USB port gone after ejecting external HDD

All software uptodate.
I have strange issue with USB ports. After ejecting USB drive (external HDD, powered by USB bus), which worked perfectly, USB port does not recognize anything, nor providing power. Turning MBP off and then booting back solves this issue.
Any ideas?

After some time I connected external HDD to "dead" port again. And got power. But still no devices recognized on this port. For example: iPad does not charge, not recognized.

After a clean HDD install of Mountaion Lion, the OS automatically ejects external HDDs.

Why? Oh WHY???

IMac keep ejecting my 2TB external HDD but in safe boot mode it is totally fine. How to resolve the problem?

Hi,
I have WD 2 TB external HDD. It has two partitions, one I use for my time machiine backup and one for my personal files and documents. Recently the iMac keeps ejecting the external HDD as soon as it gets connected to the iMac. I tried to reboot the computer in safe boot mode (by holding down the shift key at startup) and found out that problem is not there anymore. I can access my external HDD there and it never ejects the HDD.
It seems like the HDD is fine, the problem is with the iMac. Can anybody please give any solution to this problem?
Thanks!

Thanks Allan for your reply!
It makes sence that there must be some log in /start up item which is causing this problem. I went System Preference>Users & Groups> Login items> disabled all the items there to make sure, and restarted the computer but the problem is still there
Is there any other way to stop/configure the log in items?
Thanks again!

How to avoid TM to back up entire external HDD to TC again after eject/reconnect to MacBook Air?

I back up my MacBook Air internal HDD and an additional external HDD plugged into the USB port of the MacBook Air to my Time Capsule using Time Machine. However, if I remove/eject the external HDD and then reconnect it TM tries to backup the entire contents of the external HDD again.
Is this known/expected behaviour, or is there some config trick to avoid this?

It shouldn't, unless that system does something really bizarre, like assigning a new UUID to the drive.
That was my thought as well. When an external drive has not been connected during recent backups (potentially 25 or more if a whole day went by), TM may not have as much cached data about changed files, so while it may appear that TM is backing up the entire drive anew, when all data is updated only new data is retained.
Kanitsky, what messages or status are you seeing that sugges the entire external HD is being backed up when reconnected?

External HDD: Shows not ejected properly when the drive is still present

Hi,
I have a Seagate 500 GB external HD, the big one with power adapter. I connect to my MBP with a USB cable. Recently, every now and then, I am seeing the message "Your external disk was not ejected properly. Always make sure you eject blah blah..." even when the disk is firmly planted onto the Mac. I can see the disk in my desktop and finder. But keep getting this message nevertheless.
Another observation is - If I have Picasa open, Picasa fails to load the pictures in the external HDD when this happens. Pictures that has been earlier added to Picasa library, that is, which should ideally show up when the HDD is connected.
Any ideas?

Try a different USB cable. If that doesn't work, go to Seagate's web site and open a tech support request with them. If a new USB cable doesn't help, there is probably a problem with that disk drive such as outdated firmware.

Is there a solution to external HDD ejecting during backups?

I've used Super Duper. I've used Time Machine. I've tried copying tons of files from one external HDD to another. Every time, the backup crashes and delivers the message that said HDD was not properly ejected. This did not happen with Tiger, but started happening with the upgrade to SL. From everything I've read, it points to a bug in Snow Leopard. If so, has it been fixed?

FWIW, when I said earlier in this thread that I back up every day I'll add here that one of the drives I backup is my boot SSD with no problems.
Here's something I just thought of -- by any chance do these externals have firmware that needs updating for snow leopard (and lion)? For example, you said it worked on tiger (10.4.x) but you started having problems when you tried snow leopard. Since you mentioned the model of the WD external I did a little searching and found a WD Software Update page for firmware for WD products. Perhaps you need that. I didn't check the LaCie since you didn't specify the exact product and LaCie makes lots of stuff.
Just something I thought I'd mention.

Is my External HDD about to fail? Help!

I bought a WD my book for mac 1TB, towards end of Jan. I have a 2008 13" unibody Macbook running Snow leopard 10.6.2. the external HDD had been working perfectly fine with time machine, backing up regularly as it should without any issues. However today I ran into my first problem, where it simply got stuck on 'indexing backup' for several hours. After losing patience I used disk utility which confirmed there was a problem, and told me the disk could not be repaired and needs to be formatted. Luckily I was still able to access the disk and was able to copy over a few important files. I just formatted the disk using disk utility and i am running a fresh backup as I write this. My question is whether this is a warning sign of impending hard drive failure, or is this a perfectly normal occurrence that happens every so often? I'd rather act now than wait and lose anything important because of a dodgy hard drive.

Its got USB input, I would never pull out hte cable without ejecting in a proper way. However there were times whenr the error message saying, 'the disk has been unplugged without being ejected properly', would pop up, despite the USB still being connected to my macbook. It would then reconnect itself and go back to normal. It was doing that regularly, though it has happened for a week or two now. Is there a serious problem underlying all this?

