content: There appears to be an issue with USB flash drive compatibility, especially for drives that aren't oldandvery low storage capacity (general generic compatibility aside).I first posted my issue here:https://www.eevblog.com/forum/testgear/siglent-sds2000x-hd-12bit-(published-for-chinese-domestic-market-only)/msg5845999/#msg5845999After further testing, and considering Joe's issue (below), it seems more thought needs to be put into this by Siglent. When I mentioned the issue to a Siglent rep, his repsonse was "I would use a smallish USB drive if possible. It should be FAT 32 formatted." I expected and understand that response. However, it's 2025. 32GBisa smallish USB drive. Availability of drives that small or smaller is only going to get worse. USB drive support needs to be improved.@joeqsmith had some USB compatibility issues as well. That thread started here:https://www.eevblog.com/forum/testgear/siglent-sds7000a-dsos-coming/msg5842321/#msg5842321Joe's test results and summary here:https://www.eevblog.com/forum/testgear/siglent-sds7000a-dsos-coming/msg5844027/#msg5844027Rudi also noted USB drive compatibility issues with the SDG1000X Plus:https://www.eevblog.com/forum/testgear/upgraded-sdg1000x-plus-awgs-coming/msg5822549/#msg5822549---These two exFAT drives failed to work in general with my scope:SanDisk 256GB Ultra Luxe SDCZ74-256G-G46SanDisk Ultra 128GB SDCZ43-128G-GAM46However, formatting to FAT32 with 512 cluster size made the SanDisk Ultra 128GB SDCZ43-128G-GAM46 work, without crashing with popups open. The 256GB drive still didn't work after trying different formats.This drive almost always works with all my test gear:SanDisk 32GB Ultra Fit SDCZ430-032G-G46TThe only exception is the bug I mentioned in the SDS2000X HD thread. Here is a video showing the bug tied to the SanDisk drive, and comparing it to a Kingston 32GB drive. Both drives are formatted as 32GB FAT32 32k clusters using the SDCard Formatter utility:(Apologies for the camera wobble.)I tried formatting the SanDisk drive using Windows 11 and MacOS in FAT32 and exFAT, using clusters from 4k to 32k, and nothing improved it. Some combinations made the drive undetectable.I have not had any issues with the Ultra Fit 32GB with any TE brand, including Siglent, except for this one issue.This drive still works when the Ultra Fit 32GB doesn't:Kingston 32GB DataTraveler Mini Rex DTMRX/32GBKingston, SanDisk, Crucial, and PNY are major brands and compatibility shouldn't be a concern.Thanks,JoshMy scope: SDS2504X HD (black)Firmware: 1.2.2.9OS: 2.5I'll try and keep this updated here with a list ofdrives that work:FAT32 formatted:SanDisk 64GB Extreme Go SDCZ810-064G-G46Kingston 32GB DataTraveler Mini Rex DTMRX/32GBKingston 64GB DataTraveler Micro DTMC3G2/64GBKingston 128GB DataTraveler Exodia M DTXM/128GBVerbatim 32GB Store 'n' Stay Nano 98710Verbatim 64GB Metal Executive 99106SanDisk Ultra 128GB SDCZ43-128G-GAM46SanDisk 32GB Extreme SDCZ80-032GSanDisk 64GB Ultra Luxe SDCZ74-064GexFAT formatted:SanDisk 64GB Extreme Go SDCZ810-064G-G46

content: Compatibility with flash drives 8GB and smaller is more common. However, I won't spend money on anything that small. I have 32GB and larger drives going back at least 10 years. 32GB is small my modern standards, and many lines don't go below 64GB anymore.I don't know what's missing or messed up in the firmware that doesn't work more universally, at least with major brands. 🤷

content: Common problem with a lot of test equipment that uses USB drives. You need to stick with 32 GB or smaller, formatted with FAT32, never NTFS. All the old Tek scopes at work have the same issue. I don't know why new equipment should suffer from this limitation, but I had to search through my pile of flash drives to find a few that were suitable and dedicate them to the purpose. I buy neck lanyards so I can loop them through the equipment handles, lest they develop legs and walk away.

