hello guys
my hotspot crashing problem im using 6.37.5 ROS and my database log point to external microsd card (brandnew samsung) with fat32 formatted. is this ROS bugs version problem? see attached
Notice red logs…user-manager is not able to write logs to the SD.
Check the SD is write enabled.
I’d format the SD inside routerOS.
I wouldn’t use FAT32. Apart from being a crappy FS, this SD is going to be used exclusively by the router, so what’s the point?
Additionally, as per Dude server install Wiki entry:
If added disk by default is formatted with fat32 file-system then we recommend to re-format it to ext3 file-system.

/file print detail
Afterwards if you still experience problems while using ext3 will aid in helping you.

IO errors generally means bad news.
Try a different SD card. Brand new, is not a guarantee that it’s not broken. It looks to me, like the SD card is faulty, or there’s perhaps some incompatibility between the MT and the SD card.
This thing is really complicated.
ok i will buy brand new again 
the one i buy is the original from samsung.
