USB flash drive cannot be read only on a specific computer

usb-flash-drive

I have a SanDisk Cruzer 32gb flash drive that cannot be read only on a specific computer due to some unknown reason. Do note that all my other flash drives are working fine on this computer. Here's my situation…

Background Info

I recently bought a HP laptop. Before wiping the laptop's hard disk, I used HP recovery media creator to store the HP recovery image in my flash drive. After I was done with wiping my laptop's hard disk and making sure my clean installation of the operating system works, I wiped my flash drive with the standard Windows formatting utility. I don't like the OEM's recovery stuffs because of all the bloatware, but I backed it up to my flash drive just in case my clean installation fails.

The Problem

Now, this flash drive cannot be read on my main desktop (running Windows 8) anymore. However, the same flash drive can be read on my other two computers (also running Windows 8) perfectly fine.

Observations:

  • The flash drive cannot be accessed in Windows Explorer or any Explorer alternatives.
  • Received "Windows can't access this disk" error messages when trying to check the disk's filesystem.
  • The flash drive's size cannot be viewed in My Computer.

Ironically, according to the Device Manager, the USB flash drive is detected and working fine.

Things I've Tried

  • Uninstalling the USB mass storage driver and rebooting.
  • Uninstalling all USB drivers and rebooting.
  • Wiping and reformatting my flash drive on the computers that it can work on using MiniTool Partition Wizard.
  • Using BootIce to rewrite the MBR of the flash drive.
  • Copying the MBR of my other flash drives to the problem flash drive using BootIce.
  • I've also tried formatting in FAT16, FAT32 and NTFS.

All of the above methods have failed. Does anyone know what's the problem, or have encountered such errors before? Please enlighten me. Your help is much appreciated.

Thank you. =)

Best Answer

I had a similar issue before and this is what i did to resolve.

Open Device Manager and then plug in the drive.

  • Device Manager was blinking when the drive was plugged in, so something was recognizing it. However, no additional disk device was appearing.

  • Looking in the "Universal Serial Bus Controllers" section in Device Manager, there was a "Mass Storage" driver loaded. Other USB drives when plugged in would load a "USB Mass Storage Device" driver for a moment before that disappearing and the additional disk device then appearing.

  • I right clicked and uninstalled the apparently erroneously loaded/associated/cached "Mass Storage" driver. When the drive was reconnected the proper "USB Mass Storage Device" driver then loaded and it started working again.

I think the cause of it was removing the device while Windows was still loading the drivers for it. Sometimes Windows takes a while to fully recognize a device (USB devices can have "subdevices" which require a chain of drivers to be scanned/loaded) and if this process is interrupted it may remember the wrong driver for the device.
