Why Airport USB disk is that slow?

I'm using Airport Extreme at 802.11n to connect to the Internet and a 400GB USB 2.0 disk. I wonder why the transfer is SO SLOW (ussually 2.0 MB/s and peak of 5 MB/s).
For other people is this speed too?

I got so frustrated with the slow speed on mine that I actually unplugged it from the APEBS and plugged directly into my MBP. Made me "very very angry indeed"! I didn't have this problem under Tiger.

USB Disks Drives that don't show up in AEBS

USB Disks Drives that down show up in AEBS
NOTE: This thread is about drives that are not seen / recognized by the Apple Airport Express Base Station 802.11n (AEBS) when attached to the USB port of the AEBS. Drives that are not seen by the computer, but are seen by the AEBS should go in another thread.
I know some of us are having problems getting out USB hard drives to work with the AEBS. If you launch the airport utility and manage your AEBS but your drive does NOT show up under the disk tab.
I know it’s not a formatting problem so I assume this is a hardware related issue. There has to be a common flaw in out drives
I have a Seagate Momentous 7200.3 installed in a generic USB enclosure. I figure the problem is because of…
1) A Generic Chipset
2) It’s USB Powered (not externally powered)
By going into the System Profiler (Apple • About this Mac • more info) and if I click on the drive name under USB I get the following details
1) It draws 500 mA
2) Transfers 480 Mb/s
3) Product ID 0x6390
4) Vendor ID 0x058f
Right now it’s formatted using a Journaled HFS+ file system
It would be great if other users of the AEBS could report information about any drives that do not show up in the AEBS.
Thanks
Mac mini 1.83 Mac OS X (10.4.9)

Neither my LaCie 500 Gb or my Crossfire 250 Gb (both externally powered) show up in the AEBSn. Both of them appeared in the AEBSn for a couple of weeks. The only change I can think of is that I upgraded to 10.4.9.
I've done all the resets, but the AEBSn just cannot identify them.
I put a call into AppleCare this evening, but the Level 1 guy knew less than I did. I'm waiting for a callback from AppleCare. If I hear anything I'll put it in the forum.
My guess from the HD/AEBSn problems in the forums here is that there is a bug, which with time our good friends at Apple will iron out.
Shame, because I bought the AEBSn because of Airdisk, but I'm bowled over by its speed and range.

Airport USB Disk - access from PC?

I have set up my USB disk in my Airport utility, trying all three options (accounts, disk password, and device password). I cannot find it in Windows Explorer or Internet Explorer to access it.
What is the trick?
Thanks,

There are a number of posts related to accessing AirPort Disks from Windows Vista / 7 PCs. Two potential solutions being forwarded are: 1) Changing the LAN Manager authentication level, and/or 2) Disabling the Windows Search feature.
To change the LAN Manager authentication level:
From the Windows Vista / 7 desktop, click Start
Search for: security
Click 'Local Security Policy'
Goto Local Policies > Security Options
Under Policy, double-click 'Network security: LAN Manager authentication level'
Change level to: Send LM & NTLM responses
Under Policy, double-click 'Network security: Minimum session security for NTLM SSP based (including RPC) clients'
De-select 'Require 128-bit encryption'
Click OK
To disable Windows Search:
Start > Control Panel > Programs > Programs & Features
On the right-hand side, click "Turn Windows features on/off"
Scroll down, and de-select "Windows Search".
Press OK, close all windows and restart.
A third "solution," that has worked for me, is verify that both the AirPort base station and the Win7 PC are using the exact same Workgroup Name. In my case, I use "WORKGROUP" (without the quote marks) for this name.
From the AirPort Utility, you would enter this value on the Disks > File Sharing tab.
On Win7, Start > Control Panel > System and Security > System > Change Settings > Change > Workgroup

Using the airport usb disk with playstation3...

anyone know how i can get my PS3 to see the USB disk hooked up to my AE, and use it as a media share?
I have a wireless-n AE, with a 250GB USB drive hooked up, and also a WD Mybook world edition 1TB server on a ethernet connection.
all the macs in my house see the drives just fine, but everytime i search for a media share on the PS3, it says 'no media shares found'.
i'm sure its a PS3 issue, but i was just wondering if anyone here has any experience with it, as i'm a complete noob when it comes to networking.
thanks.

