When mounting some FireWire/USB devices through a Tableau write blocker the Activity LED remains solid for a long period of time. Whats wrong?
Some drives have a filesystem structure that Windows wants to interrogate extensively upon mounting, which results in a potentially large number of small I/O requests. When mounting these drives through a Tableau USB or FireWire write blocker the Activity LED remains on constantly during this scan. This process may take 10-60 seconds, but once the scan is complete the drive may be imaged or browsed normally.
