I have a fileserver running Server 2003 R2 SP2.
The server has a C, D and E drive.
The C and D drives are created from 2 X 300GB drives in RAID1.
The E drive is created from 4 X 300GB drives in RAID5.
I recently received an alert stating that the E drive was running out of disk space. In My Computer the E drive shows as having a 836GB total size with 79GB free. When i run SizeExplorer Pro on the E drive it shows as having 580GB worth of data on the drive with 84GB free. Therefore SizeExplorer Pro sees the E drive as having a total size of 664GB ? Why do My Computer and SizeExplorer not tally ? Where's the missing GB's ?
