I installed Win7 reluctantly back in September 2010 having been a solid Linux user for some 4 years – I mainly wanted to be able to check out and use some of the leading Amateur radio software packages – My first impressions were good and I soon got used to using it – all my scanners/printers/drives/and accessories ran fine (In the end), after some minor problems, but nothing that some googling could’nt resolve.
Today I needed to install drivers and software for a new Laser printer so having placed the disk into the cd tray and closed it waited for the install to begin - NOTHING happened and checking under My Computer discovered that the cdrom icon had gone! (So how am I to install software)? I powered down and re-booted but still nothing – I checked again in the Bios and it appeared , along with an external drive I had connected but win7 was not seeing it, nor was it displaying icons for either player.
I ran some disk utilities and a couple of disk scans to see if I could locate any problems and sure enough after some four hours found a problem with a registery entry, either it was broken - or worse, a virus!
This was certainly not the sort of problem I’d encountered with any win installation as cdroms are normally one of the first things to load up under “Win”, I recall early Linux systems had major cdrom issues but they had long vanished.
A re-install from the win7 disk at least proved it fired up ok, but did not help my cause – discovered that one “Fix” that appeared on more than one forum was to go into the “Registry Editor” and find an entry for the cdrom section – It’s a bit involved so have included the link here it seems that certain software adds 3rd party cdrom filters on your system and places an entry in the registery as was the case on this system, and disables access to any cdroms on your system be they built in or external USB – it’s probably nothing new but I’d not experienced this before – Having made the necessary deletion in my case (lower filter) re-booted and all the connected drives appeared like magic, imagine my relief as in the months gone have accumulated a whole bunch of files and information I really do need right now – I had visions of re-formatting and installing Linux again !
I hope I’ve seen the last of that problem !
