rate3 "Sonic DriveLetterAccess". Component of Sonic CD Burning software. Preinstalled on Dell Computers and others. Locking up CD drive sometimes in conjunction with tfswshx.dll (also belongs to DLA). When shutting down Windows often generates message like: "DLA is processing operations for another user" even if no other user is logged on. Not known as dangerous - yet.   MK

rate1 Sonic Solutions has one slight glitch. When shutting it down, it apparently fails to notify Windows that it is shutting down, so when you start Sonic Solutions again, it reports that it is already running. So when I shut down Sonic Solutions, I use the Windowns Task Manager to end the program and that solves the problem. I don't know whether the add-on in question has anything to do with this problem or not, but I agree with many of the other posters the it simply came with my Dell Dimension.   Rational Geezer
rate1 Have a dell its on my laptop but I also have roxio and sonic don't think its anything to worry about but I disabled it in my browser just in case   mshy
rate0 it came with my dell 2400 6 years ago and i have been using it ever since. if it comes between sonic and IE 8 i will go back to IE 7   sailray
rate4 I just installed Microsoft IE 8 and Sonic Drive Letter Access isn't compatible with this newer version of Microsoft IE 8, if you continue running this dll file on your pc you risk the chance of crashing your computer and loosing everything you have with it - Microsoft Internet Explorer 8 is willing to assist in searching for a fix to the error messege received after installation is completed of IE 8, The. Sonic is pre-installed on F "DriveLetterAccess Component" add-on version '1.0.0.1' published by'(Not verified) Sonic Solutions' is not compatible with Internet Explorer 8.  See also: Link   Cisco Steve
rate0 i think it came with sonic solutio on my Dell labtop   maria
rate2 I disabled the Sonic add-on, microsoft support wrote that it would still function outside of IE8, which is the real conflict, but it did NoT--my XP system crashed   JL
rate0 It came preinstalled with my dell laptop it allows you to copy and burn cd's and dvd's   JTG
rate5 I have several computers Gateway ltd l 300 pent 3 and a Dell Dimension 82000 pent 4 freezes and crashes of IE8 and eventually the system needed to be totally reinstalled on both the common threads were the Veritas DLA and also Sonics record now with DLA both using this DLL it was so bad on one I had to Do a clean install. LOL never a fun thing with xp also for those of you wondering why only one of your Burners works its because the Dla only supports one Burner at a time you have to go in a switch Drive assignments from burner to burner its listed in the User manual from veritas so Beware   Doc Jimi xmasterdarkx
rate1 Drive Letter Access (DLA) is a CD/DVD writing application. It is very popular mainly because it was and still is shipped with a majority of CD and DVD recording drives.  See also: Link   Ax
rate1 I found that I had a program called Sonic Update Manager in Control Panel and once I removed it my problem went away. Sonic Update Manager   John Burgbacher
