请教MOUNT的问题

jet.lee

SCO 506 ，我FORMAT一张软盘，成功，然后 # mount /dev/fd0 /mnt
随后报错 mount: cannot stat '/dev/fd0'

后来查看了老帖子，得知软盘要有文件系统才成，我就
# mkfs /dev/fd0 1440
mkfs: default type (HTFS) used
WARNING: attempting to create a 720K filesystem on the 1440K device
         /dev/fd0. The resulting filesystem will not take
         advantage of all the space on the device.

mkfs: Available blocks = 690
# mount /dev/fd0 /mnt
# cd

成功！可是我记得我以前FORMAT一张软盘后，直接就MOUNT了，没有问题，这次是为什么，不知道什么原理，请高手赐教这之间的关系！
