External drive hang (~30 seconds) when new USB drive is plugged in

Hey,
I'm having an issue where I'll be accessing a file on one of my external drives--say playing music through Rhythmbox..I'll plug in a secondary USB drive and the first drive will immediately stop responding for around 30 seconds, before "resetting" and continuing where it left off.  The secondary drive plugged in works fine the whole time.
The following is displayed in dmesg output while the problem occurs:
sr 27:0:0:1: Attached scsi CD-ROM sr1
sr 27:0:0:1: Attached scsi generic sg4 type 5
sd 27:0:0:0: [sdc] Assuming drive cache: write through
scsi 27:0:0:2: Enclosure WD SES Device 1032 PQ: 0 ANSI: 4
scsi 27:0:0:2: Attached scsi generic sg5 type 13
sdc: sdc1
sd 27:0:0:0: [sdc] Assuming drive cache: write through
sd 27:0:0:0: [sdc] Attached SCSI disk
*******Here's where the 30 second hang is*******
usb 1-1: reset high speed USB device using ehci_hcd and address 2
I've tried multiple USB ports (even bought a new case) and the issue persists.
Any ideas would be greatly appreciated.
Thanks!
************************************EDIT************************************
I believe this may have been a kernel bug, as after upgrading to kernel version 2.6.39 I do not seem to have this issue any longer.
Btw, don't buy USB controllers with VIA chipsets if you're going to use *nix...buy NEC chipset controllers.

Yes.  One is a mini Toshiba USB drive with no other options for power.  But even unplugging an iPhone USB cord with NO iPhone attached to it will cause the drive to drop off.  The second USB drive I plugged in today had the same issues.  Basically I have to unmount a drive, then plug in a second device, then remount the drive using disk utility.  Very painful.

  • When I backed up files on my external drive, I inadvertently dragged my itunes library there. Now I can only play songs on my laptop when my external drive is plugged in. How do I get the library back to my computer

    Your drive was used with a PC and formatted NTFS which is proprietary Microsoft format.
    You need to install a third party program that will read the NTFS format.
    There is various software from PARAGON, Tuxera and NTFS-3G
    When you get the data off and have verified it to be good, reformat the drive either HFS+ for Mac use only, or for Mac and PC use then MSDOS (FAT32) for under 4GB files (best) or exFAT (for larger than 4GB files) is proprietary and Microsoft is appling for a patent, which would likely mean OS X won't be allowed to read it anymore without a licensing fee and you'l have to pay another third party software company to read the format, just like NTFS is.
    The less you have to rely upon third party sources to read your drives the better, this way if you have a issue and need to read the drive on another machine you don't need the software, and a internet connection and a credit card and...and...and...

  • Mac Mini is disconnecting all usb drives whenever any new USB device is plugged in.

    I have 10.6.7 on a Mac Mini 2 Ghz Intel Core 2 Duo with 2 GB of ram and a 60 gig hard drive.
    It seems that every time I plug or unplug any USB device, it disconnects all the connected USB drives.  This seems to be something new, but I have not really often used the other USB ports either.  It is very frustrating, as you can imagine.  If I plug one drive in, and then plug another drive in, plugging the second drive it often disconnects the first one.
    But it is not just drives.  I can have only one drive plugged in, and unplug and replug the keyboard, and the USB drive will disconnect.  Then I will get message about how I did not safely disconnect the drive.
    Any help would be great.

  • My PB won't start up when my 2 external drives are plugged in...

    My PB won't start up when my 2 Lacie drives are plugged in. I've used this configuration for the last year and a half with no problems. However it will start up when only one of them is connected. Are they drawing too much power? Why would this happen all of a sudden?
    Thanks for any help here.

    Are these USB or Firewire drives? Do these LaCies have their own power supplies? I've seen plenty of weird stuff happen with LaCies that have dying/marginal power supplies. The power supplies seem to have a reputation.

  • Extremely slow performance when external drives are plugged in.

    I've had lots of freezing issues during startup just recently. After a lot of messing around I removed an iOmega Firewire HDD that was constantly plugged in and the freezing issues have gone. Great! But as I tried to plug it back into my machine once everything had loaded up, the machine became unusably slow.
    I've also tried plugging in USB drives, like my iPhone, camera and memory stick and it has the same effect.
    Anyone else had this same problem or any ideas how to fix it?

