We couldn't create a new partition or locate an existing one

"We couldn't create a new partition" — messing around with partitions can be a bit risky if you’re not careful — I’ve seen it go sideways before. The biggest danger is losing data. If you accidentally delete or format the wrong partition, you could wipe out important files. Also, if something goes wrong during resizing or creating a new partition (like a power outage or a glitch), it might corrupt your disk or make your system unbootable.

If the problem of "We couldn't create a new partition" hasn't been solved yet. From personal experience, I’ve tinkered with partition tools before, and while most times it goes smoothly, there’s always that tiny chance something can go wrong — especially if your disk is already having issues or if you skip backups. That's why I always recommend backing up everything important before doing any partition magic.
