How long can a hard drive retain data?
I'm not talking about constant use here. Lets say I buy a brand new drive, throw a few files on it and then set the drive aside for 50 years. Will the data still be there? It's use that destroys hDs not time? or :geek::doh:

Data is stored as magnetic impulses which degrade over time. Use does damage a HD but so does time. usually the MTBF (mean time between failure) value is an indication of how long.

I would think the life time would significantly improved if you could hang the drive on a computer like every 2 years or so, shift some data around, run a defrag so the magnetizing would be refreshed.
If you store that drive right (cool and dry) it certainly outlasts every Tape/CD/DVD/Flash drive.

I think your biggest issue might manifest itself in the incapability of obtaining proper hardware and drivers to read your stored disc in the distant future.

The information on a stored HDD might outlive you but I wouldn't trust its veracity after more than 10 years.

As far as DVD's go, I've read claims from manufacturers of a life span between 30 and 100 years.

You will have to refresh your hardware way sooner than 50 years or you won;t be able to read it on anything. I wouldn't trust any optical media that uses dye for any period. Your best bet right now is to use the latest magnetic technology - disk or tape, make two copies, and refresh it every 5 years.
