Back to the mundane...
Sep. 4th, 2011 09:28 amI set the disk recovery program going yesterday at around 3 pm with everything plugged into a UPS. As of 6:30 am this morning, the scan was still showing 1% progress with about 7 hours left to go.
That makes no sense to me, but I can wait 7 hours to see how things turn out.
Interestingly (and something I didn't notice the other day when I ran the program for the first time), the software reports that the disk it's scanning has a 2-TB capacity, whereas the label says it's a 1-TB drive.
I therefore suspect Western Digital manufactured the hardware to be a 2-TB drive, but something during the quality control caused a downgrade to a 1-TB capacity. (Back in the day—and still, as far as I know—memory manufacturers used to do analogously the same thing with memory chips: build 'em all to operate at high speed, and sell the ones that failed the speed tests as not-quite-as-fast memory chips, provided they passed all other quality tests.) However, in the case of a disk drive, I can't easily visualize what kind of non-fatal flaw might still allow a drive to be sold as a lower-capacity unit.
Cheers...
UPDATE: As of a few minutes short of 10 pm, the "time remaining" is 16+ hours and the progress bar is at 3%. This suggests that (a) the time figure is not reliable, and (b) it will take the better part of a month (!) to finish scanning the disk to see what, if anything, can be recovered. We shall press on.
