I have a macbook pro 13" mid 2009 2,26GHz with HDD 160gb. I recently replaced my optical drive with a crucial SSD 240GB and it works really good and it was quite an easy process. Now i am trying to do the same to a friends Macbook pro 13" mid 2010 with a crucial MX200 SSD 500gb, only now
it is not recognisable at all by the MBP.
- both sata drives on MBP 2010 are on 3gb/s speeds while the ssd is 6gb/s!
- Both macbook run el capitan
I tried disk utilities , i tried restarting with cmd + R and again is not there. I also replaced my friends sata cable with mine (which works fine) and still nothing. I am looking to several articles over the net and the most hopeful case is to replace the sata cable from the ssd to the board. If thats the case i will not have to return the item or lose my money but just buy a new cable.
Basically, do some SATA cables prevent negotiation to 6Gbps or is the 3 Gbps something to ignore and instead focus on maybe the adaptor i got to fit in the new ssd might be broken somewhere in the connection?

I suggest trying to put the SuperDrive back, and then seeing if the SATA cable for that works, if it does, you can switch the HDD for the SSD to check if it's faulty.
Also - there are inexpensive power supply / USB data connection kits so you could get one of those and test the bracket you purchased external to either MacBook and see if everything works over USB first.
I wouldn't worry about a link negotiation between 3 Gbps or 6 Gbps - either will result in things working and even in the most stringent benchmark - it's almost never you are seeing more than 3 Gbps on a sata link so in practice you see no benefit from that - certainly not a cause for a drive not showing up entirely.
