- To create a new logical drive in an Extended partition, right-click on the free space on an Extended partition where you want to create the logical drive, and then click New Logical Drive. In the New Partition Wizard, then click Next.
- One installed, you can access your external hard drive much the same way you would access your internal drive or another device connected to the computer. Backing up your data is as simple as clicking and dragging those files you wish to back up into the external drive. This is perhaps the best solution for backing up your hard drive.
To format the drive, attach it to your system and open Disk Utility, and then perform the following steps: Select the drive device in the list of devices, which is the item above any storage.
Installing An External Hard Drive On A Mac PlusThis tutorial also applies to any SCSI Mac.
The Mac Plus was the first Mac with built in SCSI hard drive capabilities. If you plan on running system 6 on the Plus, (and you should as anything newer will be slow just as running OS X on a pre-G3 Mac is slow), you can easily put all the programs you'll need on an 80 meg drive. You can go all the way up to a 1 gig and up to 4 gigs if you are running system 7, 10 gigs if you are running 7.5.5.
What you need
Hard drive case with power supply - see the pic above. Thephone book size box is the drive case with power supply. This casehas scsi connectors on the inside and attaches to the scsi port ofthe Mac. If you can find one, you should buy the Apple brand SCSIhard drive case - they are built like tanks and the power supplieslast forever. Of the hundred or more that came into Goodwill when Iworked there, 99% of them worked fine, some were almost 13 years old.The case pictured above is an Apple case. Some older cases have BD 25connectors and not Centronics 50 pin connectors. You'll need a DB 25pin to DB 25 pin scsi cable for these cases.

A Drive
You can use pretty much any SCSI drive, Mac or PC in a Mac, but ifit's not an Apple brand, you'll need a third party (Non-Apple) driveformatter program such as LIDO,Anubis, FWB, etc. You can also d/l the patchto Apple's HD SC Setup which allows it to see and format 99% of thirdparty drives.

Installation
Open the drive case. If it's an Apple brand, you'll need a tinyflat head screwdriver to pop back the plastic tabs on the sides andrear of the case. This is not easy to do without breaking the tabs,but if you do, the case will still snap shut securely. On otherdrives, unscrew the screws as necessary. When you get it open, youshould see a ribbon cable, power supply, possibly a hard drive liteconnected to a cable and a scsi ID selector cable. You'll need tounscrew the present hard drive and remove it if there is one. Justdetach the cables and pull it out. Now put the new drive in in thesame way. Attach the ribbon cable to the rear of the drive. There isonly one way the cable will go in. If your case has a scsi idselector cable, see if it will fit onto the SCSI ID jumpers on therear of the drive. Some drives don't have these. They are usually sixpins sticking straight out of the bottom of the drive. If you connectthe SCSI ID cable, you can change the SCSI ID by switching the switchon the rear of the case. If you do not attach teh SCSI ID connectorto the drive, you'll have to open the drive and change the ID withjumpers. If you are using a drive from a PC, you may have many pins.If this is the case, do a search on the web for the part number ofyour drive and you'll probably find the pinouts. For a quick anddirty test of the drive, leave the scsi id connector off and attachjust the ribbon cable (scsi) and power cable to the rear of thedrive. Don't put the case back together yet, you may still need tofool around inside it.
Attach the scsi cable to the back of the Mac with the DB 25 pinconnector. Attach the Centronics 50 connector to the rear of thedrive case.
**IMPORTANT** If you are usinga Mac Plus, you'll need a terminator connected to the secondCentronics port of the hard drive. This terminates the signal. TheMac Plus does not have built in termination, all other Macs do. Youmay or may not need termination on other Macs, you WILL need oneALWAYS on a Plus. If you have more than one SCSI device attached toyour Plus, the terminator is usually on the last item.

If you get a flashing question mark on your Mac's screen, youeither have a bad hard drive, no operating system on the drive or theoperating system has been damaged. You'll need to boot off a floppyand reinstall the OS. Get your Mac OS 6.08 floppies here,7.5.3 here.You'll need 4 megs of ram in the Plus to boot and load 7.5.3.

