IIRC, it does require an _immediate_ format command right after the blocksize change, with nothing like an intervening bus reset etc. (or at least with only a very limited number of actions allowed between, like status inquiries). This defeats the idea to use the controller's BIOS in order to format the drive after the mode page change. Instead, use "camcontrol cmd daX -t 7200 -c '4 0 0 0 0 0'" right after changing the blocksize. I'm pretty sure i've done this before successfully (pre-CAM, using the old scsi(8) command). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
