Change Lightroom re-sync behavior after an external hard drive sleep recovery?

I store my lightroom catalog on an external hard drive.  This external hard drive does not wake up from sleep once the computer enters that state and returns from it (i.e. it effectively remains disconnected).  If I have an open LR session on that catalog before the computer goes to sleep, when I return to my computer LR will show an error message effectively saying it needs to shut down.  After the shutdown and relaunching of the catalog, LR will say it needs to check the integrity of all the files.  After the check is complete, LR will launch but now the sync progress counter shows it needs to re-sync all of my photos.  I would have no qualms with this except I have over 15K photos in LR sync and it's taking about 24 hours to resync even though I've made no edits.  The syncing slows down the responsiveness of LR to the point that I don't feel like making any edits while it's in the state.  Can this behavior be changed in future LR releases?

To replicate my issue for yourself, I believe you just need to disconnect any external drive with an open session on a LR catalog that has synced collections and then reconnect/reattach the drive and restart the LR session.
