A couple of days ago I replaced a Lite-On DVD burner with a SONY Optiarc DVD AD-7260S (S-ATA) burner. The firmware was Version 1.02.
I got two Sony's (for back-up).
I started having problems with both of the Sony DVD burners 'staying' installed.
At first I thought it may be the drive (defective) so I replaced the one Sony with the other identical Sony.
For no apparent reason when I start to run ImgBurn or sometimes DVD Player, my Windows XP O/S would hang up (looking for the drive) and I would have to re-boot. Other times, when ImgBurn would indicate that it couldn't find the DVD drive, I could go to the Device Manager and 'disable' and 'enable' the drive and then ImgBurn could find it.
I thought that maybe there was something wrong with the driver, so I went to the Sony DVD site and downloaded and installed what I thought was the latest driver. What I got was a firmware up-date, actually a complete firmware file that up-dated the firmware in the drive from version 1.02 to 1.03.
My first question is the driver part of the firmware?
This does not seem to have fixed the problem. The drive continues to 'disappear' and when a program tries to access it Win XP goes into a loop. Also, sometimes when I re-boot after this happens, the device manager indicates that there is no DVD drive installed (not listed) so I can't do the disable/enable thing and have to re-boot again.
I've done a complete virus/malware scan of the C drive before WinXP starts and after it is running. No problems.
I've had other problems with Lite-On drives, which is why I'm switching to Sony, but never had a problem like this.
Any thoughts, suggestions?
