Hi, in this video we're going to be
showing you how to clone your Windows
system drive to a smaller drive. So,
you're probably wondering why would you
want to clone it to a smaller drive and
not a larger drive. So, let's say you
have an older, you know, SATA spinning
disc. Uh those are typically a lot
cheaper for the larger disc than the
newer SSD or NVME drives. So let's say
maybe you have a 4 terbte, you know,
spinning SATA disc and you want to
transfer your Windows to a one TBTE SSD
drive because you can't afford a 4 TBTE
SSD drive, uh, you could do so. Now,
this is assuming your Windows data will
fit onto the smaller drive. So just
because you have a 4 terbte Windows
drive doesn't mean Windows is using all
of it, unless of course you are. All
right, so we just have this test
computer here. So this is a 100 gig
drive here with Windows on it. And we
have this new unallocated 60 gig drive.
So we're going to be going from the 100
to the 60. So from larger to smaller.
All right. So the catch is that this
will have to fit on the 60 gig drive. So
just because this says it's 100
gigabytes doesn't mean it's using all
100 gigabytes. So if we right click on
it, go to properties,
you can see we're only using about 27
gigabytes. So that will fit on the 60 GB
here. And of course, you have this extra
200 megabytes here and 735 megabytes
here because we're going to have to
clone all of these partitions. So this
total needs to be able to fit on here.
All right. So to do so, we're going to
be using the free haso disc clone
software. So they have a professional
version, too, with extra options, but
the free version works just fine. So
once you download it and install it,
just open it up.
All right. So, we have partition clone,
disc clone, and system clone. So, we
want to do a system clone since we're
cloning our operating system. All right.
So, here's the disc that we want to
clone. Disk zero, which matches here,
and we want to clone to disk one, which
is right here. So, we want to pick this
one here because this is the one we want
to clone. And if you check this box
here, that will select all of the
partitions because we need all of these
partitions for Windows to run. So we'll
click on next here.
Okay. Now we need to select the location
we want to clone to. So we want to clone
to disk one.
And there's this advanced mode, but you
can't use advanced mode with the free
version. And then we have this clone as
MBR, which you're probably not going to
use unless you're working with some
really old computer that's not using
GPT.
All right, we'll click on next.
All right, so now here you could adjust
your disk layout. So you can see it's
going to use the whole thing here and
you can click on each partition and it
tells you what it's doing here. So if
you wanted to shrink this down and have
some unallocated space left, you could
do that, but you probably don't want to
do that unless you have a good reason to
do so. All right, so we have a couple
options here. So sector by sector clone
partition, we want to skip that. So
reasons for skipping this um it's
because it ignores the disc size and if
you do check it then the software is
going to try and copy every single block
from your larger drive to your smaller
drive and since the target is physically
smaller the clone will fail immediately
because it runs out of space to put
those empty sectors and is very slow. So
that's another reason not to use this
option. All right. Then we also have the
disk alignment section here. So we're
going to change this to 4K. So this is
because traditional hard drives use 512
byt physical sectors but modern SSDs uh
use 4K sectors. So this type of
alignment ensures that the logical
blocks Windows writes perfectly line up
with the physical blocks on the SSD. And
it could also boost the speed because if
partitions are misaligned, a single 4K
write from Windows is forced to span
across two physical sectors of the SSD.
then the drive has to read both, modify
them, and write them both back. And it
also extends the lifespan of your SSD.
All right, so now that everything's
configured, we'll click on proceed. This
tells you all the data on the selected
disc will be destroyed. So make sure you
don't have anything on there you want to
keep. So I'll click on yes.
All right, so it's initializing. Then
you have some options here for when it's
done. You could have it shut down,
reboot, sleep, hibernate. We're just
going to leave it at do nothing. All
right. So, I will pause the video and
then be back when this is done.
All right. So, the clone is complete.
Only took about two and a half minutes.
That's because this is just a test
computer with very small drives. So, of
course, the size of your hard drives and
the speed are going to determine how
long it takes. All right, we'll click on
finish.
All right, let's close this out here. Go
back to disk management. All right, so
now you can see here we have our disc
cloned. And you can see here at the size
difference, 100 gigs down to the 60 gigs
here. So now what I'm going to do is
shut down the computer, take out the 100
gig drive, and then boot it up with the
60 gig drive, and we'll make sure it
works.
All right, so we got a Windows logo, so
that's a good sign.
Let's go ahead and log in here.
Right.
So, we got our desktop. So, let's check
out disk management here.
Right. So, here is our 60 gig drive here
with no other drives configured.
Take a look at file explorer.
Right. 38 gigs free out of 60. All
right. So, you can see it did a pretty
good job there. It's pretty easy to do.
All right, so I will put a link in the
description where you can download
layout disc clone and then you can try
it out for yourself. All right, thanks
for watching and be sure to subscribe.
