購入した 生のものの場合、 まあ vfat に なっていると考えられます。 ”/var/log/syslog”に 表示されるのは
# cat syslog

御覧の 様に sda1 です。
# mount /dev/sda /mnt/
mount: you must specify the filesystem type
# mount -t vfat /dev/sda /mnt/
mount: wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systems
# mount -t msdos /dev/sda /mnt/
mount: wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systems
mount は sda の場合 何故か 出来ません（当り前かもしれません）
fdisk を 試みましょう。/dev/sda の場合です。
# fdisk /dev/sda
Command (m for help): p
Disk /dev/sda: 247 heads, 62 sectors, 1020 cylinders
Units = cylinders of 15314 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 1021 7807040 c Win95 FAT32 (LBA)
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(1, 0, 1) logical=(0, 130, 5)
Partition 1 has different physical/logical endings:
phys=(912, 63, 0) logical=(1020, 30, 4)
Partition 1 does not end on cylinder boundary:
phys=(912, 63, 0) should be (912, 246, 62)
Command (m for help): q
/dev/sda1 という事になっていま す。 ちなみに sda1 で mount ば 問題は 無いという事です。
# mount /dev/sda1 /mnt/ # df | sed 2,3d Filesystem 1k-blocks Used Available Use% Mounted on /dev/sda1 7802896 7872 7795024 1% /mnt # umount /mnt/
まあ そういう事だ と考えておきましょう。
fdisk を 試みましょう。今回は /dev/sda1 の場合です。
# fdisk /dev/sda1

mac-fdisk した後のものを見てみましょう。
さて mac-fdisk で パーテションを作成した後のものの場合
# cat syslog Nov 19 21:38:00 sv kernel: usb.c: USB device 3 (vend/prod 0x718/0x672) is not claimed by any active driver.

今回は sda1 というのは 明白に 出てきません。”unknown partition table”
# fdisk /dev/sda Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable. Command (m for help): p Disk /dev/sda: 247 heads, 62 sectors, 1020 cylinders Units = cylinders of 15314 * 512 bytes Device Boot Start End Blocks Id System Command (m for help): q
まあ こういう事のようです。
# fdisk /dev/sda1 Unable to open /dev/sda1
fdisk は /dev/sda に 対して 行うのでしょう
にゃんたろう 拝！
