arduous drive – Why does my exFAT exterior disk present errors on Home windows and corrupt PDF information after formatting on macOS?

I partitioned an exterior disk as exFAT on my Mac utilizing diskutil and the next instructions:

1. diskutil listing
2. diskutil unmountDisk drive disk2
3. sudo dd if=/dev/zero of=/dev/disk2 bs=1024 rely=1024
4. diskutil partitionDisk disk2 GPT exFAT "Home windows Partition" 0g

After partitioning, the output of diskutil listing is:

/dev/disk2 (exterior, bodily):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *251.0 GB   disk2
   1:                        EFI EFI                     209.7 MB   disk2s1
   2:       Microsoft Fundamental Knowledge HDD                     250.8 GB   disk2s2

After transferring just a few information (JPG and PDF) to the disk and connecting it to a Home windows machine, I obtained a message saying “There’s a drawback with this drive. Scan the drive now and repair it.” If I ignore the message, the disk opens and I can entry most information besides some PDFs, which initially open high-quality on my Mac. Nonetheless, as soon as I attempt to open these PDFs on Home windows, they develop into corrupt, and reconnecting the HDD again to my Mac doesn’t permit me to open the information. Within the file listing, they seem greyed out. Furthermore, the issue remains to be there if I choose the choice scan and repair the disk on Home windows!

I adopted the identical course of with one other disk with none issues. For context, this disk was once the inner HDD drive of my Mac, which I changed, and I needed to repurpose it as an exterior disk. Why do I get this “repair disk” error on Home windows, and why do some information develop into inaccessible?

Edit:

I used Disk Utility, chosen “Present All Gadgets,” and erased the top-level exterior bodily disk. All information present up usually once I use the disk on Home windows now, however the “repair disk” error nonetheless seems. If I press “repair,” it says the disk is mounted, however the error reappears once I unplug and plug it again in.
