How to copy data from non starting MBA? My old MBA (2008) is not booting anymore from hdd. I tried to repair it with disk repair and with a DiskWarrior CD-ROM, but nothing. I need to copy some data from the hdd, before replacing it.

Any ideas on how to do that?
I would started with getting that drive out of MBA with the instruction from iFixit for example.

Then I would buy one of these IDE to 40 pin ZIF adapters and find yourself old PC or Mac with IDE connection.

Fire up DiskWarrior or R-Studio (on Windows) or better and cheaper with DDRescue.
If you want to check if HDD is physically sound you might also try MHDD or Victoria tools (they are DOS and Windows only though).

And if you want to replace that HDD better go with SSD. At least 64GB SSD will do big boost to this old bugger. Provided you have Nvidia in yours. If it is intel I would just replace HDD and sell it.
