external hard drive "went missing" during normal operation

I usually keep my computer running most of the time, turn off updates (as they charge for this), or because of a problem that I get with my external hard drive. Randomly, professional Vista continues to recognize its existence. The hard drive is still plugged in, turned, and so forth, but he claimed not to be there. It is not even appear on the window of my computer... It is starting to really bother me, as can happen when I fell asleep with my laptop for background noise (music) and music will leave just about me or when I'm working on a project in Photoshop, and I can't access my images to use.

I can't just scrap what is on the disk hard to reformat, it's almost his TB limit and I don't have the space to save a lot more information on my intern.

  • external hard drive is missing. But drive turn on!

    Hello

    My Iomega external hard drive seems to be missing on my mac. But I see the drive light on when you are connected to the USB port.

    I use an old iMac & an Iomega hard drive that worked without problem. I took travel & when I got home, I connected on the iMac, but I don't see the icon. I find deposit on Finder & also I tried turning / slideshow, external drive on Finder.I see all other connected external drives but not this one. I do not see it listed in the disc utilities. I tried to connect to another Mac & still have the same problem. Can someone tell me what is happening?

    I've never used the Iomega drivers on the mac, but everything worked well. Do I need to download Iomega drivers?

    It seems that the Iomega company is more then what I do and who should I speak?

    I use the last BONES of El capitan.

    Any guidance will be appreciated.

    Thank you.

    If possible, try a different port or a different cable; the light in the external hard drive enclosure

    can work OK, while the data flow uses different threads in the cable. In addition, the housing

    (also known as speaker) can have bad elements which could affect the ability of

    the internal hard drive. You may need to get a replacement suitable for box

    Use with this hard drive inside.

    The old drivers of this company would be unnecessary; the recent OS X has all the people.

    There are several reasons why the external drive may be badly behave. Between the

    cable, taken & /or port and failure internal circuit that connects the drive

    inside the computer outside, these can be remedied by the use of replacement cases.

    So there are words that can mean 'wardrobe' of 'accommodation' - or "case."

    If the unit is based on port-power supply through the USB cable only, other issues can happen.

    Most of my closed external hard drives use an external power supply. You can

    must obtain and use (please bring extra) quality additional backup included the HD discs.

    For examples, see OWC macsales.com. Specifications and information are here.

    Sometimes, you can use disk utility to see if you can get an external drive to be 'seen '.

    and if so, do 'mount' - sometimes the other question, trying to unmount or eject.

    At this point, close to 12:30, I hope the case is something simple. A cable? A port?

    In any case...

    Good luck & happy computing!

  • Seagate external hard drive / / no display

    Recently I bought a Portable Seagate 2 TB external hard drive for my MacBook Air. I put all my movies, music, ext documents on my hard drive with my important homework. The reason why I did was reset my mac, then return all my old documents, photos ext, back to their place of origin. I have managed to do and frees a lot of space. A few days after my MacBook fell asleep with a connected external hard drive and now the hard drive is no longer present on the desktop or in finder. I am able to find in my "disk utility" , but for some reason, it shows the hard drive passed out faded gray and full? I tried to hook up with different cables and on the various devices as well. Also sang the first aid option in "disk utility" with no other results. I have contacted apple support and found out it was the external hard drive with the problem, so they couldn't help me. They then redirected me to Seagate Support, and I had already tried the methods they gave me (see list above). I was wondering if anyone here on communities of Apple has experienced the same problem as me, it would be that much appreciated advice you may have. I have important files that I need to recover.

    Help, please!

  • External hard drive USB on Time Capsule

    Hello

    I have an external USB hard disk and plug it into the USB port of my Airport Time Capsule makes it accessible wireless (if on the sidebar of the window under the section 'sharing' I click on the Time Capsule to enter airport name next to his record 'data', I also have a folder with the name of my USB HD and I can access).

    Now the problem. I have a USB external hard drive, I can access normally connect my iMac or iBook portUSB one, but, if connected to the time Capsule... nothing happens.

    So there must be a difference in the two external hard drive. What a difference creates the problem, why and what I can do is my question.

    Can someone help me?

    So far, here is what I found to be the similarities and differences:

    The two serial ATA, 2 to, partition GUID mapped external USB hard drive.

    In disk utility, one that is visible on the Time Capsule is displayed as 'external HARD disk support' physical disk with OS X extended physical volume. One who isn't appears as physical disk 'external media' with logic extended OS X volume.

    Hi Ranmaboy,

    I understand you have two external hard drives USB that you want to connect to your airport Time Capsule via USB, but one who is not recognized by the Capsule from the airport. Given that this player connects to your iMac without problem, I would recommend that you backup all data stored on the disk, and then follow the steps here to re - format the drive using disk utility:

    Backup disks, you can use with Time Machine - Apple Support

    Format a drive connected to an AirPort Extreme 802.11ac or Time Capsule

    If you are using an AirPort Extreme 802.11ac or Time Capsule, you can connect an external drive to the USB port on these devices for use with Time Machine. Follow these steps to reformat the hard disk in the first place, it is ready for use.

    1. Connect the hard drive to a USB port on your Mac.
    2. Open disk utility.
    3. On the left side of the disk utility window, select your external drive (or one of its partitions).
    4. Click the delete or delete button on the toolbar.
    5. On the Format menu, choose Mac OS extended (journaled).
    6. Type a name for your drive, and then click clear.
    7. After that the drive is deleted, close the disk utility window.

