I got the same "no space errors" updating 3 plugins (Statistics, Streams, & System info). All updated to new versions and I can see it wrote to the USB just fine.

TOSHIBA MD04ACA500_xxxxx (sdb) 4883770532 * 5 TB Linux 3.9.11p-unRAID. root@Tower:~# hdparm -N /dev/sdb /dev/sdb: max sectors = 9767541168/9767541168, HPA is disabled

I am thinking it actually was "HPA?" on the other box I precleared it on and I was just looking at the wrong view. I will go with your Plan A suggestion... if I run across a 5TB that is larger, it becomes the parity drive I have both boxes churning right now (tower2 preclearing tower1's old parity to be new data drive and tower1 rebuilding parity on 5TB). Hate to disturb them when they are working lol

shows as 4,883,770,532 in detail view

now it shows "HPA?" in Tower1 MyMain while Rebuilding Parity. Is this going to be a problem? Odd it did not show in Tower2 (where it was precleared).

Preclear Successful ... Total time 40:05:21 ... Pre-Read time 9:09:02 (151 MB/s) ... Zeroing time 8:11:57 (169 MB/s) ... Post-Read time 22:43:19 (61 MB/s) Now installed in Tower1 as new parity drive Parity-Sync in progress. Total size: 5 TB Current position: 42.5 MB (0 %) Estimated speed: 42.5 MB/sec Estimated finish: 1 day, 8 hours, 37 minutes

don't see anything as you mention.

size = 4,883,770,552 Pre-Read. 48% @ 175 MB/s (3:51:07) I don't see anything mentioning HPA. Where would that be located?

tried it just now Pre-Read. 27% @ 181 MB/s (2:04:02) I use a KVM with a 21" monitor for the two servers so I have it up on the screen now too.

hmmm... that is what laptop could see through usb2 connection. Drive is preclearing now in unRaid and shows full 5TB. (deleted image to avoid confusion)

5TB arrived a day early. Removing the case is definably a one-way proposition (no screws, uses locking tabs). Not going to be able to send it back now. I believe these are re-branded Hitachi drives. model: MD04ACA500, Mfg data 2/27/14, firmware A0. Preclear on a 2TB takes about 22 hrs so this one will be couple days PS. instructions on ruining the case http://goughlui.com/?p=4688 PSS. No hidden partitions (at least Windows 7 can't see any). Just warranty PDF and autorun to install backup software.

Both boxes have a single AOC-SASLP-MV8 in them. I see some threads here that they appear to work with 3 & 4 TB.

I presume you've already upgraded to v5 (or 6) ... but a more compelling question (given that you've currently got all 2TB drives) is whether or not you've confirmed that the system supports > 2TB drives ... Both boxes are running v5.x. I can't find a definitive yes (or no) on either motherboard as to any limits on HDD size. Asus M4a785-M (older tower) Biostar A880GZ (new box)

Maybe. But you will be the first person using a 5T drive. Depending on the size it may need a myMain config change even if the is no HPA. Let me know when you get it and I can direct you. It will be placed as parity drive on a full 26 TB server (all 2 TB drives). Then I can start replacing those drives with larger and adding the 2 TBs to Tower2

thanks for the heads up. Have Toshiba 5TB arriving soon and it likely has hidden crap.

Replaced (3x) COOLER MASTER STB-3T4-E3-GP 4-in-3 with (3x) these new iStarUSA BPU-350SATA-RED 5-in-3 cages. Added two more 2TB drives for a total of 12. The remaining 3 slots are empty but connected to SAS card; just add drives! Almost all positive feedback for these except for now my cabling is all a mess (lol). Glad I procrastinated long enough for these to come to market

Thanks for the compliments. You are one of the giants on whose shoulders I stand.

It connects to any USB 2.0 header on the motherboard. Just converts it to 2 USB inputs same as if you used wires to an external bracket. Should work with any motherboard. Just make sure you have clearance for the USB key once it's installed.

"We stand on the shoulders of giants." US Budget build using Asus M4A785-M. USB header adapter is the Koutech USB 2.0 Header-Pin to Dual Type-A adapter Model IO-UU220. I blocked the side air vents with a standard manila envelope containing a printout of the drive serial numbers and port assignments. All jumpered EARS except 4 & 5 which are left over WD EADS 1TB from the Hammer NAS this replaces. Next door is my Dell T105 running W2K8 (office file server). Direct access to either via KVM.
