Eraser

Use Eraser and have it wipe the whole drive (blank space). You cannot securely delete individual files from a USB flash drive due to their wear leveling algorithms (writes that would go to the same place on a hard drive to alternatively set 1s and 0s go all over the drive with flash). In theory, wiping the whole drive should work, though.

Incidentally, I've got a test setup of a portable version of it.

Sometimes, the impossible can become possible, if you're awesome!

Eraser Portable Test Version

Is your test setup using Eraser 5.7 or 5.8? Is it available for test/download?

Not yet

... but soon. It's portable and about a meg and a half. Was going to try to prevent the Explorer integration tick-box from affecting it, but I'd have to modify code. So, I'll probably post a beta soon.

usage of sdelete

Hi,

When will your beta of portable eraser available?

I am using sdelete which is a commandline wipe from sysinternal
I wrote a batch file so that any folder or file that is dragged over will be "directed" to sdelete.exe to do recursive wiping.

The issue was that the directory entries are still valid for NTFS and FAT16 systems when i do file recovery.

Does your portable eraser clean up directories entries?

Would love to do some test on it when it comes available

Nope

That just resets the file system. All your data is still there and can be undeleted.

Hi, it could be a sugestion

Hi, it could be a sugestion to reformat the drive in a non os generic file system, so if it is fat formated, use reiser fs and then ext3 before formatting it into fat or ntfs again. I've done it this way a few times and with real hard efford I really couldn't find any trace back. But a handy app is offcoarse a more convenient way.

this can help

http://www.hotpixel.net/software.html
download Blowfish Advanced CS 2.57 (files only)
after extracting it and running it there should be an option
under tools that says clear empty disk space
then choose the level of security.
the best is "continous random data".
(but takes the longest but is most secure)
and choose "current location" of what to shred
"make sure you extracted blowfish to the usb you
want erase all the data "
hope that helps

Hello Group; You can

Hello Group;

You can download a program called cybershredder. It is portable. It has one "exe" file and there is a zip version. I have not tried it out on a entire USB drive. But it works with files and directories. Here again I never ran it on my USB but carry it to use on other files.

You can all so down load GPG and WinPT. WinPT does have a file wiper in it. Here again I have never tried it on a file on my USB but on other files.

Me too.

I use cybershredder also. Works great.

But, you would have to have used it from the beginning with that drive. You would not be able to erase traces from previously deleted files. The eraser type programs would handle the entire drive, not just one file at a time.

Hello wsm23;

So the thing to do would be wait for a eraser program that works on the entire USB drive.

Then do the following:

Install cybershredder on to your USB drive.
Back up your entire USB drive.
Run the wiper on the entire USB drive.
Restore your back up to the USB drive.
From then on use CyberShredder on individuall files or directories on your USB drive.

Yes.

Cybershredder is more of a daily maintenance program.

BTW - I have been advised that the very quick shred is sufficient for flash drives. It only overwrites files once and thus saves read/writes on the drive.

I like the idea of

I like the idea of formatting the stick with one (or even two different) Linux file systems before reformatting it with FAT or NFTS. That should be much faster on bigger sticks than any erasing/shreddering method, no?

So to all talented coders out there: would it not be a good idea to write a little portable app that could automate this procedure?
