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.
Checking Catalog file.
Invalid index key
Rebuilding Catalog B-tree.
The volume Jon & Sarah Time Machine could not be repaired.
Error: Filesystem verify or repair failed.
Verifying volume “Jon & Sarah Time Machine”
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid index key
The volume Jon & Sarah Time Machine needs to be repaired.
Error: Filesystem verify or repair failed.
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.

    My La Cie Porsche Design External Hard Drive USB 3.0 is no longer working with Time Machine.  Is Yosemite the cause?  How do I fix?

    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.

  • My external hard drive is not working on my mac.

    I have tried all options available such as going on finder and making my hard drives visible and disk utilities

    Basically my external hard drive would not eject so i force quit it and the hard drive does not come up at all anywhere on my mac pro OS X version 10.9.4 and it isn't visible in disk utilities no and it doesn't say format either and i have tried it on a windows computer it does not show on their either. the format is Fatdos i think so i can use it on windows and mac and i cant see anything in system reports and yes it is connect by a USB. also it isn't making any noises either

  • 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 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

  • WD 1TB External Hard Drive won't work with Snow Leopard

    Hi all,
    I recently purchased a Western Digital 1TB External Hard Drive. It came formatted for Windows with NTFS, but I didn't think this was a problem as the packaging stated it could easily be reformatted for Mac OS. To cut a long story short, it couldn't. When I plugged it in to my Mac (iMac 21" i3) and tried to use Disk Utility to reformat it, partition it, whatever, it just wouldn't work always returning some sort of error. I resorted to using a Gparted Live CD and succesfully formated it to HFS+ but yet when I plugged it into my Mac it wouldn't mount the disk. After following advice to let Disk Utility 'Repair' the disk, this is the output:
    Verify and Repair volume “external”
    Checking non-journaled HFS Plus Volume.
    Checking extents overflow file.
    Unused node is not erased (node = 1458) [In red]

    The volume external was found corrupt and needs to be repaired. [In red]
    Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. [In red]
    If anyone knows what this means, and more importantly anything I can do to try and fix this, I would really really appreciate the help!
    (Obviously I see it says reformat the disk, but this is easier said than done. Now Gparted crashes when it tries to read it and Disk Utility hangs indefinitely if I try to do anything to it)

    I believe the reasons behind this must have something to do with the errors highlighted by the repair process (as copied above)- errors I don't understand.
    Disk Utility can't repair NTFS volumes.
    If the drive is not seriously damaged ...
    Go to Disk Utility
    Click on the external Drive (not on the existing partition)
    Click on Partition section in Disk Utility
    In the Pane under "Current Scheme" highlite the Partition and then click the "-" (minus) sign down left.
    Click on the dropdown "Current Scheme" and choose a matching scheme
    On Format choose "Mac OS extended journaled"
    Click "Apply"

  • 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?

  • External hard drive doesn't work on other macs.

    So I've got this external hard drive (WD Elements) and basically have only used it for my macbook pro.  Today I tried it with an imac, and it didn't work.  The computer recognized it, but it wouldn't let me move any files onto the hard drive.  There was no error message or anything; it just didn't work and made that ping sound.  You know the one you get when you clicked somewhere you weren't supposed to?  That sound.
    I thought maybe it was a formatting thing, because the disk utility verification said it's "formatted for use in Windows 7," but then how is it working on my macbook?
    Anyway, I feel like there's a really obvious solution for this, but I can't seem to figure it out, so any help would be greatly appreciated.

    It sounds like your hard drive is formatted NTFS, Mac's can read those type of drives, but unable to write to them without special software.

  • 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!

  • I was using an external hard drive to store video with my MAC. I absent mindedly connected the external drive to a Windows PC and now my mac will not recognize the video files.

    What did you do to the drive while connected to a Windows PC?

  • My External Hard Drive Won't Work With Final Cut Pro

    Hi everyone! I occasionally use my external HDD for Fianl Cut projects, but only when I'm done editing it. While I'm editing the project, I keep it on my SSD. My external HDD has 3 partitions, one for storage, one formatted for windows storage, and the last one is a Mountain Lion Recovery. When I plug in my external HDD and start FCPX, only the recovery partition shows up.. Any ideas? My pimary hard drive storage with the projects is case sensitive, but the recovery is not.. Thanks!
    Btw, I blurred the video and took out the names to protect privacy. As you can see, my internal SSD and one partition on my external show up, but the "1TB HDD" partition does not.

    I connect my bus-powered HDs (more than one) to the iMac all the time without any problems. I have found, though, that for me the FireWire enclosures work much better (faster and more stable) than the USB2 ones. I have had the USB2 drives freeze my computer once or twice when I connected the HD, but nothing like that has ever happened with the FireWire connections. (I switched the same disk from USB to a FireWire enclosure, so all other elements were kept constant in my experiments.)
    One of my HD is in a MacAlly 2.5" enclosure that offers both FireWire and USB2. The other one is in some generic enclosure with only USB2. Both are bus-powered and both work fine.

  • 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.)
