How to remove partitions from an external SanDisk Extreme 500GB
Hello,
I recently partitioned the aforementioned SSD using Disk Utility into 3 partitions and one of the partitions isn't working despite mounting and detecting fine. I cannot copy anything. into it although I can seem to reformat it via "partitioning" it again.
I have no data on the drive and am actually trying to just remove all 3 partitions and have the full 500GB available again. I'm running a 2018 Mac mini on 10.15.5.
Please, any info or advise will be most welcome!
Mac mini, macOS 10.15
