External Hard Drive No Longer Working After Being Removed From Mac

The following issue is happening to two other mac users that i know and its quite frustrating.
So if an external hard drive is not ejected properly from a mac, it then cannot be recognised by any other Mac’s. This issue is not isolated to just one external hard drive.
Then if i plug the external hard drive/s into my 8 year old Dell (PC) it works fine.
Further to this when i check the hidden files on the PC it looks as though Old Apple imbeds the external HD with a bunch of useless hidden files, once these are all deleted it miraculously works  again on the Mac’s.
Too bad if you only have a Mac Because if the Mac disk utility can read the External HD it says that the disk has crashed and needs to be replaced.
Nice one Apple...
So now for my questions.
Why does mac add hidden files to an external hard drive when not ejected properly that prevents it from operating again on a Mac ?!!!!
How do i prevent apple from adding these hidden files?

Can you see the drive in Disk Utility? If so, try selecting it and using the Mount button in the top menu. You can also run repair disk and repair permissions.

  • External hard drive no longer found after becoming full from time machine, External hard drive no longer found after becoming full from time machine

    Hi, I have been using an external hard drive as a backup for my Mac using Time Machine.  I was under the impression that once the backup drive became full, it would start to delete previous versions of the backup.  However, instead of doing that, it has just stopped working and I now cannot access the hard drive via a Mac or a PC.  On the PC, it does at least show up in that it will allow me to disconnect it safely but I cannot do anything else with it.
    I am now looking to reformat it, and start again from scratch - but can't do this as it doesn't show up anywhere.  Does anyone have any advice about how I can get this working again?
    Thanks.

  • LaCie external hard drive no longer readable after being connected to a PC

    Hi all,
    First post here and I really worried.
    I have a Lacie external drive which I normally connect to my Mac - no problems.
    Tried to connect it to my Windows 7 pc to transfer some files and it wasn't recognised. It installs the drivers and says its ready to use, but doesn't appear as a drive. So I read about it and the advice was to go to Computer Management - Disk Managment and mark drive 1 / partition as active and then assign a drive letter. So I did that and then Windows tells me that I must format the drive to use it.
    Obviously I don't want to as I can't loose my data - my wedding pictures are on the drive!
    So I've plugged the Lacie back into my mac, and the drive is unusable and says I need to format too. Even the repair function doesn't work.
    Now I've read the another post and downloaded Test Disk (I'm working off my mac though as I know the drive worked and all my files where added from the Mac).
    Its currently Anaylsing the cylinder but its taking a long time. 24hours and still on 30% (1TB drive, firewire)
    I've read the help guide but once this stage completes, having read the next few steps, I'm lost.
    Any ideas on what might have happened and what I need to do next?
    I'll report back once its finished its 'deeper search' and analysing.
    Or do I abort the above process and do something else?
    Please help.
    Thanks in advance,
    Nick

    I've read the help guide but once this stage completes, having read the next few steps, I'm lost.
    And those few steps were?  Care to share?

  • External hard drives no longer working in Mavericks - HELP!  I need my data...

    Hello
    I recently upgraded to Mavericks (10.9.2) and this morning I was trying to find some files so connected my external hard drive (back-up 1).  Light went on...nobody home.  The drive didn't register as it had done last week.  In my hurried state I plugged in external hard drive 2 (back-up 2) and the same thing happened.
    Not phased by this I took my hard drives to work and tried them in my PC and also a friend's mac (not upgraded).
    Annoyingly I cannot access anything, in fact they don't even register existence even though they are whirring with the lights on.
    Please help! I need my data

  • External Hard Drive no longer working

    Hi Everyone,
    I am hoping for a positive response.  I have a SimpleTech (SimpleDrive) Model 96300-40001-001 external hard drive that I have been using for about 2 years now.  The drive has extermly important information on it. 
    I just returned from vacation and attempted to reconnect my drive, using it's standard USB Cable, and received the error message of, "The disk was not ejected properly."  After reading several previous topics, I attempted to do the following, with negative results:
    Reset SMC and PRAM
    Change USB Cable
    Change Power Supply
    Attempted to do Disk Repair, although, unable because the computer would eject the drive
    When I first did a PRAM reset, I was able to double click on the hard drive from my desktop and see it's contents on the drive, but, when I tried accessing any of the files, I received the error message once more, (The disk was not ejected properly).
    I am currently running a MacBook Pro, Mac OS X, 10.6.8, 2.53GHz Intel Core 2 Duo, with 4GB of Memory.
    Any advice or suggesstions would be exteremly helpful, as I am trying to access the information left on this drive, which are very important.

