Problem with IDE-CDRW drive

[Igor Gorbounov <igorbounov voronezh serw ru>]

Under RH-9.093 can't use anymore the IDE CD-RW drive.
Under RH-9 it worked fine. And now:

"mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
       or too many mounted file systems
       (could this be the IDE device where you in fact use
       ide-scsi so that sr0 or sda or so is needed?)"

/dev/hdc is recognised during Linux startup.
"hdc=ide-scsi" exists in grub.conf.
So what became wrong?
