Cannot mount USB Hard Drive (750GB LaCie Desktop Hard Disk USB2 K)

I recently purchased a 750GB LaCie Desktop Hard Disk USB2 K, and used it to back-up my NAS (Ready NAS NV+). Now I want to transfer some of this data on the Lacie at a separate location to a Time Capsule, via my MacBook. When I insert the USB cable into TC it seems to recognize the disk, but I cannot see the contents (I have a separate post on this).
WHen I insert the USB cable into my MacBook, I get the message:
"The Disk you inserted was not readable by this computer."
I (THOUGHT) I had formatted the disc as ext3, but do not recall (and cannot access my notes remotely). Is there anyway I can use disk utility to check the formatting, or does the message above give the game away?
Any thoughts appreciated!

I did not think that EXT3 support was built into OS X. There are various utilities around but I do not know how well they work and they would only be useful for the Macbook.

Cannot Access USB Hard Disk

I have a USB hub connected to my airport with a printer and USB hard disk attached. I can see in manual setup in AirPort utility that both the printer and the hard disk are set up and connected. The printer prints wirelessly.
My problem is that I cannot find the hard disk on my computer in order to take and put in files. Where is the hard disk located???

In the Airport Utility /Disks/File Sharing make sure 'Enable file sharing' is checked. Select your choice for access (Secure Shared Disks).
Airport Disk Utility: I have enabled 'Automatically discover AirPort Disks' as well as 'Show Airport Disks in the menu bar'. My action for the Airport is 'Connect with Password'.
More often than not every disk I add to the hub (which is attached to the base station), shows up immediately. When it doesn't, I simply use the menu bar icon, click on the airport name and click 'OK' once the disk availability box appears. My oresent setup is to remember the password in my keychain.
Note: since updating the firmware as well as Airport application, I have had no issues with hard drive access or, in particular, printer access.

Cannot see my shared USB hard disk's connected on my Mac-mini on my Macbook

As you all can see, I'm a Mac user since 1989, i've don't like working on a windows-computer.
But i've got a problem since I'm using Mac os X 10.5. If i try to make a connection with my Macbook pro to my Mac-mini (my Mac-mini has two USB hard disks) i cannot select the USB hard disks. But my WIDOWS computer has no problem to approche these disks???? Can anyone help me????

Hi WillemH777-NL and welcome to the discussion forums.
On the MacMini open system preferences-->sharing
then select 'File Sharing' from the Service column. Then under Shared Folders make sure your 2 usb drives are listed, if not click the + sign and add them.
then click the 'options' button
make sure Share files and folders using AFP is checked
make sure Share file and folders using SMB is checked
Then switch on the names of the users and the mac can use the smb service.
then click Done
Now see if you can access the mini's sharepoints.

Arch: Install to & run from External USB Hard Disk Drive (HDD)

