- How to Format External Hard Drives on a Mac Running High Sierra OS 10.13 or later
Do you use LaCie or SeaGate Hard Drives on a Mac running High Sierra 10.13 or later? This tip is for you
There is a new setting in High Sierra that allows you to Hide Devices (not a good feature), but it is on by default. Go to View and select Show All Devices:
The fix is really easy, you just have to know it exists.
Open Disk Utility on a Mac:
1. Go to Applications...Utility...Disk Utility or,
2. Open Finder...Click Go...Utilities
In Disk Utility:
1. In View Menu...Check 'Show All Devices' (Cmd+2) or,
2. In Dropdown Menu, View...'Show All Devices'
In Sidebar:
Select Top Entry of Hard Drive you want to Format
Press Erase in Top Center
Name Hard Drive
Mac OS Extended (Journaled)
GUID Partition Map
Erase
Done
Hard Drive should show Green Check and mount on your Desktop
My favorite Hard Drives:

For My Desk: LaCie D2 Thunderbolt 6TB:

Thanks, Mike, a valued helping hand. I've heard so many different version on how to do the same thing you've just shown and it works - I just followed your instructions and here I am now rebuilding Time Machine onto my new drive.
Awesome! Thanks for the kind feedback. Makes my day to hear!! 👊
Thank you!!!! You seem to be the only one on the Internet at this point in time who highlighted the specific issue in High Sierra. Thanks for saving the rest of us big headaches!
I'll take it! Yeah, I really hope Apple addresses this in Mojave. It makes no sense why Apple makes this extra step necessary. I spoke with LaCie months ago and it was driving them crazy because everyone was returning the drives as defects, when there was nothing wrong with them. This video is pretty long for my style so I plan on making a shorter version if you ever need a refresher.
Cheers,
Mike 👊
THANK YOU for saving me the headache of not having noticed the View menu making both the two devices showing for the drive. I was just about to format my new drive the wrong way. I love you man! You Rock! ❤️🎸❗️
Awesome!! 👍👍 So glad it helped you and if you ever have questions or need help with anything, just let me know. 👊
Cheers,
Mike
Thanks so much for the tips! I looked around at other videos and this was exactly what I needed. Keep up the great work Mike! Cheers.
trekbible hey thanks! Much appreciated! 👊👊
Thanks for the info...I was ready to send back cause could not find how to format to OS extended. Your video saved the day!!!
Love hearing that! 👊👊
I greatly appreciate this video to help me - I was trying so many ways to repair my backup drive and now I can use it again. I am not a 'techie' so this was extremely insightful. Thank you!
Patti Randall thank you. It makes my day when I hear things like this. I appreciate it! 👊👊
Thanks! Worked a treat!!
You’re a hero 😂 the stress that hard drive caused me the past days thank you!
That makes my day hearing things like this! Cheers and so glad it helped you. 👊
Worked like a charm. Thanx Mike
Hey John,
Love hearing that! Glad it helped.
Cheers, Mike
Clear and precise! In addition, it works!
Thank you so much for that and glad it helped you! 👍
It works for me, you are the man. Thank you so much!
Awesome! 👊👊
thank you mike, this video helped a lot
Awesome! Glad it helped and thanks for letting me know. Have a great weekend!
Amazing Great Job you helped me:)
Ninja Reacts awesome! Thanks for letting me know. It makes my day to hear comments like that! Cheers, Mike.
AWESOME! Thank you, Mike!
Omar Victor Diop you are welcome!
Thank you so much! I took 2 hard drives back to the store because of this exact issue!
Von Harris you are welcome. I have a feeling a lot of people have this issue and I really can’t understand the reason Apple would put a setting like this as it serves no purpose other than to confuse people or think they have defective hard drives. Glad it helped you and I hope it helps many. Cheers.
i'm a creative type...i know the basics of my 2012 iMac Desktop.....but when it comes to this stuff, I'm like a deer in the headlights.....I have even hired a Best Buy Geek to come to my house, and sit with me, and clean this old sucker up, and see if we can use the WD Windows My Passport 3.0 with my iMac 2.0 USB....I have a HEAD-ACHE!!!!!!!!!!!!!!!
I'm the geek that loves this stuff, but I understand how it can be frustrating when things do not work. BTW, using a WD Drive with USB 3.0 should have no issues with your computer that only has USB 2.0. Let me know if there is anything you need help with or want me to cover in a future tutorial.
Thank you Thank you Thank you!!! You are a life saver! God Bless you!
You are welcome! 👍
Thank you so much, this was awesome help and tip . Have ruined couple hard drives before.
Bummer on ruining the hard drives, but glad this helped you!
Thank you & Happy New Year!
-mike
Thanks alot bud!! Subbed!!!
Awesome Mark! Glad that helped. A real head-scratcher move by Apple and think it messes a lot of people up. If you ever need help with anything or have any tutorial requests, just say the word! Cheers! Mike
Mike Murphy Co thanks alot mate,I'm a wedding videographer and have around 9 hard drives,i went out and got a new one today and since i formated my last ones around a year or so ago everything had changed,luckily i found your channel
THANK YOU.
Thanks a Million TIMES! with a brand new Seagate 4th hardrive shown as unreadable. I watched hours of videos trying to find the solution. Downloaded paragon. Nothing seemed to work especially being a brand new drive . I was about to send it back. Thanks
Nelly Vasquez so glad this helped! I really hope Apple addresses this in a future OS as I think a lot of people have experienced the same issue. Take care and thanks for the feedback!
thank you for this !!
The League welcome!👊
THANK YOU SIR!!!!!!!!! peace from China.
Thank you so much. Thanks to your help, I managed to finally complete
my parents´ backup :)
Rhejcka Awesome! So glad it helped👍
thank you so much! so easy to follow your instructions. So now what is the next step for moving my photos onto the drive?
I really appreciate that. Thanks! Once your hard drive is formatted, it is just a matter of dragging & dropping photos and other media/documents onto the hard drive for storage.
Thanks Man
You're welcome!
You are the man!!

