Yes, not class 10 takes longer... My thumb drives ARE formatted FAT32,
I checked. My OLD drive that works is a USB2.0 the new drive is a
USB3.0 speed disk. YES - I read the manual before I started this topic.
NOW, the class 10 comment in the manual... class 10 is marked on SD
cards. I am wondering IF the software developer is using an adapter
with an SD card rather than an "thumb drive".
*I have SD/adapter(s) and I will give it a try.* I just like having
fewer parts to loose when portable...
The problem isn't the speed of the thumb drive (aka class 10) but that
the USB 3.0 and larger USB 2.0 thumb drives DON'T get "seen" by the
PX3/P3 - no "M" on the screen.

What is a class 10 SD card? BTW, my USB3.0 "Flash Drive" is 150 MB/s
(read speed? up to...) and SD cards and USB thumb drives are not rated
the same - different association.
Answered by The WikiAnswers^® Community
Currently, the SD Association recognizes two Speed Classes: "Speed
Class" and "UHS Speed Class." Speed Class applies to SD, miniSD,
microSD, SDHC, miniSDHC, microSDHC, SDXC and microSDXC cards. These are
denoted by a class number within a C-shaped logo. The higher the class
number, the faster the card. In order to bear the SD Speed Class logo,
card manufacturers have to adhere to the minimum standards set out by
the SD Association.
Class 2 is the slowest SD card speed. Class 2 has a write speed of about
2 Mb/s and is suitable for standard definition video recording. Class 4
and Class 6 have write speeds of about 4 Mb/s and 6 Mb/s, respectively,
and can be used for HD video recording. These three classes of SD cards
are designed to operate under the normal bus interface.
*Class 10 SD cards have write speeds of 10 Mb/s and up and are designed
to operate under the high speed bus interface. *

VIC and all,
See page 29 of the manual...
"A USB Mass Storage Device (MSD), such as flash or thumb drive, can be used to save
and restore PX3 configuration data, save and restore macros and save the screen display.
The MSD must be formatted for FAT32 files. A faster (e.g. Class 10) MSD will capture a
screen display in 10 seconds while others may require several times longer".
Note the Class 10 reference. There are many that are not class 10. You can
format to FAT32 in your desktop or laptop.

I have an OLD thumb drive that works in my PX3 firmware 1.48...
I have a Targus.com M-Sys DiskOnKey 128M formatted as FAT32 that
works. (yes, 128 mega...) I have a San Disk Ultra Fit FAT32 16G (and other SanDisk) that
will not give me an "M"...
Is SanDisk the problem? Why? Help, is there something I am not doing?