I wanted to play with ArchLinux 2009.02, but replacing the existing Debian-Lenny on the laptop's HDD wasn't an option. So I experimented with installing Arch on an external USB Hard Disk Drive.
I have tried to make this "newbie-friendly", so I hope the more experienced will forgive the detail.
Materials:
Three year old Dell Inspiron 6000
CPU = 2.0 GHz Pentium
RAM = 2.0 GB
Internal HDD = 80 GB
Internal CD/DVD R/RW
External USB HDD = Freecom FHD-2 Pro 80 GB
Archlinux 2009.02 install CD
Steps to install:
1. I put the Archlinux install CD in the drive and connected the external 80 GB HDD in the USB port.
2. When the Dell laptop was booted, I pressed F2 to enter the BIOS setup. I edited the boot sequence to the following:
Internal CD/DVD
External USB device
Internal HDD
On the Dell, you can also press F12 to select the preferred boot device for that boot.
3. I started the laptop and the Archlinux installation menu came up and I proceeded with installation following the "Official Arch Linux Install Guide" and the "Beginners Guide".
4. Used km to change to UK keyboard layout and then began the installer script (/arch/setup). I was installing from the core CD so I skipped the network steps.
5. HDD preparation.
This was fairly straightforward with two cautions:
(a) Make very sure that the external HDD (sdb) is selected for the operations.
(b) Remember to set the Bootable Flag for the first (/) partition on the HDD.
I chose 20 GB for /, 2 GB for swap and the remainder for /home.
6. The package selection and installation was fairly straightforward.
7. Configuration of System
This was section was straightforward with one warning:
USB had to be added to the HOOKS in the /etc/mkinitcpio.conf file!
I found this to be essential for my external USB HDD to function as a bootable device. Otherwise I got the same sorts of errors relating to unrecognisable file system types that other people have reported in the forum.
The relevant line from the end of the edited /etc/mkinitcpio.conf file is below:
HOOKS="base udev autodetect pata scsi sata usb filesystems"
8. Installation of GRUB was the other point where caution and/or correction was necessary.
When it asked where GRUB should be installed, I had to select sdb (my external USB HDD) and not any of the particular partitions on sdb. If the root partition sdb1 was selected then the laptop won't boot from the external USB HDD.
The GRUB /boot/grub/menu.lst as written by the installation routine specifies hd(1,0) which doesn't work when you try to reboot from the external USB HDD. When you boot Arch from the external USB HDD, as far as Arch is concerned - at that point in time - the external USB HDD is the first drive in the system. To fix this:
(a) When the Arch boot menu comes up, press e to edit the grub entries.
(b) Change the first line to hd(0,0)
(c) To the end of the kernel line add rootdelay=8
(d) Press b to boot the system with these temporary corrections.
(e) Once your Arch system has booted, edit the /boot/grub/menu.lst to make the above changes permanent.
The relevant portion of my /boot/grub/menu.lst looks like the following:
# (0) Arch Linux
title Arch Linux
root (hd0,0)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/... ro rootdelay=8
initrd /boot/kernel26.img
# (1) Arch Linux
title Arch Linux Fallback
root (hd0,0)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/... ro rootdelay=8
initrd /boot/kernel26-fallback.img
9. The laptop happily and consistently boots Arch Linux from the external USB HDD when it's plugged in before startup/booting.
Running Arch from the external USB HDD seems as quick as running Debian from the internal HDD.
So if there is a performance penalty associated with using an external USB HDD, my wife and I haven't noticed.
In summary, the three essential points to address during installation to an external USB HDD are:
Remember to set the bootable flag for the first partition.
Add USB to the HOOKS for /etc/mkinitcpio.conf file.
Correct the /etc/grub/menu.lst file.
I hope this is helpful.
Ted

Hi Rookie,
As you say, it is worth remembering the rootfstype= option for the kernel line just in case someone still has problems with GRUB after making all the other changes.
I was working with the most recent Arch 2009.2 release.
I only got messages about unrecognisable file system type when I tried booting with the "stock" or "as-installed" GRUB (before I edited /boot/grub/menu.lst). After editing /boot/grub/menu.lst to identify the drive correctly and add rootdelay, GRUB was able to do the rest and everything worked OK without any error messages.
Best wishes,
Ted

HT4889 Migration Assistant to update my new Mountain Lion iMac from an external USB hard disk drive, it is constantly saying that it is "looking for other computers". It doesn't find the external drive. Why is it looking for other computers?

I'm trying to use Migration Assistant to update my new Mountain Lion iMac from an external USB hard disk drive. I told it to look for a drive, yet it is constantly saying that it is "looking for other computers". It doesn't find the external drive ... it just endlessly looks for other computers. Why is it looking for other computers at all, when I told it not to?

Wow, the wording in Migration Assistant is misleading. I've never used it before, so I thought I would try to copy my files from the external drive ... my old iMac died, but I managed to get everything I need off it, using the 'cp' command in single-user mode. So I guess I'll just have to manually copy the files from the external drive to the new machine. I was hoping that Migration Assistant might help somehow, but obviously not.
Thanks for the quick reply!

Can connect to USB Hard Disk via OS X 10.5, but not 10.5?

I'm able to connect to my USB Hard Disk in OS X 10.5 by simply going to "SHARED" in the Finder, but I don't see it anywhere in OS X 10.4. My 10.5 computer is connected to the AirPort Extreme via wireless, my 10.4 computer (it's actually OS X Server 10.4.11 ) is connected via a LAN port.
If I go to the Finder and select "Network" I just see "Servers" which shows the 10.4 system I'm on. I don't see anything about the AirPort Extreme or USB Hard Disk connected to it.
Any ideas on how I can see the USB Hard Disk on OS X Server 10.4.11 connected to the AirPort Extreme via a LAN port?
Thanks!

