Thanks, appreciated.

Hmm.  I've got one stick of ram out of the machine due to testing as I 
had some freezes last week.
If it were one of the RAM, PSU and CPU then I'm unsure why this IO issue 
only surfaces on the HDD and not the SSD.  I ordered a new HDD last 
night, before reading your post.  If its not the disk I'll go raid1.  If 
it is the disk then I'll probally find out.

Well, first option is to drop in the new disk, freshly format it and 
copy the data across (not add it as a second disk).  If that fails last 
backup was wednesday.  I've not done much of note since then apart from 
try to fix the disk issues.