a) WEP WPA password, ive never set one up for the airport, where do i find out what this password is for my PC?
You will set up wireless security (WEP or WPA) on the AirPort Express Base Station (AX)..using the AirPort Admin Utility, which is part of AirPort for Windows.
b) Everytime I run the Airport Express Assistant it gives me an error message saying "Windows is not the current network manager...please change Windows to the default", I dont know why I get this error and I assume windows is the one managing the networks I use.
Your PC has wireless capability...correct? The AirPort Setup Assistant requires a wireless connection to the AX.
c) I can connect to the airport through windows, but when in the Airport Management Utility it does not detect the Airport
Connect your PC directly, using an Ethernet cable, to the Ethernet port of the AX, and then run the AirPort Admin Utility to configure it.
d) After all this, will Windows and iTunes allow you to stream music thru the Airport Express, like it does on my mac with itunes???
Yes, you will be able to stream iTunes from your PC to the AX, either wired or wirelessly.

Inconsistent Airport USB disk mounting patterns

I have two Airport Extreme networks -- one at home and one in my office at work. I access both networks with a MacBook. Fine so far.
I also have an Iomega USB disk attached to the APE at home and an identical disk attached to my APE at work. The disk at home mounts nicely on my desktop. However, the disk at school does not mount. Connection proceeds to the point where I type in the password, but it does not mount, and I get the volume "__" could not be mounted message. This message appears regardless of which user account I work.
So, the Airport disk mounts fine at home but does not mount at my office. I've spent several hours deleting preference files, mucking around with the Airport Utility, etc. No go. Restarting the APE at work sometimes gives short-lived success, but it does not seem to last.
Any suggestions?

Okay, after reading several other discussion posts, the best workaround I've been able to find is to mount the Airport Disk through the Connect to Server menu. You'll need to know the IP address of your AirPort. It's probably either 10.0.1.1 or something like 192.168.0.1 -- you can find it by running AirPort Utility from the Utilities folder. Just click on your AirPort base station on the left side and the utility should say what the IP address of your base station is. (You can then quit AirPort Utility.)
Then press cmd-K, OR from the Finder click on the Go menu and then select Connect to Server...
In the "Server Address" box, type smb://AEBS-IP-adress/Volume-name
For example, in my setup, I connect to smb://10.0.1.1/Iomega because my AirPort Extreme Base Station has an IP address of 10.0.1.1 and the name of the drive I have connected to my AEBS is called "Iomega" The volume should now mount and show up in the Toolbar of any Finder window. It does NOT show up as a separate volume on my desktop, but your mileage may vary.
This has worked for me each time I've tried it and is much more reliable than trying to select my AEBS from the "Shared" option in the Toolbar of the Finder window.
BTW: If you will be doing this regularly, you may want to go back to the Connect to Server menu and click the + button to add it as one of your favorite servers.

Airport Extreme with Airport USB Disk issues - Dont give up just yet...

Just a heads up for anyone who is having issues with accessing an Airport disk with the latest firmware.
After calling Apple support as i was convinced my AEBS was faulty, i have since discovered that if and HFS+ disk cannot be varified and repaired successfully in Disk Utility, it would lock up my AEBS totally. My wireless would drop out and nothing would work any longer untill I turned the power off and on again.
I was able to correct the issue with the USB HDD by booting with the Leopard CD and using Disk Utility in Mac OS X setup. Trying the same thing when booting from the Macbook HDD would result in a 'failed to unmount' error.
Before anyone has a fit and trys to return their AEBS with a similar issue i suggest trying the above or another USB HDD. It just might save you the $49 that i paid as a result of being out of the 90 days of support on my AEBS and Macbook.
FYI, contrary to the technical requirements i was sent by the Apple service agent i spoke with, my Airport Disk IS working with 2 partitions. 1 HFS+ and the other a Windows partiton (i cant remember if its FAT32 or NTFS. My HDD is at home)
I have a collegue at work who was having similar issues with a FAT32 USB HDD on his AEBS but we have just discovered that the HFS+ HDD that i used to test my AEBS with, worked fine on his also. We are yet to find out if his HDD is faulty at this stage. Ill keep you all posted on what we find.
SO, at this stage it would be resonable to say that the AEBS doesnt handle corrupted HDD's very well. (IE it totally locks up and the wireless drops out)

That used to be a problem on 7.2.x. Now 7.3.1 can fix some minor disk problems (such as disk not unmounted correctly).
Since I upgraded to 7.3.1, I haven't once taken my USB hard drive out to be repaired on my Mac.

