Sony VAIO GXR600 running win2k sp4
WMP7.1, Nero 6 Ultra Edition, DVgate, Intervideo WinDVD, motion jpeg software decoder
After updating wmp7.1 to wmp9 windows wouldn’t load but I could still boot into safe mode, resolved thru thread http://club.myce.com/f34/blue-screen-after-windows-media-player-install-309161/ by uninstalling wmp9 [windows rolled back to 7.1 automatically], wmp9 updates & genie software.
After booting back into windows my Toshiba DVDROM SD-R6012 no longer showed in explorer [or drive management] altho I could see it under hidden devices in device manager. A device labeled Sony CDRW CRX 610E and various matshita cdrom & cdrom scsi devices were also listed.[I guess those are controllers]
I tried various ways of updating drivers on the Toshiba from the Properties > Driver Tab> UpdateDriver Button and finally windows found cdrom.inf and I rebooted. The DVDROM is now visible and “unhidden” in device manager w/ an error 31 code - windows can’t load the drivers - but not visible in explorer.
Uninstalling wimp9 removed cdr4_2k.sys from system32/drivers. When I was troubleshooting the cdr4_2k.sys failure to load windows error I checked that it wasn’t one of the drivers for the optical drive. The current drivers are cdrom.sys; redprop.sys and stroprop.dll. I wrote down the drivers before uninstalling wmp9, but I don’t know where now.
I think what I am supposed to do now is uninstall the device and let windows refind it. I’m a bit nervous about uninstalling it and then it not showing up anywhere. I think the dvdrom is a plug and play rather than a non plug and play. It’s one of the selections when you click the Safely Remove Hardware Icons [it came back there when it reappeared in device manager]. So according to the instructions I just click the uninstall button on the driver tab and follow the instructions, which will probably be to reboot.
Googling error 31 I found mention of an Adaptec plug in w/ wmp7 that causes error31 w/ a failure to undock.
Windows may have “rolled back” to wmp 7.1 w/ a different configuration. Checking the registry entry mentioned in the above link the lower filters list the cdr4_2k which is no longer on my computer [unless it’s in a cab somewhere.] The upper filters show cdr4lw2k, which I also didn’t find in a search in the Windows folder & subfolders. So it looks like a leftover from uninstalling wmp & genie. I backed up that part of the registry and I think I should delete those filters, then uninstall the Toshiba drive, then reboot.
Any other suggestions? Should I also try uninstalling wmp7.1 before rebooting?
