PX3 & thumb drive...

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"...

Is SanDisk the problem? Why? Help, is there something I am not doing?

73, steve WB3LGC

Re: PX3 & thumb drive...

There was a bug in the last firmware update that has not been fixed. The
file name that the PX3 saves the data to is different than the file name
that it tries to read the data back in from. Until the firmware is
corrected, you need to manually edit the saved file name to have it match
the expected read from name. It has been a while since I did this, but I
will pull my thumb drive and post the two different names shortly.

Re: PX3 & thumb drive...

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

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.

73,
Bill

Re: PX3 & thumb drive...

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: PX3 & thumb drive...

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.

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.

Re: PX3 & thumb drive... SD card works

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.

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.
