Cannot open my external hard drive

Hello

Reinstall everything my laptop with Windows 7. Bought a new Toshiba external hard drive and I connected it. The laptop was able to detect the device, but I can not open the device. What should I do?
Thanks for your help!

It has no letter... managed to get help and apparently I needed to go to the control panel and assign the letter.

Thank you for your answer! :)

  • Cannot open my virtual hard drive

    I tried to create a virtual hard drive, so that I can view and edit files from my backup of Windows from my hard drive.  I have a 'new virtual machine' installed, but when I opened this program, I get this message.  "No startup disk is specified. Although you can still boot from a floppy disk, it is recommended that you specify a startup disk. "I guess my question is" what? "No, seriously, how can I specify a startup disk?  And what start up disc can I specify?  And why is it so freaking hard?

  • Cannot recognize the external hard drive.

    Have an iMac with Parallels and Windows SP installed Pro computer.  Until yesterday, when we had a power outage, I had a Verbatim external disk set on the Windows side of the machine that worked very well.  I the embroidery machine and I keep my drawings on this small hard drive and access it through a software on the side of my Mac Windows.  Since the blackout, my Mac does not recognize the Verbatim.  I tried the Verbatim on another pc and it works fine.  Turned on my Mac, is gone on the side of the window, plugged in the Verbatim... little popup appears asking if I want it on the Mac or my Virtual Machine.  I loaded Virtual Machine.  When I go to my program of embroidery and search the external hard drive, he doesn't "see" it.  Then a box comes up and says "do you want it disconnected from your Mac" and it must be removed by force of the virtual machine.  NOTHING WORKS.  It worked perfectly before and I can't figure out how to get my Virtual Machine (Windows) to recognize.

    Hi gloriajstitcher,

    Check if the disk is detected by plugging it into a different port.

  • Return additional ups cannot find my external hard drive.

    Windows back Ups to run without problem. I put them to run every week and save them to an external hard drive. In recent times the first (full) backup works but additional back weekly, ups can't find my external hard drive even if the settings have not been changed and the first aid found without problem. I use Vista Home Premium.

    Any ideas?

    Thanks John

    I suggest avoid you the Windows backup program and you get a good commercial backup program. This forum meets for a windows problem reports. I know that I was very impressed when I tried it. Two, I'm familiar with and like Norton Ghost (which I use for 7 years without the 1st problem), and Memeo, which has a 30 day free trial and you can buy it for $29.99 - you can download it from

    http://memeo.com . You can get Ghost for almost nothing (like me), if you look at the sales.

    CNET has a lot of reviews of backup program to

    http://download.cnet.com/windows/backup-software/?tag=contentBody;sideBar .

    Some of them are free (the last time I checked there over 300), some have free trials (more), and some are buying only (more than 200).

    Good luck

  • Cannot find my external hard drive in file Explorer

    I can find my external hard drive in the Manager, but not when I go to computer

    This usually means that Windows 7 think that the drive is not partitioned or formatted.  This usually happens as a result of any material event on the external device.  The hard drive itself or the case could fail.  What causes this is:

    1. overheating
    2. a bad USB disconnection
    3. Shock, like a drop of water

    If you need to replace, you will find a few tips here: http://canadiantech.info/?page_id=213

    You should be able to re-partition and / or reformat the disk, but all will be lost that was stored on it.  The tools to do this are in computer management, disk management.

  • Windows 7 cannot see my external hard drive, even if I don't use it on this computer!

    I have 2 external hard drives, both worked well on Windows 7. Now, on the same computer, no change, they stopped from within the computer. Drivers fine and visible in the devices. all ideas

    Hello Gus,

    Windows 7, having trouble finding external drives is not uncommon. I use Aomei Partition Wizard to get Windows to recognize the drive; Download here: http://download.cnet.com/AOMEI-Partition-Assistant-Standard-Edition/3000-18512_4-75118871.html?tag=mncol;1 .

    Once installed simply click on the external drive, and then select Properties. Who should get the drive recognized by Windows. See if that solves the problem for you.

    Kind regards

So yes I did it, but I made using windows 7 have where, instead of download all the files, I just insert the original DVD of WIndows 7, I restart my PC and follow the instructions of recovery of BitLocker recovery key, and voila. The problem is that I've NEVER stored on this particular external hard drive recovery key. BTW: I tried to follow the steps mentioned by Mr. Vijay but inconsistent tool with my operating system (Windows 7 64-Bit) it only works with Vista (not 150 percent certain but close).
