), at some point third party tools, mentioned in this thread, are better in terms of bad block detection.

Hi Dima. I've done some experimenting and I think there is a problem with "bad blocks skipped" messaging. In my case, it correctly appeared for my original disk and I managed to make a complete backup using "SkipBadBlocks (DWORD) = 1" in the registry. I then restored this backup to a new disk that had no bad blocks, and confirmed that backups from the new disk ran fine with "SkipBadBlocks (DWORD) = 0" (as I would expect). But if I left "SkipBadBlocks (DWORD) = 1" then I got the "bad blocks skipped" message, which must be a carry-over from the first disk affected by bad blocks but isn't appropriate for the new disk. In fact, I wasted quite a bit of time testing the new disk for bad blocks because of this message. I appreciate that you would want to flag in some way a restoration from a backup with skipped blocks, but not with a message that indicates that the new disk onto which the backup was restored itself had bad blocks. Sorry if this is posted in the wrong thread, but I haven't seen discussion of the SkipBadBlocks functionality anywhere else.
