Alright, I'll try that out -- thanks.

If so, check its name and any warning messages. How big is the disk and does it have MBR format already? I have seen the installer get confused by disks that contain Windows raid artefacts or GPT format.
If the drive doesn't show up then check cables, power.
The disk is a terrabyte and no it doesn't have mbr format. I'll try out your troubleshooting if gparted doesn't work out. Thanks.
