Unhappy mounted as: /dev/hdb3 but listed as /dev/hda3

Hi ,

In a Master/Slave configuration I tried to add a second hard drive which already contained Linux. The result was that I could not load Linux anymore (on either drives).

I have 2 questions:

I get the following message:

"The root partition in /etc/fstab has a wrong root device, it is currently mounted as:
/dev/hdb3 but listed as /dev/hda3"

(it also says see article at but the article deos not bring me any answer).

Question 1:

How can I change the mount name (or name in list, which ever is safest and easier)

Question 2:

How can I use 2 hard drives with Linux?
I have files on both drives and don't want to do a clean install.

I am a newbie, please be specific.

Thank you for all your help.

Well, check your bios. What hard drive do you boot from? And to change listed name, edit /etc/fstab, but you need to know which of two.

What was the configuration before you changed it? Linux on one drive?

The first thing I would do is make sure it still works the way it was. Suppose that you are using drive 1, AKA /dev/hda, and the BIOS is set to make that the first drive. Installing another drive should not affect the booting of the first one. To be sure, however, check the bios to see what it sees when both are installed.

Next, you will need to modify the bootloader configuration on #1 to correctly point to the Linux install on the 2nd drive.

Also you might want to check your master and slave jumpers on your drives. I had them switched once and the boot up was confused.
