As Quarren said in the episode, "Three weeks ago our research team found a data storage device buried nine meters beneath the ruins at Kesef. I've confirmed that it came from Voyager." Those ruins could've been abandoned for centuries, overgrown and buried in soil, and only later rediscovered and excavated. It happens all the time. Heck, I read a news item just today about a Maya city
that's just been visited by archaeologists after being abandoned for 1200 years.
