Device driver for Sonic CD/DVD burning software
  Todd S.  
while running flask mx 2004, DRVNDDM.SYS crashed it
it's very irritating
  Gijs Middelkamp  
It's caused two random crashes over the last week.

It was causing a BSD, so I searched for the file. Seems it was a system file for IBM DLA (this was on a ThinkPad laptop). I uninstalled IBM DLA, and the blue screens stopped.
It causes one or several crashes during browsing, running DVDs or maybe just doing nothing. It sometimes several re-boots (some of which may fail) for the system to stabilize. The problem is so enigmatic that it takes ages to dicover the root cause to be this Sonic Driver. Interrogating the appropriate web-page at Sonics supplies "page unavailble due to excessive demand". Well, that's the first non-surprise

It caused BSOD at XP pro IBM laptop
go to start run and type in msconfig. Click "ok". Go to the startup tab, and uncheck tfswctrl. Click apply, then Close or OK. Reboot when requested to.

BSoD as I turned off computer. sonic page says to either upgrade, disable or uninstall. I don't know if I can uninstall it since I use itunes to burn discs. Not sure how that works. I linked to the help page from Sonic below.

it made my computer crash...i hate drvnddm.sys
It sucks. It crashes for no apparent reason, and is almost impossible to reproduce on demand. However, BSOD nails it every time.

Best practices for resolving drvnddm issues

A clean and tidy computer is the key requirement for avoiding problems with drvnddm. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the drvnddm.sys process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
