mmc/sd card issues (error -110)

[pepedog]

All seems hit and miss
I got a Transcend 64Gb SDXC class 10 that works fine.
I manually configure partitions and copy on files though
Do not take device names literally, dosfstools e2fsprogs and parted required, best remove udev-automount, and my card is in an adapter.

HI all, sorry to bump an old post but I ran into the same issue with the Kingston SD cards. Would recommend checking if the card is supported before buying it, as a lot of otherwise good cards are unable to boot on the pi

I picked up a pair of DaneElec 16GB class 10's and they work a charm

I have similar issues with Lexer 16GB SDHC class 4 card. It failed more than three times.
First issue : The card could not be formatted in any PC . Solution : format the card first in any camera/video device
subsequent issues : while on writing/reading to the card it miserable failed and some times the partition became read only.

--Currently using 32 GB sandisk microsdcard version 4 (failed once and now ok- RPi running two days on it without any issue). By trail and error with over_voltage=2 with default frequency things seems to be fine (for any one has keyboard issues use dw_otg.speed=1 in cmdline.txt as mentioned in their wiki)