I have a few other drives coming I'm going to test.I hope Siglent (and others?) will choose to improve this. If not, at least we can get a list of the best modern flash drive options that work without issue.

content: My first computer had a cassette tape drive; floppy disks were too expensive (for me).To the point.As I have already written elsewhere, which was attributed to me as an OT starter() , I have no problems with any stick I have at home.However, the largest of these is a maximum of 64GB and almost all of them are from SanDisk.Whether siglent now has to ensure that every stick you have at home is compatible, I can't say.However, it didn't seem to be a major problem so far, otherwise some kind of compatibility list would have been published for sure.At least the touchscreen scopes are equipped with Linux and an SoC.For the latter, you would have to find out what disk size is generally supported.

content: The main issue is probably that Siglent forgot to install support for exFat (which involves more than just enabling an option in the kernel). Most USB flash drives are formatted using exFat nowadays so if you are developing an embedded Linux system that needs to be able to deal with USB flash, you need to add exFat support.

I did eventually get a floppy drive for the VIC-20.But I know you don't like to wander.Quote from: Martin72 on March 16, 2025, 09:27:03 pmAs I previously wrote, I had 2 out of 4 different brand/model USB FLASH drives fail when used with the Siglent 3000 when they were formatted using NTFS. You keep going on about testing sticks. My point is that Siglent's manual calls for FAT32 in the troubleshooting section of their manual. They are certainly aware of the compatibility problems with formats outside of FAT32. Yet they decided to make their manual ambiguous by only recommending FAT32 in the primary section of the manual. It seems like an easy fix and doesn't require a lot of testing. They seem to have already done that and are aware of it.I was just looking for some English help rather than Chinese and a unambiguous user's manual. If the fan boys feel it is good enough, so be it.

content: Quote from: squadchannel on March 17, 2025, 01:56:25 amNo, I've tried a range of allocation sizes, and it made no difference. The only time the Ultra Fit didn't work outside the bug is when I switched to exFAT. No matter what I've tried otherwise, the drive fails only with an info/options window on the screen.It could be a resource issue? If the drivers are a little wonky and taking up too much resources, the extras on screen could make it crash, but that's really not great if that's the case. For any USB detection there's a brief pause of the measurement count, and obviously a complete halt when it crashes.

content: Verbatim 64GB Metal Executive 99106 also works without issues so far. OP updated.SDCard Formatter can't be used for drives over 32GB (as Rudi pointed out), make sure you use FAT32 if you format the drive. I hope Siglent eventually adds exFAT support.Also, formatting the SanDisk Ultra 128GB SDCZ43-128G-GAM46 to FAT32 on my Mac made it work. A good formatting utility in Windows would probably also work.Thanks,Josh

content: I also have problems with USB flash drives on my SDS1202X-E. It's very annoying. There's about a 50/50 chance that the entire scope will crash completely locked up (totally unresponsive - not even the power button) when inserting a USB flash drive.I wouldn't mind if it was consistent, but sometimes it works and sometimes it doesn't, even with the same USB drive. I haven't been able to pin down anything about what contributes to the problem. And when it does work, afterwards Windows always complains about "there's a problem with this drive", for which scanning for problems never finds anything to fix (presumably due to lack of 'eject' feature on the scope, although shutting the scope down with the USB drive still attached doesn't yield any different results).I've just totally given up trying to save screenshots to USB from the scope, and now I just use my phone to take photos of the screen, like some kind of neophyte. Sigh, should've shelled out the extra cash for the SDS1104X-E so I could use the web interface.(Why on earth did Siglent decide not to provide that feature on the 2-channel models?)I'm running the latest v1.3.27 scope firmware.The two drives I've previously attempted to use are:- Kingston DataTraveler Exodia M (DTXM/64GB), FAT32 formatted, 64KB cluster size- Kingston DataTraveler Exodia (DTX/32GB), don't recall what it was formatted asThe only drive I never had trouble with was an ancient Transcend 128MB drive, but that died.

I have the black model now, and exFAT on that drive did work, but it was the only drive so far that exFAT worked at all.Your info above says the drive is exFAT, try formatting FAT32 and itshouldwork. SDCard Formatter and Windows might not give any FAT32 option without using a 3rd party formatting utility.Thanks,Josh

content: I think I'm done with SanDisk. That SanDisk Luxe drive SDCZ74-256G-G46 is trash. I've used it less than 5 times since I bought it, and for some reason, it doesn't want to go into USB ports anymore without significant force. I tried emailing them at support@sandisk.com, from a link on their website in the warranty section, and I got a reply stating "Thank you for contacting Western Digital Corporation. You have reached an unmonitored mailbox." I also received another email from them showing a bunch of domain/email routing errors within their infrastructure. 🤣 Anyway, no thank you.
