Unhappy unable to see the files from my cdrom after mounted for a while...


hi, please tell me this is not bug and maybe my configure problem...
ok here's the situation:


i got a lot cds (mp3, avi, dat, etc..) burned from windoze OS. and when i put those cd in my cd rom, i see all my files under /mnt/cd-rom.
which is cool...

but here's the problem, whever i'm doing something with the cd rom (like play music out of it using xmms, or using mplayer watch movie, or even copy and paste files from cd rom to hardisk)

after a little while, all the files from /mnt/cd-rom "magically" disappear . in order for me to see whats in (or do something with) /mnt/cd-rom again, i have to eject the cd from cd-rom, and insert back in. (or umount then mount cd rom again)

this gets very annoying, at first i thought maybe it has to do with how FAT32 / NTSF FS is diff then Ext3, so i burn another cd with full of mp3s without folders and directories (in hope that linux don't have to go from 1 folder to another folder to play songs and cause these songs disappear). but the problem is still there,

now lets say if i have 3 movie files on my cd, if i wanna watch second movie after i finished the first one, i have to eject the cd-rom then insert the disc back in order to see the second movie files. anyone else have similiar experience and suggestions?

thanks in advance

Sorry man I don't know. Strange you have this in 9.0. I had a similar problem + other CD-Rom related problems in 9.2 and that's why I downgraded to 9.1

Maybe something about Mandrake "supermount" file-system ? (which is not a standard linux kernel feature "still")

I agree that its a supermount problem. As you probably have figured out already supermount allows one to use a removable media like cdroms without using the mount / umount commands. After a period of inactivity supermount will automatically unmount the cdrom.

If you close whatever broswer is accessing the drive at the time and reopen the broswer the CDROM should be mounted again. The other solution would be to disable supermount and then use the mount / umount commands.

if i don't wanna use supermount what is the "correct mannar" to mount and umount a cd once i put that into my cd rom?


is it like:
1) insert cd in cdrom
2) mount /dev/cd-rom /mnt/cd-rom iso9961

then when i'm done with it i go:
1) umount /mnt/cd-rom
2) eject cd????


thanks

oh yea 1 more thing... lets say if there's 50 songs in my cd, and i played 10 so far, and problem occur again.

if i close the brower and reopen again (assume supermount will remount it) i can only see the 10 songs i was playing, i can't see the rest of the 40 songs.

so hopfully this give you better idea if its really supermount causing the problem

I don't remember the exact syntax for supermount. See man pages for details.

Since the device is in your fstab file no need to use fs type. You can mount by either mount point or device ID.

To mount:
mount /mnt/cdrom

To unmount:
Close all apps acessing drive
umount /mnt/cdrom

Once supermount is disabled clicking on the cdrom desktop icon should mount the device. Closing all apps and right clicking on the cdrom icon and selecting unmount will unmount the device.
