Hello, I would recommend 'Tun-O-Wash' made by Chemtronics in
the USA, I believe a firm called Tri-state electronics carries
it. Honestly, I use it mostly on older game consoles, hi-fi equipment, etc.
but it has worked great for me....Bad points: it's about $20.00 USD
per can, and should really be used in a well-ventilated area,
the fumes can bother a person
Good luck with your drive, my one HD drive lasted about 6 months
before it died for no reason in my A1200T, maybe they are very sensitive to dust?
