What are estimated times taken for resizing an SD card? I have a 32G card and it seems to be taking extra-long (over two hours waiting now)

  • While two hours seems a little long. Let it run. If I were you I would let it run overnight if need be before pulling the plug. Removing the power while it is resizing the disk will likely require you to restart the process from the beginning. Commented Aug 29, 2012 at 1:55
  • Mine took just a few seconds. It was a Patriot LX Commented Aug 29, 2012 at 3:51
  • @gnibbler: How big was your card? Commented Aug 29, 2012 at 6:12
  • @ohblahitsme, 32GB. I also have an 8GB which was also quick. Commented Aug 29, 2012 at 6:18

I resized my 16GB class 10 SanDisk card, and it only took a few minutes. I resized the root partition to fill the card with the gparted GUI on my laptop, rather than my RPi (like PhonicUK, I think).


Depends on the size of the card, how fast it is and how good the reader is.

I did a resize on a 16GB Class 6 card and that took about 35 minutes all in all. I did it using gparted on a laptop instead of on the device itself (which I would imagine would be very slow)


I resized a 32GB Class 10 card from raspi-config, and it took about five minutes.


My experience: About 10 minutes, using the raspi-config on the Raspberry Pi itself with at 16GB Class 10 card.
