Problems with a shared external USB drive

I have setup an external USB drive on my iMac 10.6 and use it for Time Machine backup. When I try to access this drive over my wireless network from my PowerBook 10.5.8 for TM backup, I can only see the drive under Shared as a Folder, not a drive icon. It is not available for the PB's TM app. This is a HP 1 TB drive formatted in 1 partition MacOS Extended journaled GUID .... and it works as a backup drive for the desktop 10.6 TM.
The very same thing happens if I connect this USB drive to my Airport Extreme only both the PB and the iMac see the drive as a folder and neither can use the drive for a TM backup.
So, how can I see the drive as a drive icon from the PB and have it available for TM backup over the network?

Do not attempt to back up that way -- it's "iffy" and +*not supported by Apple.+*
It sounds like you've missed a step in the setup. See #22 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
Be sure to note the advice there to partition the drive, so each Mac has it's own, exclusive space.

Problems copying files to external USB drive

I am trying to copy my Pictures folder to an external drive, but I get the error below. I have checked permissions and that does not seem to be the problem. None of the files are open and neither is iPhoto, Photoshop Elements are any other program that would try to access the files. Can anybody help?
"One or more items can't be copied. Do you want to skip them and copy the remaing items?"
Thanks.

So have you clicked through to copy them to see if any are missing? It may only indicate that there are some invisibles it cannot copy.

Suddenly can't share external USB drive

I have all of my iTunes music on an external USB drive called 'iTunes_Drive', attached to my G5 iMac in the basement. For a long time, my wife would just run iTunes on the G4 iMac in the living room and play music through the Shared Libraries feature. However, this is slow to start up each day, so I came up with the idea of just sharing the external drive, and having her maintain her own library based on the music in the shared drive.
Just today, it became impossible to access this shared drive from the G4. Interestingly, when I shared a FireWire external drive with the same settings, then that drive WAS visible as an available shared folder when connecting from the G4.
Rebooting both computers hasn't changed anything. The firewall on the G5 is turned off, and it's allowing AFP, SMB and FTP sharing of the drive. The G4 CAN mount the iTunes_Drive using SMB, but iTunes doesn't recognize it as the same drive (possibly because under SMB it's called "ITUNES_DRIVE:" whereas in AFP it's "iTunes_Drive").
Is there something new in security which is preventing AFP sharing of external USB drives? Neither googling nor searching through this forum has turned up anything that helps me.
I should note that the G5 is running Leopard 10.5.1, and the G4 is running Tiger 10.4.11, and I just ran Software Update on both computers last night, with the attendant reboots this morning.

I've experienced a similar problem with my two external hard drives connected to my AirPort Extreme Base. Since installing yesterday's security update, I can no longer see either hard drive. From my Shared folder in Finder, it's now constantly in 'Connecting' mode. I've tried rebooting and checking everything to no avail.
Any help out there would be appreciated.

[SOLVED] Problem with external USB drive started yesterday

My system freezes for about 65 seconds at the login screen. After 65 seconds, I can login and everything is normal afterwards.
I discovered that I can eliminate the freeze by disconnecting the external USB drive from the PC. Here are the error messages from kernel.log when the drive is connected:
Oct 15 23:10:14 localhost kernel: [ 17.035091] usb 1-1.3: device descriptor read/64, error -110
Oct 15 23:10:29 localhost kernel: [ 32.155955] usb 1-1.3: device descriptor read/64, error -110
Oct 15 23:10:29 localhost kernel: [ 32.325394] usb 1-1.3: new high speed USB device number 4 using ehci_hcd
Oct 15 23:10:31 localhost kernel: [ 34.045126] MediaState is connected
There is supposed to be a kernel boot option (irqpoll) to prevent this from occurring. However, that option seems to no longer work for kernels after 2.6.39. If I try using it with Arch, the system will not boot, saying all the CPU's failed.
I also don't understand why this just started happening yesterday, as the USB drive has been connected to the PC longer than I've been using Arch. Also, my kernel has not been updated since I installed Arch on Oct 8.
Does anyone know another fix or workaround for this problem?
Thanks,
Tim

Problem solved
I feel stupid, but I also feel better. I turned off the PC, disconnected the power from the USB drive for about 15 seconds, reconnected the power, rebooted, removed the irqpoll kernel option, and Ubuntu started, perfectly. I need to learn that the USB drive just goes freaky sometimes and remember to do this. But, this is only the second time I've had to do this in months of use.

