I’m currently unable to mount my 1tb samsung 860 evo ssd and my 3tb seagate hdd. If anyone has any idea what’s wrong, it’d be really helpful. I’m new to manjaro but I have a little bit of experience in other distros like ubuntu and mint. If there’s any other info that I can post that might help, please let me know and I’ll post it.

Do you have any mountable partitions/filesystem on those two drives?
Please post output of

$ lsblk -fs
$ parted -l

I should have mountable partitions but I can’t seem to figure out why I can’t mount them. They worked fine on mint for me.

Well they are both there at sda and sdc
What do you mean that they arent mounting?
They arent visible? You attempt a mount and it fails? or ?..

They weren’t visible for me but I was able to retrace my steps and realized that I had applied the “boot” flag to both of them. I unchecked it on both and now they are both visible for me.

Hello,
