I've recently bought a Mac, and I want to share my Seagate FreeAgent 1.5 TB external hard drive with both my Mac and my PC. I've searched and found that exFAT or UDF is the way to go to have read/write access on both platforms. I've gone with UDF (I've read that exFAT is better for flash drives and it is also proprietary hence no official linux support -- if I ever need it just in case) and when I plug it in the Windows (where I formatted it as UDF) it works fine. When I plug it into my Mac, it says the drive can't be read and offers me to format it or eject it. When I go to disk utility, it shows the drive formatted as exFat (no I'm sure it is not. It is UDF, I formatted it from the command line with UDF option and it shows as "UDF" under Windows). I try to verify/repair the disk and here is the screenshot of what I get:
What could be the cause of the problem and how can I solve it?
