• Managing disks in Windows 7 does not recognize external hard drive

  It is a recent event. I backed up my computer only 45 days ago and it worked Ok. The same external drive has no problems with your Windows XP desktop.

  No other USB devices is facing this problem.

  Device Manager identifies the mass storage device (WD1140), as well as the USB controller.

  This utility cannot sort.
  It is not possible to change/assignment of a new letter to the reader as disk management does not identify her. I also tried to use the command-line (list disk)... the only disc that displayed is internal.

  I tried to change the USB port, without result.
  The operating system is Windows 7 Starter.

• Mac Mini does not recognize external hard drive

  Hello!

  I have a weird question on my Mac Mini. I have two Seagate to 8 external drives connected via USB to my Mac Mini (mid-2011 with Maverics). The discs worked well, but suddenly one of them will not be recognized by the Mac Mini.

  I connected the hard drive of my MacBook Pro and an old PC and it works fine and all files are available, but for some reason, my Mac Mini will have nothing to do with her anymore.

  It does not appear in the finder or disk utility. I unplugged the hard drive for hours and then tried to plug it back without a bit of luck. I restarted the Mac Mini on several occasions. I also tried to connect it to all the USB ports on the Mac Mini. When I connect it to the USB ports, there is no whisper sound indicating that it has started working. However, no sign of it on the Mac Mini.

  It's like the Mac Mini has decided to ignore the external hard drive, no matter what I do. Seeing this works on other devices, I'm fairly certain that the problem lies in the Mac Mini.

  I'm no expert, so any help will be very valuable for me. And if you are kind to help, please explain it to me like I'm 8 or 93 years old.

  Thank you.

  Are these drives powered independently or they depend on USB power?

• Satellite C50-B-131 does not recognize external hard drive

  I used an external hard drive to back up my data. Suddenly my laptop (C50-B-131) says it does not recognize the device. Any help is welcome. I tried to uninstall and reinstall the driver for the drive.
  Thank you

• Vista does not recognize external hard drive (LONG!)

  I bought a Terrabite Cavalry USB Mass Storage 1 unit some time around January 2009. We used it to back up my computers portable wife and daughters without any problems (it was Windows XP a Windows Vista). Shortly after, we have tried to back up my desktop computer, also running Windows Vista, but my computer does not recognize the drive into any USB port. After this attempt, we get is more willing to work on any computer. We contacted the cavalry and they replaced the drive, but we lost a lot of data since most of the files saved on my wife and daughter desktops have been deleted to clean up their hard drives.
  When I received the spare drive I backed up my computer with no problems.
   
  We moved from NC to PA in August of last year and had packed the new car. Recently, we unpacked and used to transfer ALL the photos of my wife, numbering several hundred, again with no problems. In addition, she has saved his computer using the Vista utility. Today, I made the horrible mistake of trying to back up my computer using the same player. I had completely forgotten the previous question. Yet once, my computer did not recognize the drive, any USB port used or on the tabs 'computer '. When the drive is plugged in and turned on, it will be not even allow us to display the elements on the tab 'computer '.
   
  And now, just as before, the player no longer works on my wife's computer either. THIS IS AN ESSENTIAL QUESTION! If we cannot access the drive over 500 photos of our family, covering more than 5 years are lost forever!
   
  Although I've read similar questions on this site (especially in regards to Windows XP) I can't find the one that is exactly the same problem as this.
  There is nothing wrong with my computer. Each USB port works fine. I tried other USB devices with no problems of any kind.
   
  On both computers, if you connect the external drive and the power up it starts with a light blue on the front as it is supposed to. He then became red and Windows makes the normal audio alert, as it does with any USB device plugged. On the bar, the new icon 'Remove hardware safely', says but clicking on that alone causes the computer to get ung place intil the drive is unplugged. The same is tru if we try to access the tab "Computer" in the Start Menu. The computer attempts to load the itms 'Computer' but never the completion of the task. THE TWO COMPUTER DO EXACTLY THE SAME THING! My wife uses a Dell with Vista Home Premium and I use an EMachine with Vista Home Basic. And this issue seems to happen only after using his computer to mine, not the other way around because I had done a backup on thise drive when I got last year and she just did a new now on his own.
  I wrote to the Cavalry, but received no response. They said the last time that they aren't able to recover lost data, and it is said that all over their site.
  The external drive is a cavalry model # CAXP3701PA.
  Someone please help! Pictures of our last five years (including photos of my wife of his precious Golden Retriever from puppy to now) are lost if we cannot solve this problem. It seems that the player works well, but something corrupting of the software driver. We tried again to my wife's computer o and it begins with "Download driver software for device" but then what I described before using it.
  Any suggestions would be greatly appreciated.

  Hello

  Put the disc in a real store of the computer (not the leeks and the glances at a Best Buy or other stores)
  and they can remove the drive from the case and put it in another computer to back up data
  to other media. Of course this cancels any warranty and may not work if the drive has probably
  in fact failed. Data can often be recovered since a failed drive while it's expensive.

  (The drive could be put in either your PC as a 2nd drive).

  I hope this helps.

• Windows 7 Starter Edition does not recognize a hard drive WD

  Windows 7 Starter Edition does not recognize a hard drive WD, I used until last month. Device Manager sees it, he sees the USB controller (it lists as a mass storage device), but I can't access the information on the hard disk, or make use of the last backup. I tried to uninstall USB drives - it is not the thing. It gets listed under disk drives.

