But... it boots up and goes "yuckola" when I try and use it. Our UFS is not yet up to the task. I've seen references to 1024-byte sectoring inside #ifdef PC98 though i'm afraid that they've simply special-cased this one as opposed to walking through every function and removing the implicit assumption that all the world's a DEV_BSIZE world. MO drives (which are hard-sectored) also suffer from this. > If anyone has any info on jumper settings or magic SCSI commands I can > use (after installing FreeBSD on another disk, natch) let me know... I'm afraid i can't offer you much more than scsiformat(8) for it... and i'm not even sure whether you gotta adjust some mode page parameters before to change the sector size (or whether it's even impossible at all -- this depends on the drive's firmware). I remember that i've once formatted an (otherwise almost dead) Maxtor MXT-1240S to something different than 512 bytes per block, just to test it. -- 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. ;-)
