sometimes my cdrom can not read a cd and linux mixed up and i cant unmount cdrom.on the shell i always see errors and it seems never finish.so i reset the machine or cut the cdroms power (i know it s not true)

what should i do?

First, tell us what error you're getting on the shell. Then, try looking at /var/log/messages to see if the kernel is spitting out relevant messages.

The problem is like that;

en_request:I/O error, dev 16:00 (hdc) sector
hdc:Command error;status 0x51 {DriveREady SeekComplete Error}

like this and it always repeats this like forever i can just reset the machine..

[yowwww]

isn't this the server section? I am confused as to what these categories mean. I'm not sure what cd roms have to do with servers
Oh well.

regarding your cd rom....

see if it is listed in the peripherals.
make sure if you created a desktop icon that it points to the right device.
check all the connections to make sure it is secured properly

It's clearly detected, since accesses to it don't return ENXIO.
It seems to me as if the disk itself is damaged. Does this happen with all disks? It could, however also be that the IDE connector is a bit loose at one end, or that one pin in it is gone or something like that. Do check your IDE connector.

Note however, there are things to do instead of rebooting. You can almost always switch to another terminal and kill the mount process or whichever process it is that is hung. But I must agree, Linux's handling of unreadable CDs is a bit inflexible.

i think problem is ide connector...and i ll try to connect from an other terminal and kill the process..thx..