  Thanks for the reply.

  There was no error message: the device has been recognized (listed) by the USB controller and the Device Manager, but not by the management of the disks - so I couldn't access.

  I managed to fix the problem after:

  -J' scanned the computer (DELL Inspiron) with the Safety Scanner
  -J' completely uninstalled all the software associated with an external hard drive
  -J' uninstalled the USB controllers
  -reboot the system
  -reconnected the external HD
  -After gaining access to the drive, I installed the dedicated software

  Best regards

  Hi all
  I need help with my laptop, please...

  My problem is,
  I have a notebook by Satellite A200, and the operating system is Vista, am not satisfied with Vista at all so I bought a Windows XP bootable CD... When I tried to install it it gave me a massage that he could not recognize my hard drive...

  I checked the Web from Toshiba site and downloaded the files from the storage for XP Manager as someone told me it could be the SATA problem and you must apply on your hard disk for XP will see it?

  The question is:
  How much is real?
  How can I install XP on my PC now?
  can I install Storage Manager while I'm on Vista and then install XP?
  I put the Storage Manager on a CD and boot from it?

  am really confused because when I extracted the Storage Manager and view the files I found the setup button and a few other folders, and I do not know what those to use because I don't know what is my hard drive... and any help will be much appreciated

  Thanking you a lot in advance

• Tecra S3: Installation of Vista does not recognize the HARD drive

  I try to install Vista Ultimate on my Tecra S3, but installation does not recognize the HARD drive.

  I tried to find the driver for Vista for my computer, but not found RAID.
  Tried it with XP drivers, but no longer works.

  Do you have an idea where I can download Vista drivers for RAID?

  THX

  Hello

  Your suggestion is good. The Tecra S3 supports the RAID, and the RAID driver is required to install the OS on the HARD drive.
  On the European driver Toshiba page I found a RAID for XP driver.

  I put t know if this driver will run under Vista, but I recommend to test.
  The RAID XP 1.3.8.0 driver version can be downloaded from this site:
  http://EU.computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp?service=EU

  Please note; You can store the RAID driver on an external USB and Vista should recognize it!

  Good luck

• Seagate Free Agent Desktop does not recognize my hard drive in Windows 8

  My Seagate Free Agent Desktop does not recognize the hard drive on my new computer with Windows 8. Although I can still use it to save and transfer all the data from one to the other, I lose the functions in the menu of the Seagate such as backup and synchronization. It worked fine on my old computer that worked on Windows XP. I tried Troubleshooting compatibility mode and that did not help.

  The message in the Seagate Manager appears as:

  None of the external drives have been found. Make sure that your external drive is connected and turned on.

• Reference Dell E1505 laptop - not recognizing external hard drive

  I bought a Dell Inspiron E1505 year last with Windows Vista and just bought an external hard drive laptop ( http://www.toshibastorage.com/main.aspx?Path=StorageSolutions/ConsumerStorageProducts/NewUSBPortableExtHardDrive ) from Toshiba a few days ago.

  My Inspiron E1505 does not recognize the drive.  I went to the Device Manager and the Toshiba drive does not appear.  However, the Toshiba portable external hard drive is recognized by my new laptop Dell XPS with Windows Vista.  I called Toshiba tech support and they said there is a problem with the operating system does not recognize the hard drive.  Anyone know how to solve this problem so that my Inspiron E1505 will recognize the Toshiba portable external hard drive?  The drivers are built into the Toshiba external hard drive so tehre are no drivers to download.

  
  

• Dell Inspiron 531 s problem of power/does not recognize the hard drive

  My Office does not illuminate. I replaced the power supply. No, it powers on but does not recognize the hard drive. It gives an error as SATA 0 None SATA 1 no SATA 2 No. How do we know that the cables are properly connected. I feel like I'm very close to solving the problem but don't have a clue what that next step to follow

  The original PSU had 4 sets of cables and connectors.  The new power supply has 5 sets of son.

  From your post, I guess that the configuration of the system now recognizes the hard drive?

  If you do not have a floppy drive, then BIOS can find the player who isn't there, it returns this error.

  Make sure that the floppy drive [drive A] is disabled in the [BIOS] installation system, page 173, so that it is no longer looking for the disc and see if this stops the error message.

  If the hard drive is recognized in the configuration of the system, he now knows in windows "My computer" or in "disk management, [right click on 'My computer' and select 'Manage', then disk management]."

• Satellite A205-S4777 - XP does not recognize the HARD drive

  Hello!

  Recently I buyed a new satellite Toshiba A205-S4777 with Windows Vista home premium installed

  I want to directly install Windows XP but the installer does not recognize the hard drive or more exactly controllers!

  I nLite Sata drivers in Windows Xp Sp2, I bought on the microsoft.com site!

  The Installer recognized fine hard and Setup finallased!

  But here's the problem when loading windows and try to pass on gorge yourself sort of blue screen one unreadable!

  And restarts and let, it does all day the same thing!

  I'm afraid that I have not nLite the right drivers.

  Is there anyone Heve downgraded this model?
  Thanx

  Hello

  Maybe you did not use good SATA driver?  :| Who knows
  The point is that there are two different versions of Intel Matrix Storage Manager supports different chipsets.
  I put t know what chipset is in charge of your laptop but you should check this and must also check the description of the Intel Storage Manager and check what chipsets are supported.

  In addition, you should have a look here in this doc from Toshiba:
