Don’t know if it’ll boot from USB. She might get a SSD for it. You can use trim in Windows Vista with a Samsung SSD, if you use the Samsung utility. I should bring my Todo Backup USB drive, I can use it to clone her old drive to the new drive.
Burn Clonezilla to a DVD in case I can’t boot from USB. What thumb drive has Todo Backup on it?
Buy a dual bay USB 3.0 HD dock, and use her laptop, it has USB 3.0. And those are expensive, USB 2.0 will have to do. Or clone the drive to an image file, and then restore it to the SSD.
