Currently, my SanDisk Cruzer Blade 4GB have become a 64MB Firebird RAW flash drive (thumb drive). I don't know why it become like this but when I plug it into a PC, it suddenly transform itself to become a 64MB flash drive. (From 4 GB to 64 MB, that is a huge change!)

I read the following articles:

and notice that their solutions do not work at all.

Some of their solution is as follows:

  • Using the HP USB Disk Storage Format Tool, which did not work for me as it could not format.

  • Using the h2testw to see if it is genuine, which did not work for me because it is a RAW partition.

  • Return to the vendor, which I doubt since the product only have 1 year warranty and it has expired.

I also notice that the flash drive is very fragile as after a few use, the flash drive have become something like the following: (The upper cover of the USB connector was broken or torn)

So, wondering if someone have any good solution to fix it back so that at least I can retrieve my data on the fragile thumb drive.

What operating system? Have you tried reformatting it by right-clicking on the drive and selecting format? (if you're using windows) –  Thraka Nov 19 '12 at 6:58
    
I tried on Win 98, Win XP, Win 7, Win 2008 and also tried reformatting it by right-clicking on the drive and selecting format but it just don't format. –  Jack Nov 19 '12 at 7:14
    
Try running GParted, delete all partitions, create a new partition, format and if successful see whether this utility can test the drive. (Use data recovery utilities though if you want to recover existing data, and don't repartition/format in that case!) –  Karan Nov 20 '12 at 14:51
    
@Karan, the problem is that I can't even delete any partitions, neither can I create or format it. –  Jack Jan 17 '13 at 4:40
    
Does USB Flash Drive Tester have anything useful to say about the drive? –  Karan Jan 17 '13 at 4:53
