I have the following problem: “My Passport” USB 3 in encrypted mode unexpectedly disconnects after 5-10 minutes of idle time.
Only the “main” (encrypted data) drive disconnectd; the “virtual CD” always is available.
But when it disconnects, the unlocked state is lost, so I have to run unlocker again.
QUESTION: Is this behavior caused by the drive itself (ex. it has a built-in timer) or this can be caused by USB selective suspend, drive turn-off or other power management in Windows 8.1?
I’ve read the KB article about disabling drive turn-off. This does not help.
This thread is similar but not relevant.
I’ve applied the registry fix (for hardware ID VEN=1058 DEV=0730, and it does NOT help.
The SES device is present and driver installed.
I don’t not remember this problem on the same machine with WIn8 RTM, and do not see it on another machine with WinXP.
