I've had something similar with usb3 sticks. It could use it for
multi-GB backups on all of my pc's, except for one. On that one
pc they would fail after a random period of time and weren't seen
as usb devices. I had to power-cycle the pc to fix it.

This may not sound helpful for your situation, but I worked around
the problem by splitting the backups in chunks, small enough for
the pc/stick to "survive" the complete backup. Maybe you can do
the same when syncing your collection (but see below).

What happens if you power off your phone, remove the card, plug it
into your pc, chckdsk it and just put in back into your phone?

That's not surprising: from the app's information I infer that it
looks at the information hard-wired into the *on-card controller*,
not at the file system or contents of the card's *storage area*.

By "less data" do you mean "considerably less data" (chunks of
e.g. no more than 1 GB)?

Note that the cause may not be the sd-card at all, but your phone
being unable to handle *both* the usb and sd-card data stream. You
may want to try to force-stop all apps except the system apps, then
try it again.