Cannot access shared external hard drive with other mac accounts

I cannot access a shared external hard drive with other mac accounts (all accounts are on the same macbook Pro). The shared external drive is shared via time capsule and is connected (of course) in USB. I see well this external hard drive as a shared disk with my main account. Yes shared option has been activated with the Airport Utility .. but when I open other account these othe accounts can see the external drive but cannot access to its content that is flagged with a no way sign. Strangely enough when I close my main account and start opening a new session with one of the other account then fine I can access the external hard drive and its content .. BUT then it is from my main account than I cannot access its content the no way sign showing ..
Looks like only one account at a time can access the content of this SHARED external hard drive .. any one as an idea on how to really make it a shared hard drive so that all accounts on the same mac can also access it ? I am at my wit ends on this case. THANKS ..

Results of my enquiries at Apple Genius Bar .. the guys found the problem interesting. They've been unable to provide a fix neither to give any explanation as to the reason why. To be fair I was not much impressed by the technical level demonstrated ..
In the mean time I have found that if account no.1 can see the shared external drive content and in such case account no.2 (same Mac computer) cannot see its content (only the external HD with a no way sign) this account no.2 can UNMOUNT (by ejecting) this external HD from account 1 and then remount it (just clicking on the TC shared part in a finder window) and .. see and access its content ; whilst account no.1 cannot see its content anylonger. Unless it unmounts the shared external HD and remount it .. then account no.2 can see its content anylonger. This can goes on an on.
So eventually YES the TC can allow to share a USB external drive between several accounts and a same Mac .. BUT this require to unmount and remount EACH time the external drive is accessed from a "no.2 account". So OK to share files with seldom access but not practical in case of frequent access needed.
I just I have now to figure how iTunes can automatically unmount and remount a shared external HD when it needs to access one of this shared HD content from on time account no.1 and then next time from account no.2. May be I am asking too much ..

Sharing External USB & Firewire Hard Drives?

I have a MacBook Pro and a Mac Mini. The Mac Mini has an external firewire and external USB drive attached. I can log into my Mac Mini from my Macbook Pro using file sharing. The problem is I can not connect to the exrternal drives. They are not showing up as options to mount. I could swear I was able to do this before with my old G5. How can I set this up so when I connect to the mac mini I can access the external drives?
PLEASE PLEASE PLEASE help me with this problem!

Well, to be more specific:
Sharepoints allows simple management of the network sharing of folders.
Mac uses Samba as a 'universal' sharing protocol. (Samba, or SMB, is a wel-estabished protocol).
Manual management of the Samba configuration file is possible, but can be tricky. It's a file hidden from easy accessibility within the /private directory structure.
Sharepoints simply allows easy, graphical interface to that file. Sharing of certain folders (and in this case...a USB or Firewire drive), user-access permissions, and other cool stuff...is all handled in a very simple window.
(however, you don't NEED it)
You can download it to your existing machine, and take a look, practice.
It will much clearer once you have a 2cnd Mac. Until this it will all seem like theory.

EXTERNAL USB Drive will not open with Snow Leopard

External USB drive will open with SL. The drive icon appears on the desktop. When I click on it, Error message, "The alias USB Drive can't be opened because the original item can't be found." When I click on "Fix Alias", a window pops up and shows the usb drive in a list but does not respond when I click on it. I then tried disk utility and tested the disk and it tested OK. The drive still will not open. This problem started after I installed Snow Leopard. Need Help.

The same error is produced when I try to mount a smb share.
I select the "connect to server" (cmd-K). Input the share info "smb://<user>@<server>/<share_path>
At the auth prompt, I input my credentials.
The error pops up, same as original poster.

