I'm still on LR4. Until recently I had no problem syncing between my two computers over our LAN using SyncBackSE. When I replaced one of the machines with a much faster PC with an SSD (Solid State Drive) as the ""C" drive for programs and a standard SATA terabyte drive as the "D" drive for data, including my Lightroom files and catalog, the catalog is looking for "C" and not "D" where it is now.
How can I fix this without messing with hardware? For example, is there an INI file somewhere that indicates to LR where the data is?
Thank you very much for your help. All works well now. That article is worth saving.
