Trying to add a third hard drive (hdd) and get Unable to open /dev/hdd
 

When I boot my computer using the cdrom and "linux rescue" I can fdisk and mkfs the disk fine. I can access the drive, copy files, mount the drive... etc.

But when I boot up my fedora core 1 it can't find or detect hdd anywhere. I looked at the /proc/ide/hdd and the stuff in here looks more like a cdrom then an hd. my hda is the same model and size as hdd.

How to I get fedora to detect the new hard drive? Any help please.

What does the output of dmesg say for /dev/hdd?

If you have ever had a CDRW or CDROM drive for /dev/hdd then you might have a hdd=ide=scsi line in your boot loader.

Delete and reboot.

Have you updated /etc/fstab?
If you haven't, you should. Try "man fstab" or "man mount" for help on updating it. I just checked my /proc/ide/hda, and it also identifies the driver as a cdrom. Strange...

About 10 minutes after I wrote this I found an option in my grub.conf file.

kernel /vmlinuz-2.4.22-1.2149.nptlsmp rhgb ro root=LABEL=/ hdd=ide-scsi

Then I remembered this computer had two cdrom drives when I first installed it with RH 7.3. It's been through many upgrades and I forgot I removed the two cdrom drives and replaced it with a DVD writer and moved the cd writer to my windows machine.


Thanks for the help in any case.

From the Graphical User interface go to System tools--> Hardware Browser and check whether your hard Drive is senced it so that yoiu can see the device name as /dev/sdb1 etc , once you know this you can mount the same hard drive and add the line in /etc/fstab.

Now you can access this drive.
