This could be a result of your having formatted the card. You should never, never, never have to format a new CF card and if you don't properly format it, you will lose space. Did you reformat it using the same file format (FAT or FAT32) as it was originally formatted? ----- Original Message ----- From: "Scott Duck" <sduck@xxxxxxxxx> To: "Book Port Discuss" <bookport@xxxxxxxxxxxxx> Sent: Monday, March 28, 2005 10:07 AM Subject: [bookport] Copying Files to New Card Good morning everyone, On Friday, I purchased a 512MB Sandisk Compact Flash Card. I then proceeded to copy the contents of the old card to the new card, as follows. With the old card inserted, I connected the BP. I went into Windows Explorer and selected drive F, which is my BP drive. In folder options, I turned on show hidden files. I selected the entire contents of the root directory of the BP and copied it to the clipboard. I then went to a new directory on my hard drive, which had been created for this, and pasted the files that I had just selected into that directory. I disconnected the BP, inserted the new card, formatted the card, and reconnected the BP. I selected all of the files that I had just copied to my hard drive and copied them to the clipboard. I went back to the F drive and pasted the files. Now, here is the problem. With the old card inserted, the BP transfer software shows 122MB total, 3MB free. If you do the math, that means that 119MB are used. With the new card inserted, the transfer software shows 488MB total, 385MB free, which means that 103MB are used. All of my files appear to be on the new card and I haven't had any trouble reading any of them yet but I haven't tried to read all of them. Everything seams to be working fine but it appears that about 16MB got lost along the way. I am puzzled. Please help! Thanks, Scott