Disk Utility to Airport USB disk?

It looks like the answer is no, but I'm mildly surprised that Apple didn't make this more Apple-like
Just checking to see if one can do any "Disk Utility" type of access (Erase, repair, etc) to a USB HD off the AEBS (I have the gigabit version), or if you have to connect directly to your Mac for that.
Thanks,
Mike

You must connect the drive directly to your Mac to get those abilities.

USB Disk access "Extremely" Slow

I am unable to use my network disk essentially because the disk access write/read times are SO SLOW...I am better off running backups by connecting my disk directly to the compter. Does anyone else have this problem?
It took 5 Minutes to read my Music directory; connected directly via the same cable it takes seconds.
What gives?
Any help would be appreciated.

I got my AE and Seagate FreeAgent Pro hard drive
yesturday and I have the exact same problem.
If I hook up the drive to the computer directly it is
very very fast.
If I hook it up to the AE it takes about 2 hours to
move a couple fils totaling 2 gigs over ETHERNET!
If I transfer the same files over the same network
between 2 computers the speed is much much faster.
Is this normal or some nasty firmware bug. It almost
feels like the AE is using USB 1.0 for some reason.
You guys are funny. How about checking out the specs of USB 2.0 and 802.11g/n?
Go here:
http://en.wikipedia.org/wiki/802.11g#802.11g
and here:
http://en.wikipedia.org/wiki/USB_2.0
Firewire vs. USB tests are here:
http://www.g4tv.com/techtvvault/features/39129/USB20_Versus_FireWirepg3.html
802.11g:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
June 2003 2.4 GHz 19 Mbit/s 54 Mbit/s ~35 meters
802.11n:
Release Date Op. Frequency Data Rate (Typ) Data Rate (Max) Range (Indoor)
Mid 2008 5 GHz and/or 2.4 GHz 74 Mbit/s 248 Mbit/s (2 stream) ~70 meters
Bottom line: 802.11n typical is 74Mbps, 802.11g typical is 19Mbps. USB 2.0 typical is 50Mbps.
On the average, you should expect your speed to drop by over 50% when connecting the USB drive to AESB using an 802.11g device. If your device is 802.11n, then you should have pretty much similar performance.
Now, if you increase the distance from your base station, or you put walls in between, the performance of 802.11g will go down "dramatically", all the way to 2-3Mbps, easy. Not so for 802.11n, which behaves much better at longer distances.

PS3 and Airport USB Disk

I'd really like to get my PS3 to connect to the USB drive attached to my Airport.. but not sure if it's going to be possible. Does anyone have any more info, or know a way to get it to work?
Apparently:
+PS3 uses HDNA (uPnP)+
+TC uses Bonjour (mDNS)+
http://discussions.apple.com/thread.jspa?messageID=6568952&#6568952
But perhaps there is still a way to get them to work together..?

I have a 500 GB WD connected to my AE and it's FAT formatted (I think this is the only format PS3 will read). I use Nullriver's MediaLink and once it shows up as a Shared drive on my G5 the PS3 can access it as well. I don't believe it can access this drive if the G5 is sleeping or turned off. But the advantage is that I can put MediaLink on my laptop as well and "serve" music and video from the shared drive. I haven't tried it yet, but it should work.

Do I Need To Remount/Keep Mounted Airport USB Disk?

I have a Lacie HD connect to airport extreme and have mounted it on my desktop, designated it as m y Time Machine destination, and am in the process of the first 130gb back up. My question: do I have to have the Lacie mounted, on my desktop, for TM to find it/work in subsequent back up?
Thanks.

yes

Getting random "USB Disk unplugged" entries in Airport log

Hey all
I have an Airport Extreme with an usb disk attached that I use for backup, fileserver and so on. Most of the time the setup is stable but sometimes the connection to the usb mounted disk fails. These failures seems to appear at random but every time I can se an entry in the Airport Extreme log as shown below. There can be days between these failures or sometimes hours. When it happens I cannot mount the disk again by myself in finder, getting the message: no volumes are availiable for mounting. To get the disk mounted again I have to force an update of the airport. I use AFP protocol, using SMB makes no difference. I have tried a more detailed log level hoping that the reason for unplugging the disk would be revealed but with no luck.
The disk is a Seagate 500GB, filesystem is HFS+.
Can anyone recognize this problem?
Log message:
Aug 16 13:56:12 Severity:5 Disk sd0 (ST350063 0AS 3.AA) unplugged.

