new Hard drive
 

I'm sorry, but I can't think how to look this up in a man. If I add a hard drive to my Red Hat 8 system, how do I get it to recognize it? I thought it would show up in Disk Management and all I would have to do is mount it. It isn't there. I can't find it with fdisk either, but my BIOS is detecting it. Is there another tool I need to use? How do I do this?

You will need to:
1) Partition it
2) Put a file system on it (format it)
3) Add an entry to /etc/fstab

fdisk /dev/hdb or /dev/hdc or /dev/hdd ?

Sorry - that makes sense, but how in the heck do you partition and format in this OS? I found fdisk, but it seems to want you to refer to a certain drive and I'm thinking the second drive should be hdb, but it just says it can't open it?

To get a list of disks and partitions try:
fdisk -l

Some people find sfdisk easier:
sfdisk -l

So.. if there isn't any hdb or anything but hda, I have another problem?

(BTW, Thanks)

Possibly - is that what you get?

My suggestion would be to look at the harware setup:
What drives are on what channels?
Are the drives set to "slave" or "master" and "master with slave present"?

hda-primary master
hdb-primary slave
hdc-secondary master
hdd-secondary slave

it's where the drive is hooked up, not how many you have.

for example, for a while i had a single drive hooked up to
a highpoint raid card. it was hde, and the only hard drive
in the machine. i had the cdrom and burner as hda and hdc

Thanks, everyone for your help. It is secondary master and shows up in the Bios, but if I type fdisk /dev/hdc it just says it cannot open that device. If I do a -l it only lists partitions on hda. Must go now, but thanks again for the effort.

you may have had a cdburner at that location before and
your linux is set to ignore that drive for ide setup.
it would be hdc=ide-scsi in lilo or grub that would be hosing it.

cool
 

Thanks a lot for all your help everyone! Yes it was the CD drive thing.

your feedback is appreciated.
