so, I happen to have a few machines with electro-mechanical hard drives, located in my attic, I can't move them downstairs, and this winter is so cold that the temperature inside the attic has gone near +1C. Never under zero, but I wonder if it's a deathly condition for my hard drives.

Currently unplugged & unpowered, the winter is cold, and they are not working as heaters, they are sleeping, waiting for the spring.

Will they wake up Alive? Dead? Should I have to be afraid of any damage? :-//


Edit:
I am also afraid about the relative humidity

Just based on my own personal experience, you shouldn't have a problem. I've stored machines in the garage unpowered for years (including a PC/AT dating back to 1986) and they booted just fine when I've started them up. Garage temperature ranges from 5C in the winter to 50C in the summer.

The best way to answer your question is to look up a spec sheet for the drive and see what the non-operating storage temperature range is.
As an example, this random range of seagate desktop drives says -40 to 70C: http://www.seagate.com/www-content/datasheets/pdfs/desktop-hdd-8tbDS1770-9-1603US-en_US.pdf

I will check up spec sheets. I have different models of hard drives, made by different vendors. But yes, I have a couple of Seagate. They are Barracuda 2U, 40Gbyte/SCSI-SCA. Barracuda is a strong fish, die hard  :D

I also wonder if the low temperature will kill CMOS batteries like DALLAS DS1386. Those chips are used to keep the date and time for UNIX, and also the environment's setup for the bootstrap. There is a battery under the plastic of the chip.

If they're all modern drives, I suspect the storage temperature range is similar.  I think you will be fine with CR-style lithium cells at moderately cold temperatures.
