DRIVE REPLACEMENT.
I've just done a drive replacement for my N100, and this was my experience:
Backup your music and playlists first!
120GB system/cache drive to 500GB (mSata - 500GB was the best value)
4TB hard drive to 4TB SSD (Samsung Evo - 8TB too expensive for now)
Ideally, you will have a Linux box (I did mine on a low spec Raspberry Pi).
1. Remove the mSata system drive and put it in a mSata to USB enclosure (cheap on Amazon).
2. Assuming you have at least 120GB free space on your Linux box, plug in the USB enclosure and do (all as root) fdisk -l to get the drive ID (typically /dev/sda or /dev/sdb)
3. Find/make a suitable output folder - I used an attached SSD mounted to /media/OneTB
4. Using the dd command, create an image, i.e. dd if=/dev/sda of=/media/OneTB/N100.img and let this run (can take a couple of hours on a low spec machine)
I did an image rather than a straight copy for saftey and backup, you could if you have both old and new drives connected do a straight copy, being VERY sure you select your original N100 drive as the input (if=)!!!
5. When done, remove the original N100 drive and insert the new mSata drive, and copy the image to it (it might also be /dev/sda or might be /dev/sdb - use fdisk to check): dd if=/media/OneTB/N100.img of=/dev/sda
This might take several hours..
6. When done, install the new mSata drive in the N100, plus the new SSD (no need to format the new SSD)
7. Boot up and ensure the N100 is running ok (note there will be no music drive...yet
8. In conductor, do a full factory restore (wipe music etc.) and this will fix up the new cache drive and initialise the new SSD music drive.
Copy music back as required - various ways - I hade mine on a spare drive on my Mac, then use conductor to restore playlists (if necessary - I did not do this as I wanted to start fresh.
Good luck.
