I had a similar problem: 

I used two 64 Gb cards working flawlessly for a year or so. 

Then all of a sudden the same problem (like you had) with both cards. 

 

I tried everything, and I mean everything(!) - all formats, all my files which worked fine previously. All firmwares, Whatever you can imagine in your wildest dream. 

I guess I spent 20 hours or so of my time on this frustrating process. 

Miraculously I managed to force to work only one of these cards - now in fat32 format only. 

It does work after the cold start without forced rescan again. 

 

Tomorrow I am buying one more card of different brand - to try my luck again and probably to spend 20 hours of my time on it again. 

 

 

And I am buying Cowon PLENUE 1 128Gb, they say it has the stable firmware with very few glitches and bugs. 

And having 128Gb on board I hopefully won't have to spend my time on cards but just listen to music...

Thanks for sharing your experience! 

I bought a new 64 Gb card (but different brand this time). It does work with no issues. And it is filled to the brim with my flacs. 

So the problem seems to have been solved. 

I just don't know what to do with the previous cards...

I had the same problem, but it was prior to the 2.004 firmware.  First, I would take out my 128gb class 10 card to add more music to it.  After doing this about 6-8 times, it would eventually show up as empty folders the next time I turned it on after a prior shutdown.  I grew tired of rescanning the card (which seemingly takes forever) every friggin time just to listen to the DAP.  I stumbled upon the solution, for me at least, which was to go to the setting menu and "reset settings" at the bottom of that list.  After that, the DAP worked just fine.  I haven't had this problem yet since I've updated to 2.004, but that's probably only because I haven't been updating my card with more music as often as I was before.  I hope this solution will still work!!

Can I charge it with a Powrr Bank or is the Hifiman plug really the only one?

Doesn't work with the USB charging, so you can forget the power bank. You can only charge it with a brick-sized hifiman charger.

Ok but certain power banks have a DC output 9V and 12V, other may have other voltages, question is, will the common plug they use fit into HM-901 or is it very special?

You get one proprietary USB cable (S/P DIF input/RCA Line out cable) which doesn't support the charging function, and a separate charger where the cable, (hifiman's proprietary something like Apple), is "glued" to the charger unit.

I've tried everything and it didn't work, except with the original hifiman charger.

Got it, thank you very much!

There is one point more to charging the HM901 battery:

It is actually two batteries, not one, and they are not equally big in capacity.

In other words, it's going to take more than a simple charger to do the job.

Hello!

I've just received brand new hm-901 and the thing is just freezing completely during startup logo, reseting won't help either.. Has anyone encounter something like this? I'm deeply in pain atm...

Hopefully it is working, if you simply start the player by pushing the power button for 2-3 seconds (don't touch any other button while doing this). Start it without any SD card and wait for about two minutes. If still no good, then:

Try reinstalling firmware. You MUST use a SDHC card (max 32GB), no SDXC cards. The update.zip file also must be at the root of the card (in other words, not in a folder).
