BSOD with new dvd writer help

[Ogami]

I just today got a new Pioneer 107 to replace my Pioneer 106 and now I'm having a prob and can't get either of them to work!

I have never had any problems with my 106 so I installed my new 107 and booted but before windows had loaded properly I got a BSOD which said "kmode exception not handled" some numbers and at the end it said "cdr4_2k.sys"

I unplugged the new writer and rebooted and all was OK, no BSOD only prob is my network card was uninstalled?? I reinstalled that and all net seems to be working OK now! So I plugged in the writer again and same prob, BSOD with the same error message! I tried booting in safe mode and same BSOD!

So I took the new writer out and put the trusty old 106 in instead and guess what, same BSOD

Does anyone have any idea what may have happened and what the solution is? I'm at a loss with this...do I need to delete the offending cdr4_2k.sys file?

I'm running win2k pro SP4 and the system has been stable right up to the point where I put this new writer in this morning!

plz help

OK, I just had some fun! I seem to have got it working but still would love to know if anyone knows what went on! Here's what I did!

I removed the cdr4_2k.sys file from the system32/drivers folder and put it elsewhere for safekeeping! This meant I could boot into windows with all drives plugged in and not BSOD, but all the CD/DVD drives were unrecognised, not showing up in my computer! When I checked on device manage all the cd/dvd drives had yellow question marks and it said unable to load the drivers!

So I then went to cdrom drivers.com and downloaded another version of the cdr4_2k.sys supposedly for winxp! When I put this in the system32 drivers folder and tried to reboot I couldn't even get into windows, just kept giving me the blue screen with if you have installed new hardware blah blah, unable to load driver system32\drivers\cdr4_2k.sys! I tried safe mode and still this blue screen!

So I had to go back to my windows CD and from the recovery console delete the offending driver! I could now boot into windows but same hardware prob because no driver was there!

So I thought what the hell and got the old cdr4_2k.sys driver that i moved for safekeeping and put it back where it came from in system32\drivers. I rebooted and hey presto everything seems to be working OK! No BSOD, all hardware seems installed OK according to device manager, CD's are reading from all drives OK. I have not yet tried to burn a dvd with this new drive but am pretty hopeful, and will let you know if I fail on that!

I know PC's are tetchy but this has taken the proverbial this morning! Does anyone have any idea of what may have gone wrong with this as I'm obviously interested to find out what went wrong and what happened to repair the problem!

Thanks in advane

Did you set the master/slave jumpers right?

Also did you make sure the bios knows your changed your equipment because some of them store that info in nvram & thinks the old stuff is still in your computer so won't recognize the new stuff.

Yeah I checked the jumpers twice...lol...then again, was swapping a secondary master 106 writer for a secondary master 107.

I didn't uninstall the old writer until after my probs started, but the new 107 was recognised in BIOS straight away, i checked it was registering OK before I tried to boot and was deff coming up as a 107!

My only thought so far has been that maybe a registry setting was corrupted somehow and when I had to use recovery console to delete the new cdr4_2k.sys file I'd downloaded it must've deleted the offending registry setting as well! So when I put the old file back it was all good? That's just a guess so I don't know if that's a reasonable assumption or not but I can't really think of anything else!

I've now burned a couple of DVDs with the new writer and having no problems at all, seems fine
