DVD does not mount with scsi off

[DimGR]

After i removed scsi emulation for the DVD it stopped working. It is an old DVD drive . Should i leave it with scsi?

hdc: CREATIVEDVD-ROM DVD2240E 09/27/97, ATAPI CD/DVD-ROM drive

end_request: I/O error, dev hdc, sector 64
isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16


my fstab line

/dev/hdc /cdrom iso9660 defaults,ro,user,noexec,noauto 0 0
/dev/hdd /cdrom1 iso9660 defaults,ro,user,noexec,noauto 0 0

( hdd is my CDRW and it works fine )

2.4 kernel, you need emulation.
2.6 kernel, you do not need emulation, but some progrmas need the emulation.
So I would suggest keeping the emulation.
