This has once happened circa 2017 and another time in early 2020. The computer does no longer detect the device or shows some error message that the device was not detected properly.

Both were similar USB+OTG flash drives from HAMA. Possible technical reason at post bottom.

I must say I already have terrible experiences with HAMA flash storage.

But this metaphorically puts the cherry on top of the cake.

It might have been shortly after insertion into a Grundig RRCD 3720 CD/USB/SD/MP3/WMA player. But if it is that device's fault, it never fried any other flash drives than these two.

I measured the voltage and it never went above 5.1 V, but something that might have caused it:

Upon powering the RRCD 3720 boombox on, the USB port is powered for around a third of a second, then powers off for a second, then powers on continuously.

That short ~0.3s power-on might have caused it, but I can not confirm it. A too short power-on span and quick power-on/power-off's should not break any sane flash drive.

If that was the cause, it proves even more how shit Hama flash storage is.

I dont have any experience with anything HAMA, but I have never had any luck with anything USB-OTG. There's either never enough power or the devices don't like each other. I think it's a mess. That said, the little switching surge may have damaged the OTG power pass-thru and knocked it out that way, especially if any of the parts were substandard.

I looked at the manual for the Grundig RRCD 3720: Were you using battery power or mains power? Things like those have really cheap internal power supplies and the surge may have also been dirty/noisy from the mains switch mode power supply. Best bet would be to let the boombox power up all the way and then attach the USB drive once the power is stable.

Mains power.

Indeed. This is a rare phenomenon. But it never happened to any other flash storage.

With all that said, all I can think of is to avoid HAMA brand altogether. Haha. Sorry your drive got nuked and thanks for your post, I now have another brand to stick on the 'do not trust' list.

I have even more bad experiences with HAMA MicroSD cards.

It's because I've been hacking your mainframe and stealing you Digi-Pixels.
