BitLocker Password

Try again in an "elevated" command prompt (click on link) instead.

Just opening a command prompt while logged in as an administrator doesn't make it an elevated command prompt. You'll need to do what's in the link above to right click "Run as administrator" to do so instead.

You might try again in case you may have made a mistake entering the password. The password is case sensitive.

Since you do not have a backup of the recovery key or startup key for the USB encrypted by BitLocker to use to recover it, then you may be pretty much out of luck.

Unfortunately, that's the whole point of BitLocker. No key = no access.

If the data is really important, you could try using a professional data recovery service to retrieve the data, but it's not cheap to do so.

You of course could format the USB to be able to use it again, but you will lose all current data on it as well.

You might see if this one below may be able to help.
