Can't format my 64gb msd card

[Oyeve]

About a year ago I used some weird program to force my 64gb sandisk msd card to format in fat32 so I could use it with my 3ds. I got rid of the 3ds and now when I go to format the card, depending on the system I use to format (ie, PC, Mac, Linux) it either says it can't format or says it was formatted but when I refresh the 3ds stuff shows up. I cant find that program and have tried many others but I get the same results. Any ideas?

Was it a format utility made by HP?
I seem to recall they were the only ones to release a utility that allowed you to do that... I have no idea where that is now, so I can't check this moment.

A camera or phone will probably format it.

Tried several. Same deal.

On linux try

dd if=/dev/zero of=/dev/sdWhatever bs=16M count=1

That should wipe away and all partition tables, even if it's got some funky partition alignment. Then, just to be on the safe side, reboot before trying anything further. Afterwards, it should appear as an unpartitioned device.

You might want to look at the partition table, before you do it, though, and note the starting sector, so you can align any new partitions to that point.

Positive. Tried other cards and adapter combos.
