I Have a Toshiba 8GB USB that change into RAW file system, So,windows don't recognize this. I have some important data on it, whenever i try to open this prompt a message "you require to format the drive." Somebody recommend me scan with mini tool partition wizard and may also use Test Disk. I try with TestDisk 6.14 and mini tool partition wizard server edition 7.5 to get back my USB but not get success. I also used the mini tool partition wizard Home edition 8.1 but don't get my USB.
So after this I decided to format my USB with default File System (FAT32 file system) but USB don't format .i try this many time with different file system but USB doesn't formatted.Now my USB not shown in My Computer and this is shown in window disk management as a not initialized disk . So I try to initialized this with MBR partition and GPT partition style prompt a message is "Device is not Ready", Now what should I do.
Now USB not shown in "My computer" while USB shown in windows disk management as a not initialized disk.
