Thanks for replying.
I have run computers for years using a number of logical drives.
I don't randomly reference across the drives, I just use the programs on c: to access the data on d: e: f: etc
I started doing this many years ago, but I guess my main thoughts at the time were to keep the data separate from the programs, as I found it simplified things, I also thought it would put some kind of barrier for viruses/spyware, also simplified my reinstalling if I had any problems as I only had to reinstall OS & programs to c: drive, and then reinstall without worrying about my main data files, it also helped me manage my data making it much easier to sort.
This all started as I got a problem when typing, i.e. the cursor would jump above where I was typing, would add a hash, then go higher adding some random characters, including full stops, caps lock would also come on sometimes? I tried uninstalling/reinstalling the keyboard driver, I run Kapersky and Trend micro online scanners, Avast, Spybot and Ad-Aware, and they found nothing. I run task manager & msconfig to look at what was to run / was running, all looked ok to me.
So I sent it back to Acer, it was a Vista Laptop which I installed XP Pro on, they said too many partitions, ran a Vista recovery and sent it back to me.
What are your thoughts?
