All right, tomorrow I will request an RMA.

One of the drives only shows one sector bad. I hope I can still get
some/most of my data.

I know that forcing a reassembly lets me mount the filesystem although
at certain point causes a kernel backtrace and I believe most data is
unreadable.

How should I proceed to be able to get most of the data? Will I have
to create a completely new array or can I somehow fix it adding new
disks?

Oh and thanks a lot for the help, I'm still a newbie with raids.
