I have an external USB 3.0 HP Portable hard drive (pd1000a) that has stopped working correctly. Whether I connect it to my laptop or my desktop (front or back USB port, 3.0 or 2.0 port - tried them all), it is recognized, but then when I try to copy the files off it, either I get a message saying the files aren't in that location anymore or "An unexpected error is keeping you from copying the folder. Error 0x80070037". When I go into Disk Management, it shows as a healthy partition, and I did try assigning it a drive letter. I've tried running a scan disk but it won't run - just doesn't do anything. Power management for all USB-related items is turned off. Both laptop and desktop are Windows 7 Pro, 64 bit.
On my laptop, it was constantly disconnecting and rediscovering the drive. On the desktop, it managed to stay connected and the light on the drive remained solid, but as soon as I copy the files and then hit paste, it comes up and says the files are no longer there.
I haven't tried a new cable b/c I don't have one and didn't think that was the issue but I certainly can pick one up at Staples if it sounds like a cable issue.
Is there any way to get the files off the drive? They are mostly jpg and camera raw files, if that matters. Thanks so much in advance!
