Hey guys,
Thanks for your help so far.
I shall try reformatting it.
And thank you for the shortcuts is well, it's nice to get them explained as some things I'm realizing are just apple quirks.
Let us know if you need any more help... once you get a hang of OS X, it makes you wonder how did you endure those windows years.
About the shortcuts, check
this and
this out. They are simple tables of functions with their Windows and OS X equivalents. I'm sure this will help.
Now, about the drive... There are several types of formats for drives... If this external drive is high capacity (>32GB) then you should use either:
a) NTFS (windows compatible, but you'll need a 3rd party app to format and write on it, as you've seen).... if this drive is to be used mostly with PCs or smart TVs... or
b) Mac OS Extended format (jornaled) if this drive will only be used with Macs. More on this below.
FAT32 is usually reserved for thumb drives and small capacity drives - as it's not very efficient for high capacity drives, even when OS X can read/write them natively. ExFAT is a newer format (relatively) and while it has no practical limits on capacity, it also seems to work better for flash/thumb drives.
Here is a clear explanation on these Windows options.
Here are some simple instructions on OS X drive formatting - ignore the Apperture part.
It's also important to note that you can partition the drive (create two separate volumes on one drive) and have one partition as Mac OS Extended (journaled) for OS X, and another one as NTFS for Windows, in case its a shared drive - but I wouldn't recommend doing this if the files are critical or backup files, since sharing such drive poses obvious dangers.
So, in case you wish several partitions, or if you plan to use the drive as a backup/clone/system startup drive (OS X or windows), you should also check the type of partition when you format it,
as explained here.
Hope this helps. Good luck.
