all right so you have a external hard
drive that you used to use on your
Windows computer and you just put it
into your MacBook now you're trying to
transfer files from your MacBook to your
external hard drive and you're not able
to for example under devices here you
can see you 32 this is my external hard
drive ok now if I wanted to move some
from external hard drive to my macbook I
have no problem so I can move this
folder to over here a problem however if
I want to move it back in from my Apple
computer to my external hard drive see
that round circle with the AK with the
line through it I can't okay see I can't
do it now why is that
well I double tap on my u32 over here
and I go down to get info you can see
the reason is is because my filesystem
is formatted in NTFS basically we're
only windows can write to it now with
NTFS your Mac your Apple computer
that'll be able to read it but it cannot
write to it so what do we do well if you
want to if you format it in a fat
filesystem fat32 or exFAT then it's it's
compatible both ways it can you can
transfer to an apple to a Windows and
vice versa so what do we got to do now
basically what you have to do now is
whatever files the folders you want to
save them you can simply do is as drag
you can drop that once your Apple
computer I can just drop it right here
onto the my my desktop here and the
thing is I can't drag all of these
because these files are way too big so
I'm just going to show you for example
just we're just gonna save this one here
I've already backed us drive up my
windows computer goes again my Apple
computer this is like 300 gigs right
here so anyway so once you move
everything over to your your Apple
desktop then what you can do is click on
his magnifying glass in the top right
hand corner then what you want to do is
you want to type in Disk Utility up
right here
there's this toady right here you can
DoubleTap on that to open that up and
here we go so if I look down the
external down here you can see this u-32
can that's my external hard drive let's
see here this is a 500 gig er if I click
on the second one here its Wow I used
this is like almost 300 gigs so I don't
have enough room on my Apple computer so
I'm just showing that one folder here as
an example so you just want to go and
tap on your external you may only have
one on here okay if you have stuff on
there you don't have to click on the
first one here is fine then you want to
go ahead and tap on your race then you
go ahead and name it and then under
format now there's several things let me
just go over these really briefly okay
this oh oh s X extended it's basically
the default for the Apple Apple computer
but you can only it's only for Apple ok
the same thing with this OS X extended
this is when this one's case sensitive
though this one basically is for for
example like let's say you have a a file
named file dot docx and another file
name file dot docx but the FS
capitalized then you're not going to be
able to transfer that over anyways the
default recommended for the apples is
top one here and then we'll do go down
here and listen carefully with these two
okay we have a ms-dos pad this is
basically the fat32 the guys remember
that from it all stays and then we have
a newer fire file system here called the
exFAT now what is the difference here I
mean for me I always go with the fat32
but let me just give you a quick
information between these two you can
decide which we need so the ms-dos right
here is fat basically this is fat32
again now you can transfer between both
of these you can transfer windows and
app ok but this one here you can do
trick you can transfer from like Windows
Apple Linux you can also transfer files
from gaming systems like PlayStation 3
Xbox 360 that we the only limitation
that you're going to have on this
one is you cannot transfer files more
than four gigabyte in size okay now
you're going to be moving any file
that's more than four gigabyte in size
and you need to go with the exFAT okay
there's the one that I recommend I mean
for gigs like come on if you're
recording any videos in 4k you know
decent length of videos you're gonna
have more than four gigs even if you
download it put a DVD on there it's
gonna be more than four gigs anyways
I recommend this one if you're not gonna
be chess profiles on gaming systems and
you may have more than four gigs the
transfers then just go with the exFAT
here so right there and if simply we're
gonna top on you race here and remember
it is going to erase everything give us
a second here and this has basically
asked me if I want to back up a time
machine you can decide later you can you
can use it as a backup this I just don't
I'm just gonna go don't use okay now we
are done that was quick that just format
it like 300 gigs okay and then from here
what we can do is let me go ahead and
open up a finder here let me here's my
my u32 here's my external hard drive let
me just go in to get info and let's
check this out now oh wow there it is
exFAT I got 500 gigs available and then
from here when you can do is is your
file that you saved onto your desktop
you can just drag and you can drag and
drop that back onto there and that's
pretty much it you're good to go you
guys you have any questions or need any
help just comment below alright thanks
