"He said, 'If you would give us $250,000, we would have it done. We don't have the money to analyze the tapes," Barnett testified.
Galanter later assured the trial judge that the tapes had been analyzed.
He also faces questions about what he knew about Simpson's plan, when he knew it, and whether he should have told what he knew to get Simpson off the hook.
"He's a vital witness," said veteran Las Vegas trial lawyer Dayvid Figler. "He has information that no one can share."
Galanter said this week that he wouldn't comment about the hearing until after he testifies.
Las Vegas attorney Michael Cristalli, who has provided television network analysis of the Simpson hearings, said he expected Galanter will say he did his best in Simpson's case.
"He'll say he provided effective representation of Mr. Simpson, that he examined every witness zealously, and that he prepared exhaustively," Cristalli said, "and that there's no evidence to the contrary."
Simpson still maintains that he didn't know anyone in the hotel room had guns, and that he had a right to the items he was after — football mementos, awards, photos and personal items that he said were stolen from him while he was moving out of his Los Angeles home.
The move followed Simpson's "trial of the century" acquittal in the 1994 the slayings of his ex-wife and her friend, and a 1997 civil judgment that ordered him to pay $33.5 million to the estates of Nicole Brown Simpson and Ron Goldman.
"I talked to Yale about it two or three times," Simpson said during his testimony Wednesday. "The overall advice he was giving was, 'You have a right to get your stuff.'"
