When I leave my computer idle for a while and come
back, my AcomData Drive won’t work properly.
A: The most likely cause is that your computer is going to
sleep. The immediate solution is to restart your computer.
To prevent this problem from recurring, go into your Energy
Saver preferences and set it to never go into Sleep mode.
The Drive feels quite warm when powered on.
Is this dangerous?
A: When in operation, the Drive may feel quire warm to the
touch. This is normal.
Performance seems to be slower than 480 Mbps.
A: First, in order to reach USB 2.0 speeds, you need a connec-
tion that supports USB 2.0. If the connection only supports
USB 1.1 the Drive will operate at USB 1.1 speeds (up to 12
Mbps). The Drive will auto-sense the speed of your USB port
and adjust between USB 1.1 and USB 2.0. Second, 480 Mbps
is the maximum interface transfer rate of USB 2.0. Actual data
transfer rates will vary depending on a number of factors.
