Is disk really bad if mkfs.ext4 -c -c reports errors?

[Ralf Mardorf]

Get a new drive and when buying a new drive, it never harms to buy a new
cable, too. A few days ago I needed to replace the cable of my studio
headphones. The jack most likely is still ok, but I anyway bought a
new jack, too, instead of soldering the old jack to the new cable. FWIW
I hot glued the jacks of my SATA cables with the sockets. It's easy to
remove the glue, but the connection is more secure with glue. I wonder
if SATA cables with clips require special SATA sockets. Perhaps I
should buy and test cables with clips ;).
