For the Seagates and Western Digitals, it is pretty easy to find the methods. If the Fujitsu drives like mine were easy to find vendor commands for (Or even a firmware image to figure out my MHZ2xxxBH G1 Rev 9), then all the BEV-designation Western Digital drives on eBay wouldn’t be so popular with Xbox 360 owners! The related MHx families that I’ve looked at the firmware dumps of seem like a good place to start – if I had a few spares to test experiments on. Hehe, not trying random 0x80-0x8F or similar ranges to find vendor commands without understanding the microcontroller on them.
I have yet to find anything about the Hitachi models, but I haven’t exactly spent a lot of time on non-Fujitsu/Toshiba drives and I knew about the Seagates from 2010 when all those people had to reset the firmware… I was curious and discovered the wonderful world of EIA232-to-Seagate adapters and terminal commands.
So, here’s the rundown:
Fujitsu=No chance – even programs like HDDErase don’t work on the most recent families. Try it anyways for designations upto MHG or so.
Seagates=Use serial terminal
Western Digital=Use this topic’s script
Toshiba=???? (Don’t have any recent ones to test – biggest I have is 6GB I think)
Others=???? Just buy PC3000 UDMA.
