(I still can use it with Apple, but not yet with Linux).

Would it be possible to run chkdsk driveletter: /r using windows on your FAT32 drive?
Might be possible that your file system is faulty.
Before you run chkdsk, you should backup your data first.
Chkdsk is a utility to have a try to repair a file system but not to recover data.
Under Win7 / Vista you should run it as administrator.
Works like;
Please check your drive letter!

Go to Start.
Write cmd in search programs and files.
Press both, the Ctrl-key and Shift and press enter.
Confirm to proceed your command prompt as administrator.
At the prompt, write;
chkdsk driveletter: /r
If there are any questions about the volume, please confirm it.
It may take some time, because the check is an exhaustive check.
If chkdsk hangs or get interrupted, please let me know.

Yesterday I did a backup of my data, and then ran chkdsk; although it said no errors had been found, now Ubuntu does mount the disk! Well, I'm not complaining

I will send a donation right now. Thank you very much, Fiona!

Thank you for your feedback!
I'll set your topic as solved.
