The 1T data drive on my laptop died and when I went to have a new one installed, the computer repair guy suggested removing my old OS drive (128Gb, having issues, 7yrs old) also and installing a single new 1T SSD. He reinstalled everything he could from my old OS drive onto the new drive and when I set Norton up on this new drive, it doesn't see the backup sets I've made previously. How do I access and restore them?? (The 600Gb of data on my dead data drive is inaccessible unless I send it off for a mega-expensive recovery at a lab so I need to recover what I can from the backups I've made.) Latest Windows 10 installed.
