I started getting SMART warnings on my 1TB WD disk, so to prevent losing the data, I went to buy a replacement. Since the disk was almost full, I decided to buy a 2TB one (a Seagate). I installed it, reformatted (verifying it was 2TB) and went to look how to clone the failing one.

I looked up on the net how to copy the data over in such a way as not to lose any system properties etc; one of pages suggested Macrium Reflect Free - I didn't need anything fancy, so I got it, the cloning went through, and as I went to check the result, there was the cloned partition, exactly the same size as original. I went to disk manager - and it's 2TB there. I ran the disk through chkdsk but it didn't help.

F: is the old, failing disk. E: is the new one.

enter image description here

What can I do to make it appear as 2TB in the OS, not just disk manager?

    Does this answer your question? [Easiest way to move my Windows installation to an SSD?](https://superuser.com/questions/252675/easiest-way-to-move-my-windows-installation-to-an-ssd) – music2myear Aug 10 '20 at 01:26

    @music2myear No, not even remotely. 1. Working post-factum repairing existing Macrium Reflect snafu, 2. not the system partition, 3. to a larger drive. While most of the solutions would work, they are massively overcomplicated for my situation - this is not the system drive, WinPE or other OS is completely unnecessary. As you can see the required solution was 4 lines in terminal. Using the others would be "shooting sparrows with a cannon". – SF. Aug 10 '20 at 07:11

Most filesystems have their own "size" independent of the underlying device (partition). It seems a bit like Reflect simply dumped the original filesystem into a larger partition, but did not update any NTFS structures to match.

From within Windows, you can probably fix this via DISKPART. Select the volume using list vol and select vol num, then grow the filesystem using extend filesystem.

Within Linux, you can use ntfsresize on the partition device.
