Do you particularly want/need to buy a replacement (internal) drive Hans, 'coz external drives are
much faster (almost 3x!), and won't cost you much more?
For instance... this (retail)
22x Samsung SE-S224Q/RSMN costs just
£33.26
If the wife takes the laptop on the road though, then obviously a replacement is the way to go, and
Scan offer a decent enough range
Surprisingly... the very first drive on that page is a Pioneer, which are a
very highly respected brand... yet it's the cheapest they sell
You'll just need to make sure you buy the right format drive - i.e. IDE or SATA.
It's most likely IDE, but double-check anyway
