Hi!
To get a bit more serious again. I read about the new technology they use in the 4GB drive. The heads hoover over the surface like flying a jumbo jet a few feet over ground. That sounds a bit sensitive towards shock or vibration.
I had a bad experience with a 1GB MicroDrive. It tipped over when I did a backup from the SM card to the MD (my camera has got 2 slots). I had the camera standing on the front lense (to get better access to the buttons) and the floor was soft and covered by a rug too.
Height: approx. 13cm.
The result: total loss of data. Head crash. I got a replacement from IBM without any troubles but lots of nice shoots were lost (I viewed them on the TV set before).
I woudln't dare to submerge a MicroDrive, not even when the sea is calm.
What's your experience, so far?
Most of the time I use two 128MB SM alternating and a 512MB CF and 1GB MD for backup. This setting is good for 84 pictures per dive (5Mpix, jpeg 1:8)
