Sony CRX225E Issues

:confused: Hi, I have purchased a Sony CRX225E CDWriter a while back and while I like the drive I have reciently encountered a small issue. Everytime I try to write to the CD no matter it be an ISO Image or audio right when its prepairing the drive speeds up, then speeds down and makes a grinding / tearing noise… afterwords about 4 minutes or so it then burns to the cd perfectly fine. Now i guess generally speaking I wouldn’t care except for the fact that thats 4 minutes that could abeen used for somethin else seeing as its a 52x burner and also its an annoying sound. Has anyone else had this problem is it something stupid I am missing? Maybe some cheap CDs? please help!
