BSOD when unmounting & removing DT Lite

[syuzee]

I have an HP pavillion laptop running on Vista 32.

After havind D/Led and installed DT Lite 4, all went fine up to a certain pont when BSOD started to appear from time to time when unmounting virtual units. On occasion it took me to manually remove the virtual USB from system.

Finally, DT refused to mount whatsoever unit/image.

I tried to re-install it but BSOD appeared when uninstalling (actually when the uninstall program runs some kind of registry modding application).

I tried uninstall DT by miself (both via the control panel and the DT sidebar menu) but it failed, BSOD again.

Please, don't aske me to post the minidump here - my PC can't read dmp files and I don't want to install some other weird MS software in order to do that. But I can send it by email if you provide me an address.

Many thanks to all who will be of help to a useless Italian girl.

You don't have to post the contents of minidump files, you only need to upload it here either as an attachment (zip it first) or upload it to a file hoster like megaupload.com.

Also which exact version of DT Lite did you install?
DT Lite creates virtual SCSI drives, not virtual USB drives.

Hi Blaz,

I'm actually on DT Lite 4402-0131, I believe it's the latest release... as per your suggestion I attached a zip file containing the last minidump.

As you probably have already understood, I'm not really into DT, usb & similar issues.

When my DT Lite started giving me troubles while unmounting units, I searched the web & found a hint to try and unmount things from the system folder... there I found something that sounded like "virtual", "usb" and "daemon" (but I may be mistakening some word, my memory isn't that good either) and removed it.

The strange thing is that this seemed to work, since every time after doing that DT allowed me unmounting the unit w/o BSODs... or I was just lucky ;o)

I really appreciate your help, ty so much.

Probably caused by : dtsoftbus01.sys ( dtsoftbus01+1be6 )

Please try to enable Advanced Emulation in Settings -> Advanced, this will remove the usage of above Simple Driver and then please try again.

Note in current DT Pro there is a newer dtsoftbus01.sys included and therefore the BSOD may be already fixed.

Hmm... it didn't work. I set Adv Emulation to Advanced, DT started installing SPTD, but after a while BSOD again.

And this time it was a hard one, upon restarting Vista went to resuming mode, worked on it for a long while, then told me that resume had failed! But at the second restart Vista loaded correctly.

No minidump file was generated this time.

Please try to install latest SPTD from DuplexSecure - Downloads and then reboot and retry with Advanced Emulation.

I downloaded SPTDinst-v178-x86.exe, the version suitable to Vista 32, tried to install it but without success. It says that SPTDinst-v178-x86.exe isn't a Win32 valid application.

Any guess?

You have to redownload the setup.

[syuzee]

I did it, and now everything seems OK! I tried mounting & unmounting several times, and no BSODs!!

Ty so much, Blaz, you're my fav German helper

I'm getting the same issue as well with it BSOD upon removal of the device.

Sorry I wasnt able to upload it as a zip file the page kept on timing out so here it is unpacked.
