My 480 Ultra II died 4 months after install. I have to go to BB to get a receipt printed to do RMA. I have owned many drives, this was my first SD. I thought since the USB drives are so robust they had to know what they were doing. Nope- Back to SAMSUNG for me. What a pain in the neck, and Web search finds this a common issue where drives fail with no notice.
Doing some research tonight was necessitated after my fourth in a low number of drives having failed today. There is a fair amount of discourse concerning drives that were somehow firmware-frozen, for lack of a better term. They can be brought back from non-detection by simply powering them idle, with/without a SATA cable (depedent on the source) on the BIOS screen.
Yup , just had one Ultra II die on me just the other day after about 18 months (used in older Evga X58 desktop) and going to do an rma today (finally found the receipt) . Still have one in a laptop going on 2yrs with no problems .
If it is not detected in the BIOS it will need to be replaced. You will need to contact sandisk support to get an RMA. you can put in an online RMA request. return process may be different depending on what country you are in. Go to the link below and use the language selector at the top left. If you are in Europe make sure and use English (Europe) to get you to the right team.
Another to the list Ultra ii 480. no warning signs, woke up to dead pc, boots direct to bios. pulled and put into external dock and nothing. Have heard it could be a bad controller chip. If anyone has info on this repair please reply as I have some data I have to retrieve.
