Why cant I see my external hard disk on finder?

I disconnected mt external backup disk without ejecting it first, now it doesn't show in Finder when I connect it. Is there anything I can do?

On a Windows system, on boot up it would say something like -- this disk is damaged and must be repaired. With Mac it just doesn't mount. As Axeman1020 says, I'd try turning the disk off, waiting 30 seconds, turning it on, bringing up Disk Utility and seeing if the external disk is visible. if so, I'd try a repair, or at least a check.
It's rare that the disk would be unrepairable. If it was disconnected while writing during a power surge like a nearby lightning strike, there could be actual damage to the disk and then you might be in trouble. It could be worse, it could be the internal disk/SSD.

  • Why can I see my external hard drive?

    For 2 years or more I've had an external hrad drive to back up my Imac. One day I got a message that there had not beeb a back up for for a really long time  ( I have it on automatic).
    Ever since, I have not been able to see the external hard drive on mi Imac and have not been able to do regular back ups.
    First I turned off, on, restart computer and tried to see if it showed up on another computer, which it did.
    What could the problem be?  It was working just fine.
    Please help
    Thanks

    EHD's can crash. First thing I'd recommend though is to do 2-3 SMC resets. Shut down the computer, then remove the power cord from both the wall plug and back of the computer, wait 15-20 seconds and restart normally and test.
    If that fails use another cable to connect the drive, if that fails open Disk Utility and see if the EHD can be seen. If that fails then replace the drive. I would STRONGLY recommend 2 backups, use Time Machine on disk 1 and then use a create a clone using either SuperDuper or Carbon Copy Cloner on the other drive. When it comes to backing up, redundancy is smart. Would you trust your bank if  they only had one form of backup of all your money??

  • Deleteing files on an external hard disk with finder

    lately i have been having problems deleting files on external hdd with finder cos the file doesn't appear to be deleted, it deletes them into the ext. hdd
    pls how do i make finder delete the files permanetely from the drive?

    When you delete a file on the Mac, you drag it to the trash can. What happens if you force empty trash after dragging the file on the external hard drive to the trash?

  • Why cant i see previews of my DNG in finder (on Mac), I can see previews of my original raw camera files but not when I use lightroom to convert to DNG.

    s

    I am guessing that Apple is responsible for DNG decoding, now, rather than Adobe, although Adobe should still be responsible for keeping their website up-to-date, and not have dead-end pages without any explanation.
    From what I remember, there were some cameras with lens corrections built-in that Apple refuses to show DNG previews of—the DNG Version was too new, but it wouldn’t hurt to check and see if there is a Apple Camera update in case they have fixed this.

  • Can't get external hard disk icons to appear on iMac desk top

    Hi guys,
    I hope someone can help me. I have OS X Lion on my iMac. I noticed that a few days after installing it, my external  hard disk icons and  Macintosh HD icons  disappeared from the desktop. I tried going to Finder- Preferences- Show these items on desktop and checked the appropriate boxes but this only restored the Macintosh HD icon to the desktop. Checking the "External disks" box makes no difference. When I open Finder I can see the external hard disks in the sidebar so I don't think there is a problem with the disks. Can anyone advise me on how to restore the external hard disk icons to the desktop?
    Thanks a million

    I'm not sure why they're not showing but try doing a couple of troubleshooting steps. Restart the machine in the Restore Partition, when you hear the startup tone hold down the Option key and choose the Restore Partition. Then open Disk Utilities and Repair Disk Permisssions on your internal HD at least 2x, while you are in DU it wouldnt hurt to run Repair Disk, again 2x. Then restart the computer in Safe Mode to clear some caches and finally restart normally and check.

  • Access via a network to an external hard disk ?

    Hello,
    My wife can access with her PC (vi$ta) my Mac's Public folder through our router but she can not see my external hard disk, an alias does not help.
    So each time I have to move files from my external HD to the Mac.
    The inverse solution, me dropping files on her PC is "not possible", we can not, I have to work too
    What should I do to give her a access to all the external HD or to some specific folders on the external HD ?
    To connect to my mac she has to login, I would like to keep this for security reasons.
    Thanks a lot.

    You can add a share point - for Tiger, a handy utility to use is SharePoints (Leopard has this feature built-in via the Sharing preferences).

  • I have the latest Mac Air 13" and I have a Seagate 500MB external hard disk I cant copy or Cut any files on the hard disk and I cant even delete any files. I have the settings as Read and Write in the get info tab. Please help

    I have the latest Mac Air 13" and I have a Seagate 500MB external hard disk I cant copy or Cut any files on the hard disk and I cant even delete any files. I have the settings as Read and Write in the get info tab. Please helpand also note that my hard drive was formatted on a Windows 7 Laptop.

    thats the problem, its in MSDos (Fat) or NTFS for Windows.
    Options.....
    1. offload all that data on the HD onto your PC, THEN format the HD in EXFAT for use on BOTH PC and Mac for read/write.....then reload all (or as you need) that data back onto the HD
    2. get another HD, and format it for Mac OSX extended journaled.
    FAT32 (File Allocation Table)
    Read/Write FAT32 from both native Windows and native Mac OS X.
    Maximum file size: 4GB.
    Maximum volume size: 2TB
    You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
    NTFS (Windows NT File System)
    Read/Write NTFS from native Windows.
    Read only NTFS from native Mac OS X
    To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
    For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
    Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    Maximum file size: 16 TB
    Maximum volume size: 256TB
    You can use this format if you routinely share a drive with multiple Windows systems.
    HFS+     ((((MAC FORMAT)))  (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)
    Read/Write HFS+ from native Mac OS X
    Required for Time Machine or Carbon Copy Cloner or SuperDuper! backups of Mac internal hard drive.
    To Read HFS+ (but not Write) from Windows, Install HFSExplorer
    Maximum file size: 8EiB
    Maximum volume size: 8EiB
    You can use this format if you only use the drive with Mac OS X, or use it for backups of your Mac OS X internal drive, or if you only share it with one Windows PC (with MacDrive installed on the PC)
    EXFAT (FAT64)    ------Can read/write from both PC and Mac
    Supported in Mac OS X only in 10.6.5 or later.
    Not all Windows versions support exFAT. 
    exFAT (Extended File Allocation Table)
    AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    Maximum file size: 16 EiB
    Maximum volume size: 64 ZiB
    You can use this format if it is supported by all computers with which you intend to share the drive.  See "disadvantages" for details.

