error code 43

when i try to transfer files from my macbook air to the expand flash drive i get this error message:
The operation can’t be completed because one or more required items can’t be found.
(Error code -43)
What is this? What do i need to do?

Have you tried googling it?

There appears to be a large number of discussions/articles on the subject. :wink:

I bought two SanDisk 16gb to make two backups for my imac.  The first one went fine and I unplugged it  I got an error message that the disk was not removed properly, which I ignored.  I plugged in the second Sandisk and tried to make an identical backup, but kept getting the “error code 43” message.  I plugged the first one in to make certain my backups were there, and they were fine.  Before I unplugged it, I right clicked and clicked on “Eject Disk”.  When I plugged the second one in and tried a backup again, it worked just fine.
