NV+ Bad Disk #1... Replace with unit on or off?
Hello,
I'm having some issues booting an NV+ with a bad disk (unit has 4x 750GB ST3750640AS in XRAID.)
Initial problem was reported as a dropped network share for the local workstations accessing the unit. Upon investigation, the NV+ unit was found to be locked up and completely unresponsive - lcd panel off, no messages, no email of failure. Shutdown was not possible via the power button or admin control panel, so cord was unplugged.
Reboot attempted with all 4 disks in; hung on FS Check, powered down again via power cord after 10+ hours sitting hung.
Reboot #2 attempted with all 4 disks; this time was able to find unit with RAIDar, wich reported the correct used/free space size of volume C, but showed significant error count on disk 1. Some errors on disk #2 and disk #3, none on disk #4. Boot process finally hung, unit dropped off of RAIDar, and was unresponsive via power button. lcd reports "booting..." Power cord pulled to shut down.
Next attempted booting with one each of the 4 disks removed, results as follows:
disk 4 out = hangs on boot
disk 3 out = lcd reports "bad disk found", then hangs on boot
disk 2 out, attempt #1 = lcd reports "kernel panic"
disk 2 out, attempt #2 = lcd reports "bad disk 1"
disk 1 out = successful boot, no shares, no volume data, disk 2 shows 16GB free, disk 3 shows 16GB free, disk 4 shows 696GB free. lcd reports proper IP address and 0GB used/0GB avail storage info.
My question is this: Do I replace disk #1 with the power off then attempt to boot, or do I boot with disk #1 removed and then plug in the new drive after unit has finished booting? ...OR... are neither of these a good idea?
Thanks in advance for any assistance in this matter.

What is the likelihood that doing so would damage the data on the other two disks, etc.?
I'm considering the cloning route, but my cloning tools are windows-based. Not normally an issue, but the PC wants me to initialize the disks as MBR or GPT so they can be seen by the logical disk manager - can't see them in the cloning software if I don't; however, I'm concerned that this would make an irreversible change to the drive, thus rendering any other attempt to clone or sync impossible. Thoughts?- Don't initialise the disks.
So you don't have a Linux machine?