    HI,
    *"I've also tried plugging in USB drives, like my iPhone, camera and memory stick and it has the same effect."*
    How much free space on the startup disk? Might be an underlying issue ...
    Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. *Make sure you always have a minimum of 10% to 15% free disk space at all times.*
    If you need to free up space on the startup disk go here.
    http://www.thexlab.com/faqs/freeingspace.html
    If free space is not an issue, then boot from your install disc and run Disk Utility.
    Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.

    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.

  • 1 day old MBP, MASSIVE cpu usage when any USB device is plugged in?!?

    I just purchased a brand new MBP 2.2
    If I plug anything into any of the usb ports my CPU starts clocking and within 10 minutes my system is running it's fans at full speed trying to keep it cool. This can be with no activity AT ALL. I can simply plug a USB thumb drive in and watch as the system gets hotter and hotter!
    Has anyone heard of this and is there a solution. I had planned on booting and external USB drive to run a separate OSX install but this makes that impossible. Any help is greatly appreciated.
    Kalel

    Sorry, it was just taking FOREVER to index my USB drives. One drive is only 120GB and after almost 6 hours it still has 4 hours remaining! For reference it indexed my Firewire drive in about 15 minutes.

  • How do I make Lion wake up when a USB device is plugged in?

    I'm having this issue on a MacBook Air, but I assume it would occur on a MacBook Pro as well.
    What I want to do is to use my MacBook with an external display, and have the lid open so I can use the keyboard/trackpad, but have the MacBook display turned off. There are two obstacles to doing this under Lion:
    1. You can start the laptop in clamshell mode with an external display attached, but opening the lid will make it go out of clamshell mode and turn on the MacBook display, going into dual screen mode.
    2. Since I don't have a wireless keyboard, the trick that I was using in Snow Leopard to wake up my MacBook was to plug in a USB device. This doesn't work anymore in Lion.
    Issue 1 has been resolved by this post:
    https://discussions.apple.com/message/16059565#16059565
    But I'm still looking for a fix to issue 2. Any help would be appreciated!
    PS The solution to issue 1 in the thread above recommends running this command:
    sudo nvram boot-args="iog=0x0"
    I would imagine there's probably some kind of command that will fix issue 2 as well?

    Are there any web interfaces for LKML? I dislike mailinglists; the last one I subscribed to randomly stopped sending messages to me after about an hour. I might try usenet; there are some good-looking groups on there I think.
    Also, I'm sure there has to be a way to do this outside of udev. I mean, if udev can be made to work without using like 30% CPU (which I'd imagine would be what would happen if it polled every 1 second, which is what I'd want it to do), I'll use it, but what about thinking outside the box a little?
    I mean, my first thought was to write a kernel module that responded to dmesg at the kernel level; dmesg doesn't update all that often, and I could run through all the lines I recieve and look for, for example, my PCI ID and a signature telling me if it was added or removed. I just have no idea how to do that.

  • 4 year old PC turns off when new iPod Nano is plugged in

    Hi,
    I have an older PC running Windows XP. I just bought a new 8G iPod Nano. When I attempted to plug it in to my computer for the first time, the computer abruptly turned off (it did not go through the shut down process) and I was unable to turn it back on for several minutes. Now the compuet is back on and appears to be functioning normally. Can anyone help me with this problem? I have not yet tried to plug in the iPod again. Thanks.

    That would be my guess....Here is what Apple has to say about the problem. 
       http://support.apple.com/kb/ts3700
    My guess is that it is a compatibility problem with older or aftermarket ear buds.  My daughter has a 6th generation Nano and does not have this problem but keep in mind she is using the ear buds that came with the 6th Generation Nano.  With the replacement program they are not sending new ear buds.  I just did a test with my daughters 6th Generation Nano using an old set of aftermarket ear buds I had in my desk and I was able to duplicate your issue.  I then used the ear buds from my Iphone 4s and did not have an issue with the Nano going to sleep and the music turning off.

  • Wireless keyboard only works when a USB keyboard is plugged in at the same time.

    I dont understand.  I just bought a Wirless Keyboard a few days ago.  I paired it with my computer and it was recognized and connected and functioned.  However, when I unplugged the USB keyboard that I was using before I bought this keyboard, it was still connected and recognized, but it stopped functioning.  Any ideas?

