The main problem is that the file system sucks NTFS and alot of motherboards are not supporting it perfect.
Mine either here, It sucks but i did life with it, Im having a shitload of corrupted data here and still after 1 year no SOLUTION!!!
Only solution is to make it a fileserver for linux then its working good.

I had the same problems when i rebooted, i reinstalled windows and it worked 1 week again, i did this for 1 month, did replace to drive to 120gig and PROBLEM SOLVED!!!
its for sure the drives and i did talk to some friends working at computer stores and they are saying the same, only problems with 250GIG's they are getting data corruption and no solution, safe way is to get 120GIG's
