Situation: I hung up a 10 gb of disk/dev/VDB on Linux, a single sector size of 512, points inside a zone/dev/vdb1, vdb1 start sector number is 2048, corruption,
Then I through the dd to/dev/vdb1 seek=2048 bs=1 b the location of the count=1 write 512 characters a,
Next I through dd/dev/VDB skip=4096 bs=1 b count=1, the location of the reading data is read out is not the characters a, why???
