CD problems: /mnt/cdrom and /dev/cdrom
While I can access data CDs at /mnt/cdrom, Mandrake's software manager looks for CDs at /dev/cdrom.
Even when the correct CD is inserted, mounted and accessible otherwise, the software manager keeps asking to insert it at /dev/cdrom.
There is another problem with my CD, that might or might not be related to this one: sometimes, when I try to take a CD out and try to unmount it, the response to umount is that the device is busy. I have no idea how to get rid of that.
Any ideas?
Thanks

/dev/cdrom is a device file, whilst /mnt/cdrom is a mountpoint. rpmdrake will just use the device directly, and extract data by making it's own temporary mountpoint. make sure you do have the /dev/cdrom link on your system, if not, create the link:
ln -s /dev/hdX /dev/cdrom
where X is the letter corresponding to the ide channel it is conencted to ie.e a, b, c or d.

My Mandrake software manager also did such things until I was advised here to remove all rpm sources and then redefine then.
I did it, and ever since I have no problems with the software manager.

I have the exact same problem,
I've tried making a symlink as described above, but it didn't work. I tried making a symlink by doing:
ls -sf /dev/sda /dev/hdc .
It didn't work so I tried:
ls -sf /dev/scd0 /dev/hdc .
Still didn't work. Wouldn't I need to remove any symlink that doesn't work before making another one?
What is the command to remove them so I can re-do it? I still struggle with command-line...
Fstab shows my cdrom is /dev/scd0.
Dmesg calls it device sda.
What would be the correct way to write it?
TIA,
Siri Amrit

check to see that no other programs are accessing the cdrom - an example is a terminal having a pwd of the cdrom (ie, you had done a cd into /mnt/cdrom/whatever, and didn't cd back 'out' of the cdrom), or same for file manager or whatever you use to access files.
