hi

whenever i put a cd into my cd drive ,i can see its contents in the /media/cdrom but i cannot copy them to my hard drive,it gives an input/output error,

the following is the corresponding line in the /etc/fstab file

The Cdrom cannot read a part of the disk because either the CDROM's lense is dirty or the cdrom is dirty or scratched.

clean the cdrom with a soft cloth (like the ones inside of glasses cases)

i am not sure,but u seem to get the impression that i cannot read a part of the disk.in fact ,i cannot read any part of my cd .the problem is not with the drive because ,whenever i put a video cd(in the VCD format) and play it with mplayer(asking it to see it as a video cd in the VCD format) ,it does without any hasles.

ne how,how to clean the cddrive inside without dis-assembling it?

you can buy cd-drive cleaners in computer shops.. it looks like a normal audio cd, but it has a soft brush on the surface and some lense cleaning fluid.

is this the problem with All data cd's or just a few ?

i get input/output errors often on my backup cd's but this is usually caused by dust, and fixed with a quick wipe with a damp cloth.

the problem is with all disks.i dont think the problem is withthe cd rom because earlier it worked fine in mandrake and windows

hmm... then i dont know what the problem is....
its unlikely that it could be a permissions problem, but just to rule it out, try reading the cd again while logged in as root.

also... next time you get the error, open up a terminal and give the command "dmesg" is there any usefull information about a cdrom error ?

sorry, this problem is above me.... could it be a coincedence that the cdrom stoper working as you installed the new linux distro ?
do you have any other computers with other distro's or operating systems... try using the cd-rom in a different computer... if the error follows the cd-rom then it is possible a hardware error.

are you comfortable taking the cd-rom apart ? it will void the warrenty, but cleaning the lense with a very very very soft artists paintbrush and cleaning fluid does wnders bringing old cd-roms back from the dead.

I think the fs type is wrong in fstab. Data cd's are iso9660 . Never heard of subfs.

tried changing it to iso9660,nopes no result

then try changing the FS type to auto... some dataCD's follow the microsoft standards instead of the ISO standards

yeah.i did try changing but that didnt work even..


both for iso9660 and auto,my cdrom is not even getting mounted,i am unable to see even the files in the cd,which earlier i was able to

Can you explain wat all those arguments after fs=auto mean?may be the problem iswith them