FSCK and reboot issues with external USB drive

I'm having an issue with an external USB hard drive I'm using. I've always had issues with this drive cause my reboot to "freeze" when it's mounted. Basically the system message with be sent out, but it doesn't actually proceed with the reboot. No switch to init 6 or anything, but the shutdown process is still active. I can continue to use the computer as usual, but I can't cancel the existing shutdown or try to enter init level 6 by hand. So I just got around this by unmounting the drive before I shutdown. However, lately when I try to unmount the drive I get an error saying that the drive is in use and I should check to see what processes are using it by runing lsof or fuser.
Yesterday I tried copying dsome files from the drive but there wasn't and activity on the drive. cp didn't report any errors though, it just sat there and did nothing. I tried running fsck on the drive, but didn't get much farther. I'll see some activity on the drive for about a second, then all activity stops and fsck just sits there. When I try to kill fsck, it won't. Even with a kill -9.
I'm really confused as to what is going on. Has anyone else had this problem? Anyone have any ideas what could be causing all this or what I can do to stop this? Thanks in advance!

Press the reset button on the device. It is located between the USB and power ports. Make sure to take-out the external USB drive before you reset the device. Or you can also restore the defaults by accessing the Administration tab > Factory Defaults sub-tab in the router’s web-based setup page.

Performance Issues with 10.6.7 and External USB Drives

I've had a few performance issues come up with the latest 10.6.7 that seem to be related to external USB drives. I have a 2TB USB drive tha I have my iMovie content on this drive and after 10.6.7 update, iMovie is almost unusable. Finder even seems slow when browsing files on this drive as well. It seems like any access to the drive is delayed in all applications. Before the update, the performance was acceptable, but now it almost unusable. Most of the files on this drive are large dv files.
Anyone else experience this?

How can I do backups on internal disc while sharing an external USB drive?

Hi,
On my Airport Utility there are two lines: "Time Capsule Disc", and below (indented) "Data".
(When I plug an external USB drive I can see it in this window as well)
Clicking (selecting) the first line, on the right hand side I can see the disc details (name, capacity and SMART Status (Verified)), and two buttons: Compress and Erase (I don't know if these are the words used on the english version mine is spanish).
Clicking on the second line (Data) I can see the Name "Data", capacity, used and available sizes and number of users connected.
First question:
Why Time Machine can't see the "Data" volume if I untick the "Share files" checkbox?
Second question:
Moreover, I've got a USB External Drive attached to my Time Capsule, so I have to have the "Share Files" checkbox ON, this makes my USB disc (fat32) available to my Windows computers but ALSO the "Data" volume can be seen from Windows. If there is any attempt to assign a Windows drive letter to the "Data" volume, next time Time machine wants to do a backup I'm getting a "disc wrong or missing, check credentials (or something similar)".
In summary, what I'm trying to do is Time Machine backups to the internal Time Capsule disc (making that disc unavailable/invisible to any other computer in my network) while sharing a USB external drive attached to Time Capsule.
Advice, please!

Yes you can go to > Music > iTunes folder and copy the whole iTunes folder and drag the folder to your external and then on the new Mac click and highlight the iTunes folder and then in iTunes click on the button at the top (add folder to library) and you should see all your songs transfer from the external to the Mac and all songs start filling up in your iTunes library on the Mac.
This is the easiest method all songs and other media such as songs, movies, apps will be transferred over however you may not be able to keep ratings & last played counts using this method.
To keep all metadata including ratings & play count use the Apple method exclusively for this if you have to have your metadata, play counts and ratings saved.
I used scenario one above because it one of the simplest methods and I was just satisfied enough just to transfer all media over.

Is it possible to format an external USB drive with XFS or EXT3 ?

