SATA harddisk and the "hdparm" command

A very simple question:
Does the hdparm parameters take any effects on SATA harddisks?

Thanks very much for answering!

No, It behave same as on IDE.
You need to change the device name to run it,
for identification of primary IDE , i can run,
hdparm -i /dev/hda
for SCSI,
hdparm -i /dev/sda

All options are similar.

hdparm only supports a very limited subset of options for SCSI drives. Mostly the ones that identify the drive, or perform timing tests. None of the options for "tuning" the drive will work.

Thank you very much! But still one question ...

If hdparm cannot do any tuning on SATA harddisks, what will do the job?

Maybe sdparm.

Cheers.
