usb is not recognized

@CountMike - if the drive isn't accessible from Windows, recovery tools won't help..

Hi there
try and see if it's listed when you run DISKPART in admin mode

type in LIST DISK. If HDD isn't shown there then it's probably defective.

Another solution is to plug it into a POWERED USB HUB - even if HDD needs separate power sometimes it still won't work unless a POWERED USB hub is used -- some of those external HDD's can take a lot of power --especially if connected to a laptop.

If that still fails then one more final throw of the dice -- download a Linux Live CD (suggest Linux Mint as it's really Windows like). Boot it up and see if it sees your HDD.

If it does you can recover all your files - copy to another device.

Before doing anything though switch off everything (completely power down and leave unplugged for 5 mins) and then power up computer first with NO USB devices connected (other than possibly mouse and keyboard). Then plug in HDD.

My gut feel is that unless HDD is broken you've got insufficient power on the laptop USB to drive the device.

Try some of these recovery tools, if any of them sees it there's good chance it would recover some or most files. Download Data Recovery Tools for Windows - MajorGeeks
Download Recuva - MajorGeeks seems to work best of free applications.

I know but it doesn't hurt to try. I had cases when it didn't show in Disk Management yet rescue program(s) have seen it. Active partition and/or Easus would also see it. In this case, it's built in controller have probably kicked the bucket or bought a farm as case may be.

it doesn't work
the recovery tools are not detecting it

My condolences, seem like it's dead.

yeah may be
my brother in low told me same thing.

Try making a live Linux USB flash drive or DVD and boot the computer from that. Then plug in your portable hard drive and see if it's recognized. If so, copy your files to a different flash drive or portable hard drive.

If you're not fimilar with live Linux, it's an operating system that runs off the flash drive or DVD. Nothing is written to your hard drive. When you Shutdown, no trace of it is left.

I like Linux Mint because it's very similar to Windows 7. You will have no trouble using it. I read somewhere that the Mate desktop is best for the live version. This is the program I used to make my flash drive.

Universal USB Installer - Easy as 1 2 3 | USB Pen Drive Linux

This is the download for Linux Mint.

Download - Linux Mint

it will change my system?
