1. Transcript | How to Backup External Hard Drive

I want to walk you through a process of backing up your

laptop the first thing that you'll need

is an external drive you might find that

you need an external hard drive like a

big giant 80-gigabyte drive or maybe

something as small as five or six

gigabytes in order to back up what you

need but first, you're gonna have to find

your user folder and you're gonna

have to find your backup Drive so

I'll walk through all those things first

the thing I'm gonna do is I'm gonna I'm

gonna just put my backup drive in this

the case I'm gonna use an SD card and I'm

just gonna put it into the right side of

my MacBook air and we'll see after

sliding that in it should appear there

it is and I've named it dams backup

drive and I made sure that it's it's got

it's got space on it you'll notice is

there's more than one way to backup and

people ask us over time what's the best

way and we find that the best the way

I'm going to show you of actually taking

your home drive and that and

driving it and dragging it into the

backup drive is probably the best way to

do it sometimes that fails and I'll show

you what to do in that case but

nonetheless up here you've got you'll

see that sometimes on your machine you

you've actually got Time Machine turned

on and I would encourage you to go into

Time Machine and turn that off because

indeed the backups that we get from

Time Machine you don't have access to

him because it saves them as the

administrator said plus it uses some

obscenely large space on your computer

sometimes when it's trying to be the

backup and it keeps part of the backup

getting ready to put it onto your drive

so it's like you've got you've doubled

your space just bad idea so here's the

next step the other thing that you'll

see here is if I go down here where it

says finder and I click on that I open

the finder doesn't give me much over

here this is kind of a bare-bones

configuration for being able to see your

the hard drive you're gonna want more than

that my favourite way to look at the

drive is this right here in column but

we can see right here we may not have

what we need there's no there's nothing

that shows me my home drive which is

what I want to back up I do see my

backup drive but I don't see the stuff I

want to back up where it's my stuff

so here let me show you a method for

that so here I'm in my finder remember

once I got there by clicking on the finder

and then going over here for a column

view and the next thing I want to do is

configure the fighter to show me what I

want to see so I go here click on finder

click on preferences and under

preferences I want to modify what we

call the sidebar concept around hard

as long as I'm at it I want to see the

sidebar and in the sidebar if I click

right here on the device and I also

click right here on hard drives it's

gonna show me everything that I need you

can turn this stuff on too but not us

that's not necessary and in your case

let's say your name was Lucinda you

would show up right here so I'm on an

account called student this is just a

generic computer but you would have one

that actually had your name on it but

you don't need that

alright so I'm gonna close the fighter

preferences and you can see whatever

Preferences changes we made of the

sidebar now show up in your sidebar if I

click right here on 109 you SMSs 14 this

is this is the hard drive that's in my

the computer I click on that once and you

can see that there's a folder called

users I click on users look there you

are

so this once again if your name is

Lucinda, you'd show up right here but my

a name is a student so what I actually want

to do is click on and you want to do it

from here if you have your home folder

over here that's not actually the

material that's just a representation of

it but in this case, if I click on users

and here is your home folder and you'll

know it because it has a little home

that is all the stuff that's got you

programs that you've added to the

computer under your own

Applications folder it's got everything

from your desktop

everything you've stored in documents

it's got things you've downloaded it's

got movies you made it's gotten music

that you've made and stored this also

has your I believe this one here also

has your iTunes materials it's got

pictures that you've kept whether it's

in a photo or if it's even if it's in if

you made pictures or movies on

photobooth and then anything you've ever

starred in public which is probably

nothing but to back up it's really this

simple if I want everything I just

the grabbed student I drag it over to Dan's

backup Drive and I drop it down there

I'm gonna say it's gonna copy some stuff

over okay

well that's working I'm gonna show you

an alternative if that fails if it comes

back and says could not copy X and X

Files what you want to do is go back

into dance backup Drive and you want to

take that folder that came over a

student and just drag it to the trash

and empty the trash and we'll start over

but it'll look something like this over

here in student probably what you want

to do is just pick up the stuff that you

absolutely need so for example pictures

and if I hold down my command key I want

my pictures I'm gonna hold down command

again I want downloads I want my

the document I want my desktop everything

else let's say that's where the problem

was

I can then pick those up I can go over

here and I can drop them onto Dan's

backup Drive and they'll go in there

I'm not gonna mess that right now

because this is already in process but

you can see you can customize your

backup a little bit that will work so

once again if you try to drag your home

folder over and you had some sort of

failure this is actually a whole bunch

of hidden files in here

it's got things like program settings

and it's got bookmarks and it's got all

kinds of hidden files and if there's

some sort of permission problem with

that and well let you copy it over this

is a way to get your essential stuff so

that's it it's really that simple

How to use and format your external

storage devises to work with your Mac

many external hard drives come in a

the format that is not compatible with

Macintosh, we can easily fix that using

the built-in Disk Utility the program

within Mac OS 10 we can find that simply

by going to finder we can open finder in

the Applications folder here then

utilities and you will find Disk Utility

an alternative way would be to open your

spotlight search and just type in Disk

Utility so here's the Disk Utility we've

got several options here a very very

the valuable program so what it's showing me

right here on the left is it showing me

all of the external storage devices

external and internal that are connected

to my Mac here you see under internal

this is my built-in iMac hard drive and

then down here I've got an external hard

drive as well as a Kingston thumb drive

so all of these can be formatted and so

there are several options I'm gonna walk

you through those to find the one that

will work best for you to keep in mind that

as we move forward we are going to be

erasing whatever content is on your

storage devise so if you've got

something important on there you're

gonna want to copy it over to something

else before you erase it so we're gonna

select the device we want to use at the

moment we're gonna try our thumb

drive but it's the same exact process

for any other storage device so I've

selected the drive right here and we're

gonna come up and click erase okay this

gives us an opportunity to rename it

whatever we would like it to be called

as well as to choose the format now for

years I've been using OS 10 extended

journaled this is my go-to format for

all things

Matt, however, there are some additional

options that I'm going to go through

here in the drop-down menu, you'll see

the options available to you notice

these two on the bottom ms-dos and exFAT

these are windows compatible options and

they will work between both Windows and

Mac now ms-dos or fat is quite limited

this option I would not really recommend

any longer this one is only for storage

devices with less than 32 gigabytes and

the maximum file size for each file that

you store within that storage device can

be 4 gigabytes in size so that's kind of

outdated

now the new and improved version is

exFAT and if you need an external hard

drive or thumb drive that will work very

well between Mac and Windows you're

gonna want to use exFAT is for

drives larger than 32 gigabytes and

there really are no other limitations so

this is an excellent choice if you're

gonna be taking a drive back and forth

between different operating systems if

however, you're going to only be using

Macintosh hardware or Macintosh

computers I would recommend that you use

OS 10 extended journaled okay so we're

just about ready to format our drive and

one more little bit of information there

is an option if you need to be sure that

what you are erasing will not be

recovered if you had some private

information some financial documents etc

this is a useful helpful tool especially

if you're going to be selling you

the computer on eBay or a hard drive you can

use these security options and you can

select from the various levels of

security to really make sure that that

is thoroughly erased in this case we

don't need that we're just going to

ignore it pretend

it's not even there and we're ready to

we simply select a race depending on the

size of the drive it will take from a

few seconds to possibly a few minutes so

we're all set the drive has been

formatted and now we're ready to go so

we just select done and we can choose

from the menu here and we can just click

eject and now our drive is ready to use

in the new format hey guys I really hope
