This does not sound like a subversion problem - the effects are too low
level. I'd suggest:

* check all the cables inside the machine - is there a sharp bend or even a
break in the data cable to the disk? If yes: try to replace the cable.

*maybe the cable is corroded: try to remove it and then place it back again
(happens sometimes in environments which are humid or contain corrosive
gases - such as bed rooms or factory floors).

*does the hard disk make "funny" noises? Did you try to check it (I'd run
badblocks on Linux, but I don't know what the Windows-equivalent is)?
Replace the hard disk...

*does it happen only on this disk or also on other disks attached to the
same station? If others: might be a driver problem.

*How is the disk set up in the BIOS and/or Windows? Maybe you enabled a data
transfer mode that's too fast for the hardware. (Try to set it to a slower
mode, DMA is ok, but overclocking the cable sometimes skips data.)

*Does the box often behave more strangely than it should (considering it is
already running Windows): very frequent crashes (at least twice as much as
identical boxes), strange data corruptions? Might be a problem with the
memory chips - check them with a memory test program, check that they are
properly cooled (ie. cables don't block the air flow towards memory), check
that they are not overclocked in the BIOS.
