如何mount dd出来的文件？

 

用fdisk来看每个分区的起始逻辑扇区号,扇区号乘以512就是所要的偏移值offset,
mount时用：mount xx.img -o loop,offset=offset xx/

如：

#fdisk -l -u -C 1  hda.img

Disk hda: 0 MB, 0 bytes
255 heads, 63 sectors/track, 1 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes

Device Boot      Start         End      Blocks   Id  System
  hda1            2048    13672447     6835200   27  Unknown
Partition 1 does not end on cylinder boundary.
  hda2   *    13672448   117208191    51767872    7  HPFS/NTFS
Partition 2 has different physical/logical endings:
     phys=(1023, 254, 63) logical=(7295, 222, 31)
 

可以看出有2个主分区,偏移分别是
hda1=2048*512=1048576
hda2=13672448*512=7000293376

因此mount命令分别是:
mount -o loop,offset=1048576 hda.img /mnt/hda1
mount -o loop,offset=7000293376 hda.img /mnt/hda2
