fixed : quickly free up disk space on MacOSX 10.6.8 Snow Leopard

Question :

My son alarmed me today that his ‘good old’ Mac gives a “your startup disk is full” warning at startup. He has our old Intel CoreDuo MacBook that can only run MacOSX 10.6.8 Snow Leopard.

What is the easiest way to free up the much needed harddrive space ?

 

Answer :

There  are various programs that can do the job of identifying which files are cluttering your harddrive and deleting unneeded files.

If you have an older Mac that can not run the latest version of OSX, I would suggest using the DiskWave application to do so, because of 4 reasons :

  1. DiskWave is very small in size (only about 1MB), so you can even install and run it on an extremely full harddrive
  2. DiskWave is able to manage external drives, so you can also run it on a newer/faster/other Mac and connect the problematic Mac as an external drive [ in so called “Target Mode” by restarting the problematic Mac with the T-key pressed and connecting it to the other Mac with a FireWire-cable ]
  3. DiskWave is available for various old versions of MacOSX
  4. DiskWave is FREE to download and use

Using DiskWave is rather straight forward. A quick instruction video can be seen here :

Getting hold of DiskWave might be problematic however, as the developer’s website (Aymeric Barthe) seems to be down :

And the DiskWave app is NOT available from the Mac AppStore either… [ beware not too be fooled into thinking it’s the same as the iDiskWave app ! ]

A secondary problem is that the best available version (DiskWave 0.4) does not support any pre-Core2Duo. For now, all (older) versions of DiskWave can be downloaded here :

download any DiskWave version at Mac.FileHorse.com

Note that DiskWave 0.3.2 is the latest version of DiskWave to run on PowerPC (G3/G4/G5) Macs and 1st generation Intel (CoreSolo and CoreDuo) Macs.

And if those links stop working also, you can download DiskWave 0.3.2 here :

DiskWave_0.3.2

[ !! after downloading, replace the .doc file-extension by .dmg to get the installer !! ]

fixed : “No Volumes Found in backup”-error

Question :

I was trying to get Migration Assistant-app to put all my data on my new Mac, but when I select the sparsebundle backup-file from Time Machine in Migration Assistant, I get an error : “No Volumes Found in backup”.

How can that be ? I’ve made a new TimeMachine-backup just minutes before, and I didn’t get any errors there… what is wrong ?

What can I do to fix this ?

Answer :

Time Machine is great. But there seems to be a bug in the backup-software that causes this “No Volumes Found in backup”-error you’ve encountered. Normally, this error-message should only be displayed when a sparsebundle backup-file is corrupt (for some reason), but it turns out that it is now also displayed when a sparsebundle backup-file is incomplete…

This is probably due to a disconnection from the backup-disk during the TimeMachine-backup process (for instance because of shutting down the Mac, or switching from WiFi- to Ethernet-connection or vice-versa, during backup).

If the original files are still available on your Mac, the solution is rather simple : just go back to your Mac and use Time Machine to make a new backup. If you want extra insurance to prevent this error, either make a new Time Machine backup to a new/fresh harddrive (preferable an external USB- or FireWire-harddisk), or follow the backup-routine outlined in this post.

If the original files are no longer available on your Mac (e.g. your Mac is stolen, sold or you’ve just done a clean install on it, wiping off all of it’s data), you are in trouble…

…in that case, you could try using Disk Utility to repair the sparsebundle-file. If that works, you are in extreme luck… if that doesn’t help, you have very few options other than using the Terminal-app or a specialized expensive retrieving app like DiskWarrior (the cheaper knock-offs turn out not to work in most cases… too bad…).

I will be posting instructions on how to use the Terminal-app for this shortly (in a new post).