WD My Passport External HDD in a Mac

Hey everyone. I want to know if it's possible for me to replace my 160GB HDD in my MacBook (Aluminium, Late 2008) with my WD My Passport 1TB External HDD? And if the answer is yes, how do I download and install Mountain Lion to it after the replacement? (I did a download and upgrade from Snow Leopard to Mountain Lion through the App Store) Thanks.

Here's the basic process:
How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your new hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

My External HDD is not recognized on OSX 10.7.5

Hi There,
I have a Western Digital My Passport external HDD 1TB.
I have been using it on both Mac OS X and Windows, as that's how I formatted it originally.
Today, my Macbook running 10.7.5 is not recognising the external drive.
When I plug the drive in I can see the power light coming on, so there is power going to it.
It is also working ok on a Windows machine.
I have tried it on different USB ports on my Macbook but it is not working.
I have searched online for updates, and tried to reboot a number of times.
When I last used the HDD on my Macbook I accidentally unplugged it without ejecting it.
When I ejected it Quicktime Player was open & playing a file from the HDD.
I assume this I was has caused the issue.
Anyone got any advice on how I can fix this problem?
Thanks in advance.

i can see it in disk utility but i am not able to mount it.

External HDD & Disk Utility/Terminal

I wanted to be able to read/write to my Woxter external HDD which is an NFTS partition. so I tried using MacFuse. I followed these steps:
# Install the packages, MacFUSE Core first, then install NTFS3g.
# Plug in your external HD (if you have one)
# Open Disk Utility
# Click the partition you want to mount with read/write capabilities and unmount it if it is mounted by clicking the button up top.
# Click info up top and look for Disk Identifier. Mine was "disk1s1"
# Open the Terminal
# Enter the following (copy and paste) “sudo ln -s /System/Library/Filesystems/fusefs.fs/mount_fusefs /usr/bin/mount_fusefs”
The ln utility creates a new directory entry (linked file) which has the same modes as the original file. (man)
# Enter “mkdir /Volumes/ExternalWoxter” This creates the directory where you can find your files.
# Enter “sudo /usr/local/bin/ntfs-3g /dev/disk1s1 /Volumes/”ExternalWoxter” -o ping_diskarb,volnameforce=”ExternalWoxter””
I´m trying to back up files from my Mac to my Woxter, disk utility tells me that I have read/write access, but I get a message saying I have insufficient privileges to be able to complete the operation - so I can´t back up the files.
Also - my woxter external HD no longer auto-mounts when I start up the mac.
And its icon has changed from the old one to a new icon, the same as the one for Network (you can see an example of this icon in the preferences menu).
Also - when I click on Macintosh HD - I have one icon for the woxter drive for EVERY TIME I have mounted the drive... it doesn´t disappear when I "eject" the drive.
Can anyone tell me how to fix this? please?

If you have more than one user account, you must be logged in as an administrator to carry out these instructions.
Triple-click anywhere in the line below to select it:
sudo rm -i /V*/*/.DS_Store
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning not to screw up. Confirm. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
You may be prompted to remove one or more files named exactly ".DS_Store" (without the quotes.) Press the Y key and then return to confirm. Press the N key and then return if you get any other response, or just close the Terminal window.
Try again to open the volume window.

Disk Utility Failing to Repair External HDD

I was in the midst of running a Time Machine backup from my MBA (2012, running Mavericks) to an external HDD when I moved the laptop and managed to knock the cord out of the HDD, causing it to disconnect abruptly (the drive pulled away from the plug and hit the floor). Since then, I have been unable to to access the HDD at all, although the drive itself seems to be working, insofar as the light still comes on and the disc is spinning.
The HDD isn't visible in Finder. I can sporadically see it in Disk Utility - sometimes I plug it in and see nothing, sometimes it appears in Disk Utility after an extended period of time. It won't mount through Disk Utility, however I have managed to eject it a few times.
I have tried both verifying and repairing the HDD when it is visible; all attempts have ended in an error stating that I needed to backup the files and restore the drive. I've tried a number of tools to clone the drive, including Disk Utility itself, Carbon Cloner and a few others, but all have resulted in errors.
Is there any way I can salvage the data on the HDD? There are a few files on there I really don't want to lose...

Remove the drive mechanism from the enclosure and install it in another one.

Favoring FireWire interface over USB for external HDD

I have my iMac hooked up to an external HDD via both USB and FireWire 800 as it is triple-interfaced (USB, FW 400 & FW 800).
Lately, as I turn on the external HDD (pretty much always once the iMac is up & running), the HDD icon shows in the Finder with the USB symbol.
It requires me to eject the HDD in the Finder and then disconnect the USB cable for the iMac to detect the external HDD again but now through FireWire.
The reason I use both interfaces is to handle HDD read/write communication via FW whereas USB only as hub (the external HDD comes with 3 USB ports).
Is there anything I can do to make sure the primary interface is FireWire and not otherwise?
Thanks!

