Cannot write on "FAT32/MacOS extended" usb flash drives

Question

Cannot write on "FAT32/MacOS extended" usb flash drives

Hi...

I have 2 MBPs:

MBP1 - 13", Early 2011 with High Sierra onboard (+ Paragon NTFS for Mac oS X installed many ears ago)

MBP2 - 13", Early 2015 with Mojave onboard.

I can't write any files on "FAT32/MacOS extended" usb flash drives on MBP2

BUT

I can write files on the same exact "FAT32/MacOS extended" usb flash drives on MBP1.

How to fix an issue on MBP2?
Can it be the cause that I'm able to write files on FAT32 usb drives due to installed Paragon NTFS on MBP1? Or it's not related?

Thank You!

Macbook (2015 or later)

Hi

"No such thing as "FAT32/MacOS extended" drives unless you are saying the flash drive is partitioned."

I meant two usb flash drives: one with FAT32 and the second one with MacOS extended file systems. Sorry for confusing.

Yes, correct. It were formatted in Disk Utility some time ago...

And seems I "groped" the reason...seems that my second MPB2 has corporate USB restrictions...found it in profiles...talking to my IT help service.

Hi...

USB sticks are Kingston HyperX Savage 64GB and Kingston 64GB DataTraveler R3.0 - not very old.

I bet on corporate USB restrictions on MBP2....there is a such user profile which can't be deleted...I'm trying to check whether it can be modified a bit at least...

Nope - just can't to transfer any files on these drives...

In "get info -> Sharing & Permissions" section I see You can only read.

Don't know what that's about. I tested a couple of flash drives formatted as FAT32 and I have custom access.

It is a permissions issue, the dialog box is clear on that much at least:

This is from the bottom of the picture you posted.

No such thing as "FAT32/MacOS extended" drives unless you are saying the flash drive is partitioned. NTFS has nothing to do with FAT32 or MacOS Extended.

No problem. There doesn't seem to be a good reason why you can't write to the drives on the MBP2 other than a permissions problem. Do you get an error message?

Were the drives in question formatted with Disk Utility?

According to the OP, yes…

Is this a very old stick? USB 2 or lower?

PM, in SystemInformation (in Utilities) you can see the differences of the USB in MBP2 and MBP1.
