Disk not seen.

[YoyoBoy]

Yesterday I got a fresh new hard drive and installed Windows 7 onto it, then upgraded it to Windows 10. To make sure all my data was safe from the process, I removed my work drive from the computer. For some reason, when I pop my work drive back into the computer my new Windows install cannot see it. I freaked out for a second, but then I put my old Windows disk in and that can see it just fine.

Any ideas?

Thanks.

Never mind. It somehow magically fixed itself. Weird.

Oof! Now I have another problem with that drive. I can't change the drive letter. I just want it to be D. Anything else I stick in there ends up as D, but I can't switch this one. I assume it's because Disk Management says it has a Page File on it (which I can't see), so I went into the Performance Settings and made sure it wasn't System Managed, but that didn't do the trick.

Any ideas?

Thanks.

Never mind, once again. I realized that the drive still belonged to the old Windows disk, so I popped that back in, made the drive non-system-managed, and put the new Windows disk back in, and all is good.
