Hi, I've read several reports of raspberry pi users which were able to perform batch discards on their SD cards by invoking the "fstrim" command, which in turn should be translated to an ERASE command (cmd23). I found out some patches where commited to linux-mmc which implement this functionality arround linux-2.6.36. However, all I get on my raspberry (as well as on my laptop) when running fstrim is: > root@raspberrypi:~# fstrim -v p2/ > fstrim: mountp2/: FITRIM ioctl failed: Operation not supported Has this functionality been disabled intentionally, or is it likely an issue with the SD card or the driver? In case this is hw specific, how can I find out the cause it is disabled?
