A close friend has a PC that he upgraded from Windows 7 -> 10 some time ago. Everything was running fine, but recently when powering up the box he began to see S.M.A.R.T. warnings from the BIOS referencing his (only) internal hard drive, with an option to continue. Windows 10 would start (albeit very slowly) and it, too, would report that his disk was failing.
He had a single, internal 1 TB drive partitioned in half, with the OS on C: and data on D:. I got him a 2 TB drive to replace the failing one, and used Macrium Reflect to create a Windows PE boot CD with Reflect on it. After booting from the CD and waiting for Reflect to load, I cloned the partitions off of the failing drive onto the new drive (connected via a USB drive bay). The clone operation created 2 partitions on the new drive with the same size as the originals, and left about 1 TB of space unallocated on the new drive. It took just over 8 hours to complete that clone operation.
Once the clone completed (with no reported errors), I swapped in the new drive and attempted to start Windows. At first it appeared to be working, but (Windows 10?) apparently had issues with the new drive, reported doing some diagnostics, then displayed a screen with "Attempting Repairs" and the rolling "busy" graphic. It's been like that for almost 24 hours, and I'm beginning to have doubts that anything is happening at all. The drive activity LED is on solid.
Is what I have attempted even possible? If so, why would Windows 10 have a problem with the new drive? I thought (perhaps mistakenly) that a disk clone would take care of copying all the information required to boot the OS (MBR, etc) and that after the clone it would simply be a matter of swapping the new drive in. (Yes, I know, silly me.)
Thanks for any advice / opinions
