Windows 10 - Can't write to secondary/tertiary drives

After my old drives began having issues a couple of weeks back, I went ahead and replaced all 3 with 1 SSD for the OS/frequently accessed files and 2 HHD for whatever storage.

Finally got everything backed up, old drives removed, new ones installed. Had zero issues installing Win 10 from USB to the SSD but I seem to be completely unable to install programs to either of the HDDs. Whenever I try, I get some variation on the error message "You don't have write access to the destination drive".

The drives do seem to be in working order, as ducking into either one in explorer will show the system-installed hidden directories just fine; I just seem unable to write to them myself.

I don't recall having this issue with my old drives, and I've already tried a fix I found via Google where I disable admin approval messages. UAC is disabled. Anyone else encounter a hitch like this where the primary drive is fine but not the others?

I've never seen this with newly partitioned and formatted drives before. I have seen it before with an old drive, and rather than take ownership of every folder and file on it simply stripped all of the permissions by converting it to FAT32 filesystem which does not support permissions at all.

Obviously you'd need a 3rd party tool to format the HDDs as FAT32 but it's a last resort available in case you can't get it working any other way.

If you installed Windows to the SSD when no HDD was attached and added the HDDs later, there shouldn't be anything bootable or important on the HDDs when viewed in Disk Manager.

The old drives are packed up and in my closet for the time being. The only connected drives at present are the new ones. The SSD was set up during the Win10 install, the HDDs I used the disk manager to set each up a simple volume and then formatted with the default NTFS options.

I can't imagine why there should be any write permission errors.
