I have an old Optiplex 170L. It came with a 65 GB or so IDE hard drive. I added a 1 TB WD HD and transfered all contents to the new HD and erased and disconnected the iDE drive. Now I want a RAID 1, so I bought a second identical 1 TB WD hard drive and a SYBA 2 esata and 2 internal SATA PCI card. The problem is if I install the PCI card for the RAID, it will erase my data. So how do I transfer the data to the new RAID 1, with out having to buy an external disc? Can I transfer all data back to the old IDE drive. The install the PCI card, add the second WD drive and set up the 2 WD drives in RAID1 and completely reformat the drives. Then connect the IDE drive as the bootable drive and copy data back to the RAID WD drives. Then disconnect the IDE and make the WD the bootable drive? I am not sure if I can do it this way? Any suggestions appreicated.
