A method of operating a memory device adapted for determining a programerase state of a memory cell in the memory device. A shell case entering a workstation tool strikes a sleeve by end-to-end contact, raising the sleeve in direct proportion to any excess length of the shell case. The method further includes obtaining an acknowledging response from the storage device, multiplying the obtained acknowledging response, and sending respective acknowledgements to each source that initiated each respective \u201cwrite\u201d request. The fastener may include a magnetically attractable material disposed along a center region of the upper surface of the base.
