Apple docs on using USB Devices with new Airport Extreme Base (802.11n model)
Apple just updated a couple docs related to using USB devices with the new Airport Extreme Base (802.11n compatible model), which has a USB port for "instant USB drive sharing".

AirPort Extreme (802.11n): USB storage devices that use removable media are not supported
"AirPort Extreme (802.11n) base stations, which work with USB storage devices, do not support USB devices that use removable media such as a floppy disk drive or an optical drive."

A reader was considering using a WD USB drive w/builtin cardreader (Compactflash, smartmedia, etc.). But per the above, the cardreader probably wouldn't work.
They also have another AirPort Extreme (802.11n) doc titled Using an attached USB storage device as a home directory is not recommended.

" You should not use a USB storage device connected to an AirPort Extreme (802.11n) base station as a home directory. An AirPort Extreme (802.11n) base station may not be able to locate a home directory on an attached USB device if it is powered off or if the enumeration order of attached storage devices changes. "

Info on Security fix in Airport Extreme Update 2007-001
Although it wasn't mentioned on the Airport Exteme Update 2007-001 page last night, the update included a security fix, mentioned in Apple's new doc titled About the security content of AirPort Extreme Update 2007-001.

" AirPort Extreme Update 2007-001...
AirPort
CVE-ID: CVE-2006-6292
Available for: Mac OS X v10.4.8, Mac OS X Server v10.4.8

Impact: Attackers on the wireless network may cause system crashes

Description: An out-of-bounds memory read may occur while handling wireless frames. An attacker in local proximity may be able to trigger a system crash by sending a maliciously-crafted frame to an affected system. This issue affects the Core Duo version of Mac mini, MacBook, and MacBook Pro computers equipped with wireless. Other systems, including the Core 2 Duo versions are not affected. This update addresses the issue by performing additional validation of wireless frames. Credit to LMH for reporting this issue. "

Review of Addonics PCI-X 4x SATA Multilane Controller
" AMUG has posted a review of the Addonics 4x SATA Multilane PCI-X Host Adapter for Macintosh users. The review also provides images of their new Snap-in drive series that provides hot swap capability without the use of a tray. The article discusses install, stability, sleep and performance.
One advantage of the Multilane setup is that it allows up to four hard drives to be connected in a direct connect configuration with a single 59" long cable.
This host adapter does not support booting and requires the use of an enclosure with a multilane connector.
Best Regards,
Michael Bean

More notes on Mac Pro Firewire and FW Audio interfaces
"I read about about MOTU interfaces having problems on Mac Pros. (latest comments were in yesterday's news, although as mentioned there not only Mac Pro users had problems - so did some PowerPC based Mac owners.-Mike) I found out through another route that Apple made an undocumented (or underdocumented) change to the Firewire implementation in the Mac Pro (only - doesn't affect other models yet) that relates to Firewire audio interfaces like MOTU's. My Metric Halo (mhlabs.com) Firewire interfaces suffered from this problem, and the lead developer of Metric Halo wrote this on a public forum and posted a beta version which solved it for me. (See below.)

I have a MOTU interface too which has the same problems on a Mac Pro. MOTU haven't fixed it yet. -"James"

The reader above had originally sent a copy of Metric Halo's lead developer comments on this, which was actually in reply to another user's forum post (not his) - the user that actually got the private reply from Metric Halo's developer sent a link to a thread at the cubase forums with a clip from the developer comments at http://cubase.net/phpbb2/viewtopic.php?t=64767&highlight= (down the page there).
Another Mac Pro owner wrote with what sounds like the same issue:

"Here's my posting on uniconation regarding problems with MOTU firewire.
(he included a link to the posting but it requires a login apparently)

FYI, I have the problems using built-in FireWire AND Cinema Display hub.
MOTU, so far, has been slow to acknowledge or fix anything in my case.
Anyone experience this problem with the Ultralite or any other MOTU product? I have the the latest MOTU Universal Drivers.

What happens is that my Ultralite will work fine. Then, all of a sudden, audio will cease to play.

Here are some observations:

When the audio cuts out, iTunes will no longer play. What this means is that the music is not exactly paused, but no progress will occur in the song. If I change Audio to my Mac's Built-In Audio, then it will continue to play.

My CueMix shows the main Output as "Disabled" with no option to Enable it.

Restarting is the only thing that will help. It does not matter which firewire port I use. This problem happens on any port.

MOTU has not been very helpful with this matter. Anyone have any idea how to fix this?
Thanks
