There are two separate issues in thumb drive formatting.  One is the
filesystem type, and FAT32 is pretty common.

The other one is whether there is an MBR with a DOS partition, or the
more recent GPT.   If you were to take a flashdrive, put it in a Mac,
and format it as "one partition, FAT32", I think you will end up with
EFI.

My impression is that the Elecraft firmware requires not only FAT32 but
also MBR partitioning instead of GPT partitioning.  But I am only 80%
sure.

Re: [Elecraft] PX3 & thumb drive... SD card works

[Stephen Shearer]

PX3 doesn't "seem" to have a size issue...  aka my 128M vs 16G thumb drive.
As I said I would, I tried an SD card (Class 10 and 16G) with a USB 
interface.
The SD card worked ("M" showed on the screen of the PX3) for both the 
USB2.0 and the USB3.0 interface device.
SO, something is different between the SD card with an USB interface and 
the USB "drive" even if both are FAT32 formatted...

See if "we" get any input from Elecraft as I also CC'd a PX3 developer.

I had an issue where a thumb drive was needed to upgrade firmware in 
an Agilent digital scope but we didn't have appropriate thumb drives, 
so I took a 1 TB USB spinning hard drive and partitioned with the 
first partition being a small fat32 partition with the firmware cab 
file and it worked great.


If you try this and it works, please let us know.

One thing you might try is use Windows disk management in the 
administrative tools section of control to partition the large thumb 
drive with a first fat32 partition that is 2 or 4 GB - if your whole 
drive is fat32 you should just be able to shrink it down to a size that 
may work.  If it isn't fat32, delete the partition and create a smaller 
partition that is.  Then you can create a 2nd or more partitions after 
that one for NTFS or whatever.

Re: [Elecraft] PX3 & thumb drive...

[Stephen Shearer]

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.


73, steve WB3LGC


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. *

Re: [Elecraft] PX3 & thumb drive...

[Stephen Shearer]

It isn't a problem of file name..  The PX3 won't see the new thumb 
drives.  It reads the OLD drive just fine.  I don't have a problem with 
the name as I edit with the contest name in the filename and then 
copy/edit to the one the PX3 reads.  works great, except 16G drives - no 
go.  73 steve

[Elecraft] PX3 & thumb drive...

[Stephen Shearer]

I have read, tried, and still can't use a "modern" thumb drive (USB)... 
with my PX3 for data transfer.


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"...
