Find Your USB-Flash in this table:
http://forum.flashboot.ru/index.php?...h&op=printpage

table contained:
|Manufacturer|Model|Memory|VID|PID|MCU|MemoryCHIP|SOFT|

You need to know what the MCU inside Your USB-Flash.
Possible You need to open case of USB-Flash & looking MCU's marking.

When You know what the MCU inside Your USB-Flash, looking in table last row "SOFT", this is manufacture's soft to reflash firmware inside MCU & low-level formatting memory-chip!

Get this soft from here:
http://forum.flashboot.ru/index.php?...es&op=cat&id=2
here names of manufacturer's of MCU in alphabetical sorting:
Phison
Alcor
iCreate
OTI
SMI (Silicon Motion)
USBest
Skymedi
Prolific
AMECO (MXTronics)
Chipsbank
Netac
SSS (Solid State System)

Enter & get manufacturer's tool, then make with this tool full reflashing of firmware of MCU & make low-level formatting of memory-chip.

After this Your USB-flash must be as new.
But need to formating by standart way.
