I don't know how to pass this argument via Grub. You can try remounting the partition with different options, example sudo mount -o remount,rw,relatime,data=writeback /dev/sda1 /Īnother option is to pass the argument via Grub.Įxecuting the above command gives this error message (in dmesg): EXT4-fs (sdb1): Cannot change data mode on remount How can I change the cache mode of an USB drive?.
I realize that this question is a duplicate of Does anyone know how to enable caching so that I don't suffer from occasional extremely high write (and maybe read) times? Probably enabling write-back caching will help. This frequently causes applications to become unresponsive for around 5 to 15 seconds (they usually turn grey during this time). It runs okay from the pen drive, but it sometimes hangs for a few seconds during write operations (and maybe sometimes read operations too) on the pen drive. I have installed Ubuntu 16.04 on a 32GB pen drive, because my hard disk stopped working.