Liaksiej Bandarenka awesome and you are welcome!!
Your great video really helped me!
today i bought LaCie 2TB, and have been a issues)) i saw only 400mb)) i spent many hours in searching "why that?!". after only your video, i got enjoyable answer!! it's great!!!! Thank you, Mike!
I try to write music and this disc needed me for library with elements and files for creativity.
Thanks again for your support, Mike!
Thank you!!! Have you been having any trouble with the mounting in general? All my hard drives were great, zero problem, till I upgraded to High Sierra and now only one of my dozens will even mount! Ugh.
I do not recall having that much trouble with external hard drives mounting (mostly formatting new ones). Are you able to upgrade to Mojave?
If I have a 1TB external SSD (to only store media for video editing) should I format it as APFS + GUID instead of Mac OS Extended journaled + GUID? My Mac is running on High Sierra with an internal SSD formated as APFS. Any help is much appreciated. Great video by the way!
Great question. It's starting to get confusing as Apple is introducing new formatting types.
Short answer: I think you should format as APFS + GUID as it is optimized for SSD drives.
My MacBook Pro internal drive is SSD and was converted to APFS when I upgraded to High Sierra. I do not own any SSD external drives, but after doing some research, I would format at APFS + GUID.
Considerations:
APFS is not backward-compatible so your hard drive will not mount on older machines not running OS High Sierra or later.
Hope that helps,
Mike
THANK YOUUUUUU
You are most welcome!! 👊👍
LIFE SAVER THANKS
You're welcome. Glad it helped! Cheers 👊
Mike Murphy Co true this is because I had to install macOS on my new SSD and I was worried that I couldn’t find this Volume Scheme
Rishab Rammohan yeah, it’s a bad move on Apple to make it unnecessarily confusing for no reason. Glad you got it figured out before you had a mess on your hands.
Mike Murphy Co very true
You ROCK!!!
Veronica Puleo 👍👍😎
awesome mike i have imac 2011 model what do you reccomend to use of a external hardrive to use just to add my photos and vids make more room on imac ?
Hi Tracey,
My favorite external hard drives are made by LaCie, but I also think Western Digital are affordable and reliable if you just need a drive for Time Machine backups or to store files & media.
Here is a 4TB Western Digital Drive for only $99 that would work fine with your iMac:

Let me know if you need any more help with anything.
Best,

Thanks :-)
D CB You’re welcome!
Thanks
David Fagan you are welcome! 👊
prior to updating to high sierra my 2tb lacie was working fine. After the update my MacBook pro isn't reading it anymore. Any ideas on what it can be? I plug in my other lacie hard drive and it reads that one. It was reading it fine before the update
I would first power down your computer all the way and restart. Plug in drive.
Plug in drive directly to computer and not using a hub. Try different USB Ports.
Test the drive on another computer and see if it will mount another computer.
Hi Mike,
My Seagate worked fine before High Sierra update. What are my options because I cannot reformat my external drive, everything I have is on this external drive that use to read/write/copy. Please help
Hi Andrew, I need to fully understand what is happening as it sounds like you are having trouble mounting your external drive and accessing the data on it. You do not want to format the drive at this point as you will erase everything once you format.
Tell me exactly what is happening. When you plug in your Seagate drive, it does not show up? Have you opened Disk Utility? Does it show up on the sidebar (left side). Do you see the option to Mount? Have you tried turning off computer and re-booting?
You can try starting your Mac in Safe Mode and see if it mounts okay. If it does, it usually indicates there is some type of software conflict. Turn off computer. Tap the power button and press the Spacebar until the login screen appears. Safe mode takes awhile to boot and may seem slow. It is really just troubleshooting. You can exit safe mode by restarting.
Let me know more details and I can help. Do you have access to another computer where you can plug it in and transfer data and then re-format drive?
So...some new things have happened since the 2019-004 update SNAFU. I noted that my SSD was not being recognized under the system report and TRIM support as a solid state drive. I had no problem updating that for my older white macbook running El Capitan but it was a different story for High Sierra when all sorts of problems occurred after I did this update including the "fix" which did not totally resolve my kernel panics. It took me ages to get restarted and a lot of luck. Now, I'm between a rock and a hard place: do I try and fix this in Terminal first, or try to create a Time Machine Backup on an SSD that does not show as a supported SSD user system report?
I hesitate to give you advice without learning more and being able to see exactly what you have going on, but have you tried contacting Apple Support to get help?
@@MikeMurphyCo Yes, thanks--they told me everything I'd done already was the best they could advise me (that includes all the different command and restore options, resets, etc.etc.). The so-called Apple store genius told me he thought my graphics cards was the problem, (and told me to buy a new computer), even though it passed all their tests and the ones we can do ourselves (which I've run repeatedly). I get a bright blue screen with fine vertical white lines in it when I try command + R most of the time, or other recovery commands. I just got it started again today after 2 days of trying everything including different internal and external hard drives, and my CCC backup drive (which used to work but stopped working). If the OSX Mac Utility box opens with the 4 options then I can restore H. Sierra and it works fine until the next kernel panic (I've disabled sleep mode etc. under energy saver which helps a little but other things have caused it to freeze up as well. One time it was when I tried to open Time Machine and another time when I tried opening an avi file or Apple Photos. My brother started having problems too with his Mac mini (also on High Sierra) after the security update and he's still trying to resolve his as well.
Bill Wilkat sounds frustrating, but not entirely sure how to advise you on this one. You are unable to upgrade the OS to Mojave?
@@MikeMurphyCo Not upgradable beyond High Sierra.
@@MikeMurphyCo Yes, but not helpful in the end. I got started using this instruction: ruclips.net/video/iLft4N54zvU/видео.html Hope it's all good but I understand I can't do updates or I'll need to do this all over again.
why did you choose the GUID partition? how's that different from the master one?
Hi Usman...I do not know all of the technical differences between the two exactly, but I do know GUID is a more modern standard and for Intel Macs and is required for all drives over 2 TB. The other advantage of GUID over Master is you can have more than 4 partitions. Hope that helps and thanks for the comment...Mike
Thanks