    Hi, Glenn900. Welcome to the Discussions.
    Assuming the hard drive mechanism itself isn't damaged (and that's a big assumption given what you described) the partition map of the drive may be damaged if it was connected to your computer and running when it went for its flight.
    The partition map on a running, mounted external hard drive can become corrupted if the external drive is disconnected or powered-off without first being Ejected.
    I frankly think there's a good chance that the drive may be damaged if it is not a portable external drive, i.e. one specifically designed and somewhat hardened for carrying around. The enclosure for a conventional, desktop-oriented external hard drive is not hardened, meaning they generally don't respond well to becoming projectiles.
    However, if there's a chance to recover any of the data from the drive, my "Data Recovery" FAQ may help you with this problem.
    Good luck!

  • External Hard Drive doesn't work after Time Machine cancelation

    First post on the forum.
    So far i've had 2 hard drives broken because of a simple Time Machine.
    I own a MBP and an HP so my hard drives usually have 2 partitions, one for mac, the other for pc. About a month or so i was doing a Time Machine on my Iomega 1TB (the partition used for the time machine is formatted in Mac Os Expanded (with journaling)),  and, because the time machine was extremely slow i stopped it. Then came the problems. I tried to connect the Iomega to the mac, but the partition in which i had the time machine doesn't mount. the other partition is mountable and i even managed to delete some files in it, so it worked. But now the partitions don't mount. I can still see the two partitions in Disk Utility, with the correct names i gave them, but cannot mount.
    Right now i don't have the disk with me because i went to a "professional" to try and at least recover my files. What a joke that was. First they told me they had my recovered files and them the files were not mine. The switched the disks and gave me someone elses files. And now they ask me for 1100$ to recover my files because it is a hardware malfunction. Obviously i dont have that amount of money available and i cannot afford the recovery atm, and i do not believe that a software can cause hardware to fail. (just guessing)
    Resume: 1 external hard drive, with 2 partitions, one mac os expanded and the other is a Windows NT Filesystem. None of the partitions are corrently mounting on mac but the disk utility recognizes the partitions and the names i gave them.
    So guys can u help a poor little girl that needs her photographies so that she can go and show her portfolio to get a job. :/
    Kinda desperate at this point.
    ps: sorry for bad english, second language

    One can't read the other.
    Just to be clear Mac's can read/write FAT32 but windows cannot use OS X Extended. So to use a drive on both systems it needs to be formatted FAT32
    FAT32 does have limitations and possibly the best solution is to use NTFS, a more modern, robust filesystem. The drawback here is that OS X does not natively read NTFS so a third party kernel extension is needed.

  • Why does my external hard drive no longer work

    I have a toshiba 1tb external hard drive on which I back up my Toshiba lap top. This morning when I tried to do this both USB ports on the laptop died. Thats a very short explanation for what has taken some time to establish. To get them working again I have to reboot the laptop & then I can use my wireless mouse & keyboard etc. Attach the harddrive again everything dies.
    Now the point that got me to this board is that I gave my hard drive to a colleague to copy some files (which he did) but he runs a mac! Has his mac killed my hard drive & done something that somehow means when it plugs into my laptop it kills the USB drives on that too?

    Bob you might just be right. He might have killed the cable though. I've managed to find a similar connection & I now seem to have access. Is that a natural breeding rainbow or one of those bloated stockies?

  • Seagate external hard drives don't work after installing Mavericks 10.9

    I have a 3 year old MacBook Pro.  I upgraded the system to OSX Mavericks 10.9.  Since then my computer does not recognize any external hard drives.  I have a 1 TB Seagate external drive and a Seagate Free Agent 750 GB hard drive and my mac does not recognize either of them.  Prior to the upgrade my Mac could read and write to the drives. Below is the message I receive when I plug in the 1TB hard drive.
    The NTFS volume that you're trying to mount (/dev/rdisk3s1) has not been unmounted properly.
    This may mean that the volume is in an inconsistent state, and mounting it with NTFS-3G could lead to data loss. You are recommended to attach the drive to a Windows computer and unmount it properly with the "Safe remove hardware" feature to guarantee the safety of your NTFS volume.
    Please help.

    Have you tried the recommended steps?  If the Windoze machine won't allow you to safely eject, restart the computer and try ejecting again.

  • My Seagate Expansion 500GB external hard drive no longer works with my Mac

    Hi
    i have had a seagate expansion hard drive for the last year ish and it has worked as a time machine without any problem. when i first got it i had to format it to windows but that was simple and worked well. recently i unplugged it for a few weeks and have recently plugged it back in. now it won't register as my timemachine or show in finder.
    I went into disk utilities and clicked 'repair' then click 'verify and these are the two errors i recieved.
    Verify and Repair volume “Jon & Sarah Time Machine”
    Checking Journaled HFS Plus volume.
    Checking Extents Overflow file.

    I am hoping that someone has had the same issue and is able to help me with this problem.
    all my back ups are on the hard drive so i really don't want to have to format it as i don't know what i will lose.
    I have checked for updates for my Mac and it says there are none.
    cheers
    Jon

    You need something stronger, such as DiskWarrior, to repair the HD.

  • Flash drive no longer works after being connected to a Windows XP machine.