In a recent phone call with OWC's tech support I asked the same question. Answer was "Do not connect both interfaces at the same time". There is no way to arbitrate the connection the Mac will use, and strange things will happen.
If you think about it, there is no way to specify a preference in the Mac for what ports to connect with, so it does what it wants, not what you'd like.
I can only imaging what happens on Windows machines. I suspect corruption ahead

Quicktime/Snow Leopard/External HDD Sleeping

Hello,
I recently bought a Mac Mini - very happy with it so far, however i have now got one small problem...
I previously had a PC with WinXP on it, and i stored loads of college and work related odds and sods on my WD 500Gb External HDD. So i connected it to my brand new mac, and it works beautifully....except for when i go to play a video in the Macs built-in Quicktime. The video is being loaded from my External HDD will get about 5-10 mins in then the HDD will go to sleep...like it's not being used....This then crashes Quicktime and Finder comes up with an error message "You should not eject a disk while it is being used...ect"
Cheeky Mac! I didn't eject it, it feel asleep and thus disconnected itself to save power or somethink....
I was wondering if anyone else has had this problem, or if there is something really obvious i'm doing wrong.... Can anyone help?

You may want to check with WD and tell them you are using it with a mac. I think it's firmware may not know it's on a mac and puts it to sleep. I know seagate for windows drives on a mac can do this.

Aperture - library management and external HDD question

Hi all.
I have just graduated from a point and shoot to a Panasonic GH2 (love it), and have now begun using Aperture 3 rather than iPhoto on my early 2008 MB Pro to manage my photos going forwards. Of course, I’ve now discovered that Aperture is quite the resource hog and so it’s upgrade time (darn, “have” to buy a new ‘puter!). I have a 2011 MB Pro (2.3Ghz i7 with 512GB SSD) on order and 8GB of DDR 3 arriving from Crucial. Since I have this brand-new-computer opportunity I want to make sure I’m organising things properly before I start transferring things across, and so have a few Aperture-related questions. (In case it’s relevant, I’m shooting in RAW+JPEG. So far I’ve been using RAW as master, but have since learnt it might be a good idea to import JPG as master and switch to RAW only when I need to make corrections, so I’ll probably do that going forwards.)
I understand that moving to referenced masters on an external drive might be a good idea and save me precious SSD-space. To that end, questions are:
1. Can anyone recommend a companion external HDD for Aperture and the 2011 MBPro? I guess either FW800 or Thunderbolt are the way to go. The Lacie Little Big Disk Thunderbolt might be an option but is this overkill for Aperture masters or would FW800 be sufficient. I’ve also seen the G-Tech G-RAID mini, Lacie Rugged – thoughts welcome.
Key requirements are a) as compact as possible, and b) bus powered.
2. What kind of performance can I expect if I go down this route? Is there going to be significant loading/processing delay whenever I switch to a new image?
3. How will Aperture cope with (eg) syncing photos to iPad / iPhone if the drive containing the masters isn’t connected? Put another way, are JPG renders saved in the Aperture library (i.e. on my MBP SSD) or with the masters?
Thanks in advance to anyone who responds!

OWC (an excellent vendor) has the Elite Pro Mini hard drive that meets your specs:
http://eshop.macsales.com/shop/firewire/EliteALmini/eSATA_FW800_FW400_USB
Thiunderbolt drives are not mainstream yet but eSATA and FW800 both work well. The multiple connection methods of OWC drives allow very desirable flexibility when purposing/repurposing drives.
Note too that the MBP optical drive can be replaced with up to a 1-TB hard drive DIY or OWC will do it for you. That is what I am doing with my 17" 2011 MBP.
2. Is there going to be significant loading/processing delay whenever I switch to a new image?
SSD latency is orders of magnitude less than hard drives. Switching to a new image even fast hard drives with fast connectivity add significant latency delay. To avoid that what I do is leave (Referenced) Masters on the SSD until all editing is complete (which may be a few weeks). Only then do I use Aperture to change the Referenced Masters location from the SSD to a large external drive.
What kind of performance can I expect if I go down this route?
With Masters on the SSD and 8 GB RAM imports/exports are very fast and all Aperture editing is essentially instant. You will be pleased!
Suggested workflow steps for Referenced Masters:
• Use a FW card reader or MBP slot to copy to a file folder on the SSD (never directly into Aperture or any other images management app). With fast camera cards copy times are quick, but cheap slow cards can slow this step down a lot.
• Eject and physically disconnect the card reader.
• Back up that file folder on external drive(s).
• Only after backup is complete, reformat the camera card in-camera.
• Import images into Aperture from the file folder on the SSD.
