Re-setting full drive size

[NickS]

For Seagate Disk Wizard:

Here is the
procedure for checking or setting the reported drive size:
o Load DiscWizard Starter Edition
o Select "Utilities"
o Select "Set Hard Drive Size"
o Select the correct drive ( if more than one drive installed)
o If the "Current Maximum LBA/CYL" is not equal to the "Native Maximum
LBA/CYL" values, change it to the value in the Native Maximum LBA/CYL
number.
This should force the drive to report the correct size to the BIOS.

If you are still unable to read the full capacity of the drive, use
DiscWizard Starter Edition to run a Zero Fill on the drive. This will
write through the MBR with zero's to remove any remnants of the DDO.

For Seagate SeaTools for DOS, select menu option C "Set Capacity".

Set Capacity
Occasionally, a disc drive may be too large and its size needs
to be reduced to a lower capacity. Similarly, a drive with a
reduced capacity may need to be reset to its native maximum
capacity. Three choices are available under this section:
S - Set 32GB Capacity. A common setting for older systems.
R - Reset to Drive Maximum. Full capacity is restored.
M - Set Manually. Allow you to set a specific size.

For Samsung:
http://www.samsung.com/Products/HardDiskDrive/utilities/hutil.htm is the download and instruction page for hutil
Use Tool->Set Max Address->Recover Native Size
Note: this option appears in version 1.08 but not in version 1.13. If this option (which is shown in the instructions) does not appear in the current version, contact Samsung.
If you are still unable to read the full capacity of the drive,
use Tool->Erase HDD->Erase The Entire Area
Note: USE WITH CAUTION - one user reports that the utility somehow set the "native size" to a low value.
