Sorry, can't help you any further with that then. I guess you'll have to wait for a Mac user, or ask in an apple forum.

BTW, I personally don't think that the file system is to blame anyway - Kindles are known to just act weird at times.

Thanks a lot anyway! I really appreciate you spending time on this.
For me it's just strange that two Kindle 3s and one PW are all behaving like this. Unless I got some kind of Windows virus which doesn't affect Mac but affected all Kindles which are being handled by me all the time.
I thought it had to do with Calibre because it started when I was sending books from Calibre to Kindles. But now all three of them act strange even without Calibre.
Thanks a lot ixtab!

Umm... wait. Did you actually run that umount command? In your quote, it is commented out (that # sign is a comment to the terminal, so it ignores everything that follows).

So did you run umount /dev/disk1s1 (or possibly sudo umount /dev/disk1s1) before the fsck_msdos command?

You can verify what is mounted using the mount command. Try it before and after the umount one...

I tried again with
sudo umount /dev/disk1s1
getting

umount(/Volumes/Kindle): Resource busy -- try 'diskutil unmount'

I don't know if I can run this diskutil unmount what if i unmount whole Mac ?
When I run without sudo I get

umount /dev/disk1s1
umount: unmount(/Volumes/Kindle): Operation not permitted

No worries, you won't.

The command you need is in section 2. It also states

You’ll notice the drive is no longer accessible in Finder, but it will still be visible through diskutil from the command line [...]

which means that the fsck command should succeed afterwards.

Wow! I got

Volume Kindle on disk1s1 unmounted

Then

sudo fsck_msdos /dev/disk1s1
Password:
** /dev/disk1s1
** Phase 1 - Preparing FAT
** Phase 2 - Checking Directories
** Phase 3 - Checking for Orphan Clusters
512 files, 1297568 KiB free (162196 clusters)

Does it even mean anything

It means that there were no errors on the disk (Otherwise it would have told you so). Whether that is good or bad news is up to you to decide - but it does rule out a broken file system as the culprit.

My guess is still the Kindle firmware itself. It is known to choke on some books, for no apparent reason. Unfortunately there is no known fix either

Thank you so much ixtab for all the help, time, effort and guidance
At least I can now relax and not worry that there is something wrong with the files or file system, whatever that is
You are probably right, it's probaly just Kindle itself and I'll just keep converting mobi to mobi before transferring books.
Thanks a lot!!!

No problem, you're welcome. And you learned some new stuff on the way

... if the mobi->mobi conversion does the trick, then yes, it's probably easiest to just stick with it.
