The drive is preformatted with FAT32, NTFS is also possible.
A small folder with Tools is already stored on the disk, including a tool for formatting. The data is erased when formatting, so you should save the folder if you want to keep the tool previously on the computer, if necessary, this can also download on the homepage and at Transcend.
The formatted as NTFS file system disk is recognized easily by my ASUS TransformerPad with Android 4.4.
The tools include a small backup tool, with which the backup can be restored.
You can create different backup scenarios and then choose accordingly for the backup to not always to create everything as a copy. This one must of course not be done on the tool, it makes things easier maintenance.
