February 27, 201115 yr Author Joe, little update on this... I was messing around in the BIOS settings (M4A785-M Mobo) and decided just for kicks to change the drives from AHCI to IDE. Then when I started unRAID, the problem drive no longer shows as unformatted. It now shows as "missing". When I got to devices, it is there as an option in the dropdown. This time I think I'll wait and see what you think I should do next...I'll also attach my syslog. syslog-2011-02-26-b.txt
February 27, 201115 yr No problem Joe. Hope you enjoyed the time out with your wife. I was actually out myself so I haven't done anything since this morning. I'm at a loss as to what to try next. I'm afraid to format the drive again in case there's a chance the data is still all on there. Unfortunately I don't have a spare drive big enough to cover this one. It's a 2TB drive that believe was around half full. I have a live version of Ubuntu. I wonder if I could start that up to at least see if there's anything on the drive? We go out dancing frequently. (Social Ballroom Dancing) I can do a file-system check, and also a pretty decent Waltz/Foxtrot/Tango/ChaCha/Bolero/Mambo/Salsa/Rumba/Hustle/Swing. You really need to just get unRAID to the point where there is a file-system recognized. If it does not recognize the reiserfs, ubuntu will not either. First, is there a proper file-system partition? What do you get when you type: fdisk -l -u /dev/sde If there is a single partition, you are half way there. If not, we need to fix that first. Next, try reiserfsck --check /dev/md3 If it says /dev/md3 cannot be opened it probably indicates the "md" device did not find the first partition on the drive. If it suggests it cannot find a reiserfs superblock, and a repair is needed, you need to follow its guidance. The correct series of prompts and responses is shown in this post: http://lime-technology.com/forum/index.php?topic=4021.msg35473#msg35473 Change the BIOS back to AHCI. You do not want the drive in IDE emulation mode. It is usually way slower. Joe L.

What do you get when you type: fdisk -l -u /dev/sde I get a bunch of information about sectors, blocks, etc, then the last line says "Partition 1 does not end on cylinder boundary."

I will go through those steps for the repair, but before I do, I was just curious...I changed the drives back to AHCI, and now the problem drive shows as unformatted again. So IDE = It shows as a recognized drive in the BIOS and "Missing" in unRAID, and AHCI = DOES NOT show as a recognized drive in the BIOS, and shows as "Unformatted" in unRAID. Is there anything to that? Really appreciate all your assistance with this today Joe.
February 27, 201115 yr I'm about to retire for the night. unRAID does not really care which you use. If you change the setting from AHCI to IDE you might need to use the devices page to re-assign the disk to its slot in the array. It will no longer then be missing.
February 28, 201115 yr Author Well...good news and bad news... The good news is the drive is back up and everything is "green". The bad news is, I lost pretty much all of the data on the drive. I have good and current backups of the essential files, but will have to re-rip some movie and tv show Blu-rays/DVDs unfortunately. I ended up doing a --rebuild-tree, and that brought the drive back up, and there is a bunch of stuff in the lost+found folder, but with the way it's laid out it's pretty useless. No original folder names and a lot of the file names are just numbers with no extensions. I may spend some time and go through some of the bigger sized ones to see what they are, but it's probably not worth it. I wish I could say I know or understand what happened. And I'm starting to realize this EARS drive isn't worth the trouble. Have had issues with it since day one. Perhaps I got a bad one (SMART doesn't think so). In any even, Joe I really appreciate all your help with this. Is it safe to say me clicking format is what did me in, or would I likely have been in the same boat regardless?

Clicking on format did not help. It might have been that the drive was just replaying journal entries. We've seen that take as long as 15 minutes after a non-clean shutdown. The files in lost and found as not as randomly named as you might think. Sub-directories usually have correct names. Joe L.
