Formatting the Iomega® HDD External Hard Drive

FAT 32 format: The Iomega HDD External Hard Drive is PC formatted with FAT 32 to give the drive greater exchangeability between different operating systems.

NTFS format: NTFS is the native file system used by Windows® NT, 2000 and XP. If the Iomega drive is formatted in NTFS, it will not be recognized in Windows 98, Me or Mac® OS.

Reformatting the Drive on a PC: To reformat, right click on the drive icon and select Format.

NOTE: Reformatting your Iomega HDD External Hard Drive with a file system other than FAT 32 may make it unreadable on other computer operating systems.

Mac Users: You can read files on a Mac from a FAT 32 formatted drive, however:

  • The drive may mount slower.

  • Files may copy slower.

  • You can improve performance by reformatting on your Mac; however, you will be unable to read the drive on a PC computer without special software.

Reformatting the Drive on a Mac: The default format for Mac is HFS+.

  • OS 9.1: Click Special on the task bar and select Erase Disk.

  • OS X: Select the Disk Utility application; select Applications, then Utilities, then Disk Utility. Select the Erase tab. (Make sure the volume selected is correct.)

Windows 2000, NT, and XP Users:

Iomega FAT32 Formatter software: If the Iomega HDD External Hard Drive has been formatted with an NTFS file system, it may be unreadable on Windows 95, 98, ME, or Mac OS.
