About file system formats
NTFS: since it is the native file system for Windows, volumes created in NTFS are read and write with
computers running Windows. Mac OS can read NTFS volumes but cannot native ly write to them.
Mac OS Extended (HFS+): the native hard drive file system for Mac. Windows cannot native ly read or write
to HFS+ (journaled) hard drives.
exFAT: generally compatible with Mac and Windows. exFAT is not a journaled file system which means it can
be more susceptible to data corruption when errors occur or the drive is not disconnected prope rly from
the computer.
FAT32: compatible with Mac and Windows. Howeve r, FAT32 is a legacy file system de signed for low
capacity hard drives and it is not recommended for modern hard drives or operating systems. A FAT32
partition can reach up to 32GB when formatted on a Windows PC.
How to choose the file system format
Use NTFS if:
…the storage device is connected to Windows PCs.
Use HFS+ if:
…the storage device is connected to Macs.
You can use exFAT if:
…the storage device is shared between Mac and Windows computers.
Use FAT32 if:
…the storage device is connected to olde r Windows and Mac computers. FAT32 is not recommende d for
modern ope rating systems and computers.

Q: Is your hard drive listed next to an unusual icon?
A: Windows Device Manager usually provides information about failures with pe ripherals. While the Device
Manager can assist with troubleshooting most problems, it may not display the exact cause or provide a

An unusual icon next to the hard drive can reveal a problem. For example, instead of the normal icon based
on the type of device, it has an exclamation point, question mark or an X. Right click this icon and then
choose Properties. The Ge neral tab provides a potential reason why the device is not working as e xpected.
