Hi,
I have the same problems with my plus 240gb, SanDisk registered and set the waranty up for me after several failiers.
Then I couldn’t get my files and documents to transfer over from my disc to the SSD PLUS.
After much backwards and forwards with SanDisk I recieved an email with the new upgrade on.
I downloaded then nothing the Dashboard wouldn’t load fully.
Back to sqaure one in la la land.
