If writing a senior essay weren’t stressful enough, for Andrew Delman ’09, the situation just got worse.

A geology and geophysics major in Pierson College, Delman believes he lost his external hard drive at around 11:30 p.m. Monday night in Connecticut Hall. The black Seagate FreeAgent drive contains the most updated version of his thesis, including many of the figures, images and maps necessary for his presentation, which focuses on modeling coastal erosion.

Most of the data saved on the drive is otherwise unrecoverable unless he finds the device. While the final project is due April 29, a draft is due this week.

“Turning in a draft is going to be impossible unless I find the drive,” Delman said, adding that even making the final deadline is going to be a struggle. “I don’t know. If I work day and night it may be done in time.”
