Although at first sight it
looks as though one small Phillips screwdriver would fit all the
screws
you need to remove to change laptop hard drives, in fact
you need two.
You’ll soon find which size works best for each
screw, but the lower one with the yellow handle
in the picture
below is slightly magnetic which can be a great help when you don’t
want
to drop a screw inside a computer.
The one at the bottom of
the picture should be in the middle drawer of the office desk in the
tray of tools
(unless it’s been left on a table somewhere
because I was using it). The other one is
from the set of small
screwdrivers (as shown) which is usually kept in the top draw of the
office desk.
The end you need is shown below
And it should be
kept in the missing place in the set shown below.
