November 23, 201213 yr Sorry if this has been gone over to death, I tried to do some searching. Problem is that UnRaid works so good I only visit the forums about once a year when I need to add a drive, any way I need to ad another drive and I have a 3tb drive coming that I will use for parity and move the 2tb parity to data. I want to make sure what I have is compatable for 3tb, as from reading here some of the controllers are not coompatible. What I Have: BIOSTAR TA785G3HD AM3 AMD 785G HDMI Micro ATX AMD Motherboard SUPERMICRO AOC-SASLP-MV8 PCI-Express x4 CORSAIR CMPSU-400CX 400W ATX12V 5 - 1.5tb Drives 2 - 2tb Drives 1 - 2tb Parity I am on Unraid version 4.7, I have checked from time to time for a new version but see that it is still the current stable version. But it looks like I have to go to version 5 to use 3tb? Or can a format the 3tb as 2tb for now since it will be parity any way? I usually don't update untill a stable release comes out?
November 23, 201213 yr If you add the 3th on a 4.7 it will work but disk will only be used as 2tb. My advice would be to make a copy of your flashdrive info and then do an upgrade (that way you can always revert back), there are actually only very few cases where V5 is not rocksolid...

I may take your advise and try v5, I really don't need it to see 3tb right now because my largest data drive is 2tb, but I may try any way.

The ONLY solution on 4.7 is to add a host-protected-area and artificially make the drive look (and act) like a 2TB drive. The drive will then act as a 2TB drive, and report itself as a 2TB drive. You can use the "hdparm" command to add the HPA if your disk controller correctly reports the disk size. You can use hdparm -N /dev/sdX to see if it does. Once the HPA is added, the remaining 1TB will not be accessible in any way until you remove the HPA, but beware, that will cause unRAID to think it is a different disk, so you must go through the same steps as if upgrading to a larger size, and only after running 5.X... that supports a 3TB drive.
November 23, 201213 yr Author I think I will just do the version 5, sounds like less of a hassle. Is your preclear still working for the 3tb disk and version 5?
November 23, 201213 yr I think I will just do the version 5, sounds like less of a hassle. Is your preclear still working for the 3tb disk and version 5? As long as you use the most current version. Older versions will not work on 3TB drives properly. Current version as of this post is 1.13. Joe L.
