Hi, I've been into the registry

everything was as you said except there wasn't any UpperFilters ?? Anyway I thought I'd just do as you instructed and I deleted the LowerFilters and hey the drives are back
Thank you very much and thanks to Snooker who also pointed me in this direction.

Now about that blue screen on system restore........................... think I'll leave that until I actually need to use it!
Thanks again, don't know what the likes of me would do without the help from these forums!
