Data really deleted???

18 05 2008

Today I moved my data using the robocopy.exe tool and using the /move switch; the tool migrated data from one usb disk to another one. Before returning my usb disk to the IT department I checked the disk partition with one of the tools I use to check deleted files. Guess what the tool found 18000 files in 10 minutes scan on the usb volume which was empty…

Before I will return this USB disk for re-use I will make sure no data is left which can be recovered by any tool. With physical disks I used gdisk with dod option to wipe all data. For the USB disk I am going to install tool called Eraser which is freeware.

How to safely clean a harrdisk before disposal?

Go to http://www.heidi.ie/eraser/download.php and download the Eraser tool.

After the erase process has finished I re-run my “Recover My Files” tool and now it was only being able to read rubbish written by the Eraser tool.

We all should be aware if you delete a file in Windows and clean up the Recycle-Bin that files are not deleted from the physical disk. Only file reference information is removed from file allocation table and easy recoverable with small tools. Was this post useful for you? Please support me below by checking out the ads.
