USB sticks, even though labeled "USB 2.0" can vary in
the speed they can be used. Involved factors are here:
flash storage, storage controller, USB controller,
whole USB stack of OS (drivers, kernel I/O, library
access calls, etc.), and how the application software
reads and writes (block sizes). There are particular
brands or models of USB sticks that work slower than
"the same" sticks (same capacity and specification,
just different manufacturer, or just a later batch
from the same manufacturer of the same model). Sadly
you can only find out about this by using the USB stick.

In how far do you want to update that 8.2 installation?
Or am I misunderstanding something?

Possible. You hardly know what they put in their proprietary
products because they usually don't tell anyone. :-)

Wow, that's really a lot, as _one_ NTFS partition...

When the OS performs a crash, there is a _reason_ for
this. It's possible to argue about the severity of the
reason, if it justifies a crash, but FreeBSD usually
doesn't crash for _no_ reason.

That's also possible. A file system check (read-only)
could be done.

Nice, an "un-DVD". Ha ha! That's _business_, man! :-)

I'm surprised that it worked on Haiku, an OS hardly

That's probably the best way to go. Additionally, the
more recent tools will be more reliable.

OS/2 is history. Interesting and inspiring, but
there won't be much use for it today, I assume.
An exception could be legacy applications from
that era which would probably run best if you'd
just set up a VM, install the original OS/2 in
it and use that.

This one? --->

It's still there, but legacy users (those who
are actually intending to use VMS software)
tend to prefer SimH and OpenVMS, for which
HP (the current owner) still provides licenses,
as far as I know.

Otherwise refer to SYS$LOGIN:LOGIN.COM;1. :-)
