So, here we go, I have a Windows 2000 Server already fully installed with 2 scsi disks, one for O.S. other for backups (it's a backup server). Now i want to had two 260 GB external usb disks (because i have no space inside the box) and want to put them mirrored ... The problem is ... When i try to convert them to dynamic, the "convert to dynamic" option appears "greyed out" and i can't select it, if i go to the previous installed scsi disks i have the "convert to dynamic" option available ... Anyone knows what the problem might be ? Thanks in advance, and sorry for the very bad english, Nunoc
