I am trying to format a micro SD card from Ubuntu to use it for flashing ROMs to my tablet. When I get an adapter ( I tried lots ) from micro SD to SD and plug it into my SD slot the card shows up, but when I click on it in Nautilus I get the message:
Unable to access "32 GB Volume"
An operation is already pending
Also it disappears and appears back again about every 5 sec.
I'd really like to get it working, because it's a very fast card that I also need for my 360 camera and drone, because they also need very high write speeds. In Gparted it shows up as /dev/mmcblk0
which I obviously don't have that many devices I only have a Hard Disk and a MSATA SSD, so /dev/sda
and /dev/sdb
. When I try to format it in Gparted it says input/output error, and sometimes on the start of Gparted I see /dev/mmcblk0 is not a directory.
Thanks in advance.
/dev/mmcblk0
indicates that the card is identified not via USB but via an internal card reader. Did you insert it into an internal card reader and then unplug it without unmounting and after that connect it via an[other] adapter again? It is also possible that the card has theexFAT
file system, which is a proprietary file system own by Microsoft. In this case you can install special tools to read/write files. The card could also be failing, but there are many things to check or fix, that might bring it 'back to life'. Anyway, please specify details about the card: brand name, model, size.dmesg
and about the card: brand name, model, size, maybe more details, and it will be easier to help you.
