OK I'm using this drive as my "learn how to use PC-3000" drive because it belongs to a friend and he doesn't really care if he gets the pictures on it back. If I can recover anything, it's a bonus.
So I copied the ROM from the USB board and wrote it to a compatible SATA board. I managed to get to to come ready and it would read from different heads for different amounts of time (at one time or another, I imaged data from all four heads). However, after a while of reading one head, it would start just getting ABR errors. and wouldn't read anymore. Now I can't get it to come DRD & DSC at all without ABR error.
I did initially make a backup of the modules when it was reading. Only one module (both copies) gave me a checksum error (6F). I don't know if this has any bearing on anything.
Like I said, I'm trying to learn my way around the utility and what everything does. What are some things you experienced folks might try with this drive before attempting a headswap?
Thanks, as always, for the help.
