My Extreme USB 3.0 device (SDCZ80-064G) is not recognized properly suddenly today in both of my laptops with Windows 7 x64 installed. Both Vaio & Lenovo have USB 2.0 and USB 3.0 ports, which Vaio expanded USB 3.0 ports by adding ExpressCard Adapter. My Extreme USB flash drive was formatted in NTFS file system and worked smoothly until yesterday. I have tried to plug the flash drive into USB 2.0 & 3.0 ports on my laptops many times, the blue LED does not illuminate instantly anymore during Windows detecting the drive as usual.
Both laptops do detect the flash drive, but it is recognized as “USB Device” instead of “SanDisk Extreme USB Device” in Device Manager. Its show the device as “Fujitsu MB86C31” instead of “SanDisk USB Flash Drive” at “Devices and Printers” in Control Panel. Also, both OS mounts the drive as “Removable Disk F:” in Disk Management showing no media, and appears the same as in “My Computer” When I double click onto the disk under Windows Explorer, a notification window pops up, which stated "Please insert a disk into Removable Disk F:”.
I could not format the Extreme flash drive under Windows Explorer, Disk Management, Diskpart in cmd prompt, and 3rd party low level format software. I have changed the drive letters couple times to avoid conflict. Also, I have manually located the driver within the OS, cleared hidden devices and make changes to the Registry following the instructions on SanDisk supported website - http://kb.sandisk.com/app/answers/detail/a_id/139/kw/flash%20drive . However, all of the works above do not fix the problem!!! Please refer to the pics links for details.
I know that my flash drive is mostly unfixable, however, there are some important data that I need to recover from this drive. Therefore, I would really appreciated if anyone can provide me any solution to fix this problem.
