Invalid checksum and invalid tree

Hi all,

Got an issue at my MacBook Pro 17" early 2011

Running High Sierra 10.13.6.

I have installed a SSD 1Tn about a year ago. Everything was fine for a decent period of time. Now I'm suffering from the fact that sometimes files are not visible after saving. Next I'm not able to empty the trash, whatever I try. Running first aid it tells me that the FStree is invalid and that the checksum is invalid.

Recommended is to format the drive, do a restore from time machine.... That's possible of course.

My question is, is the fault causing the error not restored as well?

HTH soon.

Thanks in advance and best wishes.

MacBook Pro 17″, macOS 10.13
