I recently built a new PC (XP Pro SP2) and tried to install 2 of the drives (80GB WD IDE) in it from my old PC (each has 3 NTFS partitions). They show up in device manager as working properly but Windows does not give them drive letters. When viewed in Disk Management, it shows the correct size for the disk but shows the partitions all screwed up, with small data partitions and unallocated space between them. My new PC has 2 500GB SATA drives in a RAID 0 configuration. Any ideas on what's going on?