Greetings all.
I am running a 2,8Ghz 8x core with 6Gb ram. I have a NAS, (Buffalo Pro Duo Linkstation) which has a built in linux which saves data using XFS (I think). It has a built in backup routine, but the drive it backs up to MUST be in XFS or EXT3 (Fat 32 works but it drops all files over 2GB ;( ... ) So - here's my question:
How can I format the external USB drive (A seagate freeagent) in XFS or EXT3 so that it can run on my Buffalo? My preference is to use a GUI mac program (does one exist?) or to use a command line UNIX command (FSK? - but then, how????). I could also use (GASP!) a windows utility on parallels, or even install a linux distro via parallels. But it should be easy I hope...
Looking forward to any ideas/thoughts, tips, etc.
thanks and best to all from Berlin,
Jason

Download a "Live CD" (one you can boot of into running copy of Linux without having to install anything; for example, [OpenSUSE Live CD|http://download.opensuse.org/distribution/11.0/iso/cd/openSUSE-11.0-GNOME-Li veCD-x86_64.iso]).
Use OS X' Disk Utility to burn it to a CD.
Insert the CD you just burned (if it ejected afterwards), and then restart your Mac.
Hold down the 'C' key on the keyboard as the Mac boots, and it should switch to booting off the CD. Once the CD starts loading, you can let go. It will take a couple of minutes, but it will eventually boot into Linux.
Attach your USB drive.
Run gparted (you need to search the menus for it, it's under system administration, I think -- or you can open up a terminal window and simply type 'gparted').
Find your disk (/dev/sdb or /dev/sda) and partition and format it using the filesystem you want.
When done, restart the computer. You'll boot back into Mac OS X and have an EXT2/EXT3/XFS formatted external drive (that OS X won't recognize, by the way).

PowerBook G4 external USB drive problem

I've got a 12" Powerbook G4.
All of the following operations were performed with the laptop plugged into the power adapter.
Today I connected a Bytecc external USB drive model 7050 containing a Maxtor 6 L060J3 60 GB and started backing up my main drive and moving some movie projects to it.
I initialized the drive using the Disk Utility.
I used Finder to copy almost 55 GB of data to the initialized drive.
I attemped to use the 'eject' icon in finder to disconnect the drive so that I could remove power and move some things around my desk. The drive did not 'eject'.
I disconnected the USB cable from the G4 and got the warning message from OSX.
I powered down the drive and moved things around then attempted to reconnect the USB drive.
I repeatedly got a "Volume not found" error with the correct name of the drive. The drive still appeard in the finder pane.
I attempted to verify and repair the disk using the Disk Utility, which still recognized the disk, but was still getting the "Volume not found" error when I attemtped to access the drive using Finder.
I used the disk utility to verify and repair the G4 system disk, at which time the USB drive dissapeared from the Finder window.
Now, attempts to reconnect the drive, do not show the drive as present in the Finder window, yet:
- when I disconnect the drive, I get a warning about stopping a device
- the drive still appears in the list of drives in the disk utlity app.
Any ideas on how I can get this drive to work again? I spent a lot of time dumping video into iMovie from my digital camcorder and I'd like to avoid reformatting the drive.
P.S. What is the correct way to shutdown and remove an external drive?
Thanks,
Larry Ice
12" Powerbook G4 Mac OS X (10.4.6)

The proper way to shut down and remove the drive is to unmount it (drag it to the trash) and then power down the drive before you unplug the usb cable. If the eject icon didn't work you should have tried dragging to the trash. If that didn't work go to Disk Utility and unmount from there. if that didn't work try Repairing the drive from Disk Utility. I would not have pulled the usb cable as you did.

Sharing External HFS Drives

I have a MacBook Pro and a Mac Mini. The Mac Mini have external firewire and external USB drives that are HFS formated attached. I can log into my Mac Mini from my Macbook Pro using file sharing. The problem is I can not connect to the HFS formated external drives. They are not showing up as options to mount. How can I set this up so when I connect to the Mac Mini I can access the external drives?
I could use any help anyone has for this problem.
Thanks

You need to manually configure which directories to share. By default only users home directories and certain public directories are shared.
Unless you're familiar with configuring the sharing daemons, your best bet is to get a copy of SharePoints which puts a nice GUI on the process.
