Google suggests one cause is bad sectors that cause read delays/errors.
Writing to those sectors will allow the drive to remap the logical
sector to a new reserved physical one, if it has any left.  The `quick'
format the PVRs offers doesn't do that.

So it is seen in that it appears as /dev/sdb, or similar, but there
doesn't appear to be a partition table that gparted recognises.

Try `sudo file -s /dev/sdb' and see if file(1) recognises the first few
bytes, though it can give misleading results.  If not, the output of
`sudo hexdump -Cn512 /dev/sdb' can be interesting.

Google suggests `humaxrw' is a command-line program for reading and
writing to that disk.  https://myhumax.org/forum/topic/humaxrw Copying
off all the programs, have Linux write to every logical sector, and then
the Humax format it, before copying the programs back *might* help the
skipping problem.  All at your own risk.  :-)

Yes, it should do.

Cheers, Ralph.