    Is it an Apple Bluetooth keyboard? You've no doubt checked the batteries are OK, although they shouldn't have gone flat in a few days.
    You could try re-pairing it to see if it sticks, and you may want to make it a favourite, which helped when my Magic Mouse kept losing the BT connection.
    Using the wired keyboard delete the BT keyboard from BT Preferences. Pair it again and when it's (hopefully) connected from the BT prefs window bottom left, click on the 'cog' and select 'Show more options'. You should then get the opportunity to make it a favourite. Disconnect the wired keyboard and fingers-crossed.

  • MBP will not boot if external drive is plugged in

    This has been a long-standing problem with any Mac I've used, but now that I use one on a daily basis it is more of a problem.
    I have an external enclosure with a 500GB SATAII hard drive. I connect it to my MBP via the FW800 port. For some reason if I have the drive plugged in before I am in the OS, the computer will sit on the gray startup screen indefinitely (with no logos at all, simply a gray backdrop). As soon as I do a hard shutdown, unplug the drive, and restart the OS will boot fine. I use Boot Camp with Windows Vista, and since I store many large files the drive is formatted using NTFS. Could this be causing my problem? Any ideas on how to correct this?
    15.4" MacBook Pro 2.4 GHz   Windows Vista  

    Hi Ryan,
    it might be a wild guess, but is it possible, that the external harddisc is a 'Dynamic Drive' and not a 'Basic Drive'?
    While in Vista have a look with the 'Disk Management'
    To access the Disk Management console, right click Computer and select Manage. Under Storage, click Disk Management. The drive configuration of your computer will be displayed in the details pane.
    It seems that OSX has problems even recognizing Dynamic Drives.
    Also is there the possibility, that you use 'Drive Encryption' on the external HD ?
    Regards

  • My USB Ethernet connection drops when another USB device is plugged in?

    I have a MacBook Air (Mac OS X 10.6.7 but it happened with older OS versions, too) and have a few issues with my wired ethernet connection. (through USB Ethernet adapter).
    1. When I have the USB adapter plugged in when I wake the MacBook Air up it won't be recognised (have to plug it in after wake up)
    2. (that is more annoying).When I have the Adapter connected and I plug in another USB device (like a USB stick) into the other slot, my USB EthernetConnection drops! Only once I unplug the adapter and plug it back in it works again.
    Is there maybe a firmware upgrade that should be installed or something??
    Does anybody have an idea???
    Thanks

    Hi, you can upgrade the Firmware for the wrt54g router under the system screen.
    you will find the "upgrade Firmware" tab under the system screen.
    Once the Firmware has been upgraded you can then reset the router by holding and pressing the reset on the back panel for 30seconds. And then reconfigure the router again.

  • Mountain Lion Hangs on Boot when an external cloned drive is attached

    It seems that, for me at least, when I have an external drive, in this case a usb, plugged in on boot up, Mountain Lion just hangs.  This external drive is used as a clone (I use Super Duper). It can hang in one of 2 places; after inputing my password, or when trying to bring up the desktop. It is very consistent as to the hanging.  When the external drive which contains the clone is not attached, it boots fine every time.  I have no problems at all with my other external drives being plugged in at boot. They are just contain data.  Is Mountain Lion getting confused?  Anyone else experience this?

    I am stumped too. The issue is that the 'pmset -g' command does not allow changing the ExternalMedia flag.
    An observation that may be relevant to this topic is as follows: if you unmount the drive (but not physically disconnect it), sleep comes in the specified time. Upon wakeup, however, the drive is mounted again to the desktop. I've noticed this behavior with SD cards, and I assume that HDs should do the same.
    If this is the case, then it may be possible to use ControlPlane (current version is ControlPlane-1.1.4) and create an "about to sleep" situation, which triggers USB disk unmounting. Haven't tried it, but was thinking to (subsequently just gave up and eject my USB  storage manually).
    Hope this helps.

