/dev/hdc probably is owned by the disk group, and it is a bad idea to
add users to that group because it allows direct read/write access to
all hard disks. The user can easily overwrite complete file systems
using dd. Better change /dev/hdc group to cdrom, or use ide-scsi
emulation instead, so you can access the drive through /dev/scd*, which
belong to the cdrom group.
