I am not sure why you couldn't read/copy them if you have tried that.
As for writing to them or changing permissions or ownership, it could
be that the files have some flags set on them.   Then, not even root
can modify them without removing the flag[s].   See  man chflags.

If that doesn't help, are you ready to just leave that data behind and
move on?   If so, you will probably want to rebuild the partitioning
on the array.   You might want to wipe out enough stuff to make sure
to avoid any possible conflicts (probably none, but...)  To do that
use dd and overwrite the first few hundres sectors or the logical device.
If you address the array as  ad1,  for example,  do:
  dd if=/dev/zero of=/dev/ad1 bs=512 count=1024
Then fdisk it and bsdlabel it and newfs partitions you create with bsdlabel
and if it is all happy, then you have a cleaned out working 'drive' again.
