Sandisk SD Express corrupted after two days? Please help!
I just bought a 512gb Sandisk GamePlay Micro SD Express card for my new Switch 2. I popped it in on Monday, did some transfers and everything was fine. Played a game last night for a few hours, then put the console to sleep and went to bed.
Went to play a game today, and suddenly my Switch says the card is unreadable... I popped the card into my laptop and it won’t read at all. Reading online I’ve learned about some instances of a card becoming corrupted during updates, an eshop bug (?), etc. But I haven’t had the internet in my home since yesterday morning (a line came down and has yet to be repaired). So I haven’t even had a connection, and again everything was working fine last night.
Did my brand new, reputably branded and certainly-not-counterfeit SD card seriously just crap out after two days? And do I go back to the retailer (Walmart, bought online) or do I submit a warranty claim through Sandisk? Luckily I found my packaging in the recycling, but I don’t know how to proceed. Any help or advice would be much appreciated!! 🙏