  • Why can't I see my external hard drive, Intel iMac / 500 GB, G-Drive

    Why can't I see my external hard drive?  I have a new iMac, Intel based i5, running Lion (2-3 months old).  I have a 500 GB G-Drive external hard drive that has showed up when connected to my iMac for the past 2-3 months.  Now it's gone.  It's NOT visible when using Disk Utilities.  I have all of the radio buttons chosen in the Finder Preferences.  I've unplugged and replugged in the drive, have switched the cable ports and have switched firewire cable.  The G-Drive powers up and whirls, so I don't believe the problem is with the drive. Yes, I set my Preferences to make sure ALL disk types are visible.  I've restarted my iMac on a number of occations.  I rest my SMC by totally unplugging my iMac for a minute, then plugging it back in. Any suggestions?

    Unplug the HD, Zap the PRAM, reconnect the HD, power it up, and see if that fixes the problem. If not, then maybe the HDs bitten the dust. Try on another computer to verify.

  • Finder/Desktop not recognizing/seeing external Hard Disks

    For 2 weeks, I've used two external hard disks for Time Machine. Both have Mac partitions, with GUID Partition table, and Mac OS Extended (journaled) format. Things worked for 2 weeks.
    Then today, the Mac wouldn't recognize one of the Hard Disks, i.e. the disk icon does not appear on the desktop, and the Disk Utility does not see them either.
    I thought the problem was one of the disks, so I attached the other disk, and that one doesn't appear on the Desktop or Disk Utility either.
    Concurrently -- and I don't know if these issue are related -- I see that the iMac doesn't seem to turn on automatically when I press the on-button. Instead, I have to keep it depressed for a long time before it comes on.

    A few hours later, it started working again. No idea why it happened, and no idea why it resolved.

  • I am a OS10.7.4 user. yesterday i bought a Lacie external hard disk but error message appear said " You cant open the applicant LaCie setup assistant because PowerPC applicants are no longer support". please help me how to connect my mac with Lacie??

    i am a OS10.7.4 user. yesterday i bought a Lacie external hard disk but error message appear said " You cant open the applicant LaCie setup assistant because PowerPC applicants are no longer support". please help me how to connect my mac with Lacie??

    You do not need the Setup Assistant; in fact, you do not need any software on an external hard drive. I have two LaCie's; I erased the drive as soon as I plugged it in. You will need to format it anyway because most hard drives come Windows formatted. So, if you only want to use it with the Mac, highlight it in Disk Utility and choose Mac OS Extended (Journaled) as the format and the GUID Partition scheme under Options. While doing that, it will erase the drive (and get rid of the LaCie software) - once finished, your drive is ready to use for Time Machine or any other backup plans you have for it.

  • Cant write/edit data on my external hard disk! Help please!~~

    Okay guys, currently, i'm using Tiger version 10.4.11. My problem is that i cant edit data or write data to any external hard disks, like the maxtor One Touch and so on. Only thing i can do is to extract the data from the disks. I have tried to write on multiple hard disks but in all my attempts i have failed. i've tried to edit my network settings, but no results.
    So, i seek help from anyone out here!

    Hello, yea.. thanks man =)
    Basically, its a shared hard disk between my macbook and a windows PC. So i kinda use the PC to write all my backups and data on the hard disk.
    I have quite a few hard disk and they all have the same issue. It says 'The item 'file x'cannot be moved because 'my hard disk' cannot be modified.'I've used the software provided from the hard disk manufacturer, Maxtor/Seagate, to reformat the brand new portable hard disk which i bought yesterday.
    Its connected via USB, same as all the other ones i have.
    eh. the get info for it says
    Kind: Volume

    erm... its a portable drive which i carry around, so i guess its not a network drive? and how doi determine the network settings? Sorry man.. not really good at these =x

    You can do a search of an external drive if the OS permissions are OK.  Bridge will not search across different drives however.

  • Mac Pro Notebook to see, read & write to PC Windows 7 External Hard Disk NTFS

    Hi
    I have a Windows 7 PC desktop with an external hard disk coonected to it by USB formatted as NTFS. Is is connected by cable to a wireless router.
    I now also have a Macbook Pro.
    I would like to work on jpg and Raw files on the External Hard Disk both via the desktop (as I currently do) and also now via the Macbook using Photoshop Elements which exists on both.
    Is there a way that the Macbook can read the external drive and read and write the same files as the pc without purchasing a Macdrive and reformatting the External Drive?
    Thank you
    Regards
    CGJ

    Hi everyone
    I've managed to work out how to share my desktop and the external drive attached to it via wireless so my Macbook Pro can see, open, and edit and save photo files via Photoshop Elements.
    I can also then view and edit them through the Windows PC - though they say some properties are missing this I can live with.
    Therefore no re-formatting needed, and no downloads either.
    Many thanks
    Regards
