I always use the PowerQuest PartitionMagic to modify my partition ,and my partition table gets some error,but always I still could get into the windows. Then some day I find a logical partition is lost! I recover my files by some software such as easyrecovery,finaldata and so on.

Could anyone tell me some tools to correct the partition table error??

Try ptedit.exe found on the second disk of your PM boot disks. It shows your partition table and you can edit if you see what needs correcting. But you should know what you are doing.

Sorry,I know just nothing about it.

I am looking for a good software which could correct it automatically.
