Good Morning,
Just woke up. Us senior citizens still need our beauty rests :-)
Answers to your questions on System Image Disks:
System Image Disk (as I have used the term in my posts) is synonymous with "System Image
Backup" the option on the File History page that is accessed via
Control Panel-System and Security.
System Image Backup is the option you would select to create a System Image Disk. I just use
the term "Disk" because of old habits from past Windows versions although it is somewhat still
currently valid.
When creating a System Image Backup in Windows 8.1 you will have 3 destination options. An
external drive (including USB drives), CDs/DVDs, or a network location. The first 2 being disks
and the 3rd being folders.
The end result after restoring your system from a System Image Backup should contain all
partitions that were present at the time the backup was created but I am not 100% sure of this.
Some of the recovery partitions may change slightly. However, when viewing your System
Image Backup files on the disk or network location, it will not even closely resemble the file/folder structure view of your hard drive. It will look more like a program installation application file
structure.
To restore your machine using your System Image Backup/Disk; you would do it through the
Windows RE Options Menu I discussed previously. From this menu you would select
"Troubleshoot" then Advanced Options" The Advanced Options menu will have the "System
Image Recovery" option which will take you through a menu driven process of restoration.
Your statement regarding when you would use external media is correct except for the case of a disabled drive. Nothing short of replacing the drive will cure a physically bad drive.
The partitions you described that are currently on your system appear typical. I don't see
anything unusual.
Here's the part you will not want to hear. Considering all of your most recent posts, I'd say you
have a defective SSD. If you were not returning the PC, I would attempt to restore it a few times just to see what happens but would fully expect to have to replace the hard drive in the end. It may come back for awhile as I've seen before because bad hard drives can be very intermittent. The symptoms are very elusive and insidious. They can work fine for months passing all known
tests with flying colors.
Another member of this forum mentioned a laundry list of diagnostic tests that should reveal a
bad drive but this is not always the case. Troubleshooting any sort of problem on a bad hard
drive is unpredictable at best.
Hope this helps!
