With over 10 years experience with Siglent instruments I have made my own decision for my own use. I use only Kingston (2G, 4G) and 8G formatted to native FAT32 with 4k cluster sizes. And I keep these some sticks only for use with Siglent. These 2 and 4G have also led if there is some reason for watch activity)

Caution!!! Our luck with Kingston SD cards has been just the opposite, these are the only SD card brand that have failed (had 2) so we've removed all Kingston brand SD cards and destroyed them. I opened one before it was crushed, and found a unbranded micro SD card wire bonded to an SD case :o
These may have been counterfeit, don't know, but we don't buy memory products from unauthorized dealers off eBay, most are from B&H or local Best Buy which is likely where these Kingston cards came from.
Now, since the Kingston issue long ago all our memory products are from Sandisk, Transcend and the old Lexar (when they were owned by Micron which actually made the memory chips) and never had an issue with any of these memory sources. Our use was hard on the cards since many thousands of images were collected with our chip imaging work, this was repeated often so the cards got many read/write cycles with many images, tough use indeed!!
Don't want to bash Kingston, since these could have been fake and happened long ago, but we won't be using any Kingston memory product USB sticks or SD cards, others can decide for themselves.

I use free 4 GB USB sticks that my vendor sends me with every shipment filled with documentation. I have handful of those and they work perfectly.
Those that work best are USB 2 4GB or less. Format with FAT32 with 4k sectors and voila..
I agree with Nico, those Kingstons were probably counterfeits.

It is not a firmware bug. It is a upgrade procedure that cannot cope with absolutely every combination that can happen in the field.
Wrong thing was repeating same procedure expecting different outcome. I would have returned load and demanded it to be replaced with one with the current firmware, so they have the responsibility to do it right. I wouldn't do it twice in a row, same way.. And would demand explanation what happened.

I agree that digby definitely could have saved himself some headache/hassle by changing up his procedure.
Obviously I disagree that I think this is a serious bug, not just a quirk. Like the others in this thread have demonstrated, everyone seems to have different experience with different brands/types of flash. I totally understand how this happens on a development team because I've been there. You get something working, the lab has a big supply of a single variety of usb or sd card flash in the cabinet, and everyone falls into the habit of doing what works. Then the product ships and you realize not everybody has 8GB Sandisk Class 2 micro sd cards or whatever. I agree they can't support every possible combination but it needs to fail gracefully and safely.
And lastly I appreciate I may have inferred more offense than intended, sorry. It just felt like calling out a guy who was genuinely trying to warn others. If I owned this exact model I would have really appreciated the warning. I just bought another siglent product and I'll be keeping this in mind for sure.

This is a link to a video by Tomtektest who is a retired EE with a PhD. It describes a similar situation of upgrading FW on a Siglent AWG but from outside of the warranty period. Tom is a gentle soul and a very calm guy, not sure I would be quite so relaxed about it. If this turns out to be a brand defect that runs through the Siglent line, they have some work to do. I have an 1104X-E scope that may be outside warranty and I am concerned about updating the FW.
Just checked, I am still inside their 3 year warranty so I will get the ideal flash drive and get my scope updated.

Siglent fans, you are not doing any good to Siglent by bashing digby70, a buyer and a newcomer to EEVblog, with words like "bitching" and "Muppet". :(

Problem is that OP declared "Buyer Beware: Siglent Electronic Load ....This makes me doubt the quality of their products. I am now wondering if others are having problems with
Siglent test equipment as I was going to purchase a spectrum analyzer from them.".

We are in the middle of a very difficult & complex design task which includes a high voltage multi-output (7 independent outputs) power supply. To help with the power supply test and evaluation an electronic load was considered. After noting this thread title it does convey more than just a USB stick issue with the Siglent Load, and did raise an issue if the Siglent Load has more problems. After reading a few times, we went ahead and ordered the Siglent Load and accept the "Buyer Beware" risk ::)
Best,
