External Hard Drive

Hello,

I have an external hard drive for my mac computer. It is a G Drive Slim with 500 GB of space on it. I'm trying to back up my computer and it's telling me there is not enough room on the hard drive to back up (via time machine) so noting is backing up. I've deleted pretty much everything on the external hard drive and put it in my trash, but the space available does not change. Why is the available space not changing even after I trash the files? Help....

the data  are still resident until you actually delete the trash which purges the associated record

the data space is then availble to be overwritten

also u did not mention the size of the PC

ie cannot copy 750 gb to 500 gb drive

Is there a way I can only delete the items that I deleted from my external hard drive from my trash instead of deleting the entire trash itself? I'm on an iMac. I tried deleting them, but it seems like it's only letting me delete the entire trash can, not just specific contents.

You can only delete the entire trash. So if there is stuff in the trash you don't want to delete, move it out of the trash into a folder, then delete the rest.

This is why it is a very bad idea to use your trash as an archive. Don't put anything in the trash that you don't actually want to delete. Save it elsewhere.

so in windows you can selectivly delete parts and pieces

and as mentioned trash is trash....

on Mac can do selective with 3rd party tools

imho - best to delete all

On a Mac, you can selectively delete files via the command line.

open a Terminal Window and type the following commands, replacing VOLUME_NAME with the name of your external drive.

cd /Volumes/VOLUME_NAME/
rm -r .Trash/*

You could also do a quick format of the external disk, or just remove everything from the external drive.  
rm -r /Volumes/VOLUME_NAME/*
rm -r /Volumes/VOLUME_NAME/.??*

I don't like using the Trash Folder so I mostly delete items via the command line.  On Windows you can do a control+Delete to force a delete without putting it in the recycle bin.  There is a 3rd party tool for the mac to force a delete without going to the Trash if you aren't comfortable with the command line.
