Won't record

[elaine]

I have the Plextor 16 10 40 on a Compaq 5834 500 mhz celeron, I can record to my hard drive but can't record to disk! It is as if my hard drive won't bring the information to my cdr. Has any one else had a problem like this with the Compaq?? If so how do I correct this. I can record between 3% and 15% before it stops and locks up?? I have tried different reading and writing speeds, and enable caching on and off.
Now have ERROR: unexpected failure reading file cache request timeout encountered (cache is empty)

Read speed 1X Write speed 2X it locked up after 5% writing and opened cdr and listed this error.
HELP HELP

But the test button worked with out showing any errors??
