External Hard Drive Fail After Waking from Sleep

Hi,
I've been having this issue for over a year (since upgrading to Lion, and now still persists after upgrading to Mountain Lion), and I haven't been able to find the exact answer I need after searching through the posts here, and on the internet.
I have a 2011 MBP, and after upgrading to Lion last year, I've noticed that my WD external hard drive for the Mac has issues to be recognized after the laptop wakes from sleep. The drive icons are still there on the desktop, and all the files are listed. However, I cannot open any of the files, and Time Machine backup automatically fails.I am able to eject the drives by dragging the icons into the trash can. However, nothing happens if I simply unplug the fire wire 800 cable and re-plug it into the computer after ejecting the drives. I need to reset the external drive by unplugging both the fire wire cable and the power supply, and replug everything.
Aside from being a hampering process after waking from sleep, this is also very stressful on the drive itself, so I would like to fix this. Does anyone know the issue behind this or have a solution? Thanks in advance!

Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK.  I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

  • External Hard disk unresponsive after waking from sleep

    i have an external usb2 drive connected to my 15" mbp. when waking from sleep, the drive is shown as mounted by accessing it gives me the spinning beachball icon and the computer stops responding until i pull out the usb cable from the mbp. it then proceeds to give me a device removal error. the external drive draws power from the usb bus.
    other than this one issue the hard drive works perfectly on both ports.

    I got home from work today and was forced to hard restart AGAIN. It seems to be happening more and more often now, but maybe that is just me.
    My logitech revolution mouse has never caused problems before with a g4 powerbook or g5 tower. The last thing I added was the apple wireless keyboard. I can't imagine it being the problem since it is using an apple product with an apple computer.

  • Disk drive thrashing after waking from sleep

    Apple conundrum - iMac goes from sleepy to grumpy....
    At times after waking from sleep mode, my disk drive thrashes for up to 3-5 minutes. The thrashing almost always includes an SSBOD. Then it stops and things seem fine.  My iMac is not backing up as I check for the TIme Machine icon activity.  I have also checked and disk permissions and keychain ae fine.
    Any ideas on what is causing the disk thrashing.... and how to fix it.
    Thanks
    Bruce

    To find out what the Mac is getting grumpy about, open your Activity and check to see what it's doing those first few minutes.

  • Mac Mini WiFi (airport) fails after waking from sleep

    I recently bought a Mac Mini (Mid 2010 model)...my first Apple computer since my dearly departed IIe.  I've been having repeated intermittent issues with the WiFi on this machine.
    Owning it for two weeks, then one day it woke from sleep, and decided it no longer knew the password to my wireless network.  With everything else in my house on wireless, I knew that the password had not been changed (I am using WPA2).  Every time I would retype the password, I would get either a 'Connection Timeout' error, or an 'Incorrect Password' error.  Every once in a while it would connect, but it would not get a valid IP.
    Restarted the system, and then it tells me there's 'No Airport Card Installed'
    Reset PMU/SMU/PRAM (etc) and the airport card comes back, but it STILL will not connect.
    I go into keychain, and delete the saved wireless password.
    I create a new 'location'.
    No go.
    So I made a trip with my machine to the Genius bar at my local apple store.  Miracle of miracles, it WORKS PERFECTLY from the moment they turn it on. Get it home, it continues to work perfectly.  This was Saturday.
    This morning, same problem starts again.  I was having similar issues with my iPad not connecting to the WiFi when waking from sleep, but this was fixed when I factory reset the iPad.  I've never experienced this issue with either of my iPod touches (3rd and 4th gen).  I'm not having any wireless problems with my PS3, Wii, Blu-ray player, Android phone, Nook, HP Printer, or Windows laptop. 
    My router is a D-link F5D8235-4 v2000, with firmware 2.01.09 (latest available)

  • DNS Lokup fails after waking from sleep

    Since the recent update, whenever my computer wakes from sleep the DNS Lookup fails and I cannot connect to the internet for 30sec-1minute. I've never experienced this problem before. Any thoughts?

    FWIW, I never sleep my machines or their HDs, just their displays and never have an issue waking up the displays, usually run 24/7. Give that a shot.

  • IMovie -Problem restoring events after external hard drive failed.

    iMovie 09 – The external hard drive failed where I stored my 2012 events.  I do not have a backup copy of these events. I bought a new external drive and named it exactly the same as the old drive. Then I uploaded archived original video clips to it recreating the events.  I used the exact same event names.  However when I view the projects I made from the original events, I get “this clip’s media file is not currently available”. The file path I created should be the same as the old, so why does the project not recognize the recreated events?  Any suggestions what I could try?
    If I were able to retrieve and copy the old events from the failed drive to the new drive, would that work?
    Has anyone successfully dealt with this problem?

    That's a very interesting scenario that you've described. I've been concerned about a potential situation arising where I may need to restore Events from a backup drive. However, your situation is somewhat different in that you've had to re-import the Events to a new drive from an archive.
    My main video drive is a Maxtor One Touch III Turbo comprising two 500GB drives set up as a RAID 0. So, effectively it appears as one drive totalling 1TB, with data being written to both drives simultaneously (but not mirrored). However, if one drive fails, the other becomes ineffective as it contains only partial data about imported clips (the remaining data being on the failed drive).
    I backup the Maxtor to a portable 1TB drive by cloning it using SuperDuper. My thinking has been that, if the Maxtor fails then a simple rename of the backup drive to the same name as the Maxtor is all that will be required for iMovie to retain the linkages between Events and Projects. I hope this is the case!
    I hope you get a solution to your predicament - sorry I can't offer any useful advice!