You should be able to connect to the disk via SMB from your 10.4 computer. Do you know the IP of the airport express base station? If so, use the Go menu from the Finder of the 10.4 machine and use *Connect to Server*. Enter the Server Address as smb://basestation.ip.address.here and click connect. It should present you with a login box and then mount your shares when you provide the correct credentials.
On my airport extreme base station I have File Sharing enabled with base station password, guest access NOT allowed. My credentials are my account username (probably doesn't matter what name you put) and the base station password. It mounts the shared disk perfectly.
Under 10.5, this method (for me anyway) has been MUCH more reliable than using the Airdisk feature. I disabled Airdisk on the client and now I always mount the share using SMB this way. It seems snappier and the problem where I used to get a drive mounted but then be unable to see anything on it has gone away.
If you want it to automount each login (I know this method works on 10.5, can't remember about 10.4) use the *Connect to Server* dialog and enter the Server Address then click the + sign to add the server to your Favorites (the box under the Server Address line.) Then go to your Library folder in your Home directory. You will see the link you put in Favorites stored there as a file. Drag that file into the Login Items list in your user account in the Accounts pane in the System preferences. To see the connection on your desktop you need to make sure you have your Finder Preferences set to show *Connected Servers* on your Desktop. Click on the Finder menu (when you have Finder selected), then Preferences.

ITunes downloads seem to hang when library is on shared USB hard disk

I have a shared USB hard disk on my AirPort Extreme Base Station. I'm able to play music just fine, but when I download a podcast or purchased music from iTunes, the download will start and then hang for a long time. When I quit and tell it to quit downloading in the dialog box, it ignores my choice and won't quit. I'm not even able to force quit iTunes and then can't even shut down my iBook without killing it by holding down the power button.
Is this an issue with transfering the data to the harddrive while airport is also downloading the song? Is there a way to avoid this situation? A setting? Should I be connected to the router directly and not wirelessly?
Please help.

You have to mount your drive each time you want to use it. There is a special Airport Disk Utility to do that. Or you create an alias on your desktop (which you can of course only do once you have connected for the first time).

The finder window for an external USB hard disk suddenly started separating files by time (today, yesterday, etc.) and stopped allowing me to change column width, order, etc. Also the header bar shifted to flat white from gray.

The finder window for an external USB hard disk suddenly started separating files by time (today, yesterday, etc.) and stopped allowing me to change column width, order, etc. Also the header bar shifted to flat white from gray.
All was normal until the icon for the disk stopped showing up on the desktop when I would plug it in. I rebooted the computer, and the disk icon now shows up but this new look to the finder window started as a result. The hard disk does not have this problem when I use it on another Mac running Snow leopard. Also, two other external hard disks that I use on this computer running lion 7.4 still have the normal header bars with columns that can be reordered, etc.
I have tried looking in preferences and other places but have not seen this discussed.

Well duh - I finally figured out that somehow in the View options for the hard drive, the "arrange by" option had been changed to "by date" from "none". Not sure how that happened, I had never used the "view options" menu tem before. Changing "arrange by" back to "none" gets the gray column headers and the collapsible folder icons back.

USB hard disk: operation not permitted how[SOLVED]

hello guys,
I have a usb hard disk with ntfs filesystem. I formatted the drive in windows. Now I want to backup some files on it. Whenever I try to create a folder in it, it says operation not permitted.
How can I change the permission?

And make sure they're not mounted as Read-Only in fstab:
/dev/cdrom /media/cd iso9660 ro,user,noauto,unhide 0 0
/dev/dvd /media/dvd udf ro,user,noauto,unhide 0 0
Works better for disc drives, flash drives occasionally. Hard drives... not so much.

Mac cannot detect external hard disk

My mac is running oin OSX 10.8.5. It cannot detect a hard disk that was originally detected before. This happened after I took out the hard disk a previous I used it without ejecting it properly. thanks!

Have you tested that the MBP USB ports are working?
Have you tried different cables?
Does the HDD work on other macs.
Does the drive appear in Disk Utility?
Have you tried the bare HDD in another enclosure?
Ciao.

Accessing USB hard disks

Hello
I attached a USB hard disk to a workstation with Solaris 9/Sparc. The hard disk does not have a slice table but an x86 partition table so I just want to access the disk using /dev/rdsk/c?t?d?s2 (whole disk) or any equivalent method.
/var/adm/messages shows the following messages:

None of these devices really exist (I get "No such device or address" if I want to access the device).
How can I access a USB hard drive using Solaris?
Martin

Looking at the sources of "OpenSolaris" I found out that opening hard disks without a valid partition table is possible specifying the O_NDELAY flag. This works on Solaris 9, too.
However I found out that my USB hard disk has a hardware problem (does not work with Windows XP) so I cannot test if reading the hard disk works.

