The problem with this discussion is my portable version is on an internal hard drive. So why is this degrading?

Nothing else on this drive has any trouble and I've checked, and there's no file system errors nor any fragmenting.

USB drives do need to be unmounted before removing them, otherwise there is
the risk of file system corruption. Precisely the same is true for external
hard drives, floppy disks, or any other writeable medium you can temporarily
attach to a computer.

I've never seen a USB thumb drive fall apart, and I think they're considerably
more robust than floppy disks, which is basically what they replaced. You can
also drop them on the floor with a good deal more confidence of them working
afterwards than if you drop an external hard disk.

Yes, they're vulnerable to static electricity; that's why most of them have
plastic caps to put over the contacts or a slider to retract the contacts into
the body.

My experience is that if they're treated reasonably they work very well. If
they're mistreated they'll give as many problems as any other mistreated
storage medium.

A few years back, I had a job for three years where people brought me their
files on USB thumb drives. These things are horrible in terms of
long-life. The really do have to be unmounted prior to removing from the
computer or they get corrupted. They physically fall apart easily. And,
the hardware inside seems to be more vulnerable to static electricity data
loss than other portable drives, certainly more vulnerable than most
computers.



I would think that would be the problem.

I've noticed over the past couple years that my portable install of nvda
will sometimes degrade or get a bit corrupted over time all by itself
while the installed version is always stable as a rock. Does anyone know
why this is and is there any way to prevent this from happening? I use
the portable copy to test a couple add ons and if the portable version
corrupts, it can make it appear that the add on is defective or has a bug
while it really doesn't. Deleting the portable copy and making a new one
will clear it up. I also notice a few functions of nvda either don't work
at all or nvda gets very sluggish in responsiveness and this all gets back
to normal after a complete flush and remake of the portable version. As I
say, this never has happened at all with my installed copy on the same
computer.
