I installed a 1TB HGST drive in an 8+ year old dell inspiron laptop and it appears the bios has truncated the 1TB disk to ~80GB (same size as the original).

It appears that the drive has HPA enabled but it will not disable it or let me change the size. Any ideas.

Mmh, is the HPA feature set influenced by the security state, i.e. frozen security feature set?
A lot of laptops freeze the drives in the BIOS, which is a good thing (but useless).
Find out by if the drive is frozen by 'hdparm -I'.

I usually try to unfreeze it by sending the laptop to S3 ('echo mem > /sys/power/state') and waking it up again.

I do not have the laptop at the moment. It is for a friend/customer. I am doing the testing from an lga1366 motherboard.

Hmm. I switched my Intel SATA controller to IDE mode and the drive now says it is frozen

Have you tried sending a Secure Erase command (insert standard warning about deleting all data and firmware bugs bricking drive)?
 
I did try secure erase. That took the full time but did not change the capacity.


With that said this is solved.

HDAT2 was able to unlock it. The manual HPA removal mode failed multiple times however there was an auto mode that tried using less LBA48 (in auto it said using lba48 failed) I think it read lba16 and lba28 succeeded. After this auto remove hpa the drive is now at full capacity. I wish I had a screenshot in hdat2.

 Q6: Host Protected Area (HPA) vs. 28/48-bit LBA mode

A6: There is a problem of incompatibility on some hard drives (e.g. Seagate and/or in an external Maxtor One Touch) when you are using 48-bit command for removing Host Protected Area (HPA) created with 28-bit command.
48-bit command cannot remove HPA created with 28-bit command and vice-versa. Following solution is for disk supports 48-bit LBA mode only and if you have HPA greater than 127 GB.

Notice:

"Some vendor-specific external drive enclosures (Maxtor) are known to use HPA to limit the capacity of unknown replacement hard drives installed into the enclosure. When this occurs, the drive may appear to be limited in size (e.g. 128 GB). In this case, one must use software utilities that use READ NATIVE MAX ADDRESS and SET MAX ADDRESS to change the drive's reported size back to its native size."

Solution:

1. Power-on PC, boot and start HDAT2.
2. In 'SET MAX (HPA) Menu' select 'Set Max Address'. Change 'LBA mode' from 48 to 28-bit LBA mode and press 'S' key to set maximal address for 28-bit LBA mode (127 GB).
3. Power-off PC (Important !), power-on PC, boot and start HDAT2.
4. In 'SET MAX (HPA) Menu' select 'Set Max Address'. Leave the selected 48-bit 'LBA mode' (or change 'LBA mode' from 28 to 48-bit LBA mode) and then press 'S' key to set maximal address for 48-bit LBA mode.
5. After restart you should get the full (native) capacity of hard drive.

BTW, Thanks guys for helping. It was quite frustrating to have a $70 drive that I bought for a customer end up being worthless.

Is there any chance of stopping the dell bios from creating this hpa so I could actually use the drive in the laptop or is this hopeless.
