Michael Barnes, a 41-year-old convicted kidnapper, had been charged in a Santa Cruz, Calif. court with raping a woman while he was out on parole. In fact, three women -- not just one -- had accused Barnes of rape. But one of the victims' original police interviews was on a DVD that had become unreadable in the time between the interview and the trial, according to the Santa Cruz, Calif. District Attorney's Office.

After the judge in the trial ruled that the victim whose testimony was on the disk could not testify during the trial, prosecutors did not have enough evidence to build a case for multiple counts of rape against Barnes. The victim was not allowed to testify because of disputes over her original testimony, according to Santa Cruz District Attorney Andrew Isaac.

He said police recalled her statements -- the ones on the corrupted DVD -- as being different than what the victim planned to say during the trial, Isaac said. As a result, Barnes' lawyers claimed that the victim's original police interview, as police remembered it, would have been inconsistent with her trial testimony and therefore would be exculpatory evidence "The loss of exculpatory evidence is a bad thing and the judge was inclined to punish us by not letting the witness testify because of the allegation that we'd lost the evidence."

That made recovering the DVD data even more important. Two local data recovery firms had already said the videotaped interview on the DVD was unrecoverable. But by chance, Isaac's parents had a neighbor who was a retired employee. Having heard of Seagate, Isaac decided to contact them about a medium they didn't even manufacture in the hopes they could recover the data.

Seagate's i365 subsidiary has a data recovery service -- Seagate Recovery Services (SRS) -- that took on the job of trying to bring back to life the November 2006 police interview. SRS loaded the DVD into a player, but "there was nothing on DVD.
