Specs<br />
Read or write speeds slower than<br />
expected.<br />
Deep Dive<br />
1. Test optical media in another drive of the same<br />
type in same type of computer to rule out media<br />
issue.<br />
2. Check with known-good discs—Install discs that<br />
came with the computer.<br />
3. For disc write issues, check with known-good<br />
media that performs well in another computer<br />
and drive of the same type.<br />
4. Check both CD and DVD media. If only one type<br />
of media is producing errors, there might be a<br />
laser related issue. (J99)<br />
Check Result Action Code<br />

recognized and reads reliably.<br />
3. Disconnect optical drive by<br />
lifting SATA cable at logic<br />
board and connecting a<br />
known-good drive. Verify that<br />
