T1 File System
Your T1 is formatted using the exFAT file system by default to support both Windows OS and Mac OS.
Please note that there may be restrictions on reading or writing data when using your T1 on both
Windows OS and Mac OS. If you plan to only use the T1 on a single OS, it is recommended that you
format your T1 using the appropriate file system for the OS.
Important Information:

When using exFAT on both operating systems, data writing may become locked and you may
only be able to read data. If such a problem occurs, you can restore write access by following the
instructions below.
1
Mac OS: Connect your T1 to your Mac OS again, and then eject the volume (T1).
2
Windows OS: In the notification window that appears when write access is disabled, click Scan
and Fix. Then run Check Disk (CHKDSK).
If you closed Check Disk, you can run Check Disk by selecting the drive
right-click
choose
Properties
choose Error-Checking under the Tools tab.
*
When your T1 is connected to a device other than a PC, usage may be restricted depending
on the file system supported by the OS of the device and the file system of the data stored on
your T1. Please check the device's supported file systems before use. Please note that if T1 is
formatted using a different file system in order to enable use with a particular device, all user
data stored on your T1 will be deleted during formatting. Once formatted, user data cannot be
recovered.

Capacity of T1
When your T1 is connected to a PC, the capacity displayed on the system (Windows Explorer on
Windows OS) may vary from the capacity marked on the product, depending on the drive's file system,
partitioning and computer system.
*
The capacity marked on the product is calculated according to the following standard:
1MB = 1,000,000bytes / 1GB=1,000,000,000bytes / 1TB=1,000,000,000,000bytes
