Yep, you read it correctly. I would like a way to crash my Mac OS x hard drive/hardware so that it cannot boot anymore. Through a software solution. This is because if my Macbook ever gets stolen I'd prefer to crash the damn thing rather than recovering data. (of course I have backups)
Is there any location on the hard drive on which finder or so is located? Is there a possibility to delete any of those files/folders using sudo in bash through some remote shell?
The best thing would probably be if I could delete the part of finder/OSX that browses the hard drive filesystem. Please also post your thoughts on any answers if you know something bad with that solution.
EDIT: thought #2: Corrupting the files in the folders? Is there a way of finding them on the hard drive and overwrite their contents with random data? (Maybe mount it using some non-standard driver through sudo?)
EDIT2: Is it possible to use two passwords when encrypting a hard drive? I.e. one that decrypts and mounts my "safe" part, which would be the OS, programs and so, while not decrypting the sensitive parts, and another password to do the rest of the decryption. I doesn't matter if this would end up as two different encrypted files on the disk as long as they are hidden.
Please note: I do not want an encryption-solution unless it can encrypt the hard drive in two parts; one for the OS and one for my files. Maybe encrypting the hard drive and then encrypting the sensitive once again through a bash command or something equally hidden? (no visible "/encrypted-data" folder which you cannot access)
Also, Would a "sudo rm -rf /sensitive/folders" from SSH do the job? Would it do it silently? (non-discoverable by someone looking at the Mac screen)
Edit 3: since this thread is running out of hand and i have posted small aditions all over the place i made a new thread with alot more clarity to the actual problem. Hope you understand why.

Mac OS 10.7 might have a remote wipe feature: http://blogs.computerworld.com/18225/imac_sandy_bridge_upgrade_hints_remote_wipe_for_mac_more

@Shinrai i would like to crash, erase and/or overwrite the disk. A new harddrive is free for me. – Filip Haglund – 2011-05-11T15:07:50.757
1@Filip - My point is simply that 'crash' doesn't generally mean 'irrecoverably damage the disk', it means 'the operating system goes down, and you have to reboot'. Semantics are important here, especially since you seem to dislike every answer you're getting. – Shinrai – 2011-05-11T15:19:49.633
oh, in that sense, yes. Thanks for pointing it out! – Filip Haglund – 2011-05-11T15:37:56.587
Just a hint : If the BIOS infos concerning the number of disks, number of heads per disk, number of sectors per side, etc. is wrongly set, doesn't it physical damage to the disk itself ? – Pierre Watelet – 2011-05-11T15:58:50.200
@Pierre: 0, Macs don't have the same kind of BIOS. 1, Current operating systems access disks directly, bypassing BIOS calls. 2, CHS addressing is never used anymore, only LBA. 3, For "modern" (all ATA/IDE) drives, CHS addressing doesn't even make sense anymore, and if it is used, the drive's firmware will automatically convert it to a working physical address.
