HELP : I cannot use acronis with my brand new Sandisk Ultra II

how are you connecting the ssd to the computer? some SATA to USB cables do not pass the drive info through to the PC so the software cant recognize it as a WD or sandisk ssd. You may want to try a different cable or enclosure. 

If that does not work or if you do not have another contact sandisk support. They may have another solution for you to try.
