Seagate Backup Plus won't show up anymore

I have a 1TB Seagate Backup Plus for Mac Portable Drive. I bought less than a year ago. It had been working great. Until recently. Since the last week or so, when I plug it in my Macbook Pro (10.9.5), the external drive lights up but it doesn't show up on my desktop. I checked Disk Utility as well. Nothing there either. It simply doesn't read it.
I have had OSX Mavericks installed for quite a while now. Recently I tried to update it to Yosemite, and it looked like it worked, but apparently not. My "About this Mac" still shows 10.9.5. Maybe it just updated to a higher version of Mavericks. I am wondering if the OSX might have something to do with my ext. drive not getting read. I already tried it on a different mac with a much older version OSX. Doesn't show up there either.
Of course, I also checked that the problem is not with my connection chord. I tried a different chord with my drive, but no changes. I also tried it on a friend's computer using his chord (which definitely works), but it doesnt show up on his computer either.
Any thoughts what the problem and the fix might be? I have important data on this hard drive, and have also backed up my Timeline on it. I cannot afford to lose my data, in any circumstances. Please help.
Thanks

Take out the HDD from the enclosure and install it in a different one. It could be that the internal SATA connection board is faulty.
Do not dismiss the possibility that the HDD has died.
Ciao.

Seagate backup plus won't read

So my seagate backup plus external hard drive won't be read by my Mac.
It's functional, I can hear it running fine when I plug it into my USB port but the only place my mac show's it's connected is in the system profiler, no where else.
I can't find it in the Finder or the Disk Utility.
Any ideas of how to get it to read?
I have important documents on it.

If the HDD is formatted NTFS, then it suggests that there is a problem with the PC. Check with the manufacturer.
Ciao.

What do I need to do to be able to read and write files to a Seagate Backup Plus Slim Portable Drive on BOTH a Mac and a PC? I downloaded "Paragon NTFS for Mac" onto my Mac, so now I can write to the drive, but when I plug it into a PC it won't work.

Seagate Backup Plus 3 HFS formatted drive when plugged in to new Airport Extreme causes it to shut off and shows constant amber light. Please help.

I just purchased a new 3tb Seagate Backup Plus 3 to attach to my new Airport Extreme. When I plug the Seagate's USB in to the AE, the drive starts spinning, clicks and then the AE light turns amber and the wifi connection is lost. After I unplug the HDD the signal comes back and the AE light turns green. I have even tried using 3 partitions on the drive to see if that would work. I have a 1tb portable drive that has worked on the AE but this new drive doesn't. I have formatted both drives with Macdrive 9 pro and only the portable drive has worked. I've tried everything I could find on the internet to resolve this. I hope someone out there can help.

When it blinks amber, use the airport utility to peek at the status to see what error it's telling you. I'm guessing you MAY need to use a powered hub...

My external hard drive (Seagate backup plus) has stopped working on my macbook 10.8.5

I've been using Seagate Backup Plus for a year now and suddenly it has stopped working on my Macbook Pro (mountain lion 10.8.5). When I plug it in, it lights up and I can hear it running, but it won't show on my macbook. I've checked on Disk Utility but it won't recognise the hard drive. I also tried going on Terminal to see if my hard drive is listed by putting "diskutil list", and it's not. I also make sure that external hard drives are visible on Finder. Since my hard drive is on NTFS format, I tried uninstalling and reinstalling the NTFS drive, and still it won't work.
My hard drive is working perfectly on other devices and PCs so I'm sure the problem is on my macbook. Usb ports of my macbook are also working perfectly.
Please help. Thanks.

Open Disk Utility (Applications>Utilities folder) and format the disk as "Mac OS Extended (Journaled)" with a single GUID partition. Your Mac should see the drive and you should be able to use if for backups, storage, etc.

How do I reformat my External Hard Drive (Seagate Backup Plus).

Hello everyone. How do I reformat my External Hard Drive (Seagate Backup Plus Portable Device). I accidentally clicked to use it with Time Machine and my hard drive is of little use now. When I open my hard drive, it just shows 'backup', the same thing when I open it with Windows. Thinking of reformatting it back to be used to Mac and Windows. And not use it again with Time Machine. New to Apple, appreciate the help

Hello,
"Thinking of reformatting it back to be used to Mac and Windows. And not use it again with Time Machine"
If you want to format the External drive as universally compatible, your best bet is to format it as exFAT. Note that reformatting the drive erases all contents of the drive.
1) Open Disk Utility located in /Applications/Utilities/ (or simply type it in spotlight and the application will show up)
2) Select the external Hard drive
3) Click the 'erase' tab.
4) Under format: select exFAT
5) Click "Erase" in the lower right hand corner to reformat the drive.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Seagate Backup Plus

I just installed Seagate Backup Plus on my Macbook Pro and am not seeing a user manual anywhere. It installed just fine, saved all of my documents etc. - took four hours. Now I want to make sure I don't lose the data on my computer.
Question - if I delete files on my computer, and I have the external drive set a Time Machine - when I plug the drive into my computer, will the files I deleted in my computer then be deleted on the drive? Because it is saving the changes from my computer - it will also delete the files on the drive?????
Also, I'm trying to see the files in the drive - they are there - it is showing in the number of GB used. The instructions etc. say go to the Dashboard - where is the dashboard? I cannot find it anywhere! I am not seeing my files in the drive.

