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. > > If you have FreeBSD 8 somewhere, it could also work. > > Maybe you can even "go back in time" and use of the > > older live system CDs (converted for USB booting) > > from earlier versions (v8, probably v7 and v6) which > > had mount_ntfs in the OS. > > Actually, I have a FreeBSD 8.2 i386 installation on an > IDE hard drive, now in a Sabrent USB 2.0 enclosure, no > longer possible to update on that hard drive partition. In how far do you want to update that 8.2 installation?

Possible. You hardly know what they put in their proprietary products because they usually don't tell anyone. :-) > File system is too big to make a full copy, no place to put it, 5 TB.

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. > Or there could have been a defect in the NTFS. That's also possible.

Nice, an "un-DVD". Ha ha! That's _business_, man! :-) I'm surprised that it worked on Haiku, an OS hardly known... > FreeBSD 9.2 installation on USB stick is too old to be > readily updatable; easier to start anew with 10-stable > or 11-head. That's probably the best way to go.

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. > There is/was even a FreeVMS project, but that seems > to have died, website no longer there. This one? ---> http://www.freevms.net/ 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. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
