Hello to all Gurus

I have a question.
When a hard disk heads crashes (Knocking) we need same model, Config and Site code, to get the data.
Does different heads (site code) for the same hard disk make and model reads data differently. I.e Seagate ST160211AS hard disk with site code SS or WU or TK. reads the data in different pattern if yes Why if no then why to match site code.

You can PM me if you want

I like to think of it like

1: Paint .... Same colour but other batch is never quite the same
2: Wallpaper .... Same pattern same colour and you should always buy from the same batch

Also need to remember that not all heads are made in the same factory or from the same waffer.

for example 80% of heads are produced in the US and the other 20 % are from Singapore (IMHO) For Seagate drives I have my own reasoning..eg I try same model , same site and get the closest Serial number match. I don't think it always needs the same Config.

Maxtor uses many diff types of vendors for it's heads, same as Samsung. So TDK/SAE/READRITE all have their own personalities and not all cut from the same template.

Distribution drives have (Maybe Cheaper heads) one type of head, IBM maybe requires better heads and Dell could have other heads..All to their specs and MTBF quality standards ............blah..blah..blah

Anyway any other views?
