You are not going to like this answer any more than the previous one, but...
Move to Guardian OS (dump the 4100)...
As for Vista; I think XP will survive longer than most gloom and doom people think. Also, there are alternatives, like OSX, which is moving up the ranks. Or, a bazillion renditions of Unix and Linux. I will stick with XP Pro for now, and see what the future holds.
I do have to tell you, and no harm intended here, but you were a bit hypocritical in your last message, but I understand your frustration at the reply you received when looking for help. You say "
finding solutions for the future instead of longing for the past", "
early adopter and business user", "
We can only hide from Vista for so long before we have to adopt it or give up and move to the woods", and "
but it is what it is". These are your words. Yet you are trying to squeeze more use out of an outdated NAS and SNAP OS. I submit to you that your words apply to NAS units as well as a desktop/notebook OS. Now keeping this in mind, here is the answer to your question, as best I can tell you.
SNAP OS has issues with Vista (and some OSX stuff also). Even the newest version is outdated, being over 2 years old. Adaptec has indicated it is no longer going to update the SNAP OS, thus making it a dead OS in effect. Why? Because their current units (and have been for some time) use a far superior Guardian OS. So, to the best of my knowledge, and to use your words, "it is what it is". I hope someone has found a better workaround for you, but don't expect much. SNAP OS with Vista is known to have "issues" and it is not going to be corrected, at least at this time, according to Adaptec.
Again, I do not mean to be harsh or critical, but it seemed the best way to get the message across. Sorry, but it is what it is, and it is time to move to a Guardian unit, just like it was time for you to move to Vista.
