I know that some WD drives you cannot open due it disrupting the head alignment.

I was wondering which WD drives that applies to? Is it just the cavier greens?

There are a million posts about this. Read through the archives.

@iDan,

As drc said, you'll get up to speed better by reading the previous discussions, but your comment below is not correct:


Those drives can be opened - in fact they must be opened to replace the heads, for example. However then need special alignment techniques to be used afterwards, and those techniques are effectively trade secrets.

and tools that are supposed to solve this problems do not work ( to save You money )
