Can't mount external hd partition on mac only

[mrmaster]

Hi,

I have a 1TB external Buffalo HD with 2 partitions. I use one partition for Time Machine backups, the other one for files.

Today, I plugged in the HD and only one partition - the Time Machine one - showed up. I restarted my Macbook Air both with the HD connected as well as disconnected. I did that again on the other USB port. I ran Disk Utility (it didn't find anything); I booted into recovery mode ran disk utility there. I also ran fsck_hfs with the -dy, -fy, -drf options. I also tried to mount in readOnly mode with diskutil. No change.

As a last step I decided to connect the HD to my Linux virtual machine.There, both partitions showed up just fine and with all my files. So it must be something that's Mac-specific. Can anyone help me get this back up running?

Thanks!

Probably best to show us screenshots of what Disk Utility and the System Report say they can see...

Thanks for the reply. Disk Utility couldn't find anything wrong with the partition. It was mounted read only in linux and it took forever to copy stuff off it, so I decided to install DiskWarrior. It fixed the problem within 5 minutes.... Well worth the money.

thanks