  • [Guide] Install and run Windows 7/8 from an external drive without using bootcamp (works for late 2012 iMacs with 3TB drive)

    This is a copy of a post from my blog, you can also Read it on my blog...
    Introduction
    After I received my new iMac with a 3 TB Fusion Drive, I was disappointed when I realized that Bootcamp was not running on this model and prevented me from installing Windows on it. I wanted to take advantage of the powerful iMac hardware to play games but I couldn't.
    There are a few ways of working around this limitation, but I found most of them quite complex and most of the time they required formatting the internal hard drive or repartitioning it and go for a brand new installation of Mac OS X. I was not comfortable with that.
    But there is another way, and that is to install Windows on an external hard drive, using either USB or Thunderbolt. Personally I used a Lacie Rugged 1 TB drive that has both USB3 and Thunderbolt connectors. Both work very well.
    This guide may interest you if:
    You have an internal hard drive of more than 2TB and you can't run bootcamp at all (like late 2012 iMacs with a 3TB drive)
    You have limited space or you don't want to dedicate disk space on your internal hard disk drive to a Windows installation
    What this guide will make you do:
    It will make you erase all your data from your external USB3/Thunderbolt hard drive
    It will make you install Windows on your external USB3/Thunderbolt hard drive
    It will make you install bootcamp drivers
    What this will not make you do:
    It will not make you modify anything on your internal Mac hard drive
    It will not make you use or install the bootcamp assistant
    It will not activate the Preference Pane for the default boot drive. You have to boot by pressing the ALT key to manually select your boot drive each tome you want to boot Windows.
    What you'll need
    An external hard drive with a USB3 and/or Thunderbolt connector. This drive will be formatted so ensure you saved your files before going further. You can use either an SSD drive or a classic hard drive.
    A Windows 7 or 8 install DVD or ISO (check whether to install 32 or 64 bits versions based on your Bootcamp drivers) and the corresponding Windows serial number.
    One of the following:
    Mac OS X with a Windows 7 or 8 Virtual Machine (use VMWare Fusion or Parallels Desktop for example. Note: VMWare Fusion seems to have some issues with Thunderbolt and USB3. Plug your drive to a USB2 enclosure or hub to work around this -it worked for me-, or use another VM software) → Read the important note below
    A PC running Windows 7 or 8 → Read the important note below
    Windows AIK (free) running on your Virtual Machine or on your PC, or just the imagex.exe file (the rest of the Windows AIK package is not needed)
    Download imagex.exe
    Download Windows AIK (this download and installation is not required if you have already downloaded imagex.exe)
    Bootcamp drivers for your Mac. You can get these either by running bootcamp from your Mac (Applications > Utilities > Bootcamp) or, if like me you have a 3TB drive and can't run bootcamp at all, use the direct download links here.
    A USB stick to store your bootcamp drivers
    IMPORTANT: If your Mac has a 64 bits processor, your Windows Virtual Machine on OSX, your Windows installation on your PC and your Windows DVD/ISO must also be in 64 bits!
    Step by Step guide
    Step 1: Get the install.wim file
    If you have a Windows ISO file:
    Mount the ISO
    If you're on OS X: double click on the ISO file
    If you're on on Windows 7: Use a software like Virtual Clone Drive (free)
    If you're on Windows 8: double click on the ISO file
    Open the mounted drive, then go to the "sources" folder and locate the "install.wim" file. Save this file to C:\wim\ on your Windows installation or virtual machine.
    If you have a Windows DVD: open the "sources" folder on the DVD and locate the "install.wim" file. Save this file to C:\wim\ on your Windows installation or virtual machine.
    IMPORTANT: If instead of a "install.wim" file, you have "install.esd", you can not continue this step by step guide. And an ESD file can not be converted into a WIM file. So you must get a version of the Windows installation DVD/ISO that has an install.wim file.
    Step 2: Clean, partition and format your external hard drive
    On your Windows installation or virtual machine, plug in your external hard drive (can be plugged using USB2, USB3 or Thunderbolt at this stage)
    Open the command prompt in administrator mode (cmd.exe). To run it in administrator mode, right click on cmd.exe > Run as admin.
    Type the following and hit enter to open the disk partitioner utility:
    diskpartType the following and hit enter to list your drives:
    list disk
    This will display a list of disks mounted on your computer or virtual machine. Make sure your drive is listed here before you continue.Identify the disk ID of your external hard drive. Replace # by your real external disk ID in the command below:
    select disk #Clean all partitions by typing the following (warning: this will erase all data from your external drive!):
    clean
    Create the boot parition by typing the following followed by the enter key:
    create partition primary size=350
    This will create a 350MB partition on your external driveFormat the partition in FAT32 by typing the following:
    format fs=fat32 quick
    Set this partition to active by typing:
    active
