Sd-card failing form time to time

Help and Support Vero 2

ok, sounds comprehensible (even though i am wondering why raspberry-pi chose sd-card as removable storage now). anyway: thank you very much for explaining - i will try with usb-stick now.

Cost, size, and they can universally be booted from. They are cheap and small and that is why they are ubiquitous on SBC’s. There are SBC’s that have the ability to add eMMC storage like the Vero’s use internally but if you look at their cost you will find a 16gb module often costs more than a RPi does.

Just a long shot. Even though the SD card is formatted as ext4, what is the partition type (fdisk -l /dev/mmcblk0)?

SD cards were designed to store photographs and the like. A “high quality” card might be great for general storage but won’t necessarily be able to take sustained random I/O. There are “industrial grade” cards on the market, eg MicroSD Memory Cards - Swissbit, for the more demanding applications and I believe that new OSMC SD cards are more robust than average.

Using a journaled FS won’t help, either, since it will significantly increase the write operations.

partition-type is linux and partition-table is gpt.

**osmc@B2VERO** : **~** $ fdisk -l /dev/mmcblk0

**Disk /dev/mmcblk0: 29 GiB, 31104958464 bytes, 60751872 sectors**

Worth checking. I vaguely remembered a thread where there were (possible) problems because the partition type was NTFS with an ext4 filesystem.

I suspect you were simply pushing the card too hard. Your log was very “busy”.
