I hope so much that someone here can help me (very worried). I was having trouble with my RAID5 recently. Drives were coming up as failed or missing. I was able to get them all back except for two...one said failed, and the other said missing. However, I tried many times to remove and re-insert the missing drive. It would not come back up. So, after reading online, it seemed an option was to delete the RAID set and then re-create it. I did so, and my D and E drives were both visible as they should have been. The D drive seemed to work also. However, the E drive did not work, which is the vast majority of the content (the D drive is about 750 GB, and then the E drive is the rest of the 15TB). I remembered that I didn't select the "Greater than 2TB option when I re-created that RAID set (I thought the option was only if your operating system did not support more than 2TB...mine does...Windows XP x64). Since the other one worked, though, and it was not greater than 2TB, I figured that's what it must be. So, I went into the volume set options and changed that setting. It didn't say it was going to erase the disk contents, unless I missed it (I have 3% of my vision...so, it is possible, although I was looking very closely since this is extremely important to me). Yet, it began initializing, which to me means bad news. It was at about 15% by the time I got into the web admin to see what was happening now. I shut down the computer, turned off the drive boxes, and then rebooted so that I could send this message. Firstly, is it indeed erasing all my data? If so, can it be aborted/reverted at this point (long shot, I guess, but I am hopeful!)? I very much hope someone here will have good news for me. Thanks much in advance.
