    Hello, I have a usb flash drive which I used to store some files from my Mac. When I tried to copy some files from my Galaxy Note by connecting the device to the usb flash drive using a USB Connector from Samsung, I got a message saying that the drive was write protected or something like that. As far as I know, both Mac OS and Android (GB) are unix systems. Anybody knows why I could not copy the files from my Galaxy Note to the usb flash drive? Any solution appreciated. Thanks.

    Mac OS is UNIX yes, but Android is Linux.

    Do you have it formatted for Mac OS or FAT? Just about any OS can read/write FAT.

    I mounted the flash drive to my Mac and checked. It is MS-DOS (FAT32).

    Linux is a unix based operating system so technically speaking the OP was correct.

    If you have files already on the USB drive and the Samsung shows them after connection, then it means the file system is compatible. That would then imply the problem is permission-related when you try to copy. The directory on the USB drive has to be set to 'world writable'.

    You will have to google change permission on USB drive from Mac to see how to do it. I think it is just cmd-i on the directory on the USB drive from the Mac and then making sure 'everyone' has write permission.

    If the problem is at the USB drive level, then I don't know how you can change that, but I'm sure it is possible.

    Here's another thought. I used GParted on my 64GB flash drive, dividing into three partitions. One for Windows 7, one for OSX, and one for Linux. It works great as a shuttle to move files between the various locations at work, home & while on a plane flying to the UK with no online access I can work offline no problem. GParted is fast, free and very flexible. I burned it to disc, then created a .dmg of it.
