[t13] ATA Drive firmware update.

[Gana Pat]

Hi Folks,   I want to write a drive firmware update utility for ATA HDDs. (There are some rationale why I don't want to use Drive manufacturer's FW update util). What command is used to update the drive firmware in the ATA drives ? Is this standard across all the vendors ? Any hint in this area would be really helpful to me.   Thanks, Gana
