On this note... We have about 5000 Double-(blue) and 3000 triple density(green) Carts, due to the sensitivity of the data on them, company policy prohibits us from transporting them to the mother ship who is in the process to devouring us, even though they are encrypted, so how do you destroy them, in a eco friendly way if you cannot even sell them on. I personally think that the companies that sell them should take them back without charge and do the destroying under supervision of internal auditors of the companies involved.
Any experience from you guys that have gone thru similar situations?

We once had an issue with overwritten tapes and asked a company specialized in recovering data from damaged media for our options and they simply said it was impossible to recover overwritten data.
