OSX with ExFat exterior drive not totally accessible from Home windows purchasers

Because the title says, I’ve an outdated Mac working 10.13 (Excessive Sierra) with an 16TB exterior drive formatted to ExFat that serves as my important “backup” drive for each pc in my house.

Some background: I used to have a 5TB drive (formatted as HFS+) for this and all the things (i.e. all of the situations listed under that are not engaged on the brand new drive) labored flawlessly. However house was working low so I wished to improve to a more recent one. Provided that my Mac can also be fairly outdated, I wished the brand new drive formatted in ExFat so when the Mac dies I might then, and solely then, swap it to a more recent PC.

The problems: On the Mac, I can copy the information to the brand new drive utilizing Past Examine and my cloud backup service appears to haven’t any downside seeing the brand new information and even thinks they match with the present backup set so it would not attempt to add them once more. That is nice.
However on all my Home windows machines that join it, issues began to not work with the brand new drive. Chrome cannot save downloads to it and offers a totally unspecified error. I can not manually add information to the drive. As an example I connect with the drive and open up an current folder. I can see information in there. But when I right-click and select New -> Wealthy Textual content Doc, Home windows instantly says “Unable to create file ‘foo’. There’s not sufficient house on the disk.” Winamp can now not scan the folders on the brand new drive (I can not discover any errors). There are different oddities however these are the primary ones for me. Like I stated above, all of those situations work effective when connecting to the older HFS+ drive from my Home windows machines however not the brand new ExFat drive. And I can do all the things on the Mac with no points (a minimum of with Chrome downloads and creating information). I’ve tried connecting to the drive by way of and making an attempt to share particular person folders on the drive. Similar outcomes. It appears to be how the Mac is opening connections to Home windows however I do not know what the repair is, if any.

Any concepts right here could be appreciated. However I am eager on holding the backup drive on the Mac so long as that machine is working.
