Yes, but hex format or printing CHS and LBA request would save some amount of time. >> By the way, may be it would be a nice idea to warn users that they have >> ATA_FLAG_54_58 bit off, and device will work in LBA mode not >> in CHS as was before? > > Users wont notice at all, from users perspective the disk is just a > bunch of sectors, > the interface method used to talk to the disk is nowhere to be seen...
