Browse All Topics A client's Dell 600m is getting BSOD with 0x7E and tfsnifs.sys referrenced. Google and EE searches say to right-click on the CD drive, click on the DLA tab and uncheck the box, or uninstall Sonic DLA. The problem is that I can't boot into normal mode without getting BSOD, and Sonic will not uninstall in Safe Mode; and also there is no DLA tab on the CD drive after a right click. Any ideas?

Try renaming tfsnifs.sys to tfsnifs.old in c:\windows\system32\driver
Then boot in normal mode, and see if it prompts to reinstall the drive....
Or at minimum, remove ALL optical drives from the Device Manager, from inside Safe Mode....
In the Device Manager, select View>Show Hidden Devices
(If the Show Hidden devices is not present, do the following command from a command prompt..)
start>run>cmd
set devmgr_show_nonpresent_dev
Then remove everything under Optical Drives....
More information on that command here....
Device Manager does not display devices that are not connected to the Windows XP-based computer

I've finally gotten back to this unit, and what ended up fixing it was to boot into Safe Mode, rename all three instances of the tfsnifs.sys file (to .syy, just to diable them), pull out the CD drive and then reboot into normal mode. Then I could uninstall Sonic DLA. The points were appropriately awarded.
