Chapter 7 – Tips and Known Issues
Known Issues
No Mac OS X Snow Leopard (Version 10.6) 64-Bit Kernel
Support
Some third-party drivers installed by the Qio System Installer are
not available in 64-bit, so Qio supports only the 32-bit kernel.
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 be unmounted when you wake the computer and a
Device Removal Error warning will appear. This is an issue with
the Panasonic P2 card Mac OS driver. Sonnet is working with
Panasonic to resolve this issue.
Qio is Not Yet Windows
®
Compatible
Sonnet will enable Windows compatibility in a future firmware
update; check Sonnet’s Web site at www.sonnettech.com/support
for firmware updater and Windows drivers.
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 the Qio to its adapter card (and plug in the adapter if
you’re using a notebook computer), connect power to the Qio
enclosure, and then power on the computer. 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.
