DI30's like to die three months after their warranty is up. We have a customer that has gone through three of them, and they don't even backup every night. They may be replacing that system in the future, and we told them that as part of the new one, they would have to replace that drive. They didn't want to invest in a new drive and tapes just yet. They are using the onstream software to back up with.
I hadn't heard that they had gone out of business though.
