No medium found

Hi,

I am using

RH 9
HD - 40 GB
RAM - 128 MB

I am a newbie. I recently removed the cable that runs from the mother board to FDD. I am unable to mount any cd's. Inspite of inserting data CDs, I get 'No medium found' error. My CD-ROM is detected as /dev/hdb. My /etc/fstab has the entry '/dev/cdrom /mnt/cdrom' alongwith the other parameters (Sorry! I am not at my machine now). But the funny things is when I do eject, my CD-ROM pops open!!!

Am I getting 'no medium found' because I removed my FDD IDE cable?

Or is there something that I am missing.

Thanks for your answers.

Well, why don't you put the cable back in and see what the problem was?

I myself wouldn't know what the problem is, but i guess the first thing i would have done is put the cable back where it belongs.

I hooked back the cables and I still cannot mount my cd. Here is the message I get

mount /dev/cdrom /mnt/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: No medium found

Here is my output of dmesg | grep hdb

ide0: BM-DMA at 0xa800-0xa807, BIOS settings: hda

MA, hdb

MA
hdb: SAMSUNG CD-ROM SC-152C, ATAPI CD/DVD-ROM drive
hdb: attached ide-cdrom driver.
hdb: ATAPI 52X CD-ROM drive, 128kB Cache, DMA

I inserted the installation CD and get 'no medium found'... please help

Thanks

What does the line in your fstab look like? Mine is:

Code:

/dev/hdc        /cdrom          auto    ro,user,noauto  0 0

edit: Investigated the matter.

Code:

lotheac@lotheac:~$ sudo mount /dev/cdrom /cdrom -t iso9660
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: Mediaa ei löydy [medium not found in english]
lotheac@lotheac:~$ sudo mount /dev/hdc /cdrom -t iso9660
mount: block device /dev/hdc is write-protected, mounting read-only

My /etc/fstab looks like this

LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda3 swap swap defaults 0 0
/dev/sda1 /mnt/usbstick vfat user,noauto,unmask=0 0 0
/dev/hdb /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

I get the same error message when I

sudo mount /dev/hdb /mnt/cdrom -t iso9660
mount: block device /dev/hdb is write-protected, mounting read-only
mount: No medium found

Thanks

I have been looking into this for over a week and now it seems I have reached a dead end. Either no one has encountered these problems or ppl are too busy to help this poor bloke out !!!

Changed the subject.... cos I desperately need help

Thanks

When you insert a CD does the drive spin or do anything? Is this a dual boot system or do you have any other method to verify the drive still functions?

Try booting up the PC with the 1st install CD to recovery mode. If that does not work I would suspect a bad drive.

vaneeri · 07-20-2004, 09:24 AM

Thanks for the reply.

Yes my drive works when I tried to boot from the CD.
No this is not a dual boot system.

Please help!!!!!

Try changing the line to this

/dev/hdb /mnt/cdrom auto ro,noauto,user,exec 0 0