Same issue here. I think it may have something to do with a bad usb HDD attached to the airport extreme.
I have 3 HDD plugged into the Airport extreme - only one of them shuts down the airport extreme.
Perhaps if you have one handy you could try a new drive, see if that works.

Airport Extreme doesn't see my USB disk

Hello,
i have changed the usb disk (full) that i connected to my airport extreme. I replace it by a new one (MEM UP, 2 To), formatted in mac os extended.
This new disk is mounted by the Mac but when i connected it on the Airport, the Airport doesn't see it : "no disk detected".
There isn't hub, it is connected directly.
Have you got an idea ?
Thanks,
Rudy

The USB port on the AirPort Extreme is under powered....and your new hard drive may require a bit more current than the old one.
It is always a good idea to use a powered USB hub with the AirPort Extreme whenever you are using a hard drive....even if the hard drive has its own power supply.
A powered USB hub may not solve your issue, but there is also a chance that it will. Might be worth a try.

AirDisk - cannot see the USB disk in Finder

Dear all,
I just brought the Airport Extreme Base Station with the purpose to use an external HD shared with all my Macs
The AEBS works quite well, but I’m not able to see the USB disk in the Finder…
In the airport utility I can easily see that AEBS recognize the USB disk, and that that disk is connected, and I’m sure that that disk works well and that is formatted as Mac OS Extended
Even after checking the huge problem affecting this firmware release (mine is 7.2.1) and following all of the suggestion posted by the community (connect, disconnect, restart, pray for an update) I cannot even see the disk in Finder…
I’ve heard of people that cannot mount or access or disconnect… but I cannot really see the disk itself…
Any suggestion?
Thank you very much in advance

Hi!
I got mine working now! As the problem started to seem like an authentication issue (disk was in "connecting" mode for eternity) I started to think that the problem might be actually in MacBook Pro/Leopard end of the system rather than in the Airport Extreme or AirDisk. I tried then to create a new account and "account preferences" application got all stuck - was not possible even to force quit. I then forced the MacBook to shut down with the power button and rebooted. A miracle happened! Now I can see the folders of the AirDisk and can copy there. Next I will test whether I also have the same problem that backup with Leopard to AirDisk is extremely (read prohibitive) slow.
I hope this simple trick helps others as well
I am keenly waiting for the next Leopard update... have to say that being used to great Apple user experience this has been a major disappointment. It seems that Apple is leaving us alone with our problems. They should facilitate somehow these forums and pull together FAQ's as suggested by many.

I can't see the files on my USB disk

I know there are about 250 million threads about airport USB disk problems, but I can't see one with my specific drama.
I can connect, see the drive (its a LaCie 250GB) and move stuff to it via the airport. The problem is that I cant see the files once they are on the LaCie. The finder window will start to show each folder but after about 1 second all the folders dissapear and the finder says "0 items, 91.38 GB available".
Obviously the computer is reading the drive as it knows how much space is on there, and it can write to the drive - it just wont display the folders. If I connect using a USB cable then all is well, so its just the ***** airport!
Someone please help, I'm going mad!

The disk sharing utility creates separate folders which are not visible when connected to the AEBS, but are when directly connected via USB to your computer:
"Shared" > for all mainly shared files and folders
"[Username]" > for all user related files and folders when you use account to access your disks through the AEBS via Airport.
So if you first connect your disk directly to your PC, make sure you copy your files to the "Shared" directory (and not directly in the root), and if you did not connect the disk to the AEBS before, or the "Shared" directory does not exist, make this folder yourself.
Goodluck!

My iMac came with mountain Lion preinstalled. I wish to make a Bootable USB Disk. I find that I am not allowed to d/load Mountain Lion from the App Store. I wish to make a purchase. Why can't I?
