Morning sir! what will happen to my data in my

Hello, you just have formatted your pen drive without extracting data inside at first? Why do you have to format that USB pen drive without rescuing data out? Is it asking you to format and its file system become RAW weirdly? OK! No matter why you have to format that USB drive, the data stored inside after format often will not really be completely wiped.
Without fresh data to overwritten it all there, you do get chances to recover lost from this formatted pen drive with Pen drive RAW file system recovery software which often will deeply scan your assigned flash drive and take all possible recoverable stuffs back.
Therefore, do not give up and go search for related data recovery software to go on.
Hope you can make drive data backups well before any format.

All your data will be erased & used space of your pen drive will restore to 0 bytes.