    Once the disk has been reformatted, try to connect this back to the airport Time Capsule to see if it is now recognized.

    Have a great rest of your day!

  • When you try to create a system image on an external hard drive, I have an I/O error ox8078002A.

    I use an HP Pavilion dv7 notebook PC and a 3 TB of Seagate external hard drive USB 3.0.  Operating system is Windows7 64 bit.  Support Microsoft suggests running chkdsk /R on the Seagate drive and I am currently doing this (time consuming).  Another post suggested trying another USB port, but producing the same result.  Any other suggestions?  Thank you.

    I consulted the Seagate Support site and learned that the backup drive Seagate Plus will back up only data, not file system.  He is going back to the store.  Thanks to those who tried to help him.

  • HP ProBook 450 G: drive recovery on external hard drive

    Hello!

    I had a few questions.

    I have a HP ProBook G2 450 with Windows 8.1 now, I wanted to create a disk recovery, but on an external hard drive. Is it so that it is not possible to put it on an external hard drive? When I try to make a recovery it says I should use one with at least 16 GB USB Flash drive. So this means that I could not even do a DVD recovery disc?

    And I would also know, if I put teaching 10 Windows (as our University offers), is possible later use the 8.1 Windows recovery disc to return to 8.1?

    Eager to help!

    Marta

    Hello

    Please use a few DVDs or good USB. The USB will be write-protected therfore no point to use the external HARD drive because you will not be able to use your external HARD drive, only read. Normally, you have 2 options: use of DVD or USB.

    Yes, you can use recovery media to go back to your orginal Windows 8.1.

    Note: you can create recovery media once.

    Kind regards.

    You can not install Windows 7 on an external drive. Windows 7 requires that install you it on an attached storage device internally. What you can do is to back up your current installation of Windows 7 on a hard drive external. Install a new hard drive, then restore the backup of this drive. To learn more:

  • My external hard drive missing from my computer

    Hi everyone is smarter than me... which would include about each of you.  ;-)
    I have a Western Digital 1 TB external hard drive connected to my laptop Dell Inspiron 6000 Intel Pentium clocked at 1.86 GHz proc running Windows XP V2002 Pro 32 bit SP3. Until a few days ago the WD is working fine since I bought it about 3 years ago.

    The problem: the drive is listed in the device as Manager works fine but it does not appear in my computer. I reinstalled the WD software and run the diagnosis that came back with a mistake or two test and repair but not yet in MyComp. I searched the entire computer, but the E: drive is not there. I have studied this thing to the end, including the proposed solutions on Microsoft here, but I am against the wall and do not know what else to do.

    Any suggestions?
    Thanks in advance!
    Mike

    Me = SHOUTING, CHEERING, YELLING, CELEBRATING, essentially going nuts!  :-)

    Guess what, y ' All? I found my Western Digital external hard drive!  I'm so excited!  I was not happy that since my children were born.  Laughing out loud.

    AND I OWE IT ALL TO TECH-GEEK! THANK YOU 1 BILLION, JILLION AND GAZILLION, BILLIONS OF TIMES!

    Your post today mentioning external hard drive to your customer and how you had retrieved all the data using http://www.cgsecurity.org/wiki/TestDisk, it's what saved my life! I spent very little time on their site and very little time running of the programme and BING POW ZOOM! My drive is back, fully intact, not a single missing file!  I think it's all because I was able to give the drive a name (you know, L for logic and so forth). Because as soon as I wrote the files on the disk - which literally seconds - restarted, and BINGO! She's back in my computer!

    I can't begin to even formulate words to properly express how I am grateful to you, TG. I am most grateful. Can I make a donation to your charity in your name?

    A BAJILLION THANKS!

    I went in lightroom and can't find my photos. I lost the link before and did the right click to find and they have been found, but it's different.

    I bought an external hard drive and copied some elements but did not cut their.  I did a back up on my external hard drive, but even once did not move them. I did the simple troubleshooting and it doesn't work.  I'm trying to find the original by right clicking the? on the folder LR and once I find the file it tells me that Lightroom has this file already in the catalog - and I want to merge. I tried one and it disappeared or moved. Help!

    Use the file Explorer to see if the images are still in their original location. I suspect that move instead of copy them. This can happen if you drag you the.

    I found that it is best to use either right click on a file or folder name and select copy then right click on the drive-destination folder and select Paste or use keyboard shortcuts to copy and paste folder and files from one disk to another. The keyboard shortcuts are the CTRL + key C to copy and Ctrl + V to paste in the selected destination folder-drive.

  • RAW files missing changes after moving to an external hard drive

    Hi, I use lightroom 4 and I cleaned a part of my images on my laptop and then exported in JPEG files. My hard drive has started to fill up, so I moved all my files on raw on an external hard drive but now when I come back to make adjustments to these images it tells me that the file is missing. How the raw return file so that it shows the changes I made?

    The changes should have been stored in the catalog file or in an XMP Sidecar file. Also moved the XMP Sidecar files. These XMP files can be marked as system files in OS X, and unless you have show system files (which, with OS X for that option and turn it you may need to use Terminal), and or display all files, Finder can hide on your part.
