Issues with Sandisk U3 2GB USB Thumbdrive

My MBP has 2 USB slots, when i plug in my U3 into any of the slots, the drive is recognised by MBP. But if i were to transfer files (usually happens to large files such as those 50MB and above) from U3 to MBP, the transfer status just hang and i cannot eject the drive. So must force it to quite by manually unplugging the U3.

Then i would normally plug it in again for few times and i can transfer the files. This does not happend when transfer frm MBP to U3. And this does not happen to other my other Sandisk Cruzer 1GB thumbdrive.

From what i observed if i plug in the drive long enough (let say 5 min) then only initiate file transfer from U3 to MBP, usually it will not fail.

BTW, using the same U3 on Windows does not give any issue. And i've formatted my U3 a few times as FAT32 format.

The following is the error log:
