6 spindles:

4x136GB -> 2 RAID1 volumes -> C-drive and D-drive

2x300GB -> 1 RAID1 volume -> E-drive

I hope they upgraded all hardware drivers before they made it available because that...

On Win2K8+, you have to create a volume that is >=4GB for it to be sector aligned on 1024K. What most don't realize is that most servers ship with...

I cannot give you the details you seek, but can provide the following input/responses:

Here is a portion of the complete result set. I need the program to look at the curItem as compared to the prevItem and if there is a...
