That might be a good hunch, but the SD card itself just says "2.0 GB" on the outside - no mention there or when I purchased it to have any Mac-ness. I don't recall seeing anything Mac-ish when I ran the fdisk(8) command as % fdisk da1 The output then seemed to correctly reflect that partition (slice) one (1) was 960 MB in size. I tried later (once the system had recovered and the fsck(8) had finished) to use fdisk(8) to put 1920 MB into slice one. But that didn't seem to work. I marked all the other three slices as "UNUSED". Is there any trick to using fdisk(8) that is hidden in the man page which I evidently missed? I used the "-i" flag and it led me by the had through each slice - I thought I did the "right" thing, but I was never able to mount(8) the SD card after that, even though dmesg(8) reported "da1" as being there. I kept getting "invalid parameter" or the like when I tried mounting as I am used to: # mount_msdosfs -l /dev/da1s1 /mnt I also tried: # mount_msdosfs -l /dev/da1 /mnt But both versions failed. Finally, in desperation, I formatted the SD card on a Windows XP laptop. Windows put it back into FAT shape (using the low level - not the "quick" - format there) and gave it 960 MB, sigh... :-( Regards, web... -- William Bulley Email: w...@umich.edu _______________________________________________ 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"
