Recovering your Acer Aspire One can be done without too much trouble. The only thing you need is a file,  a mac, usb drive/stick and a set of decent instructions. The latter is on this page ;).

note: These instructions are for OSX users.

Download the recovery image

With some help from Google I found the following working recovery image here (~ 1GB).

Put it on your USB device
No, it’s not that easy but doable if you follow these steps:

- Insert the USB device
- Open Terminal
- Type:  sudo mount 

bash-3.2# mount
/dev/disk0s2 on / (hfs, local, journaled)
devfs on /dev (devfs, local)
fdesc on /dev (fdesc, union)
map -hosts on /net (autofs, automounted)
map auto_home on /home (autofs, automounted)
/dev/disk1s1 on /Volumes/STICK (msdos, local, nodev, nosuid, noowners)

- Output will look much like above. The line with the name of your USB device is important. In the example it’s /Volumes/STICK. look carefully at the first part, /dev/…..
- Now forget s1, s2 or anything like that. So that leaves /dev/disk1 or /dev/blah2 or something.
- Type diskutil umountdisk /dev/disk1
- If umount was a success (jay) you can proceed
- Type the following: gzcat aa1_usb_recovery_image.gz| dd of=/dev/disk1
- Do something important, this will take a while
- When the command above is finished, you will get back to a prompt, now pull the USB device out
- Insert the USB device in your Aspire One and press the power button
- Press F12 in the first screen and select your USB device
- Now go ahead and recover! 

This is how I recovered my little Aspire One. Hope it’ll help you out  ]]> http://jobd.net/2008/08/acer-aspire-one-recover-with-an-usb-stick-osx/feed/ 3406
