Hi, I bought a new internal hard drive (4TB). When I want to format it so it becomes only 1.63TB in windows7. With Mac OS it is 1.81TB. I have tried to solve it through DiskManager i Mac OS so with no success. What do i do wrong.
(Tried to partition the disk with one block - same result).
The disk is new and was initialized as GPT, but even so shows up as 1678GB
I set up an identical drive 2 weeks ago at 4TB
The only difference is the system they were initialized on. The drive that was set up 2 weeks ago was on Win 8 in an external USB bay. The new drive was initialized on server 2012 on SATA.
More oddness:
A) Even inside the DISKPART utility, and after moving the new drive to the external USB bay on the WIn 8 system, it shows up at 1678GB. I also did a CLEAN on it and no change.
B) The drive that was successfully formatted to 4TB shows up at 1.64TB in the disk manager on Server 2012, even though it contains a 3.64TB partition.
If a disc utility such as HD Sentinel or CrystalDiskInfo is reporting a capacity of 4TB, then the problem could be a 32-bit LBA limitation in your SATA driver.
I experienced this too, and when I used the WD diagnostic tool it reported bad blocks which it couldn’t repair so I RMAd it straight away. The other 4TB black I got at the same timeseems to be operating fine. Perhaps it is a hardware/firmware issue?
