Citidisk HDV?
 

Anyone have much experience with these?

We have 4 of them.

2 were working fine
1 was turning on, but stays solid orange, then blinks red and green... but mounts to the computer and formats just fine
the 4th one acts like its' recording, but won't format properly, whenever you plug it into a macbook or another computer it gives disk and intilization errors.

But now 2 of them are staying solid orange and flashing red/green...

The problem is these were all from a rental house (2 look brand new) and they don't know anything about them, the manuals are useless. Annnd we need them for tomorrows shoot, otherwise we'll probably have to go with tapes.

So if anyone has any experience that'd be helpful.
