Machine spec?
Is -40c the storage temperature or the operating temperature?
How do you know it was the HD that stopped and not something else?

removed hard drive and put it in standing esata case and did the same weird transfer rate up and down on mb/s. stoped drive and tried again and same thing i waited about an hour for the drive to get warm in the living room plug it in and bang works fine
but theres a big but put drive back in computer fine until temp drop am using right now it is running with a raptor 74 that works fine same temp
since temps drops have started to act the same thinking of rma

Very rarely are hard drives rated for that kind of operating temp. For example, the Seagate 7200.12 drives are rated for a nonoperating temperature range of -40 to 70 C, but an operating range of just 0 to 60 C. I wouldn't be surprised if your drives were similar - hard drives don't tend to like the cold while operating.

If Positive it is the drive, RMA it. +10 C (50 F) should not be a problem!

Temp (10C) should be great for Overclocking in winter time, But if no AC summer could be a bummer.

10C is somewhat marginal already for hard drives, and the temp in question is actually negative 10 C, not positive, which is definitely out of spec for all Seagate and WD hard drives at least (all of which are rated 0-60 Celsius operating)

cji - MY BAD, didn't chatch NEGATIVE.

Definitely -10 is below spec. Couldn't think of computing in a room at Neg 10 C. The +10C should however be no problem. There is normally a margin when specified 0 C as the lower limit the test are normally conducted at a lower temp so that they can "Guaranty" 0 C.
Worked on a research B-737. We did runway friction test where they sprayed water on a patch of the runway and after it froze we landed on it. This was done in mid Jan at an airfield in Canada. We had no problems with the HDDs, or computers, in the mornings after the plane had set overnight - It was COLD, don't recall whate the temp inside the A/C was, But definitely below +10C.
The HDDs were normal drives that had been flight hardend to absorb the shocks of landing.

Most hard drives will work below 10C, true, but the reliability does drop off rather sharply as it gets colder.
