Why won't my computer list or open my 500 g external hard drive

I bought a external hard drive I put movies on it and some work data, I plugged it into the usb port thinking it would play the movies on my Blue Ray player, it didn't (a storage stick will so I thought this would work the same way) when i plugged it back in to the USB port on my computer it no longer comes up as an icon in my computer and if i go into devices it says everything is working fine but the external is not recognizable by the computer, it will not open .

When you say that it is Not Recognizable

What exactly do you mean?

Have you looked in Drive Management to see if it shows there?

But most likely the Partition Information got Corrupted when you unplugged it from the Blue Ray Player as you can not dismount drives from these devices. You should only use devices with no moving parts in USB Sockets on things like DVD Players. If you use a HDD there is unlikely to be the the correct components in the DVD Players to be able to read the HDD in the external Case.

Particularly with a 500 GIG HDD which has to have a NTFS Partition and not a FAT 32 Partition. I would imagine that the Partition Type is not Recognized by the Blue Ray Player hence the inability to play from this device.

As for recovering your Drive you can open the Drive Management in your Windows Computer and Format the Drive to get the computer to recognize it again or if you want/need to recover Data off this drive and it is Important as apposed to just being Nice to have back you should pack it up and send it to a Specialist Data Recovery Company and pay them to recover the Data.

However if it would just be Nice to have the Data back you can try the following.

Start off by ruining testing the HDD with it's Makers testing Utility. You can get this from the Drive Makers Web Site.

if that doesn't work try running chkdsk /x where X is the Drive letter from the Command Prompt.

If none of the above works you need to attack the drive with some form of Data Recovery Software.

Here is a short list of the better ones














While the last 2 are from the same company they are very different products. Win Hex should only be considered foe use by someone who knows Hex Inside Out while Davory is a great cheap General Purpose Application.

Personally I prefer the On Track Option but it's anything but cheap. However because I use this type of software a lot it's paid for itself many times over by now, for a cheaper option Spin Rite from Gibson Research or Stella have both very good reputations by other TR members.

But be Aware, the more you unsuccessfully try to fix this the more expensive a Data Recovery House is going to be and the less likely they are to be able to recover all if any of your Data.
