Windows Setup should now show both drives according their order in the BIOS.

Hi all,
I'm struggling to find any documentation on this, I know the Dell PowerEdge 2950 supports both SAS and SATA drives but I'm not sure if I need to anything to swap them over, do I need new caddies for example. Can I just swap the drives?
Many thanks...

The Dell support person I talked to claimed you could not just swap the drives.
There are exceptions, but they're a few weeks ago.
As a general rule, wherever you have SAS drives you can use SATA.

I'm designing a file server based around ZFS and I'm considering using USB flash drives in RAID 1 as boot devices. It seems that few people do this, and I'm wondering why. From what I see, using USB flash drives have some benefits:

The SD cards in dedicated readers have some distinct advantages, I think, to USB flash drives.
The readers are just attached to an internal USB).

Copy the files from your USB drive to the shared folder in Windows 7 the USB drive shared but I do not recommend this.
Shared Folders for your XP install.
