Went into my home server to find a Drive letter missing - my 750GB RAID Data drive with 4 members - 3 250GB drives. I panicked. I opened the Adaptec Storage Manager expecting to find the array needing to be rebuilt. 3 Physical Drives were listed as optimal and the 4th on port 3 was rebuilding. Odd, the array should still be accessible, I thought. Logical Drive showed as FAILED and OFFLINE, its size was being misreported as well as a full TB....
I shutdown to go into the Array Config on boot.
Got the following message:
Following arrays have missing required members and cannot be configured - Array#0-RAID-5
Pressed Ctrl-A to enter config
Screen quickly listed 4 physical drives and said No Logical Drives Found
Configuration has changed, press Enter to accept current config (I pressed Enter)
Array Config Utility:
No Arrays present.
--Create Array (I couldn't proceed with this - all drives full?)
4 Drives listed, all 0KB
--Initialize Drives (I didn't proceed with this)
4 Drives listed, all 232.7GB

I have no idea where to go from here. I've read as many other posts on this site about this problem and none seem to apply to me. I read about RAID reconstructor but a this point I don't have an additional TB of space to write a RAID image to. I need ideas and preferably a way to get the array up long enough for me to just get my data off.
