Extention Hardisk

Harddisk, I will always stay with Seagate and WD (Western Digital),
stay away from Hitachi, Samsung, Maxtor, they are less reliable.
Seagate is the best ... I have a RAID of it 5 of them.
They are very cheap, 700-800 for 400 GB ...
and you can get the cheap USB extension case, kid, for around 100-200 ...
Go to "Golden Computer center" in Shum shu Po ... MTR ...
Very simple...
Wireless router, should be plug and play, just open up XP device manager
and do "Scan for hardware change" will find it ...
if not so, there must be collision, try to uninstall some Network interface and re-install it.
hope all helps
