Hello everyone, This is primarily addressed to the folks at APH. I started drafting this message Friday night. Note: I am using a Lexar 1 GB card. OK, since my last message, the unit has been locking up on the same file each time. I tried sending the files one at a time, and got the same results. This time, I was able to write down the following additional BP errors: Card insertion error; ......; saving voice recording Firmware Error Conditioning Y#N RZV at line number 29698. Press the 0 key to reset BookPort. Preceding this, the transfer software forze in the middle of sending this one specific file, and when I hit Cancel, reported that the flash card was full; it is not. I never removed or reinserted the card. Also, the 0 key would not reset the BP. I had to remove the batteries to force a reset. The firmware conditioning error occurred more than once, but has not occurred since Friday, though much additional testing was done. What I have found, with extensive testing over the weekend, is that the card seems to have become partially corrupt. I can fit over 600 MB on the card, but wants I get down to about 363 MB free, nothing else will go on the card. BP Transfer reports a card full condition, and CF readers report that the device is not ready. I have tried using the BP and the PC to reformat the card. Once, I even tried reformatting it as a FAT32 (then sent files to it from the PC's card reader), and got the same results. I've tried running ScanDisk and the BP Transfer's Fix Errors utility on the card, but to no avail. This card is just a couple of weeks old, so I can't imagine it would have gone bad. Can anyone at APH provide insight into the error message above, and what may have possibly happened? I don't want to put money into another 1 GB card until I at least have an idea if I did something wrong, or what might have happened. I am happy to answer any questions to help clarify the situation. Thanks, Cheryl
