One day, a friend called to say, he used Fdisk to the hard disk repartition, encountered a very strange thing, that is, the original expansion of the partition can not be deleted (friends with the brand machine)! Is that something like this?

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; came to friends home, I started the computer with floppy disk, into Fdisk, found that the capacity of the hard disk 40GB, The extended partition takes up 25GB, and there is no logical disk (which he deleted earlier). It then goes to the "delete partition Or longical dos drive--delete Extended DOS Partition" menu, deletes the extended partition, but prompts "cant delete Extended dos Partitionwhile logical drives Exist "(you cannot delete an extended partition when a logical disk exists), gee, what's going on? There is no logical disk! To reconfirm, I went to the "delete partition Or longical dos drive--delete Logical dos Drive (s) in the Extended DOS Partition" menu to delete the logical disk, It prompts "No logical drives tabbed" (no logical disk defined).

That's weird, why is Fdisk contradicting itself? What did the brand computer do to protect the hard drive? Think of this, my brain suddenly a bright, many computer manufacturers in order to alleviate the distress of customer reload system, the system installed after the backup, put into a special partition, not the brand computer also has a special storage backup system partition, and is hidden up? Because Fdisk itself can not see whether the partition is hidden, but with the help of Pqmagic tool software, into the pqmagic to see the hard drive, sure enough, a partition is hidden, click to cancel the hidden exit pqmagic. When you enter Fdisk again, a logical disk is found, entering the "Delete partition Or longical dos drive--delete Logical dos Drive (s) in the Extended DOS Partition" menu, remove the Logical disk. Also entered the "delete partition Or longical dos drive--delete Extended DOS Partition" menu, the extended partition was finally successfully deleted.
