hmm so if one my raid HD dies... then my whole array is dead rite ?
is there anyway i can at least fetch some informatin on the other good HD in the raid setup ?
 
depends on the RAID. if its raid 0 its unlike since it puts data on the drives likes its one drive however there may be some utility that can transfer the files that are still ok
 
Nope, when one drive dies in a RAID 0 array, your data is toast. Speaking from experience on this one, unfortunately. 🙁

Yup. The surviving drive only has half the information it needs. There's no way to get the other half of the data back without restoring it from the dead hard drive.
Example: take a book, closed, and tear it right down the middle. Now try to read the book using just one of the halves. You might be able to get the gist of it, but not easily. That's using human intelligence. A computer would do far worse. And just reassembling a few pieces of some software doesn't cut it.

RAID 5 (mirroring with parity) or RAID 0+1 (mirrored striped volumes) provide performance and redundancy, but they do cost more. RAID 5 needs a fairly expensive controller, and at least 3 drives; RAID 0+1 can be done with most standard RAID cards, but it needs at least 4 drives, and they need to be added in pairs.
