Once you've added a 3TB drive you your array, there is no going back. Drives > 2.2TB are not recognized. Joe L. Understood. I plan to wait a couple of weeks and make sure everything works before adding the 3TB drive. Thanks everyone for the quick responses. The community here is amazing!

Hello all, I'm going to upgrade from 4.7 to 5.0-rc3 this week. I'm running out of space and I'd like to start adding 3TB disks to the array. Hope it won't come to it but if I have problems I want to confirm that it's possible to fall back to 4.7 before taking the leap. Any pointers / gotchas I should be aware of when going back to 4.7? Sorry to bug the community but the process of downgrading to 4.7 isn't documented in any "official" docs from Limetech and while there are some forum posts I'm not sure whether they apply to the latest 5.0 releases. Thanks

Every time I run a parity check I get about 10-15 errors just like the one below.

I was trying to do that earlier today. I gave up and ended up moving the drives to another computer. The firmware update ISO from Seagate uses BCDW as the bootloader which doesn't support booting from flash according to this post: http://www.911cd.net/forums//index.php?showtopic=20681

Does anyone have one of the original 3-in-3 drive cages that comes with the Antec 1200 that they are willing to sell? The case comes with three of them and has space for four. Also -- Has anyone successfully disabled the blue LEDs on the 120mm fans?

Thanks dgaschk & Rajahal. I'll order the splitters linked above and let you know how it goes.

I'm building a new server for unRAID and ran into an unexpected glitch. I'd appreciate any guidance the community can provide. Apologies for the long post but I wanted to provide as much detail as possible. I'm using the components specified in the wiki for the 12 drive budget box with one exception. I'm using an Antec 1200 case instead of the Coolermaster 590. I also bought the Corsair 430W (CMPSU-430CX) power supply recommended by the wiki. What I didn't realize until AFTER everything was delivered is that the power supply only has 4 SATA power plugs and that I'd need 12 of them. I neglected to consider that the CM590 cages use one power plug and distribute power to the drives within while the Antec 1200 cages do not distribute power so each drive needs to be powered individually. I'm looking for the most cost-effective solution. Drives cages would bust my budget and I haven't found any reasonably priced power supplies with 12 SATA power ports. I found this 3 way SATA power splitter which looks ideal for my situation: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10226&cs_id=1022604&p_id=5184&seq=1&format=2 This one also looks promising but it isn't ideal since the molex ports don't provide 3.3V power which some drives need (according the product page on monoprice): http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10226&cs_id=1022604&p_id=5188&seq=1&format=2 I'm concerned that the splitters may reduce the quality of power delivered to the drives thereby causing less stable operation. I'm also concerned that using one 3-way splitter on each of the 4 SATA plugs may overload the wiring to the power supply by drawing power for triple the intended number of drives. Has anyone used splitters to the extent that I'm planning? I'd appreciate any tips / pointers. Thanks
