There is absolutely no way to determine the point at which a CF card may fail. I've had one card that failed after about three or four months of use. On the other hand, I had cards that withstood extremely heavy repeated use that never failed. No electromechanical device can ever be said to be absolutely fail-safe. ----- Original Message ----- From: "Gosselin, Louis" <LGosselin@xxxxxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Wednesday, September 14, 2005 9:02 AM Subject: [bookport] Re: POSSIBLE FILESYSTEM HANDLING BUG IN BOOKPORT F IRMWARE 2.X? I'm shocked. I thought, after reading the Library of Congress's endorsement of flashcard technology, that their usefulness and durability was virtually limitless. Can someone clue me in? Is there an expected life expectancy for flashcards? Is there an expected number of times one may be re-written before it fails? Do you know how many times that is--roughly, of course?

That's a good point, but in my case, the flash card is less than a month old, so I hardly think I've used the cycle count up. -Brian On Sep 13, 3:03pm, Chris Hill wrote: } Subject: [bookport] Re: POSSIBLE FILESYSTEM HANDLING BUG IN BOOKPORT FIRMW } Could be a bug with bookport.
