Clone multiple SD cards

Mon Oct 20, 2014 12:39 pm

Could anyone point me to hardware which will automate the process of writing an image to multiple microSD cards?

I want to avoid intialising cards 'by hand' with my laptop. I would like to achieve the same effect, but with less time and energy.

If we could initialise up to 20 cards at once, just by pushing a button or typing a command, that would be ideal.

I read somewhere that such machines start at about 500 pounds. But, I have not been able to actually locate any for sale. Partly, this may be because I don't know what they're actually CALLED. (SD card Printers? Writers? Cloners? I'm not sure.)

Thank you in advance,

As @Dougie has pointed out, they are usually stupidly expensive.
There is nothing stopping you buying a few USB SD card read/writers to speed things up a little.

Buy several USB hubs and SDHC compatible SD card readers. Install Linux on your machine. Install dclfdd. Write to several cards at once (the more hubs /readers you use the slower it might get ).

This can be helpful, if you're on Windows https://github.com/RomanBelkov/DiskImager/releases.

This is a utility I found on GitHub and added ability to write on multiple SD. I've managed to write 1.5 GB firmware (pure .img) to 4 SD cards inserted in one hub in 5 minutes

Ghans put me on to dcfldd about a year ago. As he says, a couple of multiport USB hubs and some cheap sd to USB converters works really well.
I regularly use it to clone class sets in batches of 8 at a time.
