Sorry you’re having problems with your drive, but I can assure you that TabloRipper lacks the capability to corrupt your hard drive. And it does NOT affect the operation of your Tablo.
If it’s ripping a show in the background, the temporary output file may not be closed properly if you pull the plug instead of shutting down properly. But that’s the extent of the damage inflicted and will self-correct next time the program wakes up and starts ripping again.
As always, feel free to use any one of the many other options instead of TabloRipper.
PS - Since TabloRipper is a third party app, you’ll want to post support requests here where I’m more likely to notice.
