Read only READER partition on linux

timoc · 07-22-2018, 10:34 AM

Hi,

I have a PRS-T1, with the 1.0.04 Fimware on it. I am about to upgrade the firmware, but i cannot write the os upgrade to the READER partition when i mount it on Ubuntu.

I tried to remount it as rw, but no luck. I tried to use the onboard REFORMAT option, but it kind of hung and did not work.

Is there a way to fix this? Will an OS upgrade work?

Any help appreciated.

Hi,

Filesystem errors can cause mount to mount the partition read-only, so that might explain it. Though you'd expect to see an error message when you mount it, and also in dmesg. Then writing files would give the error 'Read-only file system'.

In that case you could umount it and run dosfsck to repair it. Add the -t option to check for bad clusters.

Or another thought, if you're only seeing the error 'Permission denied' when you try to write the files, then it could be you mounted it as root (without -o user), then tried to write the files as non-root?
