fabiorzfreitas Posted August 22, 2020 Share Posted August 22, 2020 I have a brand new CDP-S350 and it won't mount my flash drives. They're both SanDisk (bought from a trustable seller), one 64GB, one 8GB. For the 64GB, I tried both exFAT and FAT32 (formatted on Windows 10, quick mode), the 8GB one is FAT32. Whenever I follow the procedure described on the userguide, it'll stuck forever on "Mounting..." What can I do to fix that? (Right now, I'm formatting the 64GB with exFAT on normal format to try it out). Quote Link to comment Share on other sites More sharing options...
Brad Saucier Posted August 22, 2020 Share Posted August 22, 2020 FAT32 is the proper format. Have you confirmed the drives are working properly on other devices? Quote Link to comment Share on other sites More sharing options...

I checked on the userguide (https://support.casio.com/en/manual/008/CDPS350_usersguide_A_EN.pdf) and it mentions both formats on page EN-50 They both work on other devices, I formatted them both on my laptop (Windows 10) and they were all right.

Brad Saucier Posted August 22, 2020 Share Posted August 22, 2020 As yes, the newer Casio models added exFAT support. That is correct. Are they well known name brand drives? I've seen certain drives have issues working with a keyboard before, so it's not unusual. Quote Link to comment Share on other sites More sharing options...
fabiorzfreitas Posted August 22, 2020 Author Share Posted August 22, 2020 They're both SanDisk, which is probably the best flash drive manufacturer (as Kingston focuses on regular drives nowadays). I did a full (not quick) format on my 8GB with no success, so far I have: 8GB/Quick/exFAT = Fail 8GB/Full/exFAT = Fail 8GB/Quick/FAT32 = Fail 8GB/Full/FAT32 = Fail 64GB/Quick/exFAT = Fail 64GB/Full/exFAT = Fail 64GB/Quick/FAT32 = Fail 64GB/Full/FAT32 = another 2h30min before it's formatted Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted August 23, 2020 Share Posted August 23, 2020 So the computers read these, just not the keyboard? Very odd....I have several brands, Sandisk Cruze primarily-no problems with any Casios. 32GB, 16GB all work fine. Quote Link to comment Share on other sites More sharing options...

Perhaps I should add that I'm in Brazil, but every menu is English etc, I bought the keyboard from a trusted seller as well. And yes, they both work flawlessly with any computer!

Casiofun Posted August 23, 2020 Share Posted August 23, 2020 Try formatting the drive on the keyboard and see if that works. Quote Link to comment Share on other sites More sharing options...

I would say that your problem is not the formatting. You should be able to mount the drive, and then format it, but you are not even getting that far. You problem is the mount function. It will not mount any drive you connect, regardless of its current format. Try a factory reset (see right hand column of Page EN-9 of the manual). If that does not resolve the problem, then you most likely have a defective flash drive socket or a firmware issue, and should return the board to the seller as defective.

Brad Saucier Posted August 23, 2020 Share Posted August 23, 2020 I think if you have tried a number of drives and none of them have successfully mounted, perhaps the USB port on the keyboard is faulty. This would be the first time I've seen a Casio with a USB port come out of the box faulty. It's certainly a possibility however. Quote Link to comment Share on other sites More sharing options...

And I'm guessing that for updating firmware I would also need the mount function, right? Oh, boy, it'll be so sad to spend some days without the keyboard now that I'm getting decent at playing, haha Quote Link to comment Share on other sites More sharing options...
- T - Posted August 23, 2020 Share Posted August 23, 2020 If you received a board with damaged firmware, you do not want to keep it. Whatever damaged the firmware could have damaged other things - like the memory that holds the firmware program. If ALL features of a new board do not work flawlessly, out of the box, it should be returned as defective. Quote Link to comment Share on other sites More sharing options...
fabiorzfreitas Posted August 31, 2020 Author Share Posted August 31, 2020 Here's how it ended: I took it to an authorized technician and he found no problem whatsoever. Turns out that there's hard cap for size at 32GB and perhaps a soft limitation for anything over 4GB. Either that or my 8 GB is fake, I could only vouch for the 64GB one. Anyways, SanDisk doesn't even sell 4GB flash drives anymore, so I purchased some off-brand 4GB drive and it now works! Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted August 31, 2020 Share Posted August 31, 2020 Of course-most newer Casios have a 32GB limit for thumb drives, but no reason the 8GB shouldn't work-unless it is a counterfeit-there are many of these unfortunately-and even though the problem has been widespread, and for quite a few years (just Google counterfeit thumb drives, counterfeit SD cards) i have seen the same drives still being sold by various vendors-I know, i got stuck with several-but all were no-name brands but conterfeiters will even print fake labels to duplicate Sandisk, Kingston, etc. I have quite a few posts here about these, and software programs I needed to detect that these drives were in fact not what was claimed-not the right capacity-defective chips inside-and fraudulent firmware code to make the drive look bigger than it is. The counterfeiters get discarded memory chips-that are already marked defective-and put these in fancy-looking cases, alter the firmware, and these end up causing amazingly difficult problems-'ghost" files that seem like they're there, and they're not-faulty copy and paste functions-and can even crash a computer-and I'm sure a keyboard. One test program is simple labelled h2testW-I'd post it here but its an executable Windows file-you can find this and a few others-I like to run tests on drives all the time, now that I've been burned.

fabiorzfreitas Posted August 31, 2020 Author Share Posted August 31, 2020 Yes, I'm aware of that, there are specially a lot of counterfeit SanDisk drives. I can't vouch for it because I'm not the one who bought it, but I already have used this drive to successfully install Windows, which does require over 4GB of storage. Nevertheless, I'm running h2testW right now, I'll be posting the results once it's finished, thank you! Quote Link to comment Share on other sites More sharing options...
fabiorzfreitas Posted August 31, 2020 Author Share Posted August 31, 2020 Aaand it passed the test with no errors... Guess it will remain a mystery, but hey, at least my instrument is not defective :) 1 Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted August 31, 2020 Share Posted August 31, 2020 Right-never had a counterfeit Sandisk, very reliable. Quote Link to comment Share on other sites More sharing options...
