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.
