Test on a junk media card just in case I'm totally off base.
After some experiments in FreeBSD 4.9, I found out that just running the fdisk on da(4) device will enable to mount partitions on it: $ fdisk /dev/da0 ******* Working on device /dev/da0 ******* parameters extracted from in-core disklabel are: cylinders=495 heads=2 sectors/track=16 (32 blks/cyl) parameters to be used for BIOS calculations are: cylinders=495 heads=2 sectors/track=16 (32 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: sysid 1,(Primary DOS with 12 bit FAT) start 25, size 15783 (7 Meg), flag 80 (active) beg: cyl 0/ head 1/ sector 10; end: cyl 493/ head 1/ sector 16 The data for partition 2 is: <UNUSED> The data for partition 3 is: <UNUSED> The data for partition 4 is: <UNUSED> $ mount /dev/da0s1 <<Success>> This should be automatically done by the system, I suppose. -- Alexander Pohoyda <[EMAIL PROTECTED]> PGP Key fingerprint: 7F C9 CC 5A 75 CD 89 72 15 54 5F 62 20 23 C6 44 _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
