I was recently doing some updates on a CentOS server, and one of the packages that showed needing an update was OpenSSH (you can see what needs update by running yum check-update). I'm always nervous about updating OpenSSH while connected to the server over SSH, will I loose my connection?.

Everything went fine, and my ssh connection remained intact while updating OpenSSH on CentOS using YUM.

I have a 1TB USB drive connected to my Airport, and sometimes when I try copying large files (multiple GB) files to it I get the following error message:

Sorry, the operation could not be completed because an unexpected error occurred. (Error code 0)

First I thought maybe it was a problem with using my AirPort, so I tried connecting it directly to my Mac, same error.

It turns out the problem is that the USB hard drive was formatted using FAT32 (this is how they often come from the manufacturer, I never reformatted it), which only allows files of max size of around 4gb, when you try to copy anything larger you get this unexpected error.

The solution to this problem is:

• Backup everything on your USB drive
• Reformat the drive using something other than FAT, such as "Mac OS Extended"
