01The problem

A disk copy is never a clean 1:1 match

New drive bigger? The spare space sits unused unless you carve it up. New drive smaller? Fat partitions simply won’t fit, and the clone can’t start.

That’s why Hasleo Backup Suite asks you to pick a disk layout strategy before the clone runs.

02Meet the tool

The Clone module — layout control built in

Click Clone in the left bar, choose System, Disk or Partition clone, then select your target drive. Before anything is written, you preview the exact target layout — and decide how to place it.

Clone Pick type Set layout Proceed

Four strategies: EditAutomaticKeepKeep Size. Each controls size, position and alignment differently.

03Edit disk layout

Take the steering wheel

Click any partition, then drag the sliders or type exact numbers. You control the free space before, the partition size, and the free space after it.

Sliders + numbers = total control

Handles the case cloning to a smaller SSD — shrink manually so everything fits.

04Automatic disk layout

Sit back — it fits the drive for you

Hasleo sizes and positions every partition to use the target disk’s full capacity. The editors lock themselves; all you do is confirm and click Proceed.

Nothing to tune — just Proceed

Best when you just want a clean, working result fast.

05Keep disk layout

A mirror of the original

Every partition keeps its exact size. If the target is larger, the leftover space stays unallocated — and only the sector-by-sector option remains configurable.

Same sizes, spare space left free

Ideal when the target disk is the same size as the source.

06Keep partition size

Same sizes, new places

Sizes are locked, but you can drag partitions or edit their start and end offsets to reposition them. All other settings — like alignment — stay fully open.

Move it, don’t resize it

Handy when partitions only need a better position, not a new size.

07The workspace

Three areas. That’s it.

1 Target disk layout — preview what will be written.
2 Partition editor — adjust size and location.
3 Advanced settings — alignment, partition type, sector copy.
08Alignment

For SSDs, 1M is the sweet spot

Disk alignment sets where each partition starts. It matters most for SSD performance.

1M
Recommended for SSDs
1MB alignment — always 4K-aligned for the best SSD speed.
4K
4K
Start each partition on a 4KB boundary.

For Windows XP and older systems.

Windows Vista and later already align new partitions to 1MB — match that and stay fast.

09Safety check

Before you hit Proceed

1 Back up the target disk. Everything on it gets overwritten during cloning.
2 Check capacity. Target must hold at least the source’s used data.
3 Connect the target. Use a SATA-to-USB cable on laptops with one drive bay.
4 Sector-by-sector? For exact copies — it’s slower on purpose.

Resizing never touches the source disk — it only shapes the target.

10Quick answers

Still unsure?

Clone to a smaller SSD?

Yes — as long as the target holds your used data. Edit mode shrinks manually; Automatic resizes intelligently.

Is the source disk affected?

No. Only the target layout changes — your source stays exactly as it is.

When use sector-by-sector?

For an exact bit-for-bit replica — data recovery or compliance. It copies empty sectors too, so it’s slower.

⚠ Double-check nothing important is left on the target first.

You’re ready

Your new drive, sized perfectly

Pick a strategy, preview the layout, and click Proceed. Bigger or smaller — every partition lands exactly where it should, ready to boot.
