hda should be your harddrive not cdrom

hda is CD-ROM Drive, not harddisk:S

This linux machine is not set IDE harddisk, set SCSI harddisk. so, sda is harddisk and hda is CD-ROM Drive. Please check my boot message:

>Aug 19 03:42:27 RHEL3 kernel: hda: attached ide-cdrom driver.
>Aug 19 03:42:27 RHEL3 kernel: hda: ATAPI 24X CD-ROM drive, 128kB Cache, (U)DMA

i can mount another CD-ROM media in the CD-ROM Drive so, maybe the media is wrong. But, the media can recongnize on Windows System.

What the way do check whether the CD-ROM media is correct?
