Somehow, this reminds me of the trouble with MSDOS-formatted floppy
disks: when they are written to on several computers, and especially
on a mix of Macs and PCs, they get corrupted easily. That was because
of the drive heads being aligned slightly differently, I thought. But
some things seem to remain...
Two issues:
Cheap memory sticks are made from cheap flash chips. They tend to
have a short life. Cheap vs Inexpensive. The market is flooded
with crap nand memory these days.
And the windows-compatible file systems used are *fragile*, very easy
to corrupt.
Re. USB hub: This one has 7 ports, of which 2 are used by an Apple
mouse and a non-Apple keyboard, so plugging in a stick as the third
shouldn't overload its power supply, one would assume.
Never assume. I've seen a number of USB sticks die because their
power handling circuitry was damaged. The resulting short was enough
to destroy powered hubs and even the built-in USB interfaces in your
Mac. The OS tries to protect you from this, a little - if it senses
something amiss, it shuts down the interface quickly.
