Whereabouts is the physical sector size of a device with long physical sectors defined? I note that long logical sectors or multiple physical sectors per logical sector are defined in the IDENTIFY DEVICE block. However, I see no such mention of the physical sector size.
Could anyone enlighten me? Or is this an omission from the specification?
The xEC Identify data tells us bytes per lba and lba's per drq, yes?
What other byte count do we need to write/ read via ATA?
Also, does anyone know of a drive which uses the long logical sectors feature set?
Anyone?
People have mentioned SCSI drives which use these - have any of you drive engineers out there built one which is publically available???
DVD commonly store 32 KiB per write, CD commonly store 64 KiB per write.
DVD-RAM write without exotic preparation.
> physical ... > logical ...
What those words means varies radically by context.
