Hi there ,

these are the messeges that i get when i'm trying to mount a cd

Mar 25 18:09:59 andrei kernel: EXT2-fs: unable to read superblock

Mar 25 18:09:59 andrei kernel: isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16


the problem is that i can mount the cd once or twice after that i get these messeges.

i'm trying to find a solution since two weeks....think i've tried everything..

i have a HP xt1000 laptop with a cdrw/dvd combo from sony.
i don't think there is a hardware problem...if it would be it shouldn't work at all right?
i've tried to disable supermount...to disable autofs...everything..
obviously not the right thing

any hint would be appreciated.l

thanks guys.

?
