I have a Samsung Spinpoint M9T ST1500LM006, it is a SATA III (6gb/s) drive. I want to limit it to SATA I, what software lets me do this?

I don't think there's a software for that.
If I remember well, there were a few drives with the possibility of limit it with a jumper. But on these new drives, I don't think that's possible anymore.

The set max udma mode setting in MHDD can't do it?

The drive has no jumper settings, but the drive is downward compatible with SATA II and SATA I which means there must be someway to force it into either mode.

what you want to achieve by limiting the transfer rate ?

Original Playstation 3 models have trouble with SATA II and SATA III where the system will not boot properly sometimes. It's necessary that I force the drive in SATA I so I'm not gambling whether or not my console will start properly.

I would bet that doing this will set some "FLAG" most likely on the FIPS section of ROM so that the MCU knows at boot up what set of SATA speeds the drive should report to be able to use ...

Sounds reasonable ....

Ok !

I've done some testing with the PAID LICENSED version of SHT and IT DOES WORK and IT DOES SURVIVE THE POWER OFF/ON :


Can you share this software, or do you know of any software that's very similar? I have no idea where to find SHT, I only speak English so it's hard to sift through these sites.

At any rate this experience shows that it's possible to set SATA speeds on ROM on SAMSUNG drives.

It seems that you are working out the function of the FIPS one byte at a time. :-)

Off topic: I wonder what the drive is trying to write to the FIPS when it gets corrupted?

ISTR that Ace's blog article stated that all one needed to do to repair a damaged FIPS was to write the FIPS header, fill the module with zeros and then write a valid checksum at the end. I could be wrong, though.
