Thanks so much. I looked at the set up manual (never knew one existed) and there's a nice diagram about where things go. Guess I expanded memory in the past. But is it really OK to upgrade my firmware (I already know which versions I have and need) on this old drive? It does seem the simplest thing, but someone told me that in rare cases, upgrading your firmware can render your machine useless... I hate to live in fear, but is this true? And how rare is rare?
