We bought a new 2GB sandisk cruzer to transfer songs from itunes in a 2 year old mac to our new mac (laptops). We were using a sandisk 256MG cruzer. It only held about 50 songs. We thought the 2GB would hold 8 times as many songs (at least 7 times as many) but it doesn't. We can get sometimes 80 and other times a little over a hundred on the 2GB. It will stop accepting files while indicating that aroung 1.3GB to 1.5GB of space remains.
We are mac novices and this is the first time we have used flash drives.
What are we doing wrong or did we get a defective flash drive?
Please help and thanks.

What is the flash drive formatted as?
Does the new mac recognize all 2 GB? If it does, then the old mac probably doesn't recognize flash memory greater than 512 MB.

The flash drive was new out of the package. And the old mac will recognize any size flash drive. We haven't messed with it since we first got it as our daughters boyfriend showed us (well did it for us) how to transfer the files (in under 3 or 4 minutes) though our wireless router. Tech support from india was of no help-go figure

I have had this same problem when trying to convert files made on Vista or office 2007, to a version compatible with XP. In my case the problem is that the files are huge, which is fine because Vista compresses them, but when it is backwards com, to xp they can't be compressed. I don't know if this was any help, because I don't know allot about macs (except I want one.)
