USB memory sticks can be very different.
They differ on Hw and Sw aspects, even inside a given brand.
In particular, USB memory sticks targeting audio recording are often
formatted in very specific ways and the format is often very different
from a standard FAT.
For all these reasons, we advise users to use memory sticks provided
by Viavi.
In any case, USB memory sticks which are recognized by the 4000
Platform (a sound is generated when plugged on the 4000 Platform)
but which cannot be read or written,
should be formatted on the
4000 Platform with the Usbflash Format utility, in Expert tools >
Media utilities .
If a problem occurs with the USB stick you are using, contact your
Local Technical Assistance Center.
