I've found the problem here was the wrong cdrom device used. It should be the /dev/scd1 or just the /dev/cdrom symlink. I was tricked by the syslog and believed that the Virtual CD was /dev/sdc, as the virtual floppy device /dev/sdd has always been working as expected.
blkid /dev/sdc /dev/sdc: SEC_TYPE="msdos" LABEL="scrtch" UUID="4BC4-E724" TYPE="vfat" "fdisk -l /dev/sdc" returns nothing. mount -t vfat /dev/sdc /mnt/cdrom/ mount: No medium found ls /dev/disk/by-id/ -l total 0 lrwxrwxrwx 1 root root 9 04-13 22:23 scsi-36a4badb0083ed00012ec7e5a0882f342 -> ../../sda lrwxrwxrwx 1 root root 10 04-13 22:23 scsi-36a4badb0083ed00012ec7e5a0882f342-part1 -> ../../sda1 lrwxrwxrwx 1 root root 9 04-14 14:38 usb-iDRAC_LCDRIVE_20080519 -> ../../sdc lrwxrwxrwx 1 root root 10 04-14 14:38 usb-iDRAC_Virtual_CD_20080519 -> ../../scd1 lrwxrwxrwx 1 root root 9 04-14 14:38 usb-iDRAC_Virtual_Floppy_20080519 -> ../../sdd lrwxrwxrwx 1 root root 9 04-13 22:23 usb-Kingston_DT_101_II_0019E06B084B5B99050D0126 -> ../../sdb lrwxrwxrwx 1 root root 10 04-13 22:23 usb-Kingston_DT_101_II_0019E06B084B5B99050D0126-part1 -> ../../sdb1 ls -l /dev/cdrom* lrwxrwxrwx 1 root root 4 04-14 14:38 /dev/cdrom -> scd1 lrwxrwxrwx 1 root root 4 04-13 22:23 /dev/cdrom-sr0 -> scd0 lrwxrwxrwx 1 root root 4 04-14 14:38 /dev/cdrom-sr1 -> scd1 The virtual cd/dvd/iso image can now be mounted successfully via /dev/scd1 or /dev/cdrom. Just don't get what the usb-iDRAC_LCDRIVE_20080519 /dev/sdc is. Thanks again for your help!
