關於RAM Disk

macarthor

[root@localhost ~]# dd if=/root/test.img of=/dev/ram0 bs=512 count=2880
[root@localhost ~]# mount -t msdos /dev/ram0 /mnt/vf
mount: /dev/ram0: can't read superblock
[root@localhost ~]# dmesg
FAT: logical sector size too small for device (logical sector size = 512)

/root/test.img是軟盤鏡像，文件系統是FAT12，其sector size為512 byte

這個錯誤應該是/dev/ram0的sector size與msdos(fat12)的sector size不一樣造成的

那麽，應該如何修改/dev/ram0的sector size呢？
