WinDlg1.31 does not list Full Erase, & won't allow for an all zero format

When needing to rewrite a WD5000AAKK=00K13 SCSI drive to all zeros the WinDlg1.31 was used as instructed. However, it only allows for one selection rather than two. (Quick Erase, or Full Erase) The only option is “Erase”. When Erase is selected a popup says the drive is the Windows system and must not be erased. What should I use to do a LLF to rewrite the drive to all zeros?

Hello,

Is this your primary drive? Does it have an Operating system installed?
