It is not a Catalina thing, I have a Seagate Backup Plus Hub drive that was formatted as exFAT on a windows computer and will not mount on a mac and gives me the exact same error as this thread. And it started to happen on my mac before Catalina and also was an issue on another mac with a mac os Sierra.

Windows can format the drive using different block sizes some of which macOS does not recognize. Backup any files on this drive and use the Mac’s Disk Utility to erase the drive as GUID partition and ExFAT. You need to erase the physical drive so you may need to click on «View» within Disk Utility and select «Show all devices» before the physical drive appears in the left pane of Disk Utility. This should allow the drive to be used on both Windows & Mac.

When you say Seagate Software, are you referring to the Paragon or something else?

I’ve never used the Seagate external drives or their proprietary software, so I am not sure what is included. Did you run a Seagate app which was included on or with the drive? If so uninstall it using the included uninstaller or by following Seagate’s instructions. I know Paragon software is sometimes included with the Seagate software to allow writing to NTFS volumes.

If you downloaded the Paragon software separately, then yes uninstall it according to the developer’s instructions since it is not needed on a Mac unless you need to write to an NTFS volume or access a Linux file system.

Yes I was referring to paragon software. Here’s what I know:

1. I have a seagate drive I’ve used for a few years now. When I bought it, it would only mount as read-only on my Mac. I installed the Paragon software and it worked fine after that.
2. I have backed up 100+ GB of data to that drive over those years
3. I updated to Catalina. The seagate drive would no longer work, mounting as read-only. I updated the Paragon software and the drive worked fine. Just as before, I don’t have to do anything, as it mounts automatically when I plug it into my mac.

It continues to work fine now. I understand from other posts that this won’t work for everyone, but I can’t comment on those posts. I’m just passing on what I did. I don’t worry about disk formats or Mac vs. PC, I’m just a guy using a disk drive for backups.

Unless you are using an external drive for access with both Mac & Windows you should always use macOS Disk Utility to erase the drive as GUID partition and MacOS Extended (Journaled) so that only macOS is managing the drive using a native macOS file system. If a drive needs to be shared between Mac & Windows, then erasing the drive as ExFAT on a Mac using Disk Utility is an acceptable alternative since both macOS & Windows support read+write ExFAT file system (it must be erased on a Mac since Windows may format ExFAT with options currently incompatible with macOS).

Third party software is not needed to use an external drive on a Mac unless you want to use the built-in hardware encryption feature found on some external SSD drives. Third party software usually ends up causing issues at some point, but especially during system updates or upgrades. Plus access to the drive may become lost if the proprietary third party software is no longer supported.

Unfortunately this is a Windows only world when it comes to third party hardware so hardware manufacturers default everything to work with a Windows system which means many external drives are shipped using the Windows NTFS file system. It is always best to use the operating system’s built-in native file systems whenever possible to reduce the risk of problems and compatibility issues.

Just something to consider and I hope this information may help others.

Yep I agree its lousy advice. I guess some people should think before offering any advice and consider whether their advice is actually helpful.

I have read the whole thread and now concluded this is on Apple, not Seagate.

I bought the Seagate drive before Catalina. After installing the Paragon driver, from Seagate, everything worked. When I upgraded to Catalina, I needed to install a newer version (64-bit). Then it continued to work. A week ago, it stopped working on one of my computers. But it continued to work on the other. Before I triage, the other computer auto-upgraded itself to a newer Catalina. Now both computers stopped working for the drive.

I uninstalled Seagate’s paragon driver, the disk mounts but read-only. I reinstalled the previously working driver (same version) and the problem reproduced.

I guess Apple may claim the Paragon driver is now incompatible with one of the later Catalina patches and I will accept that. The point is still that Apple’s patch broke the driver, not the other way around.

I now have a 5TB drive that is basically useless.

Guess Seagate, Paragon, or Apple need to do something.

And so many other users in this thread have blasted me for recommending people not to use the proprietary software which ships with external drives! Seems I might know what I’m talking about!

You cannot expect Apple to make sure every piece of third party software works in macOS. It is up to the hardware manufacturers to update their third party software. It is the way it has ALWAYS been. It is the same for Windows & Linux systems as well. If you have an issue with a third party app provided by the drive manufacturer, then contact the manufacturer of your external drive for support and to complain about not having a timely software update to the app.

You do have options here. You can report the issue to Seagate and wait for an update to their app. Or you can transfer everything from the now read-only external drive to another drive or computer. Then erase the external drive using Disk Utility. Erase the drive as GUID partition and MacOS Extended (Journaled) if you will only be using it on Macs. Or if you will be using the drive with Windows as well, then erase it as GUID partition and exFAT using Disk Utility. If you erase it as exFAT on Windows, then macOS may not be able to read the drive. Once the external drive has been erased using Disk Utility, then you can transfer all the files back to the external drive.

stay friendly, be happy. we are not in the 1980’s anymore where any manufacturer made his own thing and almost nothing did fit well together. I personally refuse to use third party tools only to access well known, simple devices. to buy any harddrive in the next shop and use it without trouble should be no magic anymore today. not even when using an apple computer …

I have been an OS developers for decades and, in general, agree with you that the manufacturer must ultimately bear the responsibility to make things work.

In this case, however, it was working and got broken by a minor OS patch. Therefore, the patch failed the regression tests against the vendors.

