What came in

A customer brought in their Lenovo Yoga A940 all-in-one, a computer they use for business. The C drive, a 256GB NVMe SSD, was simply too small, and they needed more room without starting over on a fresh Windows install.

Why we did not just reinstall Windows

On a business machine, a fresh install means reinstalling every program, re-entering licenses and rebuilding settings. A full sector-by-sector clone copies the drive exactly as it is, so the applications do not get confused and everything opens the way it did before.

What we did

Decrypted the drives first. Both the Windows (C:) drive and the Data (D:) drive were protected with BitLocker, so we fully decrypted them before touching anything. Encrypted drives need to be decrypted first so the clone copies over cleanly.
Removed the drives and cleaned out the dust inside the computer while it was open.
Ran a full sector-by-sector clone from the original 256GB NVMe SSD to a new 1TB NVMe SSD.
Installed the new drive and confirmed the computer booted up and worked the same as it did before.

The result

The computer boots up the same as it did before, with every program and file right where the customer left it. The C drive went from 256GB to 1TB, so there is a lot more space, and because the new drive is a newer NVMe model, overall speed improved too. See our SSD upgrade service for how drive upgrades work at our shop.

Dave's tip: running out of space on C? You do not have to start over. A proper clone moves everything to a bigger, faster drive, and the computer comes back exactly as you left it. For business machines with BitLocker, the drives get decrypted first so nothing goes wrong along the way.
