I have a problem i got a 400 gb HDD it was partitioned in 2 200gb each drive. i reformat the drive c: to install a fresh OS (Windows XP SP2) I partitioned the drive into 40gb c:drive & 160gb in the other drive. I used the one in the windows installation during set-up. Then after I partitioned the c: into 40gb & 160 gb there goes the problem. It only allocated 131gb all in drive c: the 200+ gb was unallocated. But when I transferred the drive in my other computer and installed PowerQuest PartitionMagic.v8.02 I manage to recover my 400g space and partitioned it smoothly. But when I put it back in the original CPU the problems is still there, still 131gb allocated. What cause these problem? is the motherboard (P5P800-vm) has to do with this prob? the unit that it was installed is Intel Celeron D, ASUS P5P800-vm motherboard, and the hard drive is Seagate ST3400832A.
For now I'll try to use some disk rescue software.
still need help
