| | [SOLVED] How to format a USB drive safely? Hi, I searched in many web pages and I learned that secure formatting (DoD, NSA, Gutman, etc...) doesn't works with USB drives. Is it true? So, how can I secure delete a USB drive preventing a recovery data? What software I need? Last edited by seventrad; 06-03-2011 at 09:42 PM.. Reason: Solved |

| | The correct way I searched in web and I found the correct way: 1º) Install Eraser 6 or above: Link: Eraser :: Downloads 2º) VERY IMPORTANT STEP: Delete all data in USB device with DELETE key or FORMAT it with the Windows Explorer! The USB device need to be completely empty. 3º) Run Eraser 6 as Administrator (very important for Windows Vista/7 users). Right-click mouse and choose "Run as administrator".  4º) Choose the options below: 1 - Create a "New Task"  2 - Choose "Run immediately" and click in "Add Data"  3 - Choose the "Erasure Method" (the correct option is "Pseudorandom Data 1 Pass" - only 1 pass. For more detail see reference (*)) and check "Unused disk space", then select the USB drive. Check "Erase cluster tips".  4 - Click "Ok" and the erase will be run immediately!  5 - During the task, all unused bytes in USB device will be overwritten by random data! Only 1 pass is necessary (*).  (*) Reference: Heidi Computers Ltd Support - View topic - Erasing USB key Drives (for understand I recommend the read all topics) Last edited by seventrad; 06-03-2011 at 10:57 PM.. |

| | CCleaner also has the option of a secure wipe of a drive. You can choose only free space or wipe the entire drive. Did Eraser6 wipe the entire drive or only free space? Your snip shows only unused space being overwritten. |

| | In CCLeaner Options/settings where do you have the overwrite settings? It has the options od 1,3,7, or 35 passes. for A USB flash drive, 1 pass should be enough.  |

| | How long did CCleaner take in actuality? Many program give an estimate which is high then completes in a much shorter time. I trust CCleaner to do a good job, if a program says it wipes and takes a few seconds, not so trustworthy. A wipe is CPU-intensive too and will be slower with other programs running at the same time. |
