I'm not 100% sure what checks are ran at boot up, but I believe every 30
reboots it will check the file system ( someone else might be able to
confirm  if I'm right or wrong on this ).

However what I am suggesting is a full surface scan you can try
www.ultimatebootcd.com . Boot of the disk follow the menus and test
disk. Sometimes the WD tests might not run for whatever reason, if that
happens try running the seagate test..it should still be able to run a
generic test on it. Also sometimes in the past I have had to change some
HDD controller settings in the BIOS to allow it to run the tests as well
( just remember to change them back after before you boot up into ubuntu
again ). 

Your ubuntu drive hopefully is perfectly fine, but worth ruling out. I
had the temporary freezing a little while ago..and eventually stopped
booting, it ended up being a bad hard disk, so worth at least trying to
rule it out.

Its also worth doing the surface scan on the new hard drive that your
having issues with...sometimes you will get a faulty one, and if that's
all it is then its just a case of returning and exchanging it.

Weird?!?!
You think there is another tool called gsmartcontrol, but ccan't
remember if its any good, you could try that if you wanted.

Yeah..just for testing..you can always put them back after ( as long as
you don't have raid or anything set up ).

you could also try booting up off of a 14.04 live cd to see what
happens..if it acts fine in the live cd, then at least that might
indicate that the drive is fine, and maybe the problem does lay within
your ubuntu system or the hard drive its installed on.

If it still acts up on the live cd ( try the 14.04 and 14.10 cd ), then
that may point to the drive itself.
