I am messing with the hard drives in both my FreeView and Freesat boxes at the moment to try and clone my SD recordings on both boxes to end up with 1000 Gb drives fitted to both. I will soon be having a brand new never used 500Gb manufacturer fitted drive I pulled out of my new box up for grabs.
So far I have learned a lot about formatting Linux hard drives, large file transfers and recovery on an XP PC!
The switchmode power supplies in both units are open frame, well worse than that because most open frame units have a protection cover over them and these do not. That means they are VERY dangerous for anybody unskilled poking around inside with the covers off and a mains supply connected - even in standby. Mains contacts on the input switch are sleeved, but there are other high voltage points to make accidental contact.
If the OP touched a hard drive and got a shock, then either he was touching something else as well or something is WRONG. By wrong, could mean there is a problem with the power supply making it unsafe and the OP does not know. The only way to tell is to check the insulation from the case metalwork to the mains input connector.
There are plenty of links out there on buying the right spec. hard drive, and fitting it. The big CAUTION is always work with the mains plug removed and only put it back when the cover is on.
Most power supplies like this can still store voltages up to about 380 volts for some time after removing the mains plug, so keep fingers well away or put some temporary parcel tape over the unit first. If you don't know what a mains power supply looks like then you should not be poking around inside. It is the unit on the left that has the mains plug and on/off switch connected to it!!
I would not let my family near my Humax if I got a shock for reasons I did not understand and thought it was unsafe.
it is very easy to touch the power supply and destroy it.
AND yourself.
