How to Backup NSLU Completely

In relation to the post about NSLU hard drive migration. Similar steps can be taken to backup NSLU completely. There are actually some steps listed on NSLU2 linux dot org web site. However, i find the steps listed here to be simplier and easier to implement.

1. Download Clonezilla live CD. Instructions and link in previous post [NSLU hard drive migration]
2. Attached your USB drive to the computer that you are going to Boot up Clonezilla.
3. Follow on screen instructions to choose language and keyboard layout
4. Select device to image option
5. Choose where you are going to save your image. You have the option of local drive, ssh server or samba server.
6. After that, follow the instruction on screen. Choose to savedisk.
7. Follow the rest of the on screen instructions. if everything is successful, you should get your image in the location where you chose to save the image file in step 5.

Migrating NSLU to bigger capacity Harddisk

Finally, i have managed to migrate all my data from my old hard drive (320 GB) used for my NSLU (unslung) to a bigger hard drive (500GB).

The old hard drive is starting to give me problems. For the past two power down of my NSLU, the old hard drive did not start up properly. I have to leave it running for a couple of days before finally, NSLU can boot from it. Fearing for my data in it. I got an external USB raid enclosure for 2 500GB HDD. The challenge is to migrate it smoothly.

Went to google about it. But did not have a solution that meet my needs. Finally, i was introduced to Clonezilla and GParted. These 2 application made the migration a breeze!
First download the live CD for Clonezilla and GParted. Burn the iso images into 2 CD.

Boot using GParted CD. Attached your USB drive from NSLU and the New harddrive into the computer you are booting from. Check the original partition in your old hard drive.

1. Using GParted, create the SAME number of partition on the new disk as in the old disk
- In my old hard disk, i have 3 partition. (One big ext3, one ext3 of about 120MB and one linux swap partition)
- I created 3 partition in the new disk. (1 linux swap partition, one 150MB ext3 partition, the rest of 500GB goes into the 2nd ext3 partition)

2. Once the partition are created in the new hard drive successfully, Shutdown. Change CD to Clonezilla and boot using Clonezilla CD

3. Using Clonezilla CD. Follow the on screen instructions till you reach the step where you can choose "device-device"

4. Then choose partition to partition. NOTE: When given the option, DO NOT set the target partition as the same as the source partition. If you choose to set target partition to be the same as source partition, you will end up having the same partition structure in your old disk (in my case is only 320GB, the other 180GB "went missing"). Choose to grow partition to the target partition size.

5. Repeat the partition cloning for ALL the partition in your old drive you your new drive.

After you have finish everything, Just plug in your new drive into your NSLU. You will have all your setting and all your data as what you have in your old hard drive, with the new capacity of your new drive.

Your iPod needs to be reformatted for use with Windows.

Got a big shock of my life when i connected my ipod (nano 3rd generation) to my PC today.

I saw the message
"Your iPod needs to be reformatted for use with Windows. Would you like to run iTunes to restore your iPod now?

It was working well before, i did not plug it into any other computer.

No knowing if my data and stuff will still be there, i clicked "Cancel".

Went online to look for a solution. I Googled for it and found there are some support site from apple that refer to it but from my understanding, it is describing the steps to follow through instead of how to resolve it.

I went to a few other websites. And follow instructions here and there. Finally, after i plug in my ipod, the message is no more there. Normal operation resumes.

Here are the steps i took;

1. Switch ipod to hold.
2. Swith ipod to UN-hold
3. Press "MENU" and centre button together. Hold down both buttons until the ipod reset itself.
4. After reset, "Off" the ipod by pressing and holding the "play / pause" button
5. "On" the ipod again

After the above steps, i tried to plug into my computer again. And it works! =D
