Mauro is correct. You should make sure that the heads that read the info from the drive are “parked”. Typically, it is very easy to do simply by highlighting the drive while it is attached to a computer and going into your systems option and preparing or parking the drive in preparation for removal. The specifics depend on the operating system you are using.
The other issue is once the drive heads are parked and the drive is removed it should be stored in an anti-static bag and should never be packed using packing “peanuts”. The peanuts seem to cause a great deal of static. Electronic media is highly susceptible to electro-static shock.
Whatever you do, no matter how safe you are, you probably won’t be able to read the drive in 10 years anyway.
