Alex - Do you have a universal adapter cable or external case to put the SSD into? See if it can be for formatted externally. If you can, you either have a SSD thats too fast for your system (SATA III Vs SATA II) or the drives SATA cable is bad.

If it were a normal hard drive I would use the "write zeros", format option to map out any bad blocks. It might work for the SSD.

This problem has nothing to do with the drive itself but is almost always caused by a bad connector between the board and hard drive. A large proportion ,around 10%, of macbooks that come into my lab for disk replacement have a perfectly good drive but a bad cable the problem seems to be most prevalent in the 2010 macbook pro

Dani, Agreed, most of the time its the SATA cable. I'm sure Alex has since fixed his system given the age of the original posting. How about focusing on the newer ones.

Hi, what about MacBook Air 11" 2012 where there is no SATA cable?

The SSD's firmware is likely corrupt or the SATA controller in the laptop or the drive is failing. The SATA cable has nothing to do with it. All SATA devices are backwards compatible with SATA III, III, and I, as per the SATA spec. The drive will just downspeed to the correct protocol.
