Uncommon usage, technical jargon, verb, meaning 'to erase'.

Comes from 'eeproms' (Electrically Eraseable Programmable Read Only Memory) units in days of yore which were 'flashed' so they could be written on again. Typically, a computer geek would understand this usage.
PC Onwer: "So, should I through my broken computer in the trash?"

Technician: "Make sure you flash the drive first, for security reasons."

PC Onwer: "WTF?"

Tech: "Uhh...erase all the information."
