Ultra DMA CRC Errors

[quixotic]

Windows 7 x64 starts behaving strangely when I copy a large file to a certain extended volume of 2xWD20EADS (I have a few, but only one became problematic). It gradually stops responding: things that are already open continue semi-normally, e.g. start menu, but it wouldn't open a new application, cancel the stuck copy operation, access the internet, or shut down the computer. The drive obviously has no system or application files whatsoever.

I used HD Tune to take a snapshot of health yesterday and then another today and, apparently, the Ultra DMA CRC Error Count is rising, probably 1 each time the above happens, now at 6. All the other drives have 0. Complete chkdsk showed no errors. Is that drive dying? And is there a way to stop Windows from 'freezing' when it accesses it, at least until it's replaced?

Reattach your SATA cables first. If the errors still increase change the cable and/or try a different SATA port on your mainboard. If that does not change anything you should get your data off the drive as soon as possible.
