I got an Intel Server Chassis SR1500. Since there are 3 slots for hard disk, I put 2 Seagate Barracuda 7200.10 320GB to Slot 0 and 1 to make a RAID1. For the last slot (Slot 2), I put a Seagate Barracuda 7200.11 1.5TB, make it another set of RAID1.
The operating system is Microsoft Windows Server 2003 R2, installed in the 1st RAID1 group. The 1.5TB is used as a share drive for around 100 Windows XP/Vista users.
The 1.5TB corrupted after running for 2 days. In Event Viewer, it said "the file system is corrupted and unusable", reported by ntfs. Files are corrupted and CHKDSK rescued some of the files, in a hidden system folder called found.000.
I am curious, what are the possible causes of the corruption ?
