Access "Data" on old Time Capsule

Thanks for your reply, but I don't think that it is helpful.

Until fairly recently, I could click on the icon for my TC from Finder's side bar, and then "data" would appear in Finder (see attached), however, I could then click on "data" and after a short period of time the contents of "data" would also appear in my finder window (i.e., the various sparsebundles for each computer being backed up) and I could view the contents or delete. Now when I click on data I either get the spinning pinwheel or "loading" endlessly, and eventually the error on "force close" that finder has stopped responding, and I need to relaunch. Using the Airport Utility allows me to see the existence of "data," and I could erase or archive the ENTIRE disk, but not an individual (and in this case obsolete and ancient) sparsebundle, nor will it allow me to see the contents of "data".

A little < than 1/2 of the HD available, >200 GB free.

Safe Boot had no effect (see below)

And with a new, admin acc't, it tried loading for perhaps a longer period of time, but ultimately same, unsuccessful time-out.

Like I said earlier, 1) 2 of my computers can still back up to this TC w/o difficulty (but I can't access the contents of "data" on the TC even from those machines w/o the same time-out, and 2) I was able to do so until recently, after deleting one of the old (2021) sparsebundles that was no longer in use (and even then, it was starting to take longer to access "data," with a few unsuccessful/time-out attempts before it would finally mount).

Thanks for your ideas.

Ethernet/LAN

I can try that, but finder never crashes when I search the other network hard drives, including those also serving as time machines.

Different cable, different LAN port tried today stepwise on TC and hub w/o any difference.

Thanks for trying. Guessing something has just degraded on this ancient accessory, but was hoping that there was a fix.
