My Sandisk Extreme 120 GB has faild to boot. Booting it on sata hangs the computer, partitions are visible in diskutility, but hangs if any thing is tryed to fix the partitions or initialize the disk.
Hopefully you have backups. All data on an SSD is encrypted so depending on the type of failure data recovery may not be possible. That said if you do not have backups you can contact a company like LC technologies to inquire about data recovery.
Arthur…Or you have the option of going over to Knoll Ontrack Data Recovery and pickup one of the DIY EasyRecovery Professional software. Technicians available to walk you through the process, if need be. I have used the EasyRecovery Pro software, myself, on a number of my SSDs with great results.
