How to reformat or partition your external hard disk drive

Bookmark and Share

Reformatting destroys all data on the drive. Back up any data that you want to keep before you reformat the drive.

To use the Disk Management application
1. Click Start, click Run, type compmgmt.msc, and then click OK.
2. In the console tree, click Disk Management. The Disk Management window appears. Your discs and volumes are displayed.
3. Right-click on the drive you want to reformat (or partition) and use the options provided to reformat or partition the drive. To use the DiscWizard for Windows application Launch the DiscWizard for Windows application in the Files directory on the Seagate Disc Utility CD, and follow the easy-to-use, on-screen instructions.

1. Open Disk Utility, which is located in Applications/Utilities. In Mac OS 9, this utility is named Drive Setup.
2. Select the disc that you want to reformat and/or partition in the left column. Be sure to select the new drive, and not an existing drive that may contain data, because reformatting and/or partitioning erases all data on the selected drive.
3. Click Partition if you want to partition your drive, or click Erase to reformat the drive as one volume. Partitioning is not required; if you select Partition, continue to the next step. For Erase, you’re done!
4. Choose the number of partitions from the Volume Scheme pop-up menu. Click each partition and enter a name, select a format, and enter a size for each partition. (You can also drag the partitions to change the size.) Select the Mac OS Extended format for each partition unless you have a specific need to select any other available Volume Format option.
5. Click Partition, and then click Partition again. Your drive appears on your desktop with the volume label(s) you entered in the steps above. If you elected to partition the drive to create two or more volumes, each volume will have a drive icon and label.
