I know that I can reformat the whole external drive and delete partitions and recreate them, etc. now my question is, if Iíd like to simply change itís size, will I loose everything that is on that drive? Thatís one info I canít seem to find anywhereÖ I donít dare to try, however.

I sadly found out that the partition that I created for time machine is too small. :(

If the partition is in HFS+, then Disk Utility can resize it non-destructively.

What does that mean?

Yeah I noticed that in disk utility it said that the selected partition will not be modified or something like this, but it confuses me. It obviously will be modified if I change itís size, it just wonít be reformatted. Maybe thatís what they mean?

HFS+ is the Mac OS Extended option you see in Disk Util. The fact that you are using this disk for TM means it is already in this format, so you are fine.

Just follow this (http://osxdaily.com/2009/11/20/resize-partitions-in-mac-os-x-with-disk-utility/) to resize. All that message means is the partition you are resizing will not be erased.

I just checked the various partitions and drives (Macintosh HD and external hard drive) and it says the format is ďMac OS Extended (Journaled)Ē for all of them, I guess itís the same and it should be fine then? :)

Iíll follow that link you gave me, so itís 100% sure that if I resize my partition everything will stay the way it was except that Iíll have more space on that partition, right? Also, I need to make the ďMainĒ partition (rest of the external hard drive that I use to store other random stuff) smaller, this isnít a problem is it?

Cause Iíve read something about you being able to make them bigger but not smaller or something like this :confused:

You can make the partition larger or smaller without losing data. When making it smaller of course you don't want to make it smaller than the amount of data on the partition. But no, just resizing does not wipe data.

That said, it is always a good idea to backup just to be safe when tinkering around like this. :)