If you read my previous post about how to format an external drive for Mac, you know that I bought a 2TB Seagate Expansion external hard drive and managed to create two partitions on the disk — one for Mac backup purposes, and the other for personal use.
In this article, I’m going to show you how to back up your Mac data to an external drive. You should back up your Mac on a regular basis, especially if you’re planning to perform macOS updates.
I did this several weeks ago while preparing my MacBook Pro for a system update. You may also be interested in taking a look at the macOS Catalina slow issues we encountered during that process just in case you also want to upgrade your Mac to the latest operating system.
Please note that the backup tool that I used is Time Machine, a built-in app provided by Apple. If you want to back up your Mac data without using Time Machine, there are also other third-party Mac backup software worth considering.
Where is Time Machine on Mac?
![Setting Up An External Hard Drive For Mac Setting Up An External Hard Drive For Mac](https://www.howtogeek.com/wp-content/uploads/2018/04/img_5ac1c0ee675df.jpg.pagespeed.ce.ZAgARfQpCt.jpg)
Time Machine is a built-in app within macOS ever since OS X 10.5. To find it, click on the Apple logo on the top left corner of your screen, then select System Preferences.
In the Preferences Pane, you’ll see the app located between “Date & Time” and “Accessibility”.
What does Time Machine Backup?
Time Machine is the easiest way to back up Mac. And the app is created and recommended by Apple. Once you have a timely backup, it’s incredibly easy to restore all or part of your data in case of accidental deletion or a hard drive crash.
So, what kind of data does Time Machine backup? Everything!
Photos, videos, documents, applications, system files, accounts, preferences, messages, you name it. They all can be backed up by Time Machine. You can then restore your data from a Time Machine snapshot. To do so, first open Finder, then Applications, and click on Time Machine to continue.
Be aware that the recovery process can be only be conducted when your Mac can start up normally.
A Step-by-Step Guide to Backing up Mac to an External Hard Drive
Setting Up An External Hard Drive For Machine
Note: the screenshots below are taken based on an older macOS. If your Mac is running Mojave or Catalina, they will look slightly different but the process should be similar.
Step 1: Connect your external hard drive.
Setting Up An External Hard Drive For Macbook Pro
First, use the USB cable (or USB-C cable if you’re on the newest Mac model with Thunderbolt 3 ports) that comes with your external drive to connect that drive to your Mac.
Once the disk icon shows up on your desktop (if it doesn’t, open Finder > Preferences > General, and here make sure you’ve checked “External disks” to let them show on the desktop), move on to Step 2.
Note: if your external drive can’t show up on Mac or macOS hints the drive is not supported, you’ll have to re-format it to a Mac-compatible file system before continuing the following steps.
Step 2: Select the disk for backup.
Now open Time Machine (I tell you how above) and select the disk you want to use. I have partitioned my Seagate drive into two new volumes, “Backup” and “Personal Use”, as you see from the screenshot. I chose “Backup”.
Step 3: Confirm backup (optional).
If you have used another disk for backup before, Time Machine will ask you whether you want to stop backing up to the previous disk and use the new one instead. It’s up to you. I selected “Replace”.
Step 4: Wait until the process is complete.
Now Time Machine will start to backup all your data. The progress bar gives you an estimate of how much time is left before the backup is complete. I found it a bit inaccurate: Initially, it said “About 5 hours remaining”, but it only took two hours to finish. It’s worth noting that the remaining time may vary from case to case depending on the write speed of your external hard drive.
After about an hour and a half, it says only 15 minutes remaining
Step 5: Eject your external drive and unplug it.
When the backup procedure is completed, don’t rush to disconnect your device as this could cause potential disk problems. Instead, go back to the main desktop, locate the volume that your external hard drive represents, right-click and select Eject. Then, you can safely unplug the device and put it in a safe place.
Final Words
Like any other hardware device, an external hard drive will fail sooner or later. It’s best to make a copy of the data on your external drive — as they say, a “backup of your backups”!
One good option is to use cloud storage services like iDrive which I’ve been using and I really like the app because it’s super easy to use, and it also allows me to download Facebook photos automatically. Backblaze and Carbonite are also popular options in the market, though I am yet to give them a try.
I hope you find this tutorial helpful. I can’t emphasize enough the importance of data backup these days, especially when my mid-2012 MacBook hard drive died all of a sudden. I’ve also seen cases where my friend’s computer and hard drive failed. You can imagine their desperation. Without a proper backup, it’s really hard to restore data. Although you could try a third-party data recovery program, chances are they won’t get all your lost data back.
