Grub error with hdd rack

So this is the story...

I have 320 gb sata for file system
500 gb for files

and when im going to plug in a rack with ide hdd it gives me this error while booting

Quote:

GRUB loading stage 1.5.

GRUB loading...
Error 15

Any ideas on how to make it recognize the hdd? all hdds are western digital one master and the two others slave.

Which distribution of Linux are you using?

You have the OS files on the 320GB drive, where did you install Grub. To that drive? The mbr of that drive? The root partition of that drive?

In order to get a clearer picture of your setup, how about downloading the Boot Info Script to your desktop, and then do the following as root user, but replace <username> with your user name:

Code:

bash /home/<username>/Desktop/boot_info_script*.sh

That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop; please copy/paste the contents of the RESULTS.txt file to your next post. That will help clarify your setup and hopefully what the solution to your problem might be.

This is the result:

i use slackware 12.2

According to the script results, your 320 GB sda drive is using lilo to boot, and your 500 GB sdb drive has a Windows MBR (not Grub); so I don't understand where you are getting a Grub error from. Are there any other drives present on start up that might have Grub in their MBR? I think if you make sure your 320 GB slackware drive is first in the BIOS boot order, you shouldn't have any more problems. Let me know how that goes.

Maybe the hdd in rack has a grub cuz last year i had installed linux there...I ll check the bios later cuz now im going for lesson...

So...here i am...back...In bios a can't put for first boot device the sda(320GB) HDD.The BIOS can see only the hdd in the rack when i plug it in...Also 500 GB sdb drive has Windows MBR. Is there any way to change this from its MBR or something else to make the rack hdd work..? Im confused...:S:S Thanx once again...

Did you have your HDD rack connected when you ran the script in post #4? It doesn't look like it, because the script only showed your 320 GB and 500 GB drives. How about plugging in your rack HDD, boot a Live CD, run the script from the Live CD, and post the output. Also, since you can't change your BIOS boot order, we will need to know what boot order the HDDs are in when you connect the HDD in the rack. To figure that out, how about downloading the Super Grub Disk, boot that, and at the first main menu press "c" to get the command line, and do:

Code:

grub> geometry (hd0)

grub> geometry (hd1)

grub> geometry (hd2)

And please let me know what the output of those commands is. We can work from there.

This is the output with the hdd pluged in in the rack..but seems the same but without the live cd...I ll check it now....Wait...

Quote:

It looks like you've first got to get your Live CD to see the HDD rack when it is connected, because currently whichever Live CD you used did not even detect any other drives than your sda/sdb drives. You can always check which HDDs linux sees by doing:

Code:

sudo fdisk -lu

So you probably need to change your BIOS settings for the rack HDD, but until you can get the rack HDD even recognized in linux, it doesn't seem like there is much point to even having it hooked up if it is inaccessible. You might want to also check the jumper settings on the HDDs in the rack.

This is the results from live cd...nothing ..:(

So...listen at this...I press F8 at booting and select 320G hdd to boot and it boot perfect...Now i can se and the rack hdd but i have to correct it from BIOS..not to have always F8 :P
