Hi, Rafael,
 
I am using internal WDC laptop HDD. I will give SDD a try even though I only have non-Intel SDD now.
 
Is your SDD the boot disk (by swapping the built-in HDD out) or the extra one installed using device bay on Dell laptop?
 
Thanks,
Jian

What kind of disk did you use?  Mine is an Intel SSD.

They aren't relevant to this issue.

No, I didn't.  Unfortunately, I won't be able to do any tests on the affected
machine in the near future (most probably for the next two weeks or so).

Thanks,
Rafael
