hard disk and sub flash disk issues

[Ralf Mardorf]

Hi,

first of all immediately unmount any file system or swap that still
might contain data fragments you wish to recover. It could be possible
to partly recover lost data, but it's very time consuming work and
nobody subscribed to this mailing list can do your homework. Google is
your friend. We can only help you, if you describe a recovery procedure
you try to do, but got stuck with it. It's easier to rescue a deleted
file, than to rescue data from a reformatted partition. Trying to get
back data could be days of work to no avail at all. As long as you just
lost data you may not necessarily need, consider to not waste time to
get the data back, instead spend some time to learn how to make (real)
backups, to be prepared in the future.

It's possible to repair thousands or more of broken Debian and Ubuntu
installs, as long as the installs are broken. If the thumbdrives are
broken it's impossible. If its worth the effort depends on the result of
troubleshooting. The subscribers of this list can help you step by step,
if you do your homework first and provide more information.

The hard disk might not require a recovery, maybe something else is
fishy. Feel free to post the output of the commands you already run.

Is there any question you have related to the machine with the USB port
you removed?

You are running a persistent Linux install from a thumbdrive? Nice, you
can use it to recover everything, but how about getting one machine
without broken hardware and a regular Linux install first, before trying
to recover tons of lost data, broken installs on probably broken
thumbdrives etc.?

After at least one machine without broken hardware and without a broken
install is available open one thread after the other to get help with
repairing broken things.

Recovery and repair of a bunch of broken hardware and/or software by
using this broken stuff to repair it makes absolutely no sense. It's
possible to repair a broken system by itself, but it makes no sense
trying to repair such an accumulation of fishy things via a mailing
list, without having a reference machine on your side that is working
correctly.

Regards,
Ralf
