I'm annoyed that I accidentally deleted the two hard drives on the machine; they were in RAID 0 form and I had the option to delete any RAID disks but I didn't know that would wipe them. I thought it would simply make them non-RAID and leave all the data on them. I don't know how to undo this operation.
iqs - that is the computer I have but where are the SATA drivers in there for me to put onto a floppy?
If it is a bootable install disk of XP then download n-lite and sp3 for XP. You can then use n-lite to slipstream sp3 with your current Windows disk to create a new disk that will recognise the SATA drive in your Dell. I have just done a similar installation for another of my computers.