No such thing as 'wasting money on a backup'
Ideally you need 2 external HD anyway, ....backup and archived important data.
* Also a lot of people use carbon copy cloner or (my fave) SuperDuper to make an exact copy of the HD that is bootable. So if the HD crashes, 15 mins you throw in the clone and your back and running.
external storage, quality too, is absurdly cheap right now.
Heres superslim external HD.
see this: only 7mm thick
$50

Considering how many YEARS some people work on their data, and pics of dead loved once you CANNOT replace, .....its not only important, its IMPERATIVE people have at the very least 2 copies of that data.
What cost for priceless data when it comes down to a $65 hard drive???

I just bought and backed up my computer and time machine with a "Seagate BackUp Plus for Mac". Now my time machine is empty. Panicked. can anyone help?

I just bought and backed up my computer and time machine with a "Seagate BackUp Plus for Mac". Now my time machine is empty. Panicked. can anyone help?

Lets start over...
Please restart the network.. shut down everything..
Restart in order.. modem.. router.. if different to TC.. or TC.. client devices.. wait 2min between each startup.
If the TC does not show up on the computer, in finder.. then we need more info.. what OS are you running?
Does the TC show up in Airport utility? Are you running wireless or ethernet?
If you still have issues.. plug the TC directly into the computer by ethernet.
Do a full factory reset of the TC.. and see if it now shows up.
Please tell us exactly what model TC it is and how old.. the A1xxx model number from the base will help if you don't know.
You take a screen shot of the TC opened in finder.
eg..
My TC is named Tardis4.. click on it.. and then open the data folder.. on this one called Tardisdata.
Then take a screen shot of it so we can see what the problem is.. screenshot.. with area selection.. control + shift + 4 .. the picture goes into the desktop.. and then you click the picture icon in the posting web page controls and select the picture.

How can I transfer files from one external HD (WD My Passport) to another external HD (Seagate Backup Plus)? WD drive was improperly ejected and Finder no longer recognizes it. Tried fixing with Disk Utility but failed.

How can I transfer files from one external HD (WD My Passport 2T) to another external HD (Seagate Backup Plus 2T)? WD drive was improperly ejected (although we did tell it to eject) and now Finder no longer recognizes it. Using MacBook Pro and I just upgraded to Yosemite before this happened. Was told at Apple Store to use Disk Utility to repartition, but it failed. It says to backup files and restore. But how do I backup files? Or would appreciate any other suggestions to repair drive.

You may drag & drop between external hds.
Should you run into trouble.
Take the exernal drive appart. Take out the harddrive. Try reading the data via a usb adapter. Put a household finan on the hd.

Seagate Backup Plus Slim External USB 3 Hard Drive Not Working with Mac Pro

Hi, I have just purchased a brand new Mac Pro. I have three 2 TB Seagate Backup Plus Slim External USB 3 hard drives that just don't jive with the new Mac Pro's. When the drive is connected, I cannot access the drive, read/write or even format. Finder completely locks up and the drive cannot even be force ejected. When I try to format, Disk Utility either spits out an error that the drive cannot be read, or simply locks up. This happens regardless of the OS on the Mac Pro. I am currently running 10.10.2
I have ruled out an issues with the drives, as I have tested all of them on a variety of systems and OS's, including Power Mac, Mac Book Pro, PC, OS 10.7, 10.8, 10.9 as well as on Windows. I have tried formatting in every file system including Mac OS Extended, Mac OS Extended (Journaled), NTFS and exFAT. ALL other systems have no issues with the drives. Apple has replaced my Mac Pro with a brand new one and the drives still behave the same way. Furthermore, I have tested the drives on three other Mac Pro's at work and they all reject the drives. So, on their own, there is nothing wrong with the Mac Pro, or the drives. However, the configuration of them together is wreaking havoc.
I have contacted Seagate, and this was their response:
The most recent version of the Backup Plus drives use the USB Attached SCSI (UAS) standard to increase transfer rates. It's possible that the drivers being used currently on your Mac Pro are having issues using this feature with the standard USB 3.0 drivers installed. I would recommend contacting Apple to check for any driver updates or see if they any suggestions for issues involving drives using UAS.
I have also started a case with Apple Support (Case # 755934373) and am waiting to hear back regarding Seagate's response. I've spent DAYS trying to troubleshoot this and am now at a complete loss. If anyone has any ideas, I'm all ears (or eyes in this case).
Thanks!

