I'm with Darrin. Makes sense to me.

Gary,
If the HDD supports the 48-bit feature set, regardless of the capacity, it should set the bit. At least this is how I/we interpreted the feature set.
Recall that there are 2 "sub" features that the 48-bit feature set address:
1. Ability to access >137GB
2. Ability to transfer >256 sectors per command
How might this impact the operation of the SET MAX and SET MAX EXT commands?

Question to all the drive folks.......
There seems to be a fuzzy area about use of the 48-bit addressing supported bit in the IDENTIFY DATA (bit 10 of WORD 83). I guess some are setting this bit regardless of the drive capacity and some are only setting it if the capacity is over 137GB. I am hearing "rumors" that this might be creating some driver issues because of the SET MAX and SET MAX EXT commands.
Just wondering how you drive folks are setting this?
