I have a HDD that's failing so I ended up getting a new HDD to replace it. Cloned it and that's fine, plugged it in via USB adapter and can boot to it via changing BIOS. But if I remove old HDD & plug new one in slot it's not recognized. If I put old HDD back in it's fine. What am I missing?

Just to confirm the precise situation that's involved here...

Are you indicating that if you boot the system from the newly-cloned "new" HDD while that HDD is connected to the laptop as a USB external device, the system will boot to the OS (Desktop) of the newly-cloned "new" HDD? Is that what you're indicating?

Is that what you mean when you say the newly-cloned "new" HDD is "plugged in via USB adapter and can boot to it via changing BIOS."?

And if so, while the newly-cloned "new" HDD is still connected to the laptop as a USB external device and you remove or disconnect the internally-connected "old" HDD, are you indicating that you can boot to the OS (Desktop) booting from that USB externally-connected "new" HDD?

But when you...
Hi there Kieran68,

Do you have a laptop or a desktop machine?

The new HDD is not recognized at all right? If this is the case, then I would say that this is strange. If the drive is not recognized at all, my suggestion would be to troubleshoot the connection. You can attach it to a different SATA port with different cables.

You adjust the boot order once you switch the drives right?

Cheers,

But when you internally install that newly-cloned "new" HDD in the laptop the system will not boot to the OS.

All the above comments/questions are just a suspicion on my part that's what's really involved here is a disk-cloning operation that has gone awry for one reason or another. So that the "new" HDD is NOT a bootable device. That when the system booted to the OS (Desktop) while the newly-cloned HDD was still connected as an external USB device, the system, was still booting to the internally-connected HDD and not to the cloned USB-connected HDD.

Naturally I may have misunderstood your query and may be wrong with my "diagnosis". So pardon me if I am.

1. We'll assume your "old" internally-connected HDD (even though it's "failing") still boots the system and basically functions without problems. If that is NOT the case don't bother reading any further. Capiche?

2. So repeat the disk-cloning operation as you previous did with the destination drive - your "new" HDD - connected as an external USB device. Immediately following what appears to be a successful disk-cloning operation, shut down the system and uninstall the "old" HDD and replace it with the newly-cloned HDD.

See if that resolves the problem.
