I've got such a drive and a problem with it... I've run HUTIL with jumper on 32GB Clip and from this time drive is limeted to 32GB (I think so, but I'm unsure - I've got this drive from a friend of mine, who couldn't format it /drive not ready error/ or use it /corrupted FAT/), no matter if the jumper is there or not, HPA option is not available in HUTIL for thist drive, MHDD 4.4 does not indicate HPA bit set... I may set HPA in MHDD and it works just fine, I may remove it later, but it restores capacity of 32GB (LBA 66055248) instead of 80GB (LBA 156368016) - to be accurate that's 76GB.
That's surely not a problem of computer's BIOS, because I have a second identical drive and it works just fine.

There's also a trick with this jumpers - on the plastic cover of connector there are marks - MA, SL, CS, but on the label there are different marks, due to which SL position is in fact a 32GB Clip and Slave is w/o jumper at all, rest two positions are same.

Me stupid how could I not look at the FAQ
You're great Dmitry, thanks a lot for your help and patience.

So did that helped?

Yes it did help, thanks a lot for your help again.

I've got one more question to you - I've also got a Samsung SV0432D, it works just fine, but it always indicates HPA bit set in MHDD and it cannot be turned off... theoratically this drive has disabled one head... maybe this is it, but I just wanna know your opinion about that.
