I have the same problem related to this entry "Can't see my old sata hdd from system running on new ssd", only that have two 500GB HD. Somehow I was able to duplicate EFI and Boot partition, and now I have Windows 10 being installed on both HD. But when I boot from one of them, I can't see the contentes of the other from Windows. BIOS recognize both, so I can choose which one to boot from.

Hey there, @MisterVSE!

I'd recommend you try booting with the HDD that you wish to boot from, while having the other one unplugged from the system! If it boots without any issues, you shouldn't have any issues reformatting the now secondary drive from Disk Management as @Hellfire13 implied.

I'd also go to BIOS and check the boot priority, so that you don't encounter more confusion with the system when having both drives connected. Keep in mind that once you get rid of the Windows OS onto the secondary drive, you won't be facing these boot confusion issues.

Either way, backup all your data from the system somewhere off-site before tampering with the storage again. Better safe than sorry, right? Always remember that "backup" means that you have your data stored in at least two (2) locations. Moving data from your system drive to an external hard drive or keeping in on two internal HDDs is not a backup, unless there is already a duplicate of the file on a different drive stored elsewhere.

Hope this helps. Keep us posted with the details & troubleshooting! :)

Hello, Guys. Thanks for the attention. As for the problem, here's what I can add to the problem::
1 - At one time I had duplicated my operating system HD (both with 500G) and when boot with first, can't see the second and vice-versa.
2 - The second HD are recognized by BIOS, as I can choose any of them to BOOT from. But it doesn't appear on the Windows Computer Management panel, that shows only the booting HD plus the CD drive.
3 - The same happened when I attached an HD with only NTFS partition, even without OS in it.
4 - Thanks god, I have migrated last night, both of HD to Windows 10 (Oh yes, forgot to tell, both were Windows 8, original from Lenovo as it is my Desktop) and I could see (from booting the second HD, didn't have time to test otherwise yet) the second HD recognized and assigned F: to the drive. So problem disappears now, at least from my point of view.
5 - Nonetheless, I had difficulty to view this same HD when I tried to mount it in another Lenovo (Twin with this one) that was already migrated to Windows 10. But this other problem I'll see if I have to pursue further in another occasion as I can't disturb this machine because it is in production. It seems when the two are Windows 10 it is fine. The problem was with the Windows 8.

maybe it was missing a drive letter in win8...u need to always look at disk management first and then in bios, when u dont find a drive in computer/my computer, assuming that is what u r calling "windows computer management"...u can just type disk management in the start menu to open it...

anyways, glad its working for u now...cheers...

---Yes, Hellfire, that is what I want to tell, but it happens my Windows is in Portuguese, and I am not sure the correct translation of what I see here, sometimes. The Windows Disk management didn't show the HD... Just the Booted one and the CD drive. BIOS shows it all right... Anyway thanks for the quick reply. :-D
