I'm wondering if there's anything further I can do to avoid this very unwelcome and serious surprise in the future:
When recently restoring a (different, system/OS) drive via boot to the SRD, I recieved the alarming surprise that each recovery point in the (one, since only one set will fit on the decicated backup destination drive) set for this non-system drive were 'bad' (sorry I don't recall the specific terminology for 'unusable' that the dialog box used).
To try to avoid this kind of surprise, I configure Ghost to email me so I knew each 'bad' recovery point "was created successfully."
I know not to "Ignore bad sectors during copy" thanks to you good people.
There was no "drive architecture" change unlike in my earlier thread.
All hardware diagnostics (hard drives, RAM, CPU) pass perfectly errorlessly.
My theory was filesystem corruption on the backup destination drive (which is 100% dedicated to backup images from one specific job/drive). So I did a full format on the drive and the SRD now has no warnings that the image set is bad. (So luckily I have thus far not lost any data, yay!)
I consider this an indication I may have been correct about filesystem corruption being the issue (particularly since HDD diagnostics were AOK on all HDDs). I guess a better confirmation would have been CHKDSK but there was nothing but 'bad' images on the HDD so I decided not to invest all the hours CHKDSK would take on a 2TB HDD, since I had resolved to Format it anyway.
