Explorer Crash WinXP

Windows Explorer crashes while running secure clean free space with CryptoSuite.

Comments/suggestions?

 

Hi Snook,
When you use "Clean free space" CryptoSuite uses the whole hard disk therefore you will get "out of disk space" messages from windows which may appear to be a sort of crash.

From the CS help file.

Using Secure Deletion
Using secure file deletion on files is only available from the Explorer shell interface. Simply right click on folders or files you want to securely delete in Explorer and click on "CryptoSuite - Secure Delete". You can then enter the amount of passes.

To clean free space on your disk drive simple right click on any file/folder/drive and click on the CryptoSuite submenu to bring up "Secure Delete Free Space". When cleaning free space CryptoSuite begins creating a file that will use up the rest of your disk space. As it is doing this, it is securely removing the old data that is stored on it. After the file CryptoSuite creates is the size of the free space, the secure deletion has finished and CryptoSuite deletes the file.

System Restore Points
On Windows operating systems with "Restore Points", securely cleaning free disk space may indirectly cause windows to remove your "Restore Points". This is because "Restore Points" are based on the amount of free disk space you have, and due to the way cleaning free disk space works by creating a very large file, Windows may remove your "Restore Points" to get more disk space.[

 

Gave no indication of low disk space. Granted, the crash occures right at the end of the secure free space delete/wipe. This only occures when the wipe method is set to any value over 1 (one). In any case, the following is provided:

Thanks for posting the event information, hopefully Jason (CryptoSuite's developer) will look at this thread soon - Perth is asleep now, and be able to advise.

 

What...! Asleep...? ...Security is a 24/7 occupation! (being humerous of course)

 

Hi Snook that is quite interesting. I have been looking over the secure delete methods for the next version and havn't noticed anything that could cause a crash just yet. But the information you provided will allow me to find the offending function that is crashing in one of Microsoft's standard DLLs, so thanks for posting the crash information.

 

Thanks for the reply. Just a note, the wipe does complete and the crash occures precisely at the end of the wipe task.

 

I received the same error when creating an image to work on several different machine types. When i put my image on a Dell GX110, everything appears to work fine, with the exception of opening the control panel. the control panel opened once, then everytime after, i receive the:

Has anyone found a fix for it?

 

Running latest version and crash still occures. Did free space wipe, Gutman 35 and was able to recover some files with File Scavenger.
