Model: SanDisk Ultra® Dual Drive Luxe USB Type-C™ Flash Drive 512GB
Hi admins, a few months ago, I have purchased the above mentioned flash drive from a computer hardware store. It works fine on both pc and mobile phone, until it suddenly could not accept anymore files. After few rounds of troubleshooting, I noticed that the flash drive stopped working after 16GB. I am still able to access the 16GB of files in the flash drive, but could not add any further.
