When SSD was not recognized, the sky seemed to be falling. 🙁
[ My SSD spec ]
* intel SSD 535 Series 240 ( SSDSC2BW240H6 )
* controller : Intel BF29AS41BB0 8-channel NAND flash controller ( = converted Sendforce SF-2281 )
I was giving up.. but I saw the answer from the DERA BOR Data Recovery that was possible a solve in at a forum( hddguru ).
It was a small possibility, I decided to restore.
The result was a 100% successful recovery! (It seems to have taken a little less than two months from the estimate to receiving the recovery media. )
The systematic recover system, which was divided into 'CRM', 'feedback', and 'professional engineer', was also satisfactory. Above all, I think they are identified as a company with the best data recovery technology.
The cost of restoration was higher than that of other companies. but if I had to Definite the data recover, I recommend DERA BOR Data Recoveryy!
