Only 801.6GB showing out of 3TB (Seagate 7200.14 ST3000DM001

[ryansoh3]

Hi all,

I just noticed that my Seagate 7200.14 3TB drive was only showing 801.6 gB (746.5 GB) out of the entire 3 TB.

Thankfully, I had a RAID 1 setup and my data's safe, so I formatted this drive and it still showed 800 or so GB.

A quick error scan in HD tune showed 100% health, except it only could scan the 800 GB portion of it.

Any ideas what might have happened? Thanks!

Here's some info:

Most probably your BIOS needs to be updated.

It was working fine the past two months... thanks for your reply though!

Ah, I think the problem was to the RAID array.

Moved the HD to another SATA port and it showed the full 3TB. Thanks for your help guys!

Check the sector size on the SATA port then check it again on the RAID port.

It is probably as Northwind suggests and a problem with BIOS but for RAID card.

4KB sector formatting, try it on a Visat/Win 7 64bit system and it should see the entire 3TB.
