Prepare A Hard Drive Software Resulted InWhen you select the drive device, the partition tab will appear. If the drive is going to be used only with your Mac and with other Macs, then consider using Apple's Mac OS X Extended (Journaled) format, and only use FAT32 if you intend to use the drive with a Windows system. Additional tools from third-party manufacturers may lead to compatibility problems, as was recently seen when incompatible drive management software resulted in data loss for a number of people who had upgraded to OS X Mavericks.Because of this, if the drive you have purchased is a special RAID array, then you may have to use the manufacturer's setup however, if it is a single-drive device, then before using it be sure to format it using Disk Utility in OS X. For one, unless the drive uses a special multidisk RAID setup, OS X already comes with all the necessary tools for managing the drive. While these may be convenient, they are not the most recommended approach to managing the drive. Sometimes drives will come with special drive management software on them that will give you options for partitioning the drive and backing up your files to it.Generally a format of the drive in this manner is all that is needed however, some people may wish to test drives further to make sure the media does not contain any bad blocks or other errors beyond the scope of the drive's formatting.For most in-depth testing of drives, a third-party tool like Drive Genius or Tech Tool Pro can be used, but Disk Utility does support one option, which is to use the Secure Erase option to write zeros to the disk surface. Click the Options button and ensure "GUID" is selected as the partition scheme.When this is done, the disk should unmount and then remount with the new formatting settings, and now be ready for use. Select "1 Partition" from the drop-down menu (or more, if you have specific need for more than one volume).When you select a new partition layout from the drop-down menu, each new partition will be formatted to Mac OS Extended (Journaled) by default, but be sure to double-check this by selecting each in the partition diagram and then choosing the format for it. Choose the "Partition" tab that appears. Select the drive device in the list of devices, which is the item above any storage volumes on the drive, and which may show the manufacturer name, media size, and so on.Secure Erase and other similar options that test each storage block of a device may take a number of hours to complete, but it reduces the number of potential problems with the drive.Questions?

This will cause each available data block to be accessed and written to, and if one is bad then the disk will allocate a spare block in its place and ensure that the logically writable storage space is available for use.![]()
