When running Recuva on a drive I recently wiped and haven't since put data onto, It found 6657 files, then instantly crashes.
System info:
Windows XP Pro SP2
AMD x2 4600
2GB DDR2
2 x 320gb Seagate Sata II
MSI K9A Platinum
ATI x1900XT
(In hindsight... its all in the screen shot ;-) )
I can give you more information if needed.
