Changing the drive letter of the non-boot drive

[Phudgel]

I recently upgraded to a SSD and fresh-installed Windows 10 onto it.

I have been running on only the SSD for now, but would like to use my old hard drive as a storage drive for documents and programs that do not need to take advantage of the SSD.

Since they both have Windows installed on them, my computer only recognizes one, as they are technically both the C: drive.

So, since Drive Manager does not see both, I was wondering if it would be possible to boot Windows on the HDD and change the drive letter from there, since I do not intend to boot windows on it ever again. Would this be possible, and if so, would the data on it still be accessible if the drive had a different drive letter? Or would it just be best to move whatever data I would still want to an external hard drive and format the HDD and copy it over once it has a new drive letter assigned through Drive Manager?

Thank you very much.

When you have drives like that it the drive you boot from will be the C drive and any other drives you have plugged in, windows installed on them or not, will then show up as D drive and on.

I would plug them both in, make sure you boot off SSD, and then go into Disk Management and see if the drive is even being seen. If it isn't then check how the drive is hooked up. If it is being seen it may not have a drive letter. Right click on it and add a drive letter OR just delete all the partitions if there is nothing on then and then make one new big one.
