Linuxhelp _ Hardware Support _ Cannot find second hard disk

Posted by: Storyteller6666 Jun 8 2009, 04:32 AM

I have two hard disks in my computer. One is 500 GB, the other 1 TB. I have Win XP and Suse Linux ver 10.3 installed on the 500 GB disk. No problem.

I can access the Windows partition of that 500 GB disk from Linux. No problem.

The hardware setup in Linux says the other disk exists. But won't list it as a mountable drive or access it or files on it.

My question: how do I access the second hard disk? Is it too large for Linux to mount? Is there a workaround? Or is it something else causing it? I did add the 1 TB disk after Linux was installed. Would this affect it?

How is the drive partitioned and formated? What type of drive i.e USB SATA, IDE etc.

You need to add a line to the /etc/fstab file. You can find lots of help by googling but in a nutshell a fstab line is:
<device id> <mount point> <filesystem type> <mount options> dump fsck


/dev/sda1 /media/disk1 ext3 default 0 0

See man pages for mount and fstab for additional help. You need to create a directory to use as a mount point. To see a list of how all of your drives are partitio0ned use the fdisk command (you must be root)
fdisk -l (that is a small L)

Contents of /etc/fstab file and result of fdisk -l command are below.

It shows the second drive as being a SFS system. It is formatted as a NTFS system. Is there a difference? (both drives are sata).

Your second disk a windows dynamic disk (LDM). You will need to download the LDM utilities

I followed the link, and the updated link, and downloaded the archived package. I didn't like the "You must know what you are doing to use this" message in the readme but will attempt to muddle my way through.

Thank you for the direction to work on.
