OS Discs getting ejected

[glocke12]

so i found someone to buy my 2007 SR MBP. IT is currently running SL, so I am trying to wipe and reformat the HD. I inserted the original software discs (10.5), and it gets ejected, than I tried inserting the SL upgrade disc, and that gets ejected.

The drive accepts and recognizes other discs, but not the OS discs. Any ideas as to what is going on?

Could be that the drive needs to be cleaned, or perhaps its on the way out?

The OS discs are dual-layer, see if you can find another DL disc and see if it will mount. If you can't boot off the super drive, you could format a usb thumb drive and install from USB.
