Re-reading the partition table ...
BLKRRPART: 设备或资源忙
The command to re-read the partition table failed
Reboot your system now, before using mkfs
If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk( 8 ). )
为什么总是:设备或资源忙 看来是没有成功
你看这一句:/dev/hda1 1 770 6184993+ 1b Hidden W95 FAT32 //(为什么是隐藏的)
