Thanks for replying Zack. I have had a look at this and I have misinformed you. I was reading thread about a D drive before I posted.Here is my second attempt.
I have bought an Acer Desktop PC with a 320GB hard drive advertised. When I look at my computer the manufacturer has labelled the C Drive ACER (C:). Currently it seems to contain everything including programs I have installed and pictures and documents transferred
from my old PC. It shows 82.6GB free of 139GB.
The other drive has been labelled by the manufacturer as DATA (F:) and appears to be empty showing 142 GB free of 142GB.
The computer has Windows Vista Home Premium pre-loaded. It didn't come with any discs but I used the pre-loaded utility to create a system recovery disc.
There is a D drive but it and an E drive are labelled Removable Disk (D:) and Removable Disk (E:). The only other drive is labelled BD ROM Drive (H:)
If F is a recovery drive then I will leave it alone. If as the name given suggests it is intended for data such as documents how do I get programs etc to use it instead of the C drive.
Thanks,
Hugh
