I created a 10 GB ext2 formatted TrueCrypt volume under Linux. I installed Ext2Fsd 0.51 & TrueCrypt 7.1a on my Windows 7 machine. I mounted the drive & proceeded to copy over several GB of data. After about 1.5 GB transferred I began to get "No space left on device" errors, although Windows still showed that plenty of space is available. I mounted the volume under Linux and confirm that it works fine.
