detecting cd drives
 

hi

i am writing a program in java that uses the cd drives. i was wondering if there is a command in linux which can tell me if there is more than one cd drive installed and what type it is. Or if anyone knows if there is a java command which will achieve this

thanks

Welcome to LQ.

What distibution are you using?

To detect CD drive on the system ,you can try this

Check for directory /proc/ide/hda,hdb,hdc,hdd

If directory present , look for file 'media' inside directory.
Ex:
$ cat /proc/ide/hda/media

This will tell you what type of device that ide is.[It will have cdrom for a Cddrive]

A scan on all four ide`s media files [hda.hdb,hdc,hdd] can find out the number of cddrives in the system.
Also see the 'model' file for the Modelname of the media.

If you need a command to check for media try

$ hdparm -i /dev/hda [or hdb,hdc,hdd ]

This gives information about the ide.
