kkthxbye said:I used hdparm -S251 hdb - also tried a lot of the other commands (-K). Got an error that said somthing about feature not implemented.
The -S251 was used on the passport drives because -S0 wouldn't work. But yeah, if -S251 gives an error, I doubt -S0 will work. Did you try -B255 to turn off APM? That might work for you.
Actually, do ANY commands work? Does -g give you the drive info?