  • System clock fails to update after waking from sleep

    I've noticed that my new PowerMac G5 Dual-Core 2GHz (running Mac OS X 10.4.3) doesn't update its system clock to the current time after waking from sleep.
    When I put it to sleep and then wake it some time later, the Clock in the upper right-hand corner doesn't update to the current time. It still ticks on (second for second) but remains out of sync.
    Opening the Date & Time preferences pane will restore the time to the correct setting.
    This problem only occurs with sleep and then wake-from-sleep. It doesn't happen when I shut down the machine and then restart it.
    Does anybody know if I've got a malfunctioning machine? It's only 1 day old...
    Or better still, how do I solve this problem?
    PowerMac G5 Dual-Core 2GHz   Mac OS X (10.4.3)  

    No, my Mac is not having trouble contacting the time server. I checked the console log and found no messages related to this.
    I am on a broadband always-on connection (recently switched from DSL to cable modem, and the problem occurred under both connections). However, my original post states that the computer loses time only when it is asleep, and I didn't think that my computer could contact the time server when it is asleep. It also loses time when it is off, which I neglected to mention previously. Am I mistaken in thinking that the computer communicates over the network only when it is awake? Since it keeps accurate time when awake (once I've reset it by opening the Date & Time control panel), it seems to me like it IS communicating with the time server without issue.
    [And I apologize for misinterpreting your question as a suggestion. I was trying to be polite by thanking you for taking an interest in my issue. I'll watch my semantics more carefully next time.]
    Cheers,

  • My WD 2tb external hard drive will not unmount from my MacBook Pro.

    My WD 2tb external hard drive will not unmount from my MacBook Pro. It no longer even shows up in finder, however it does show up in Disk Utility. I have tired so many of the suggestions on the internet all to a fail.
    I keep getting the message to be sure that all applications are closed before ejecting the drive. I have no clue how to tell which appliactions are using the external drive to shut them off. I turned off Time Machiene to be safe. 
    I don't need anything on the external drive, I am just trying to erase it, save my current info, and migrate it to my new MacBook Pro.
    I have been about four days now with this issue all over the internet, in this community, and watching videos on everything and nothing about this topic to a fail.
    I think I am doomed and have lossed this external drive because of some wierd application that will NEVER close on my hard drive for it to disconnect correctly. It's annoying.
    Does anyone have a solution?

    Have you trie using another USB port? Can you test the USB ports with other USB devices to assure they are working? You may want to reinstall OS X in case there has been a driver glitch.
    Reinstall OS X without erasing the drive
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard 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 Utilities menu. 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.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • Restarting after waking from sleep

    I have a mid 2010 macbook pro running Mountain Lion OS X 10.8.3 of which keeps restarting after being left in sleep mode for an hour or two. When waking from sleep mode, the mac functions for about 5 seconds, before restarting by itself. I have tried deleting certain plist files (as suggested by other posts) but that doesn't seem to have helped. I have also recently installed a new hard drive, but i continue to have the same problem. Below is the panic report from the recent restart after waking from sleep mode:

    Replace the pair of DIMMs first.
    Monitor the temps inside.
    Install and use SmcFanControl 2.2
    Run Apple Hardware Test
    You may want to try a clean system install to test with once you have the RAM replaced. Faulty RAM can cause all kinds of issues. And dirty files. Some deeper check for corrupt files than Disk Utility is probably in order.
    There is a significant "Inrush-current" on boot and wake from sleep with the 2008s. They need good power, a 1500VA/900W UPS, and sensitive to other equipment on the same circuit.

  • Macbook Pro restart after waking from sleep

    Hi all,
    Since I've installed Mountain Lion (10.8.2) on my 13" Late 2011 Macbook Pro I've been experiencing a quite annoying problem. The computer, which is connected to an external monitor through Thunderbolt to HDMI will restart (Sometimes to a gray screen with a progress bar) after waking from sleep. I've done some research and it would appear as though the problem is related to the display driver.
    I'm wondering if anyone has any experience with this peculiar problem or if there's a quick solution.
    Thanks!

    Maybe this will help. If you monitor the "More Like This" box, other solved threads appear. Opening them usually displays other threads.

  • Keyboard volume keys don't work after waking from sleep

    This problem has existed for many months on my 2009 Mac Pro. I'm running 10.6.3. The problem is reproducible 100% of the time. I use external speakers. Sound output is set to "Line Out."
    1. Boot machine. External speakers work fine. Volume keys on keyboard (F11, F12) work correctly.
    2. Put machine to sleep.
    3. After waking from sleep, F11 and F12 no longer control the volume of the external speakers. The "pop" noise when hitting F11 and F12 is emitted from the internal speaker. The mute key (F10) does work for the external speakers, however.
    4. The keyboard volume controls become responsive again by switching the sound output from Line Out to another output option and then back to Line Out.
    This bug is a huge hassle. Does anyone have a solution?

    I have several mid-2009 8-core Mac Pro's, all running Snow Leopard, and all have been having this problem as well.
    I will not guarantee this is going to work for anyone else....but we have found a (slightly inelegant) workaround for it that has been working for several weeks now without fail.
    Prior to putting your MacPro to sleep, run the volume all the way up and leave it there. Afterwards, put it to sleep as usual. We use the keyboard to do this, but I would imagine any method should have the same affect. However, I've not experimented.
    Anyway...this has worked 100% of the time for us. The only downside of it is that you have to remember to run it up before....and then back down after waking (else that first alert sound or music file you play will really wake YOU up!)
    If this works for anyone else, let me know.
    Apple should never have let this one out the door with this bug. Especially, as Apple Support is....wanting, at best.
