Chapter 7 – Tips and Known Issues
Known Issues
64-Bit Kernel Support is Incomplete 
If you need to work with P2 memory cards, you must boot your 
computer in 32-bit mode; otherwise, Qio offers 64-bit kernel 
support. Please contact Panasonic regarding 64-bit kernel support 
for the Mac OS P2 driver.
Some ExpressCard Adapters are Not Properly Recognized 
When Hot-Plugged Into the Qio Enclosure  
FireWire and combo FireWire/USB cards will not operate when 
plugged in while the computer is on. Cards inserted into the Qio 
enclosure at startup will work without issue.  
Occasional Slow Wake from Sleep 
When storage devices are attached to an adapter card inserted in 
the Qio enclosure, your computer may occasionally take several 
minutes to wake from sleep. Sonnet expects to resolve the issue 
in a future software update.
Sleep Not Supported With P2 Memory Cards
If a P2 memory card is present in the Qio enclosure and its 
volume is mounted when you put your computer to sleep, the 
volume will unmount and a Device Removal Error warning 
will appear when you wake the computer. This is an issue with 
the Panasonic P2 card Mac OS driver. Sonnet is working with 
Panasonic to resolve this issue. 
Slow Initial Startup After Software Install
When you first turn on your computer after installing the drivers 
and the adapter and connecting the Qio enclosure, you may 
experience a very long pause (around four to six minutes) at 
the blue screen before the desktop appears and the OS becomes 
usable. This issue only occurs on the first boot with the adapter 
card installed; consecutive boots will not exhibit the pause.
Tips
Hot-Plugging Cards
You may hot-plug and hot-swap memory cards in and out of the 
Qio enclosure. However, you must follow proper procedures for 
ejecting volumes or else you may lose data on the card or cause 
your computer to behave unexpectedly. Do not insert cards into 
the Qio enclosure while your computer is sleeping.
Hot-Plugging the Qio Enclosure
Hot-plugging the Qio enclosure is not supported. You must 
connect a power source to the Qio enclosure, and connect the 
Qio to its adapter card in the order described on pages 4 and 5 
of this guide. Memory cards and adapter cards may already be 
plugged into Qio when you turn on the computer.
Selecting Power Off Card from the Finder Menu
Do not select Power Off Card from the Finder menu.
Drives Connected to Qio are Identified as SCSI Devices
Drives connected to the Qio enclosure’s eSATA ports appear as 
SCSI drives in Disk Utility, regardless their actual interface. This is 
normal and is a function of the driver implementation.
Memory Card Formatting 
For best compatibility, format memory cards in the cameras in 
which you use them. In some cases, a card formatted in Qio will 
not be recognized and must be reformatted in the camera.
Device Drivers
When using adapter cards, some of them require additional drivers 
and application software to operate or have full functionality. 
Software should be included with the device, or available to 
download from the manufacturer’s web site. Check the peripheral’s 
user’s manual for information about necessary software.
Powering Devices Connected to Adapter Cards 
Although many peripherals may draw power directly through 
adapter cards plugged into the Qio enclosure, other devices may 
draw more power than Qio can provide and require an external 
power source. Remember to use external power supplies when 
necessary.
SDXC Card Support Requirements
The memory card adapter included with Qio can support 
SDXC cards when Mac OS X v10.6.5 or later is installed in your 
computer.
