I have had many bad experiences with SATA data cables. On one of my
motherboards, five of the six cables that came with it were bad. Also
the connection is not secure enough. A slight tension from another cable
may loosen the plug enough to cause problems. The same applies to the
SATA power plug. When you work inside your computer case, the last thing
to do should be to check that the SATA cables are properly connected.
