I’m a new Photolab user and have noted permanent image corruption on three or four occasions - it always manifests as a solid black bar, horizontally or vertically, and has occurred on both RAW and TIFF images, verified by viewing the files in other software.
In my case, I’m convinced my processing/ redundancy/ backup strategy is the cause, NOT PL or hardware issues.
My system was initially configured as follows;
- Photos folder automatically synced both ways (mirrored) with NAS over the LAN.
- Photos folder automatically synced both ways (mirrored) with external Thunderbolt USB SSD drive when plugged in.
- Photos folder on NAS shipped to cloud storage automatically at stupid-o-clock in the morning.
I believe my mistake was setting up 1) and 2) to run in real time whenever changes in the monitored folder occurred. I use PL, Photomechanic and Topaz at various stages in my workflow any one of which could be writing or reading the file at the same time as each other PLUS the NAS sync agent PLUS the SSD sync agent and so on - on reflection, a recipe for all sorts of trouble 🫤
1 and 2 are now triggered manually when I’m done with photo editing, and I make sure the first thing I do is create a virtual copy and work on that rather than the original whilst I review whether the problem has gone away.
