Yes. This same thing happen{s,ed} in sysinstall with memstick installs - and perhaps other SCSI over USB devices? - with some sticks and/or on some boxes; in particular after happily booting into sysinstall from a memstick, then not finding the same daX thereafter to install from. Bruce Cran added a message to the 'No disks found' dialog suggesting trying Options/Rescan Devices, which 'solved' the problem for that then quite commonly reported problem, for 8.1-R or so. Apparently the dialog message was only updated specifically for USB-based da devices .. cheers, Ian _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
