Corruption of Backup File Created by Mysqldump Command

WrittenBy:D J Barnes

Anyone who has used a computerhas experienced lost data. It may be due a failing hard drive, the infamous 'Blue Screen of Death' or because you haveaccidentally deleted a file youwere working on. Luckily, there is a solution toretrieve these lost files on all these occasions.

Retrieving aaccidentally deleted file is easier then you might think. When you deletea file, the data stored on the hard drive is not deleted. Only the reference to the file, stored at thedrives index table is deleted. This tablecontains the location of all the file fragments on the hard disk. Ifyour hard drive is not full and the data is not overwritten then you canuse any free or commercial 'uneraser' software to retrieve it. This software searches the hard drivefrom the first byte to the last byte for files,ignoring the index table.

If you lost your data due to a 'Blue ScreenOf Death', or power failure when a document was opened, it is a bitmore difficult. If you regularlyboot your computer, the data is lost. This is because the document was stored in the ram and in the page file. This file is an extension to the ram in order to increase the amount of data that can be saved.Booting from a live CD and reading the page file should give you fragments of your document back. The page file is located at 'C:/pagefile.sys' and will be cleared after each reboot.
