I am running Windows XP Virtual Machine in Windows 7 Professional (64 bit). From time to time I get the error message "drive is not accessible" with the submessage "incorrect function" when I try to access one of the drives on the host operating system.
The problem occurs reliably when I run Microsoft Developer Studio 4.1 (Visual C++) and work with a project on a drive on the host (e.g. \\tsclient\c). After compiling and running the project, Developer Studio locks up and has to be stopped with the Task Manager. As soon as I exit Developer Studio, I can access the drive again.
The computer is a Lenovo W510 with an i7 820QM processor and 8 GB RAM>
I am very disappointed that the Virtual is so unstable. I have a number of older programs that I need to run on this computer for my business. Any suggestions?
