The drive letter is assigned by the active operating system when you
mount the partition. It's not embedded in the partition so TSK tools
don't display it.
Given that it's the first NTFS partition, the machine this image came
from likely boots from that partition and it's likely assigned letter
C:, but to be 100% sure you'd have to examine the Windows Registry in
the partition or have booted the machine and observed it.
So /Windows/winsxs/Backup likely is C:\Windows\winsxs\Backup
I accept at this point that the drive ketter is irrelevant. But what about Name: x86_microsoft-windows-font-truetype-mingliub_31bf3856ad364e35_6.0.6000.16386_none_c6eae5a23b4a0d1e_mingliub.ttc_b8743970 - its quite a long file name, but googling shows that the WinSxS folder does exist.
And whats more corruption of it may well result in a failure to boot.
Kinda the reason that I am interested in exploring what resides on bad sectors.
I am going to continue to experiment in this area :-) Thanks for your detailed instructions Theodore.
