I decided that I need to test my Hard Disk migration procedure today. I am going to put an Apple RAID card in and use 4 x VelociRaptors. I Have my current system booting from a RAID0 setup and as such it will be a pain (in the arse) when it comes to moving the partition to the RAID5 (not much room for disks inside etc). So I searched my cupboard for a 'spare' SATA drive, but alas all I found was an old Seagate Cheetah (15K SCSI) and some random IDE drives. Then it struck me - the Time Capsule has a 500GB SATAII disk in it.... mmmm my mind began to turn over.....and my hand reached for the screwdriver. So I googled for some pics (to help me disassemble the TC). I found this excellent set http://www.flickr.com/photos/24254876@N03/sets/72157604011791554/ The disasembly was simple enough. 1) remove the rubber base. 2) unscrew all the teeny screws. 3) invert the unit (so its on its top case). 4) lift the metal cover off (carefully as it has a fan mounted to it). 5) pull the foam cover from the heat sensor on the drive. 6) unplug the sensor from the clip on the base of the disk. 7) hand over the drive, invert again to make the disk 'fall' gently out of its casing. 8) un-invert and unplug the SATA data and power connectors. 9) re-assemble the unit. (there is a step 10 for those wanting to put a replacement disk in place - remove the clip for the temperature sensor in readiness to glue it to a new disk) So now I plugged the Time Capsule back in and weyhey it works fine with no disk (with the obvious omission of backup facilities). I now have a perfect Seagate Barracuda 500GB SATA drive to test the restoring and booting of the backup. I wasnt going to post this but then figured why not as its useful information to know the TC will still work as an Airport Extreme Base Station without its hard disk. Also It is useful for those that want to replace their hard disk. I will put one of the barracuda 250GB drives in once I've migrated my boot drive off the software RAID. I hope this is useful to some of you.
