may effect large ssd only?
iMac 24″, macOS 12.7
FWIW my anecdote: few years ago formatting with Disk Utility as exFAT (MBR) worked better than exFAT (GUID). Windows 10 saw only about 32 GB of the latter while of the former it saw the whole 128 GB.
But things might have changed because Apple has changed exFAT underpinnings in Sequoia and it might still have teething problems.
Thanks guys,
It may be because the large drive's "allocation unit" size (which is a function of the drive capacity) that is generated by the Mac during formatting process is not compatible with the Windows file system (my drives are 2TB). It appears that, for some, having the Windows software doing the formatting as exFAT will create a drive that is read/write with no problems and is useable by both Mac and Windows systems. But I don't know the capacity of the drives that will or will not work. So that is my question.
FWIW, a 64 GB ExFAT flash drive formatted on an M3 iMac works fine on my ancient ASUS Windows 10 laptop. I don't have an SSD I'm willing to reformat to test.
