USB Mass Storage Device Problems

Sorry my mistake.

Detrolord sorry I got lost is the shuffles.
Are you still having problems?
Did you check and see if this laptop is using UEFI bios and if Safe Boot is engaged.
Have you tried to use any other drive in the USB port on that computer and did it work?

I'm not sure about the UEFI bios but i used 3 potable HD they all don't work well SD card work

If I might start by clarifying a couple points
1. The SES driver is only required if you want to uses WD's "extended" functionality for their USB drive. It's not needed if you want to use a WD drive as a standard USB disk

2. USB Mass Storage and MTP device are different devices (by definition) and use different drivers.
> USB Disks and CD/DVDs are USB Mass Storage devices
> A camera or phone may have an option to look like a USB disk or an MTP device. Each option uses a different set of drivers. A USB device might be able to look like one or the other but not both at the same time. MTP doesn't use the USB Mass Storage driver

@Detrolord
Go to device Manager, right click the problem USB Mass Storage device, select Properties, click the Driver tab then Driver Details button

You'll see a set of driver files. Do you see more then one? Click each file to see if it is digitally signed or not. Report any file which isn't signed

ok its only ony and not digitally signed

I believe that's your problem ("not digitally signed" was Windows error message complaint for the device :) )

Either the .sys file is corrupt and/or you're missing the .cat file that provides the driver's signature. In either case, will have to follow up with you a bit later

ok ty

Oh. One quick question: I may have missed it earlier but are you running 32 or 64 bit Win 7?

64 bit win 7

Instead of fighting with the laptop that may have a bad usb port, or corrupted usb stack, I would take out the hard drive and put it in an enclosure and make it a portable hard drive (< $10 for a cheap usb2 hard drive enclosure). Plug it in to any of the 5 computers that does read from usb external hard drive, and back up the data that way. Wouldn't take 4 hours.

First, a recommendation: Turn off the Folder Option that hides file extensions. I find it only makes it more confusing and easier to misidentify files and their file type. CtlPnl->Folder Options->View. Scroll down and uncheck the box to hide file extensions for well known file types.

Next, I'm curious... do these two files currently exist? C:\Windows\inf\usbstor.inf and C:\Windows\inf\usbstor.pnf

Next, run the DriveCleanup Tool.

Next, we'll try to recover files from your Windows FileRepository.
> Look in C:\Windows\System32\DriverStore\FileRepository
> Find and open the most recent folder (there may be more then one) whose name starts usbstor_inf
> Copy files usbstor.inf and usbstor.pnf to the Windows\inf directory
> Copy usbstor.sys to Windows\system32\drivers directory
> Delete the INFCACHE.1 file as you did before
> Reboot your machine

Try connecting the drive again

Added instruction to run DriveCleanup Tool

These were the two crucial files that were missing on some other user's PC with the identical problem.

I made mention of this up in post #4 above, in which I provided a link to the web article on this identical problem for another user of failing to properly recognize the same WD drive exactly as OP in this current thread:

"The user still had problems, and discovered that USBSTOR.INF and USBSTOR.PNF were somehow missing, as described by this other article. "
