Question Cannot find new added harddisk

Anyone can help me ...

I only have installed one harddisk (hda) on my system. To add a new harddisk on existing system is to enlarge space. There is some problems on it.

Checking new hardware did not find my new added harddisk (IBM ATA/IDE 61.5Gbytes) while I start Redhat 7.1 (BIOS can find this harddisk too). I also used command "/sbin/mkfs.ext2 /dev/hdb" to create partition and it showed "/sbin/mkfs.ext2: No such device or address while trying to determine filesystem size"

I do know whether Redhat 7.1 supports 61.5GB or something is wrong on my system.

check out the nhf on on adding a new hard drive. follow it step by step and then if you are still having problems we can address them. that nhf is very easy to follow and should get you going. you will need to run fdisk to create the partitions and then format them. hope this helps, linux should see that HD if yur BIOS does.

Upgrade your bios. If your bios is, say 2 years old, it might have that 32 gb limitation. If you don't want to play around with your bios, you should check out the hd manufacturers website for a program that bypasses that limitation. I had this problem with win98, so i'm not 100% sure this is the thing you should do with linux, but it's worth trying.

First you have to partition the disk, and then run mk2fs on those partitions. fdisk or cfdisk will make the partitions, while mk2fs makes the filesystem on those partitions Assuming you are certain that this hard drive is /dev/hdb, which means you've made it the slave on the primary IDE channel:

cfdisk /dev/hdb

This should show however many Gb of empty space: chop it up into partitions, make sure to give them the label either Linux or Linux Native (means the same thing), then run mk2fs on say /dev/hdb1

From there you're going to have to mount the partition, and then add a line to /etc/fstab so you don't have to mount the thing by hand every boot. Its pretty intuitive after that first bit.
