1.8g5 tower dvd ejects all media

heeeyooooo

i have two g5 towers...i am selling one and the dvd burner, of course, doesnt work in the one i want to sell... so, i switched out the burners in these machines....

since switching them all media is ejected; regardless of burned~ factory cd or dvd....all media gets ejected....i assume its simple but cant figure out why?

i reset cuda i think... button hard to press so i assume i reset it... should i try master slave combo change ??? i unscrewed the small screws reading somewhere it might be that... ???? any other suggestions ???

thanks

also the quicktime i installed keeps crashing at its launch...could the two be related?

Check the cable connections. The four pin power cable is extremely difficult to remove, and replace. Master slave should not come into it if this is an optical drive. Is it possible the hard drive has failed? Boot from your install disc, surely you have one with two G5's, and run Repair Disk from there.
