I have just done a clean install of W7 RC on a Dell Inspiron 1545 and all seems well EXCEPT that the DVD drive randomly disappears from explorer and device manager, then reappears if I open or close it - any intervention really..
it doesn't seem to be a driver problem - it simply drops out and says its 'not connected', then comes back if I open or close it.
I have physically removed and re-inserted the drive and it seems it's seated Ok, any ideas please?
It worked perfectly OK to do the installation and I am not aware of any problems with it prior to me installing W7.
It's a TSST corp TS-L633B ATA.
