Unless someone else pipes up to the contrary, it's my experience that you cannot do this (talk to 640M disks) under FreeBSD at all, at the moment. I have one (a M2513A), and FreeBSD 2.2.6+(May 11). I believe that 3.0-current can't do much better. The problem is that the 640M disks have sectors that are 2k bytes long, rather than the usual 512. FreeBSD does all file system and device calculations in terms of a global block size, which is 512 bytes. I believe that there are moves afoot to rectify this situation. Perhaps as part of the DEVFS change? In the mean-time, your best bet is to buy some of the 540M media: they have 512-byte sectors. I haven't tried them myself yet, but I know that the 230M disks work. It's all a bit disappointing, really. -- Andrew "The steady state of disks is full." -- Ken Thompson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
