I have a WD 250GB SATA HDD, it shows up in the BIOS as a 250GB drive but when I partition it up it only shows up as a 130gb hd! I have Win XP Home SP2. Any Ideas?
To enable the rest (which will appear as a separate partition Right click My computer > Manage > Disk Management > Right click unpartitioned/unallocated space (black line) > Format. You'll want it to be NTFS file system.
you may not have HDDs over 137GB enalbed on your computer download WD diagnostics - it'll sort you out
