There are some known problems with high density hard disks and long storage in a powered-down state.  They can lost data in the same way that DRAM does only on a much longer time scale.

A month is probably OK but it might be marginal at the terabyte level.

I have read about folks who send big hard disks around for DVD mastering jobs reporting data loss.

There seems to be no problem with disks that are powered up continuously or at least regularly.
