This is how a USB cdrom appears to FreeBSD - as a SCSI device. No problem there. > and /dev/da0s1 (the normal > USB disc drive device).

This is read only - you will be able to read from the disc, but not write to it. In order to be able to write to this disc, install sysutils/fusefs-ntfs and use the ntfs-3g command to mount your disk. If you are not going to use the disc to transfer data between Windows and FreeBSD, I would advise you to repartition the disk and create an NTFS partition for your windows data and a FreeBSD partition in UFS format. Just backup any data, and use windows disk management to create an appropriately sized NTFS partition, leaving the rest of the disk unallocated. Then use fdisk and bsdlabel (or sysinstall) in FreeBSD to create a slice and partition for FreeBSD. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
