Only SATA drives that operate under SATA framework and SATA HBA drivers
have this option available to them via format -e. That's because they
are treated and controlled by the system as scsi drives.
>From your e-mail it appears that you are talking about SATA drives
connected to legacy controllers, operating under old IDE framework and
using pci-ide/ata driver. For those drives, like for any ATA drives,
format -e does not provide read/write cache control.

can you answer this?
I've got a pretty dumb question regarding SATA and write cache. I
don't see options in 'format -e' on SATA drives for checking/setting
write cache.
I've seen the options for SCSI driver, but not SATA.
I'd like to help on the SATA write cache enable/disable problem, if I
can.
What am I missing?
Thanks!