    Assign a letter to mount this partition. We will use letter B in our example. If B is already used on your PC, replace B by any other available letter:
    assign letter=b
    Windows will detect a new drive and probably display a pop-up. Ignore that.Create the Windows installation partition using all the remaining space available on the external drive by typing the following:
    create partition primary
    Format the new partition in NTFS:
    format fs=ntfs quick
    Assign a letter to mount this partition. We will use letter O in our example. If O is already used on your PC, replace O by any other available letter:
    assign letter=o
    Windows will detect a new drive and probably display a pop-up. Ignore that.Exit the disk partitioner utility by typing:
    exit
    Step 3: Deploy the Windows installation image
    Still using the command prompt in admin mode (you didn't close it, did you? ), locate the imagex.exe file mentioned in the "What you'll need" section and access its folder. In our example, we have put this file in C:\imagex\imagex.exe
    Type the following and hit enter (remember to replace o: with the letter you have chosen in the previous step):
    imagex.exe /apply C:\wim\install.wim 1 o:
    This will take some time. The Windows installation image is being deployed to your external driveOnce done, type the following to create the boot section (remember to replace o: and b: with the letters you've chosen in the previous step):
    o:\windows\system32\bcdboot o:\windows /f ALL /s b:
    If you get an error message saying that you can't run this program on your PC, then most probably you are running on a 32 bits installation of windows and you're trying to deploy a 64 bits install. This means you did not read the important notes in the beginning of this guide
    If you get an error message on the options that can be used with the BCDBOOT command, then it's because you're installing Windows 7, and the /f option is not supported. If that is the case, remove /f ALL from the command and retry.
    Step 4: Boot from your external drive and install Windows
    Plug in your external drive:
    If you've done all the previous steps from a Windows PC, unplug your external drive from your PC and plug it to your Mac, either on a USB3 or a Thunderbolt port.
    If you've done all the previous steps from your Mac using a Virtual Machine, ensure the external drive is plugged in to a USB3 or Thunderbolt port. Using USB2 should also work but you'll get very poor performance so I don't recommend doing that.
    Reboot your Mac and once the bootup sound is over, immediately press the ALT (option) key and release it only when the boot drives selection screen appears. If you did not get the boot drives selection screen, reboot and try again. The timing to press the ALT (option) key is quite short. It must not be too early or too late.
    On the boot selection screen, choose "Windows" using the arrow keys on your keyboard, then press enter.
    The Windows installation starts. Follow the on-screen instructions as normal. The installation program will restart your computer one or 2 times. Don't forget to press ALT (option) right after the bootup sound, and boot on Windows again each time to continue the installation.
    Step 5: Install bootcamp drivers
    Once the Windows installation is complete, plug in the USB stick where you stored the bootcamp drivers (see "what you'll need" section), open it and right click on "setup.exe" and select "Run as admin". Follow the on-screen instructions.If you have an error saying that you can't run this program on this PC, obviously you have installed a 32 bits version of Windows and the bootcamp drivers for your Mac are made for a 64 bits version. You have to restart the whole guide and make sure to get a 64 bits version of Windows this time!
    Once the bootcamp drivers are all installed, reboot and press ALT (option) after the bootup sound to boot on Windows again. And Voilà, you have Windows installed on your USB3/Thunderbolt drive running on your Mac.
    Now each time you want to boot on Windows, press and hold the ALT (option) key after the startup sound and select "Windows", then press Enter.

    Hi i'm trying to follow your guide, I installed windows 8 on bootcamp to do it planning to remove it after the operation is done, but i get stuck at part 3: every command i give to imagex i get a pop-up ftom windws asking how do I want to open this kind of file install.wim and imagex does nothing, what do i have to do to stop those pop-ups?

  • Weird problem with A300 and external drive

    Info about my comp: A300-29U model Windows 7 ATI Edition (32) SATA Unknown External Drive ----- Ok, so yesterday I plugged in my external drive as usual to check some music. Everything was ok and I went to sleep. This morning when I woke up and tried that again the computer doesn't see external drive. You hear that sound when you turn it on/off, but it doesn't show or even do auto-run of my external drive. I changed 3 new USB cables and plugged in into 3 differen USB Hubs and everything is the same... I checked in Device Manager, it says that device is working fine, but I have 2 Base Missing Driver errors. I suppose that's for this external drive, but I don't have a clue how to fix it. I downloaded new chipset/bios drivers and have a fresh Avira installed. Any tips?

    If you have a two devices banged out, deleted them and restart.  It should auto detect the devices and load the driver.    I had a problem like this.  That worked for me. 
    What kind of hard drive is it.
