Samsung Portable SSD T5 not recgonized on Macbook

If you have already done the above fixes previously in old version of MacOS. You do not need to modify anything. Only make sure do not update the software. How to access hardisk if you already have done fixes before Catalina update:

1. Connect hardsisk
2. Open hardisk from (Desktop icon created). Execute the PortableSSD software by clicking the icon present inside the hard drive. Remember not to touch or run the existing installed version on MacBook (even the older version, though, Catalina cannot detect it).
3. When you run first time it will complain of software incompatibility and need to install latest version.(but not complain of software update needed) Here is a trick. You do not update but you install existing old ver. which comes with SSD one. So follow the instruction as it appear on screen .....click ok/ next/ next continue etc. until it give error saying incompatibility and failed to install the software. Repeat this few times. If you already had fixed the SSD software in the previous Mac ver; by third or 4th iteration you will see in the background PortableSSD open up asking to enter password to unlock SSD.
4. Well enter password and access the hard disk from Desktop icon again. This time you should see all your content. Good Luck!

If you're not going to use the drive with a Windows PC, you should format it as APFS instead of ExFAT and dump any of the software that came with it.

Thanks so much for letting us know how you fixed it, _bburr, and thanks to jiggamurf for the detailed description! You saved me!

It might be helpful (to the not-so-computer-savy) that when you open the script, in order to run it you need to hit the "play" button in the top of the window.

And yes, it is the Samsung software. I installed the delivered version and then it said something like "you should update or it might not run on future systems" -- knowing that I will use this on a brandnew Macbook I intend to buy soon, I updated. And that's when the trouble started. The warning should have been "don't update or it might not run on your current system!!!!"

BTW, I have Mojave and the fix worked, in spite of what others had said here (scared me a bit)...

1. Press : Command+Tab
2. Type: terminal (in Search)
3. In the results, choose to open the terminal window. ( Top Hit : black window symbol normally )
4. In Terminal type:

(a) cd <enter>

(b) cd Library/Application\ Support/ PortableSSD <enter> . ( If path did not work press tab after each folde name)

5 . Here you will find CleanupAll.scpt. (Try to run this and see if it work. Though script doesn't run for me :) Hope it work for you)

Good luck! Thank you.

Hi I was facing exactly the same issue. Actually this is because some how the Samsung App do not uninstall when we remove or delete the package unlike other apps of Apple. In my case when I installed the software, I defined my own location for installing package and not the default one. So, I choose and deleted or uninstall the app specifically going to that location. However, that too did not worked. Finally I have to empty the recycle bin, though I do not want to do so. Still it only partly solved the problem. After trying to install it complains that the higher version of package already exists.

Further, I did the following and it fixed:

Follow this. (1) : Reinstall the Latest update back again.

(2) Next follow this steps : Goto this page : https://wordpress.com/read/blogs/4540941/posts/405

It's very long to write all the steps here. so I mentioned in a blog. For anything else related to the same issue you can come back here and read comments by some of the people you will find and is sufficient. Hopefully following those steps you wont have to.

Good Luck

I do not completely agree Daforene, I went through details on Firevault ... it is completely to protect MacBook internal data from external (like internet data breaching ) access.

Read: https://en.m.wikipedia.org/wiki/FileVault

Only probability could be when someone last time encrypt data of external SSD via Firevault, and later Samsung software, PortableSSD, failed to understand or read the disk.

In your case, I guess when you uninstall and reinstall PortableSSD you got the access. Moreover, if you run uninstall from a command line and read the uninstalling messages that appear during uninstallation some of the MacBook preinstalled drivers to access external drive also uninstall (I suspect these are new IOS update / new Samsung app drivers) and removed along with it; and when you reinstall the app these drivers also installed ( old drivers) via Samsung old app which means those ports got reconfigured which give access to Samsung drive.

Further, if you say me you installed the latest version 6.4 or later but it fix than also when you uninstalled last time, the preloaded drivers get removed and Samsung compatible driver would be overwriting the apple iOS drivers.

(though this might not be fixing the problem else by default SSD app update should have worked).

And, May be if I am right these are the executables on which, Samsung has to work on to configure compatibility with latest updated IOS versions and to avoid such issues recurring in future too.

Thanks.

kim.. look on page 1 of this thread . jiggamurf posted some very helpful pics of what to do. when you click on finder you are not looking the box that pops open , you are want to select GO from the from the list at the top of the screen in the background , by the apple symbol in the corner. follow the steps from there. I had the same issue.

Hi! Try inserting "~/Library/Application Support/PortableSSD" instead. Hope it works!

I'm on 10.14.6 Mohave and this fix works. Remember to open Terminal and run the .scpt file using the osascript command like so:

osascript /example/path/to/AppleScript.scpt

Hi! Could you please share how you managed to obtain the software's own clean-up code to fully uninstall the SamsungPortableSSD application? I'm experiencing the same problem with the drive, I'm looking everywhere and can't seem to find it. Thank you :)

Sorry _bbrr I am a total novice. Have the same issue as explained but don't understand what to do. Clicked on Finder and it shows my Favourites and Locations. Where do i click "go" than "go to folder" again please? Try to add to search bar "~/Library/Application/Support/PortableSSD" but that didn't do anything. Please help as really would like to make this drive work. Many thanks

If anybody has iMac mojave trying to uninstall the password encrypted Samsung ssd and need to reinstall older software Have attempted several times your “fix” but no luck.

1) is the Samsung Ssd supposed to be plugged into computer before we start or not plugged in?

2) once we insert your fix above, where does it go?

thank you

Hi,

so happy that you've resolved on your own.

Please check the filesystem: if you formatted the SSD in NTFS format will be compatible for Windows read/write and Mac only read, you need Paragon software to read/write also on your Mac.

Messing with filesystem can be reveal this problem, sometimes.

Best regards

Marco

I've got the same problem as marcfromsalina... I've got no folder called PortableSSD in the "Application Support" folder and I can't find any cleanup script anywhere. So frustrating! I've got 2TB of data I can't get to. Thanks, Samsung.

Lanny how do you do that? I want to reformat the entire drive so I don't need the software, but it doesn't seem possible. If I connect it and don't run software, only a small launch partition (read-only, with the software) is visible. If I unlock with the software, I can format the drive but it doesn't wipe the launch partition.
