I am not sure if I am the root cause of this problem but this is what I did:

I wanted latest ubuntu and latest linux mint together on my thinkpad laptop. Windows 7 was already there.

I already had mint. So I put in the USB with ubuntu image and started installing ubuntu. I chose to install side by side.

It was taking a long time to finish defragmenting and partitioning. I decided to give up as I became a little impatient and I pressed the skip button. After the skipping, I realized that the partitioning was complete and went ahead with installing ubuntu.

Now the linux mint OS starts reporting the file system as read only at least once every day and I have restart and tell the OS to fix errors in hard disk. After I press F key, the system fixes the issues, restarts and all is well again.

Is there some way to fix the issue permanently. I think reinstalling will solve the issues, but I can not do it as I have a lot of data and I will have reinstall and configure a lot of softwares that I use daily.

I checked the smart check in disk utility and the hard disk seems to be fine

Also I checked both the partitions for errors with disk utility and the report says they are fine.

Is there something I can do before I reinstall?
