Formatting and Partitioning
Standard LaCie storage devices will prompt you to run LaCie Setup Assistant when they are first connected to a PC or Mac. LaCie Setup Assistant helps you to quickly format the storage device according to your needs. Please read the information below carefully if you:
- Abort LaCie Setup Assistant while it is formatting.
- Wish to reformat your storage device after LaCie Setup Assistant has successfully completed.
- Own a LaCie storage device that does not feature Setup Assistant.
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 natively write to them.
Mac OS Extended (HFS+): the native hard drive file system for Mac. Windows cannot natively 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 properly from the computer.
FAT32: compatible with Mac and Windows. However, FAT32 is a legacy file system designed 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 older Windows and Mac computers. FAT32 is not recommended for modern operating systems and computers.
The steps below help you format and partition a storage device.
Caution: Formatting erases everything on the storage device. LaCie highly recommends that you back up all data on your storage device before performing the steps below. LaCie is not responsible for any data lost due to formatting, partitioning or using a LaCie storage device.
Note: Refer to your operating system's documentation for more information on formatting and partitioning storage devices.
