Hmm, you're spot on. Thanks for the link. Will update...though I did realize a hilarious little tidbit that was confusing the hell outta me, somehow along the way I started making temporary HPAs, lol. that p is rather important. UPDATE: BIOS is latest version, crash still happens with flash share on unstarted array, definitely strange network behaviour so I'm chalking it up to network chipset ATM. With only a single PCIe expansion slot adding an ethernet card is not an option, it's reserved for extra SATA. Not giving up quite yet. I'll stop posting about it in this thread though since it seems it's not 3TB related. Have plenty of things to try but it'll have to wait until tomorrow.

I did HPA from 3TB to 2.19TB, parity built fine, array was good to go by all appearances, had same crash that I reported. HPA all drives down to 2TB (was first thing I thought of doing), rebuilt parity, same crash. (Taking note of Joe's input now, there wasn't a power cycle between) Now I just precleared all drives just to rule out hardware issues since it's all new gear (Yes I should've done that first but I'm a noob here). All 4 precleared fine. Now that I've ruled that out I'm going to start over from scratch and report back. I also just started with a fresh unRAID install, so we'll see how things go from here. Back to 3TB, gonna power cycle, HPA to 2.19TB, power cycle, and get the ball rolling again. I'm not frustrated... not worried about anything right now, no data involved... I'm just learning how everything works. MB: Gigabyte E350N-USB3 HD: Hitachi 3TB 5400s x 4 See you guys in a day or two, not gonna start it right yet, got to go out right now.

Sorry, but that's a bullshit excuse for not having GPT support. If everyone thought that way there would be no progress. If >2TB was already in place we'd have a nice compatibility list going (assuming there isn't one already around here)

Hell yeah, good call on that one. Doing 4 now @ 100MB/sec.

I did just buy unRAID the other day. However, if I had known beforehand it didn't support 3TB drives I certainly would NOT have purchased. Just my 2c. I am still happy to support the project but 3TB support will soon become an issue with prospective buyers if it isn't added. TBH I never would've guessed that an OS released in 2011 wouldn't support >2TB. In the computer software world when you face such fundamental limitations and you still haven't overcome said limitations when the hardware is out in the wild, you've dropped the ball. I know that sounds harsh but it's the truth.

edit: This is on 5 Beta6a btw Experiencing much nastiness with this technique. Was having trouble at 2.2TB so brought them down under 2TB. Also followed advice on parity drive and it's now below 2TB. Thought I'd be smart and skip a future step there without really thinking it through. Anyways, parity builds fine, shares show up fine. Writing directly to disk shares murders the server in about 15 seconds flat... nasty crash. Attached is a picture of the terminal after crash, was unable to telnet in or retrieve syslog. Attached is syslog after reboot if that's any help. I would like to have unRAID write a new 4K aligned partition and reformat the drives, how can I do that? I have a SystemRescueCD (sysresccd.org) on flash I can also use if it's easier to use that. I know it seems like a silly question, but even after destroying the partitions and running initconfig unRAID thinks the disks are ready for use. Just messing around right now, I know this is all unsupported but if anyone has an idea or two I'd be happy to hear it. EDIT: NM, discovered the beautiful thing called preclear, giving it a shot. syslog.txt

For just torrents wouldn't something ARM based like a pogoplug suffice? A full fledged PC seems overkill.

Just did, and put parity back up to 3TB. All good so far.

Thanks for the tips guys, have 4 hitachi 3tb 5400s running. Parity drive is @ 3tb and building fine. Used sector count of 4280000000 for 2.19TB on the other 3. What's the appropriate way to reverse hdparm -N? I set the size back to normal value for the parity drive and it's back to 3TB, but wondering if there's a more proper way to set it back to default.

lol, just bought Plus license too. Is there no workaround?

Hmm...is this why I can't format my disks? Just built a box with 4 hitachi 5400 rpm 3TB drives, unRAID shows them as 3TB but won't format them.

Just setting up unRAID for the first time, have 4 brand new 3TB disks in, unable to format them. Version: unRAID 5.0 beta 6a Attached syslog. edit: Just saw the 3TB thread Definitely a little bit ticked off I bought the Plus license already, didn't even think to check for 3TB compatibility syslog.txt
