I haven't had any problems with my Sandisk Extreme 128GB SDXC Card.  I left it with exFAT format and have copied over 100GB in one session without problems.

 

I'd recommend getting a decent UHS-I compliant USB3.0 SDXC card reader, though.  Seems some UHS-I cards can be picky about different card readers.

You got the HM-901 to read exFAT!? I left my 128GB at home cos I copied my tracks over to it exFAT format and this morning it wouldn't read it. So I reformatted it back to FAT32 and left my files copy over again whilst I'm at work.

Agree with Edwood you'd better use proper SDXC compliant card readers.  I'm using the Sandisk USB 3.0 cardreader with a Kingston 128GB SDXC card in exFAT format without any issue or long loading time.  In fact the reason for exFAT for SDXC is because the older FAT32 format is too inefficient and slow for larger capacity card so unless the card reader itself in the unit does not support FAT32, you should use exFAT.

 

I have also use the Sandisk 64GB microSDXC with adapter with the 901 and also don't have any problem.  You card reader seems to be the prime suspect causing issues.....

That was the reason why I left my SD card in exFAT last night. But my iMac has an SD Card slot of which I use regularly. I need a dedicated SD card reader rather than the built-in Mac one ;-(??

I find the iMac one is slow but given mine is circa 2012 not the latest so YMMV.  Also, copying files in MacOS create a bunch of .xxxxxx files (hidden) that are useless.  It also create the spotlight index and .trash etc which is extremely annoying.  As much as I love my iMac and MBA, files operation is just not a strong suit with MacOS in my experience be it copying to removable media or my QNAP NAS.

 

Read from chinese forum the 901 browse faster when there's less "junk" files.  I only keep the actual tracks and a .jpg file for each album.

From the command line:

  • mdutil -i off /Volumes/USB Volume
  • cd /Volumes/USB Volume
  • rm -rf .{,_.}{fseventsd,Spotlight-V*,Trashes}
  • mkdir .fseventsd
  • touch .fseventsd/no_log .metadata_never_index .Trashes
  • cd -

Where USB Volume is the actual mount point your stick gets attached too.

I did this for my USB external drive, works like a champ.

Great info, I'll stick with Sandisk then.

Wow. U're more thorough than me. I just whack out any .* files in the SD card.

find /Volumes/[SD Card] -name ".*" -exec rm -rf {} \;

Would running a system wide daemon have any performance hits?  I do plenty of .raw and some video processing and is wary of anything that can impact I/O speed.....

Just got home. Ejected my SanDisk 128GB & popped it into the HM-901 and card error :-(. Grrr!!

Maybe this is stupid but running the disk error identification and repair on dos would not help ? chkdsk G: /f/r

I don't run a lot of I/O or computational intensive stuff but my Macbook has been fine since I installed that.

That sucks... probably some bad sector or dirty bit on the SD card already?  Try to fix that before copying again.  Best luck man!

Different cards. At work it was the SanDisk MicroSDXC with the adapter. At home, it was my Transcend 128GB. Anyway, after inserting/removing a couple of times it's reading now. So no more touching. No more ejecting SD Cards :p.

 

Interestingly though every low capacity card I put in (and I mean really low like 2GB/4GB) read on first go.
