Lightroom Catalog gets corrupted when I swap SSD into my other editing computer.

[haring]

I have 2 identical computers with the same Lightroom running on them.

I usually work on my home computer editing wedding photos in the morning. When I need to go to the office I take my editing SSD drive with me and istall it into my other PC. This is not an external SSD but a regular secondary drive I insert into the computer and close the housing.

Every time I swap the SSD drive the Lightroom catalog gets corrupted. The backup copy works so I use that all the time but the main catalog is corrupted.

My question: Why does it create a problem that I remove the SSD and insert it into another computer? Both computers has the same processor, motherboard, etc. I make sure I completely shut down the computer before I remove the drive.

Any ideas?

Are you terminating the Lightroom process before you relocate the drive?

What do you mean by corrupted? 
Screen capture of the message?

Is this new or always happened?

Are all the LR sub-folders within the LR folder?

Do the images go with the SSD or are they elsewhere?
