I ran checkdisk with error correction, and it seems to have finished and done its work, but still, when I made a partition backup using Acronis Home 11, I got 2 error messages saying it couldn't read some data - I told it to 'try again' and it didn't give me any more error codes.) The number of sectors affected seem to climb abit with each boot - think 99 was the last number.) And I've found at least one, and by other methods more, sectors with data that I get a 'can't read that' error. Easy part: I have a laptop WD drive that is starting to show signs of failure (Smart parameters warning, on some SMART versions, the 'Current Sector Pending Count' shows a red circle with a bar across it. Bear with me, as I have a couple Q's that can be a bit complex.
