My distro is RH-9, I attached new IDE hard disk (40 GB). It is in Secondary Slave.

It is working fine in Windows. But when i mount in linux

I am getting these error

[root@hari root]# mount -t vfat /dev/hdd5 /hard/e
mount: /dev/hdd5 is not a valid block device.

How to mount my hdd

when i type fdisk -l
this is the report shown

[root@hari root]# fdisk -l

hmmmm......... no idea, did you format it?

If /dev/hda is your new 40 gb disk then you should mount /dev/hda5 instead of hdd5, to fidn out which device is you new hard drive on linux you can do it with dmesg | grep hd , that should tell you what is what, hope this helps

Only a guess Try to mount hdb

Did you post the entire "fdisk -l" output? If you did, then linux is not seeing your "secondary slave" drive. In fact, it is only showing the primary master.

Are you sure that your new drive is plugged in as secondary slave? Do you have two hard drives in your system?

You do have a vfat partition on /dev/hda5. If you are confused about your drive lettering, then I would edit your /etc/fstab and change hdd5 to hda5.

If you're sure that you have two hard drives, and one is secondary slave, then linux isn't seeing it for some reason. Start in your boot up log (probably /var/log/boot.msg).
