Lakka Raspberry PI3 file system corrupted

Hello there!

I have a problem installing Lakka on a raspberry PI3. I install it successfully on a 128gb SD-Card and was able to run lakka for a few hours. But for some reason, the system file appears to be corrupted. here is the message I receive on the screen Filesystem corruption has been detected! To prevent an automatic repair attempt continuing press any key…

I let the automatic repair work, but I have this message at the end: CP437 : Invalid argument fsck.fat 3.028 (2015-05-16) /dev/mmcblk0p1: 137 files, 37994/65501 clusters e2fsck 1.43.3 (04-Sep-2016) LAKKA_DISK: recovering journal Superblock needs_recovery flag is clear, but journal has data. Run journal anyway? yes

fsck.ext4: unable to set superblock flags on LAKKA_DISK

LAKKA_DISK: ************** WARNING: Filesystem still has errors **************

Forced fsck failed. Your system is broken beyon repair Please re-install Lakka

i tried both time, on 2 different SD-CARD same issue. because once this happens, SD-CARD is read-only, and I cannot find a way to remove this flag (try many tips, DISKPART, Partition magic, livecd and so on…) this is the 2nd time I loose an SD-Card :frowning: any help here would be gladly appreciate!

Thanks!

That usually only happens when you don’t shutdown properly and it’s powered off while writing something to disk. To avoid it, make sure you use the ‘shutdown’ option from the menu before pulling the plug.

You should definitely be able to at least re-format the disk unless something has physically broken on it.

Thanks for you reply, ok sounds clear now.

Unfortunately I think that both SD-CARD are dead :frowning: will try again to save at least one of them …

You should be able to format them on a PC.

I used to get corrupt SD cards with my Pi all the time. The reason was that my case had almost no ventilation so the Pi would overheat and corrupt the card.

Once you’re back up and running, try running the Pi with the case open or removed and see if you have the same issue. If that fixes it for you, modify your case or get a different one.

for my little experience, when sd cards became “read only” you can trash them. they have a little “spare area” that is used when memory blocks start to fail. (like ssd drives) when that area is full, the card became read only to allow user to at least backup data. this happen usually because a lot of writes on the card (you know all nand memories have a limited r/w operations). when my first 64gb ssd failed i was not so lucky, because it became “locked” i cannot even read it! in my lakka consolle i have the system on a 8gb card, and all roms, lists, temp folders and so on on a phisical hdd.
