You just have to | set the right blocksize, I could provide you with a function for | that, no more ioctl mess ;) That would be _greatly_ appreciated! The question is, would this be 'portable' to other drivers? In other words, how much trouble would it cost me to get AudioFS to work with SCSI? (On a side note, I'll be getting a SCSI card and accompanying Plextor CDROM from a friend of mine soon, so I can work at getting AudioFS to work on SCSI CDROMs).
