IXpand flash drive not displayed in Windows Explorer/IOS

Today the flash drive stopped working. On the iphone, in principle, it is not visible in the program, on the windows operating system, it is displayed in the file system, but it is gray. It is impossible to format and interact, but there is one in the disk manager, but without volume markup. A year of warranty has not passed, is there an opportunity to restore or return under warranty?
