I have an older Mac Pro 2 X 2.66 GHz Dual-Core Intel Xeon with my boot HD a 500 GB SATA and 2 extra 1 TB drives. One of the 1 TB data drives is reporting a mechanical failure. I tried to fix it using Disk Warrior and it couldn't. Disk utility is telling me to back up as much as I can, reformat the disk and restore my files. The Drive is not showing up on my desk top but is seen by the two utilities. I think i should send this disk out to have the files recovered. Does anyone have a good company they can refer me to and what should I expect to pay for this type of service? Any suggestions would be appreciated. Thank you!
