reboot caused by boxcryptor and USB block device

aquarius

Hi,

Boxcryptor 1.3 causes some trouble on my Win XP box with SP3:

When an encfs is mounted and I plug in a USB block device, it takes some seconds and my PC reboots.

When the USB block device is plugged in first, the PC instantly reboots, when the encfs is mounted.

Regards,
Aquarius

Hello Aquarius
How does your PC reboot? Do you get a blue screen or does it just break and restart or can you see any error messages?
What USB device do you use and does this restart also happens with other USB devices?
Best regards

Hi Robert,

The screen turns black and then the BIOS boot message appears. It happens with three different USB flash drives. I did not check with USB hard drives.

try to uninstall boxcryptor and see it still reboots.

also make sure EldoS Callback File System DRIVER is not installed.

Without CBFS and Boxcryptor, everything is fine. Right after I reinstalled Boxcryptor 1.3 plugging in a USB flash drive causes a reboot. The problem did not exist with version 1.2.

then try to uninstall again and try this application SFTP Net Drive from same company that does CBFS

http://www.eldos.com/sftp-net-drive/download-release.php

and install it "its small and can be uninstalled" run it and insert your usb. If reboot happens then the problem is found otherwise its maybe from boxcryptor side.

I tried SFTP Net Drive as suggested. The reported versions are sftp 1.0.18.54, driver 3.2.103.256.

Plugging USB flash drives is fine, no reboot.

I forgot to mention, that die reboot only occours, when a crypted folder is mounted.

And I encounterd a reboot on yesterday, when editing a Ms-Word document on a boxcrypter drive.

yep that sounds like a invalid memory or illegal instruction caused by drivers with USB block device. I don't know what else to say except use 1.2 or wait for a 1.3 fix if they can test it with USB block device.