Airport extreme doesn´t recognize usb hard disk

After one year of no problems using it, suddenly, the airport utility doesn´t find my usb hard disk connected to an Airport Extreme base station. There is a firmware upgrade to 7.7.1 for this same but unfrequent and rare issue (Apple´s words), though it is only forseen for the new base stations AirPort Extreme 802.11ac and mine is 802.11n.
Has anyone experienced this problem, any solution?
Thanks in advance.

I just called Apple Care and I'm astonished by the answers that the operator gave me :
- he couldn't confirm if Airport Extreme could handle 4 TB disk drive or not. More : he said he cannot obtain this information.
- he advised me to plug on my Aiport Extreme a 4 TB drive borrowed to a friend, or buy a new 4 TB drive in a shop with a 4 days refund policy (to return the drive after the test).
I was very unsatisfied by these answers, arguing to my operator that for me HE is Apple and I expected him to have informations about the specs of Apple products. In the end he advised me to go in a Genius bar with my hard disk. So I asked him a ticket number to give to the Genius bar. He said there was not.
I'm very frustrated by the very low level of information of this call :
- Apple Care didn't confirmed an information that looks correct according to newsgroups or a technical support reseller,
- Apple Care couldn't confirmed the problem was handled by a developpement team at Apple, neither when it could be published.
Another point about Apple Care : when I called Apple Care Yesterday, they said they couldn't handle my request because I haven't the serial number of the Airport Extreme. I said I wanted to confirm the incompatibility for ALL the Airport Extreme, but they argued they must give me a correct answer for my case, especially. Today, after giving the serial number, they said they couldn't answer.
The Apple technical specification of Airport Extreme don't show any limitation in the size of the drive :
http://support.apple.com/kb/SP628?viewlocale=en_US
The MacWay reseller technical support confirmed me that no Aiport station they sell are supporting today 4 TB drives.

Trouble connecting to external USB hard disk through PC

I've had AirPort Extreme 802.11n for a few months which I use to connect to a printer and to share a USB hard disk between my eMac and my thinkpad. For a while everything was working beautifully. The disk showed up on my eMac desktop and in my Windows XP file explorer. Then recently the USB disk stopped connecting at all to either computer even after trying the old remedy of connecting directly to my Mac, dismounting it, and reconnecting. Then today a bunch of updates for the AirPort Utility became available and after updating to 5.3.1 on my eMac the disk shows up on my eMac again. But on my PC here's the situation: the disk appears in the AirPort Utility for Windows (5.3.1) but I can't find it in Windows file explorer. I tried the alternative ways of connecting shown here:
http://docs.info.apple.com/article.html?artnum=306119
but no dice.

Uhmmmmmm, you meant to say the Macbook Air DOES have (2) USB PORTS
GENEDI, yes, you can connect a 2.5" USB external HD to your Mac AIR, ...... done it a 1000 times

USB Hard Disk Question (Format Type)

Hi,
I've bought a 500GB Hard Disk which I'd like to use for editing.
The Hard Disk works fine and I can Log and Transfer small video files ok. The problem occurs when I want to capture large video files. These always seem to error. The same large video files work fine if I capture straight to my iMac's internal Hard Disk.
I think the problem occurs when the video is greater than 4GB. Could this be related to the Format type of the USB Hard Disk?
If so how should I re-format the drive to work with large video files? And how do I do this on a Mac?
Thanks,
Richard.

A USB drive will not cut it for video editing. You will get dropped frames, either when editing or capturing to it. USB transfers data in bursts, not a continuous stream as FireWire does. Wile it might not be happening right now, it will once you start filling it up, having multiple tracks in FCP, etc.
Your drive came preformatted for Windows, as do most of them. The FAT file structure used has an individual file size limit of 4GB.
To reformat as for the Mac OS, use Disk Utility (In the Applications/Utilities folder).
Open Disk Utility.
Select the drive in the column at left.
Click on Erase and choose Mac OS Extended, click the Erase button at bottom right to confirm.
This will of course, destroy all files currently on the drive. Back up first!
For best results, recapture your video again.

Sharing and Securing USB Hard Disks on Your Network

Hello,
For the past year, I had a network created with my Airport Extreme giving me access to a USB Hard Disk. The whole thing was working great until last week. From then, even if I had access to web through my Airport, my network wasn't available anymore. All my settings in the Airport base station are as they where before the bug. My USB disk (LaCie 500g) is fine and running as normal. I have unconnected my base station and USB disk and reconnected them, but still, the computer doesn't give me access to my network and by the same occasion, I don't have access to my external disk.
I need a hand on this problem.
Thanks