Hi danielsh6,
I recently bought the new Lacie Thunderbolt 2 D2 3TB and I had the same problem as you, i have a macbook pro early 2011, those support thunderbolt but many times there is a bug that doesn't let you connect any thunderbolt drives to your computer. The solution I found was installing this update:
Thunderbolt Firmware Update v1.0
Before doing this I would recommend you updating to mountain lion (not yosemite yet as there is still some glitches and more on preview's macbook pro's).
Hope this helped!

Okay so I have a Seagate Backup Plus Drive External Hard Drive and I'm trying to get it to backup Applications and stuff on the dock such as iPhoto, and Photo Booth.

It's one of these External Hard Drives. I go to the Finder folder and go to the "Seagate Backup Plus Drive" to see what's in there and what I assume is that backups but the only thing that seems to be in there is folders from everything that is Desktop and a few Documents. The Applications folder seems to be empty and there are no folders for Photo Booth or iPhoto. Everything from GarageBand and iTunes seems to have been backed up according to the Seagate Backup folder when it is plugged in and opened. How do I get this thing to backup everything from Photo Booth and iPhoto? And by the way, I can't seem to access Time Machine the way you get it to where you can go back in time and see all of your stuff from previous dates. I don't know if this is important or a crucial part but I seem to not be able to access the actual time Machine Layout.

Simple on that one - Download Carbon Copy and follow the steps below:
if you have access to an external USB enclosure use it, or you can buy one for $10...
install your new ssd in the usb enclosure - connect to your macbook...
open disk utility and format/erase your ssd - mac os extended journaled.
open carbon copy - clone your drive with it - source (your old drive) + destination (your ssd).
once the clone is done, turn your macbook off - take old hard drive out - install new ssd in....
turn your macbook on - if boot time is more than 40 secs to desktop - go to system preferences - startup disk and select your new ssd as the startup disk - restart your macbook - should be about 14 sec boot time now.
install your old hard drive in your usb external enclosure and use it as a backup drive.
good luck

I am using a Seagate backup plus portable drive on my iMac 7 with OSX 10.9.2. At startup up I always get a popup window stating "The disk you inserted is not readable by this computer. I click ignore and everything seems OK. Is it?

I am using a Seagate backup plus portable drive as my time machine backup on my iMac 7 with OSX 10.9.2 Mavericks. At startup I always get popup window stating "The disk you inserted is not readable by this computer..? I click ignore and everything seems to be OK.

If you installed the Seagate software, remove it according to the manufacturer's instructions.

Options for Seagate Backup Plus for Mac/Windows

I have a new Mac-mini (my first Mac since my original Mac 128), and just got a 3TB Seagate Backup Plus. It's so new, I haven't even read up on Time Macine though I assume that's the way to go.
I originally had in mind partitioning the Seagate with one HFS+ for the Mac and one NTFS for my Windows laptop (Win7) and old Windows desktop (XP). The latter is mainly for storing files in a place where it will be convenient to use them on the Mac. But with all the threads about partition and other errors, I'm wondering if that's not so wise.
The obvious alternatives are leave the drive as NTFS and find something other than Time Machine for backing up the Mac - or format it as HFS+, use TM to backup the Mac, and install HFS+ drivers at least on my laptop.
I usually like to try and research these sorts of questions directly, but with the learning curve moving to the Mac, and all sorts of other things, it would take me to next year to find my ideal solution. So for now, I'm just looking for suggestions on a backup strategy for the Mac that would, in addition to backups, leave space for manually archiving Mac files as well as exploiting the spare space on the external drive for some Windows purposes. (Not much videos, mostly photos, finances, and eventually my main reason for getting the Mac, ios development.)
Thanks for any suggestions.

Time machine, seagate backup plus

Hi ive bought a seagat backup plus external hard drive. Ive been using it to transfer files from a pc to my new mac. When i originally used it for the first time, i think it asked me if i was using it between both windows and mac formats so i said yes, and this has worked seamlesly.
Now all my files are on the mac, i want to use it for a time machine back up. Upon trying this it failed because it is not in the correct format i think.
So here is a couple of questions....
1- How do i give it the correct format?
2- Some of my family still use the windows pc, and i would have liked to have still been able to use the hard drive across both formats. So if i format for Time machine, will this not then be possible?
Thanks.

Sorry, an external that is used only for Time Machine.
see > Mac Basics: Time Machine backs up your Mac
Because sooner than later, Time Machine will use all the space on the drive.

Seagate Backup Plus won't show up anymore
