Off the top of my head, the following is the list of existing or soon to appear devices that could use this (taken from our thread last year, at http://kerneltrap.org/mailarchive/linux-fsdevel/2007/3/11/317183): (1) R/W optical drives (2) S390 dasd devices have a 4096 byte sector (3) new 4096 byte disks (which intend to export a virtual 512 byte sector) Anything else pop into mind? Any idea if SSD or FLASH devices have thoughts to use a non-512 byte sector size? What tools are most critical to support? Thanks! Ric
