[McIDAS #DZN-645110]: McIDAS, CentOS, solid-state drive and Windows 10

Hi Kwan,

I replaced my Windows 7 laptop's 500 GB HD with the same SSD, and I
too saw a remarkable performance boost!  I did the replacement by
after making an exact copy of my HD, and then simply swapped the
drives.

I have cloned drives on a number of occasions, but not for file recovery.
My setup is includes an external, USB drive on which I keep all of my
perishable data, presentations, etc.  I then backup that drive to another
drive, so I have two copies of everything.  This requires that I update
the backup disk periodically, of course.

This sounds like your laptop is poorly designed wrt cooling; you have
a fan that is not spinning freely or has failed; or you need to clean
(blow out with compressed air) the cooling pathways.  I have found
that I need to use canned compressed air to clean out the cooling
pathways ever month or so.

So, this is saying that your HD was not the cause of the overheating.  Again,
I suspect a bad fan and/or a need to clean the cooling pathways (or a poorly
designed laptop coolingwise).

re:

They may be.

re:
> Have you experienced such CPU overheating shutdowns before?

A couple of times, but that was before I took to cleaning out
the cooling pathways routinely using canned compressed air.

Cheers,

Tom
