    I did this with HP CDWriter 7500e & Redhat 6.2
    /sbin/insmod parport
    /sbin/insmod parport_cd
    /sbin/insmod paride
    /sbin/insmod epat
    /sbin/insmod pg verbose=1

    CDRECORD:
    cdrecord -scanbus

    But if it's a hardware problem, try this:
    HP7200i, which refuced to write more than aproximatly 1 cm of
    each record, I used the fix found from http://www.rict.freeserve.co.uk/cd26.htm
    and now it works fine. That is an IDE drive and I use it with Windows98.
