So i think i lost a hd in my raid 0 array. when plugged in i hear it spin up but is not recognized in bios or by seagate utility software. Before i reformat the one good drive i have left, i was wondering if there was anything i could have missed. I hate to loose all my data.
It will depend on what broke on the old drive. If the PCB failed you could buy another identical drive and just swap them over. Assuming you made no changes to the other drive it should just boot up like nothing happened. If however something else in the drive failed, your F'ed. As Foscooter said, you are talking many 100s of dollars if not $1000+.