what to do if the disk doesn't show up even after checking the show all option.
the external drive is connected but it does not show up on the finder or disk utility or terminal.
but works fine on windows.
any solution?
I can help you troubleshoot.
The first thing I would try is to shut down everything. Plug in the drive (use a different port if possible) and then turn computer back on. Open Disk Utility and see if it is anywhere on the left side.
Does your external drive need to work on both PC and Mac? If not, can you format the drive on Windows machine to Mac OS Extended (Journaled) or something like MS-DOS (Fat) or exFAT and then plug it into Mac and re-format it in Disk utility to Mac OS Extended (Journaled)
Let me know how I can further help.
the external drive is connected but it does not show up on the finder or disk utility or terminal. but works fine on windows. any solution? I'm ready to format the drive to APFS if the drive shows up. By the Way the Mac's hard drive is on APFS and the system runs high Sierra 10.13.3 (17D102)
and thank you for replying
I tried what you suggested no use
the system detects thumb drives but not the WD external hard disk 2TB
and the system is late October 2016 MacBook Pro
A lot of WD drives come formatted with NTFS & Macs need +HFS (pre-High Sierra) or APFS (10.13 or later). Since you have access to a Windows machine can you format the entire drive or partition by adding a new volume and formatting for +HFS or whatever the PC will allow you to do. It may be MS-DOS (FAT) or exFAT. I have not formatted a drive on Windows for some time.
Also, If you are using a USB hub I would plug it into computer directly. 👍
any suggestions on what software to use for formatting the external drive to HFS or APFS?
I'm confused on selecting the correct one!
Help please!
I do exactly what you did, but it shows:
Erase process has failed. Click Done to continue...
Unmounting disk
Couldn’t open device.
Operation failed…
What should I do?
TIA!
Hi Eliel...I can help you but I need to know some details.
Are you on a Mac using High Sierra 10.13.5?
What kind of external hard drive are you trying to format?
Is the external hard drive new or have you used it before?
When you plug in the hard drive does it show up on your desktop?
In Disk Utility, you selected the top title and chose Erase?
Format: Mac OS Journal (Extended)
Scheme: GUID Partition Map
Fill me in with details and I can troubleshoot for you.
Thanks,
Mike
Hello Mike, I have the same issue as the person who added the comment I'm using high sierra 10.13.4
I'm trying to mount a WD 2TB external hard drive it has been used before but everything was clean after it was given to me, it doesn't show on my desktop and yes i clicked erase its under that format and scheme
please help!
Itzel Mercado Hi there. First off: Are you running Parallels for Mac by any chance so you can also run Microsoft Windows on your Mac? If no, just ignore that. I’m just ruling stuff out.
I’m going to go through the steps to help you format your hard drive using High Sierra, but before you do so, turn off your Mac completely. Unplug everything from the computer ( take out power cable and unplug all USB/Lightning cables, etc). Plug them all back in after at least 30 seconds and turn computer back on.
1. Make sure external drive is plugged into your computer and not a hub ( unless you have new MBPro with no ports)
2. Open Disk Utility
3. In the View Menu Select Alll Volumes
4. In the left sidebar, locate the external drive and click on the top volume
5. Press Erase
6. Select AFPS or Mac OS Extended (Journaled)
7.For Schema, Select GUID option
8 Press Ok to erase.
9 wait until it says done with green ✅
10. Look on desktop for the drive.
Let me know if it works for you. It should if the hard drive is okay.
Best,
Mike
I tried and got an error that said could not write to last block of devise
Try powering down your computer and wait 30 seconds and then power back on and try agin using the instructions from tutorial. 🍀
Ok I’ll try again and let you know thanks
You wouldnt happen to know how to install mac os high sierra on my book. I could install mac os sierra but not high sierra. I formatted the disc in the boot up menu but still no luck
Hi Dee. I'm not sure I know what you mean by installing High Sierra on your book. If you have a Mac that is newer than 2010 it should install either Sierrra or High Sierra. Are you getting errors when trying to install High Sierra?
The external hard drive is called my book. I actually just got off the phone with apple and they said with the new format they made where people couldnt have your external hard drive as a start up. Might be a way and they didnt want to tell me but i havent heard anyone use an external drive as a boot drive for high sierra. I still use it for regular sierra though. My internal drive doesnt work anymore
Dee 4 ah. Now I understand. Yes, the new APFS seems to be causing incompatibility issues and errors for many people.
I had not heard about the issue with High Sierra as a bootable startup drive but good to know. Thanks. Looks like there are some third party workarounds for formatting externals, but maybe there will be a future fix. Who knows with Apple lately. Good luck and sorry I could not be of much help. Best-mike.

i finally able to make a windows to go on my samsung t5
mine does not do it. it says smart status not supported.
What are the exact steps you are taking? What type of hard drive are you formatting?
@@MikeMurphyCo so my dad says he formated it on windows before and it is a hard drive for mac called my passport. he said you need to add some software so it will run on mac. if you can redirect me to a video with that, explains that it will be appreciated
@@Namibal204 You do not need to install the WD Smart software. You just need to format as Mac OS Extended (journaled). Follow the exact steps in the tutorial and it should work. 👍
@@MikeMurphyCo it wont. i followed all the steps.
@@Namibal204 Eject Drive. Power down computer. Unplug it. Change the cable if you have another that is similar. Make sure it is not connect to a hub and directly to computer. Turn computer back on. Plug in and try again.
