My USB flash drive was plugged into an infected PC, and now it contains viruses. Actually, that flash drive was filled with stuff I wanted to transfer to my Android. So I decided to use that flash drive on my phone anyway (via otg) considering those PC viruses would not affect an Android. It went well in the beginning, I transferred files successfully, but now the flash drive shows size 0 bytes when I connect it to phone. Is there any app that could help me? My phone is sadly non rooted and I can't root it without PC I guess.
