Firstly, what media are you using?
It’s the most common problem …
“I bought this media from ebay/swap meet/suspicious guy in a trench coat standing on the corner/ (insert other hilarious circumstance here) for 2c a disk & the burns are always bad! Do I need a new burner?”
Assuming you aren’t the person in the above circumstance … it could also happen for any of the following.
- UDMA is turned off
- Ide Driver corruption/ not working
- Burning Program Issue
- Aspi layer corruption
- IDE cable not connected firmly.
- IRQ conflicts.
- Burner broken
- CPU overheating
- RAM not installed firmly, or faulty
- IDE cable too long, hence signal degradation.
- IDE cable broken.
This list is by no means comprehensive … but you can start at the top
