This is the answer…




    16 G bit = 2 G Bytes ≠ 4 GB

What now?




How to fix?

              28 / 65

First, we need to recalibrate fake flash drives

This is UdTools v.1.0.4.6
         for chips: AMECO 8208, 6208A, 6208E (MW6208, MW8208)

UdTools automatically detects flash drives



Just plug-in USB flash drives (1,2,3… ) and click here




                 ...
ook at this Tab




                    Low quality,
                    high speed
                    (it takes about a ...
Here you can
set ANY capacity…
4GB, 8GB,… 32GB,…

Please, do not do it!

Yes, recalibrating takes a lot of
time .
Also, 15% of flash drives are
completely dead (see next slides).


              ...
39 / 65
40 / 65

Bad soldering. . .



                     42 / 65
A box of crap — 150 dead flash drives. . .




                                             43 / 65
Next problem: How to
glue/stick/bond ”live” flash
drives?




                               44 / 65
45 / 65
We try to glue them again




                            46 / 65
By cyanoacrylate. . .




But it takes so much time. . .


                                 47 / 65
So we use ”batch processing”




                               48 / 65
put both pieces together. . .




                                49 / 65
stack it. . .




                50 / 65
take some weights. . .




                         51 / 65
52 / 65
press down the stack of flash drives. . .




                                            53 / 65
take hairdryer. . .




                      54 / 65
and fan flash drives with hot air. . .




                                         55 / 65
especially edges. . .




                        56 / 65
regularly. . .




                 57 / 65
press down the weights with your hands. . .




                                              58 / 65
So flash drives are bonded with melted plastic edges




                                                       59 / 65

61 / 65

but still ugly because of melted edges,

So we presented all these recovered flash drives. . .

  33. ook at this Tab Low quality, high speed (it takes about a minute)… Best quality, low speed (about 30 minutes)… Use "Special Scan" only for very bad flash drives with a lot of bad blocks this mode reduces capacity of a flash drive 33 / 65
