Add Second Drive - Problem not seen by fdisk
I just added a second IDE hard drive to my Linux Red Hat 9 system. It is recognized in the Bios. When it boots up, I see it say /dev/hdb in the initilization. But when I go into the shell to try and run fdisk /dev/hdb it returns "Unable to open /dev/hdb"
Is there something I have to do to reconfigure Linux to recognize the drive. It has not been formatted or partioned yet. I would appreciate any help, as scans of the net have not yielded any clues. |
Try putting this line in your /etc/fstab:
/dev/hdb1 /mnt/hdb1 ext2 defaults,users 1 1 Also make sure that the /mnt/hdb1 directory exists |
Can I do this if /dev/hdb is not recognized?
|
If I am not mistaken, that will make it recognize the drive, then you could mount it, then format it (or is it format it, then mount it?)
Anyways just give it a shot and see if it works ;) |
I tried it, and now I'm in a real bind. I get an error on boot up and saying it has a mount error - doesn't recognize /dev/hdb1 and its lost in a cycle of reboot. Unfortunately being a newbie, I am not sure how to navigate around the command line to reedit the fstab and delete the addition. Any help? Which command editor line should I use?
|
Ok, I got my bind fixed. Used vi fstab in the command line and removed the line I added to fstab? Any other ideas?
|
try this at a command-line:
vi /etc/fstab delete the /dev/hdb1 line then reboot. As for getting your drive to work, I dont know. Making the addition to the /etc/fstab worked fine for me. Sorry I couldn't be of anymore help :( :( |
Thanks for the attempt. I am really confused. I thought Red Hat 9 would recognize the drive and reconfigure the system and then all I had to do was run fdisk. Maybe I am doing something wrong. It a Maxtor 160G ATA/133 drive. I'll play with the bios settings and see if that does anything. Any other help would be appreciated.

Heres a question:
When you were running the redhat installation program and you get to the part where you set up your drives/partitions, is the drive listed? If yes, use that utility to format it. If no, well... then I don't know.. |
It's been a while since I ran the Red Hat Installation program. When I did, I only had one drive. It is set up as ext3. By the way, the error I get after I added the line you told me in the fstab is:
modprob. Can't locate module ide-disk fsck.ext2. Possibly non-existante or swap drive. fsck.ext2: No such address ... to open /dev/hdb1. I can't read my note on the "..." As for the Red Hat Install, do I need to rerun it from the CD? I'll give it a try. |
Yes, try to re-run the program. You dont actually need to re-install anything, just run it up to the point where it asks you to set up your drive(s)/partition(s). If you see your drive, then format it, and all is good :) if you don't, then I really don't know what you can do
|
Does the bios recognize de drive all-right?
|
It asked me about the drive during the install, but it didn't ask me to format it. I then tried to run the fdisk /dev/hdb again and came up with the same error. Oh by the way, do I just kill it after I get there, because I wan't sure if I should update my bootrecord. I replied yes.
|
dabicho,
Yes. The bios sees the drive just fine. |
And youre running fdisk as root?
