cdrecord read error

[Sidney Abrahams]

I used cdrecord to copy my data file backups to cd every day on Linux 9 Red
Hat. I recently upgraded to Enterprise WS and now the cdrecord gives me:
Cdrecord: Input/output error. Read error on input file.
Yet I can use kde audio burner software to burn that same file to a cd??
The cdrw is configured on dev/hda, while on my old system it was on fake
scsi dev=1,0,0. cdrecord cannot read/write to ide devices?

Help?
