Yeah! You can go for a hard drive recovery freeware that helps me when my SanDisk Blade 4GB USB Flash Drive show RAW.
Afterwards, you could format this drive to see whether it could work normally. Note:
1. Do not store any new data on the same drive to avoid original data overwritten by new data, which can make your data gone forever.
2. Do not save the recovered data on the same drive, which can cause recovery failure.
3. Do not forget to format this drive to fix it.
4. Do not forget to back up your important data regularly in the future.
