Any complaints with exFat?

Hey all,

Was interested in reformatting my HFS+ backup solution as exFat for better compatibility between systems (my enclosure always freaks out when I'm on the Windows side). My question is this... does anyone have any complaints with exFat? Just wanted to make sure it's worth my time since I'll have to borrow a 600GB+ hard drive to reformat. Thanks!

What backup solution are you using? With exFat you don't have the same level meta-data support built into the file system. This may cause issues when doing a restore.

Any backup solutions I have, include a device that can store the metadata or is completely Time Machine compatible. With exFat, will Time Machine work?

I doubt Time Machine will work on exFAT the same way as HFS+. It might back up as a sparseimage, though.

    • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
    • Some have reported problems using Tuxera (approx $36).
    • Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
  • AirPort Extreme (802.11n) and Time Capsule do not support NTFS

What exactly is metadata support? I'm debating between using HFS or exFAT to format my external harddrive which will store large movie files and music files. Is exFAT very unreliable?

I already have a time machine 500gb bought from market place here. So no need for that. But exfat is good for my new 3tb toshiba I got from bestbuy. It works great mac mini 2.3 i5 8gb ram and 10.7. No problems here. Now I have to try my windows 8 laptop and see what it does. But no issues on the mac side.

I thought exFAT was a holy grail of sorts. I no longer like it at all.

Time Machine won't back it up. Neither will any Windows solution I've tried.

Also, OS X cannot network share an exFAT partition. It will let you set it up as a network share, but it doesn't work.

On the Windows 7 side I've occasionally had Windows think that the drive was corrupt and so it would treat it as a read-only drive until I perform a chkdsk. So I'd perform a chkdsk and it wouldn't find any errors, but at least it would restore write access. Really irritating. Also scary, since I can't conveniently back the damn thing up.
