Флешка JetFlash 210

Купил флешку. Потом оказалось, что она со сканером отпечатков пальцев. Вот, что говорит Linux при подключении флешки:

Т.о. 2 раздела - один vfat, другой - isofs:

/dev/scd1 on /media/JetFlash 210 type iso9660 (ro,nosuid,nodev,uid=1000,utf8)
/dev/sdb1 on /media/USB DISK type vfat (rw,nosuid,nodev,shortname=mixed,uid=1000,utf8,umask=077,usefree)

На iso лежит вендовый firmware - всякие dll, exe.

Сюрприз заключается в том, что на разделе vfat доступно 10Мб, а не 1Гб, как написано на коробке.

Я в замешательстве.
