I have a win7 64-bit system that cannot read burnt CD-R's (even ones it burnt itself!). How can I troubleshoot and correct this?

Just replace the hardware. – Ramhound Oct 2 '12 at 19:06

If the discs can be read fine on another PC, try a good DVD lens cleaner and see if that helps. If it doesn't, change the DVD drive.

So you think there's not way to fix the existing one? – MAW74656 Oct 2 '12 at 18:28
The drive has separate read and write lasers, so if one is malfunctioning I'm not sure what can be done to fix it. You'd probably need to take it to a hardware repair shop, but given how cheap DVD drives are nowadays I highly recommend you simply get a new one. – Karan Oct 2 '12 at 18:54

Well replacing the hardware made no difference, which confused the hell out of me. But on accident, I realized that the drive could write but not read from win7, but it could read within XP Mode! XP mode was taking over the drives read capability!

So, I shutdown the XP Mode VM, changed its CD drive to none instead of the physical (Because I don't need it in XP Mode usually), and viola! I can now read CD's again in Win7.
