Caveat

WARNING!!! Do not follow this procedure unless you have a basic understanding of how to format hard drives and you know that you are definately working with a hard drive that contains no important data. The process can cause you to lose all of the data on your hard drive.

Procedure

If (after installing LinuxMCE) you would like to add a brand-new (BLANK) hard drive to your Core/Hybrid to add additional storage space for Media you can use the following procedure:

• Install the physical hard drive into the computer
• Check that the BIOS settings all look correct (Hard drive boot order etc)
• Boot up LinuxMCE and ssh into the core.
• Create a partition on the disk using the fdisk command (you should have read up on this before you use it)

ie. sudo fdisk /dev/sdX (for a SATA drive where X is the number of the new drive)

• Create a filesystem on this new partition (XFS is the recommended option)

ie. sudo mkfs.xfs /dev/sdXY (for partition 'Y' on SATA drive 'X')

• Watch the screen of your nearest Orbiter for a few minutes to see if the new partition is automatically detected.
• If it does not get auto detected then reboot the core and it should be auto detected.
• Tell LinuxMCE how you want to use the new drive (ie as an Internal Drive that uses the LinuxMCE structure etc)
• Reload the router.
• Enjoy your new storage space.

Example

user@dcerouter:/dev/disk$ sudo fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x3272b98c.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.


The number of cylinders for this disk is set to 243201.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
