Wiped out partition on my book essentila external hard drive

WIPED OUT PARTITION ON MY BOOK ESSENTILA EXTERNAL HARD DRIVE, now my windows XP does not recognize the HDD. How do I install a new partioion? Disk management does not recognize it either  HDD is now in UDF and stiil shows Smartware.

That’s a good sign, if it’s showing the Smartware VCD partition without the drive on disk management, then it simply means the drive is locked: Open the Smartware VCD (UDF partition) and unlock the drive.
