HDD GURU FORUMS

Hi.
With MHDD I am using a 4TB disk with LBA 7,814,037,168.
The problem is that when doing ERASE the final sector 3,519,069,871 appears (slightly less than half).
I have tried /DISABLEBIOS when starting MHDD, it goes into PIO mode but the final sector remains the same.
Why the limit this one?

Have you tried this on a different motherboard with a different chipset? Could be some sort of limit on the hardware that's affecting the software.

There appears to be a 32-bit LBA limit.

7,814,037,168 - 2^32 = 3519069872

Nice! Makes perfect sense.

So it means MHDD limitation or motherboard / system limitation?
