OK, I got a little dramatic on the title.

While digging up specs on hard drive storage, I came across some information on humidity that is often overlooked.

The maximum humidity ratings for hard drives, SS Drives, and other related media is around 90%. Buried in a sub note there was mention of "non condensing" humidity. This is where things get dicey. Condensation + Electoronics = Trouble.

Be sure to pop one bag into each of the evidence packages before sealing them up. If evidence is re-opened, be sure to replace the desiccant bag and dispose of the old one properly. Re-using desiccant packages is NOT RECOMMENDED! There is no way to tell how much of their capacity has already been used up. They only cost about 14 cents each so there is absolutely no reason to skimp!

If you are using a fire-safe, gun safe or a secure container with little to no ventilation, it may also be a good idea to use a desiccant canister as well.

Uline is a great resource for low cost evidence management products. They have desiccant bags, anti-static bags, seals and tamper tape.
