Hello

I'm now far away from Data recovery and HDD repair buisiness (and never was a real Guru), but my coworker asked me to help him with his Hitachi HDD.

Does mhdd have limitations with LBA addressing? The problem is, that with "configure" command i cannot restore original capacity of 3Tb Hitachi drive. All that i was able to achieve is about 800Gb.

If mhdd have that limitation (i understand, because mhdd is old for now and unsupported) then, which freeware tool can help me ?

I was unable to find correct Vendors utilites. Those utilites, which i tryed to use, are useless with that problem.

The history of that drive:
The first wrong thing, that was done with "patient", is, it was "adjusted" with external usb box, and then it was "processed" with HP server raid controller. Then it was installed on CCTV recorder box.
And then it appeared in my hands, it had limitation of maximum lba address, not hpa, and as result it's size was 128Gb.
I think his size was redused with old controllers firmware, which not expected such a big LBA maximum number. Some kind of the glitch.

Thank you.

Hmm, it seems Victoria can do that. I tried to use her already and simply missed the command that i needed.
I simply prefer to use MHDD.

If i'm right, then it's RDC command. I'll try it tommorow.

PS: spent more time for posting messages to the forum, and just more deeper "googling" seems solved that problem.
Well, it's as usual.

HDAT2, Hitachi's Feature Tool, and HDD Capacity Restore Tool are other tools that you might like to try. They should correct the 128GB problem (28-bit LBA limit), but won't fix the "800GB" problem. The first appears to be an HPA issue, whereas the second problem looks more like a 32-bit LBA limit that is present in early BIOS-es or in SATA drivers.

Thank you for replying.

Today i gave drive back to it's owner, and told him, what to try to do to restore HDD's size back. (He is also computer tech)

Will see, help it or not.

i think HDAT2 can help you to restore capacity.