Nearly all OS vendors maintain a large lab and developed a comprehensive regression test suite to prevent things like this from happening. Simply, what was working should continue so. Either Apple did not find such failure, didn’t warn Seagate on this failure, or expect a different relationship than what us customers expect. Probably Apple expects Seagate to test against all patches on its own and remedy any issue. From what I read from Seagate’s website, they appeared completely oblivious to this failure.

Apple must manage its ecosystem as a platform vendor. Your reply basically stated that Apple bears no responsibility. It’s either Seagate’s or customer’s problem. That attitude is really disappointing.

The industry is saying that «Apple is becoming Microsoft faster than Microsoft becoming Apple.» Remember that consumers have choices. Being arrogant will hurt you.

Just search this error message on the internet and count how many customers encountered the same problem. This is not isolated to Seagate. Catalina is not reliable. Fix it.

My 5 TB external harddrive is powered via external power supply and the Mac can’t use it, so I assume Mac and harddvie are just not working together for an unknown reason.

I have 2 external hard drives that are formatted the same. They both work when connected to my windows computer. The Samsung 1tb hd works when I connect to my Mac and it is powered by a wall plug. The seagate 6tb hd shows up but won’t mount, I can verify it using paragon software and is powered by the usb cable. I’ve tried using paragon software(old version/updated version), it still didn’t work.

That is one of the dangers of using a non-native macOS file system and relying on third party software to manage the drive. You may need to contact Seagate for support.

What file system is used on your 6TB drive? macOS should be able to mount an NTFS file system in read-only mode. If the drive is formatted as exFAT, then the exFAT format may be using block sizes which macOS cannot understand. To use an exFAT drive with both Mac & Windows you need to format the drive on the Mac using Disk Utility.

I have both hard drives full so I can’t just reformat the seagate. Is there any chance that it could be because the hard drive isn’t getting enough power from the Mac book? Or does the seagate hd and Mac just not play nice together?

Try using a powered USB3 hub with UASP support to connect the hard drive. This may help provide any extra power plus it will act as a buffer between the devices. Does the 6TB drive come with its own power supply or special double USB cable/dongle? Years ago I did encounter a drive enclosure which would not work on a Mac, so there is always a possibility of hardware incompatibility, but by using third party software the situation becomes more complicated. I think a 6TB drive will need extra power to work either with a double USB connector or its own power adapter.

Have you disconnected all other external devices from your Mac when trying to access the 6TB drive? Is your laptop using its power adapter?

Have you tried booting into Safe Mode to see if the 6TB drive can be mounted as read-only if it is formatted as NTFS?

Has this 6TB drive ever worked on this Mac? Do you see the drive (or the drive’s controller) show up under the USB section of the Apple System Profiler? You can access this by Option-clicking on the Apple menu and selecting the first option (System Information?).

Maybe your drive is physically failing. You may be able to check the health of the external hard drive on Windows by using GSmartControl (portable app available requiring no installation). GSmartControl also has a method to run a drive’s internal self diagnostics. There is no guarantee this information can be accessed since some external drive’s USB controllers block the necessary communication. Maybe your Seagate software on Windows can access this information or even test the physical drive. Feel free to post the GSmartControl report for the drive here using the «Additional Text» icon which looks like a piece of paper.

If the external drives are not backup drives, then I hope you have backup copies of all the data stored on your external drives.

I think we have already clarified that this issue is not related to third party tools and also appears when you are not using them. I haven’t expected there to be that much guys defending Apple at all cost by lacking any helpful information why in nearly 2020 a harddrive bought in the next store should not be able to be used without any hassle with any modern operating system.

I am far from an Apple fan. I’ve been strongly opposed to the direction Apple has been going for years now and yes Apple does make some pretty stupid decisions. I personally do not purchase Apple’s computers, but am forced to use them for work. Apple is really a closed system where you do it Apple’s way or you will experience difficulties. Same thing if you do something which Apple did expect.

If you search these forums you will see so many threads where updating or removing third party drive management software solved so many of the users’ external hard drive problems.

Yes there can be hardware incompatibilities, but it is hard to identify the hardware issues when some people are unable to erase the drive to test without the third party software being involved. Some of the users posting here with problems may need to contact a local Apple hardware expert to physically examine their computer & drives to see what the source of their individual problem is. You also never get the complete story or system setup from people posting here so we are always working with incomplete information and many unknowns so there could be other factors involved such as security or AV software, etc. Like I said in my last post a 5TB+ drive may require extra power.

Many hardware vendors only pay lip service to macOS compatibility because unfortunately we live in a Windows centric world which is why most of these drives come pre-formatted for Windows with NTFS. Like Linux users Mac users need to research products and carefully choose & configure those products. Mac users do need to understand the hardware more than their Windows counterparts because a Mac user usually needs to do more to make hardware work properly. Mac users do have an option of purchasing guaranteed & tested products from an Apple friendly vendor such as OWC. If Mac users purchase off the shelf items at a regular store, then the Mac user will need to deal with possible incompatibilities. You know nothing of compatibility issues until you try to find Linux compatible hardware or Linux compatible firmware updaters. While Mac users are second class citizens in the tech world, Linux users are treated like the plague by hardware manufacturers. I agree it would be so nice if everyone would agree to standards and then properly implement those standards, but everyone including Apple takes shortcuts.

I was lucky and able to store my backup somewehre else so I connected my 5 TB harddrive with the Mac and made it ExFAT GUID. The harddrive itself is brand new and working okay on both Windows and Mac this way. Nethertheless I remember «strange» things like going into the next shop and find «special» hardware like harddrives with a MacOS compatible sign attached to. For those who are not too familar with re-formatting/partitioning that thing themself. ^^
