Can anyone who has actually changed the HD in their macbook let me know which screwdriver you used?
I've seen many people saying different sized Torx, some say T5, while others say as high as T9.

Thanks
 
Is that sata>usb just the same as an 'icy' enclosure?

Here's a good question too. Any drive, once up and running, always actually gives you less space than it is. E.g. a 120gb drive actually gives you 90gb to use.
Is there a forumla to work this out for all drives. Is it always 1/4 of the drive that's lost?

120GB to 90GB?! Don't think so. My iPod is 30GB but formatted space is about 27GB, so the formatted size is about a 10th less.
 
The sata to usb does the same as the enclosures but you basically just get the cables which makes it cheaper than getting it with the enclosure.

The reason for the differing hard drive size is below.

For simplicity and consistency, hard drive manufacturers define a megabyte as 1,000,000 bytes and a gigabyte as 1,000,000,000 bytes. This is a decimal (base 10) measurement and is the industry standard. However, certain system BIOSs, FDISK and Windows define a megabyte as 1,048,576 bytes and a gigabyte as 1,073,741,824 bytes. Mac systems also use these values. These are binary (base 2) measurements.

Erm no it doesn't.

Mine is 111.5gb formatted, something seriously wrong with yours!

OEM Recovery Partition?
 
The space differences are due to the hazy definition of the term gigabyte

Hard drive manufacturers consider 1000^3 bytes to be a gigabyte (there'll usually be a disclaimer alluding to this).
All software including OSs consider 1024^3 bytes to be a gigabyte.

These days you're supposed to use gibibyte (GiB) for the 1024^3 bytes situation (i.e. you actually have 4GiB RAM and a 100GB hard disk) but no one knows or cares
