I am using a stock hp pavilion 1183cl laptop.

I upgraded to Win7 ultimate 64 bit full install, I did a clean install on drive C.

I saved alot of stuff i had previously on the D drive, important documents games music videos etc.

So after installing Win7 everything seemed perfect and in working order then about an hour or so after my d drive disappeared, it would only reappear after rebooting or after the computer came back on after going to sleep.

Now i have tried doing driver searches and other scans of the computer to make sure drivers are up to date with no luck.

Can someone please help, HP forums is useless!
