Hi Jose!
Talking about weather is really good thing!
The problem is:
1. People want to do hdd/data recovery.
2. They want to do this professionally.
3. Remember? "If you want to do something well, do it yourself!"
4. People buy PC3000. What happens?
5. They STOP learning immediately because they start making money. Now they have "pc3000 stereotypes" in their minds. (btw: MHDD v4.3 will be capable to execute scripts in a way that you can write your own pc3000 using MHDD scripting engine.)
6. The first thing you should do is to get familiar with ATA/ATAPI standard. To try some commands with MHDD scripting engine. To see, how it works.
7. Then disassemble some very simple f/w update programs like dlss80c2 for fujitsu MPG to see how fujitsu drive works. (By the way, you will receive a good bonus because latest fujitsu laptop drives accept all old commands, so you will be able to repair drives such as MHT, MHU...)
In other words, to start learning you have to start hate PC3000
But first of all: everybody needs a good vacation.
