Firebird 16gb flash drive now shows only 64mb.

Try this, my last ditch attempt - You will be formatting the drive though. My personal solution and steps to try is :

  1. Press start, type “CMD”, and open CMD with administrative privelledge

  2. When the command prompt opens, type “Diskpart”, then press enter

  3. A list of drives detected by your computer appears. Type “Select Disk x”, where x refers to the USB Drive (should be 14g size). Press enter. 
    WARNING: SELECTING THE WRONG DRIVE WILL CAUSE LOST OF DATA IN THE WRONG DRIVE. PROCEED WITH CAUTION

  4. command prompt will inform that the disk x is selected. Type “clean” and press enter. Drive will be ERASED.

  5. Once complete sucessfully, CLOSE the command prompt window. 

If this works, your chances of getting the drive back is slightly higher than 0 (maybe 5%? I dunno, haha)

  1. Press Win+R on your keyboard, and type " diskmgmt.msc", press enter.

**7) **You will see a 16GB unallocated space for the thumbdrive disk, if the previous steps were succesful

  1. Right click on the unallocated space, select NEW SIMPLE VOLUME

  2. Enter the MAXIMUM size of allocated space allowed, then NEXT. Assign a drive letter etc, may appear. If so select a drive letter than isn’t used by another drive. Then a summary of works appears, Select next, and let disk management format the disk.

  3. If succesful, the unallocated space becomes blue, meaning allocated.

  4. Your drive shows up in windows as blank with 14-16GB. WAIT! DO NOT USE THE DRIVE YET.

If this works, your chance of getting the drive back is very good, and you have 1 shot at recovering the files! 

If there are errors reading the disk (e.g. CRC fail or cannot read etc, i’m sorry…i have no other solutions than an RMA to sandisk)

Recover files

  1. Cross fingers and say your prayers, hope your other methods you tried did not damage your files too much!

  2.  Download RECUVA zip file from this link to your desktop: https://www.piriform.com/recuva/builds

14) Extract the zip file, and run Recuva64 or Recuva.exe

  1. A recuva wizard appears. click cancel

  2. The main recuva window appears. Select the newly formatted usb drive in the drop down box, then click options.

  3. Under actions tab, check the tick boxes for “Enable Deep Scan” and “Scan for non-deleted files”. Press okay

18) Now, press scan in recuva. Let it do it’s work! May take 30 mins to 2 hours, depending on drive.

  1. All recoverable files will be listed. Select ALL by ticking the checkbox at the beggining of the list, and press the ‘recover’ button.

  2. IMPORTANT: WHen the prompt asks where to save recovered files, save them in any drive EXCEPT the usb drive! Otherwise you cannot recover the files! Your desktop –> Create new folder’ would be the best choice

  3. press okay, then let recuva recover all the files.

  4. Once done, you can close recuva and examine the recovered files. I hope you can recover most of your files. Good luck! 

  5. Send the drive for RMA. Maybe the drive has reached end of life and is becoming corrupted. 

I wish you best of luck in getting the files back and getting the RMA. I wasn’t so lucky when this happened to my Sandisk 32GB Ultra Micro SD Card (I lost all my files, no backup!). That incident alone made me lose confidence in sandisk micro-sd cards imo, and i had no receipt to change them, so they are stuck with me. Now using another brand for my micro-sd cards

Cheers and best of luck!
