Most people get inpatient when if comes to the SnapOS doing checks. If it's hung in the 5% area of the HD, it's may not be good. This is where all of the disk stores it's markers and drive allociation tables.

You can switch the PS if needed.

Your right if you kill drive 1 you will have 2 drives failed, then it's SOL.

SpinRite after you download it , gives you options to make bootable CD & floppies if needed. What I do is remove/disconnect the windows HD's and install the drive from the 4100. Then boot from the CD. You then select what you want to do, maintance or recovery mode. If during maintance it incounters a problem it will automaticaly switch to recovery. If it hangs on the 5% area for more than 4 hrs the HD is toast. If you have 2 working drives of a 3 disk array, you can install a new HD into the failed drive position. Then you will need to make it a spare. Then set back or let it run over night and see if it rebuilds the array.

If you need the data you may need to contact Snap-Tech for recovery service.

Now if drive 1 is bad, ide0 you must install the same size drive. You can remove your hot spare, do a quick format and install it into drive 2 (failed drive). Boot the snap once it comes up make the clean drive a hot spare. Then leave it along while it does it's thing.
