If you have already put files on it, initializing will most likely delete everything!

I assume "initialize" refers to Windows asking if it should format the hard drive.

If your drive is suddenly not recognized, the filesystem has probably gone bad. This can happen if you disconnect the drive while data is still being written to it. For this reason you should always "safely remove" USB drives.
If the filesystem is corrupted and cannot be accessed, you might be able to save your data by using special recovery software. One tool of the trade is the commandline-based "testdisk" utility for Linux, which I have succesfully used to restore entire filesystems without any data loss.

If you want to rescue your data, the worst thing you can do now is to initialize the drive or use it in any way that changes the content.

If you don't care whether the content is deleted, just initialize it or do whatever it takes for it to be recognized.

Please state if you want help on restoring your data.

if the thumb drive is not recognizing in your system then connect to some other system if its visible there recovery your data from there in some other storage media. And if it is not visible in the other system also then to save and recover your data use data recovery software.

If your machine does not recognize the hard drive at all it will be very difficult for you to restore anything.
You can look into data recovery services where you would send the drive away and they would restore what data they could off the drive. Though be warned this can be very expensive.

I believe the keyboard wants COMPRESSED type filles such as MP2 or MP3. Try those.

the nokia 3110 is not a powerful device it will surely not recognise the sim because it contained the data which might be copied to the phone memory as well as the sim card so during the sim after being wet & dry was certainly not going to be recognized by the cell as its data was corrupted

data is lost,
test with H2testW'
fix with PD V1.08 B3
good luck !

Maybe the catweasel universal floppy disk controller can help?
