Samsung Spinpoint F1 problems

[trunksthebattler2000]

So I bought a pair of 750GB Samsung Spinpoint F1 drives the other day to mostly good reviews (should have read the bad ones too, oh well) and whenever I try to use them for anything other than installing an OS they cause the whole system to lock up. From what I've read the people that seem to have problems with these drives also have nVidia chipsets. Does anyone know of a fix for this? Also I find it very strange that there is no issue what so ever when installing Windows XP Pro but if I try to copy amounts of data as small as a few MB the drives cause the system to lock up. Any ideas on this? More questions and comments to come. Posting now so I don't lose this when I try to run diagnostics on the drives.
