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

Make sure "Show All Devices" is selected from the Disk Utility "View" menu, select the top level of the drive and click "Erase".
