cant format 3tb disk.. need help

[Morgoth]

hi got 2 3tb toshiba pc p300 3tb had disk
problem is i cant get them back to work properly..
1 only sees as 2tb in windows
other one he sees it as 3tb drive (2700gb aprox)
i have them both connected to the sas controler sees them both as 2tb hard disk
i cant format the one it says to be 3tb under windows
but i cant make the other one bigger.. is my sas controller faulty?
they both used to be a raid 1 but some how that all got fucked up.. now im tryng to fix it

use command prompt (admin)

use the disk part command to wipe the partition tables off the drives.


like so.

> diskpart

List disk

sel disk #

clean

in that order. Then open disk management (this is easier than doing it via cmd)

make sure the drive is initilized as GPT (mbr has 2TB limit)

it could also be the sas controller. some only support certain size limits, but if one shows correctly im willing to bet its the init type.
