Saving Data from a crashed HDD??

[scamper]

How can I retrieve data from My Crashed ( detected by Bios & Device Manger- volumes show blank:confused:) but not visible in My computer.
The Drive is a SATA 250GB Segate on an AMD system in a RAID O array with only pure Data:(

if it is visible in Device Manager, go to administrative tools, system management and open Storage Devices/Storage management and try to mount the drives. If not try using softwares like RecoverMyFiles or the SeaTools

just try a live linux distro to do that.your partitions might be detected