    After being opened on a Windows XP machine, the contents of my flash drive now shows up on my Macbook pro as a single .lnk file. What happened? It's MS-DOS (FAT32).
    Is there any way out of this or has all my data been lost? I've never experienced this issue previously.

    Thanks. I've now scanned it with both Sophos and ClamXav and both have come up negative for infection.
    At least while the scan was running I could see that all my data is still there as the name of each file appeared as it was going through the scan.
    My efforts to sort this out seem to have made things worse as now it opens up word whenever I try to see the contents. I'll try it on a PC tomorrow and see if I can figure out what happened. Looks like the file system has been damaged in some way.

  • External hard rive showing no information after being plugged into mac

    plugged a external hardrive into my mac it had information from another format on it windows now its showing theres nothing on there when converting format to run with windows, i have ran a iskysoft data recovery program it seems like its found a lot of the files lost, when its says do you wish to recover them i obviously have to pay them for the full program. before i do this can any one help me out as dint want to waste the money if its not going to work. the files are not mac format so not sure if it will get them back????

    osx is unable to read data from a different format. so your only option is to get to your data using windows or yes, pay heavily for third party software to retrieve.

  • External Hard Drive no longer working. Repair disk not working

    It appears in the finder, but says I should take everything off of it and restore it.
    Weird thing is, it says it's a 465GB capacity, and 236 is available, with 56,708 files on there, but it says 0 items in the finder, so it can't see everything.
    I have important stuff backed up on there, but it's not loading.
    Disk utility won't repair the disk, and the repair disk permissions are greyed out.
    Incorrect number of Access Control Lists
    The volume KYLE-HD could not be repaired.
    Error: Filesystem verify or repair failed.
    Those are what I get when I try to repair disk
    Also for owners enabled, it says no, not sure if that is impt. or not.

    I'm experiencing a similar issue...
    In the middle of copying items from an external drive (ironically, to reformat and enable Time Machine), finder popped up a 'Device Removal' warning... and the two volumes (partitions) of my external HDD disappeared and would not remount. (Disk Utility would not show the drive or volumes.)
    I disconnected, powered down the drive and tried reconnecting - same problem... volumes wouldn't mount and Disk Utility showed no disk (despite the hdd showing up under system profiler just fine).
    Tried again, and got the problems Kylecool is describing.
    Luckily, most of what I wanted to get off the drive had already copied... there's just one more essential (iPhoto library... yes, I have a backup - but I spent a few hours a couple of days ago integrating two libraries into one [a painful process that I don't want to repeat]...).
    I'm in the process of copying the library now, and will then reformat - so hopefully no great loss... but thought I'd add my experience to that of Kylecool's as it may be an issue with 10.5?
    (HDD is connected via FW400.)

  • External hard drive is not working on airport time capsule even after 7.7.2 firmware update.

    External hard drive is not working on airport time capsule even after 7.7.2 firmware update.
    I have the latest Airpor Time capsule 2gb. I specifically bought it so that I could have an external hardrive set up to wirelessly house my itunes library and movies. When i connect the drive, all i get is that the disk needs to be repaired.
    the drive can works fine when connected to the macbook pro and I have run the verify and repair features in disk utility. I have also reset the airport timecapsule as well following these changes and still no change.
    The 7.7.2 update says that it addressed the usb issue of not showing the drives but there are still problems as I cannot get it to appear.
    Please help.
    Thanks

    How is the hard drive formatted?
    Have you tried using a powered USB hub with the drive when it is connected to the Time Capsule?
    (The USB port on the Time Capsule is borderline as far as power is concerned....you may need to use a powered hub.....even if the hard drive has its own power supply)
    If the drive is formatted correctly....and....it has ample power, it will "show up" when you open AirPort Utility, click Edit, then click the Disks tab at the top of the next window.
    In the example below, my Time Capsule drive is named "Backups" and another drive named "WD Drive" is connected to the USB port on the Time Capsule.
    You should see the name of your Time Capsule drive (named "Data" unless you have changed the name) and the name of the USB drive if you perform the same check.
    What do you see?

  • External Hard Drive no longer showing in Devices

    My external hard drive no longer shows up as a device on my MBP. It has worked fine since the day I plugged it in.
    The Time Machine is using the HD, and continues to do it's backups, so power and USB connection is not an issue
    The HD shows up in Disk Utility (The Time Machine portion AND the partition that I've been using for storage)
    I ran a repair on the partition in Disk Utility and it checks out OK
    I can access this partition from VMware Fusion, so the windows side of the MBP sees it, and it's operational
    Used the HD all day yesterday without issue
    I've restarted the MBP to see if it would find the HD partition after a restart, it doesn't
    I've unplugged (USB) and powered-off the HD, and when I power-on, it still isn't seen.
    Any ideas?
    John

    If TM is turned on and it still doesn't show up then do a SMC reset.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
