Cf card for lifedrive

Hi everyone, I am new to this forum and apologise if this is the incorrect format.
I love my Palm but I have a problem
I have an issue on converting my Lifedrive to Compact Flash.card to prolong its life.

I have followed the how to on Wiki I used an Apple Mac, purchased Copycatx and a 4 gb SanDisk ExtremeIII which is on the compatibility list of known cards that work...

I used Copycatx to duplicate the Lifedrives Micro drive as per instruction,
Which I saved to my desktop.
I then put the CF card in the card reader but it won’t transfer the image as the volume of the CF card at 3.74 GB is too small for the image at 3.81 GB.

What am I doing wrong?

I have duplicated the Lifedrives micro drive several times and the image volume is always the same at 3.81 GB.

I tried the card straight out the box and later formatted it on FAT32

No Joy!

Could someone point me in the right direction please?

Regards to All

Ted
