Mac OS Extended (Journaled) is the format normally used with the Mac OS.Įnter a name. Selecting a drive will erase all volumes and partitions associated with the drive. Selecting a volume will only erase the individual volume or partition you selected. In Disk Utility’s sidebar, select a volume or a drive. Launch Disk Utility, located at /Applications/Utilities/Disk Utility. If you need any of the information, make sure you have a backup before proceeding. Warning : This process will absolutely remove the data that currently occupies the selected drive. As such, we won’t call out the exact differences, but be aware that what you see in the version of Disk Utility you’re using may not exactly match the images in this guide. The only real difference is the look of the UI. For the most part, the steps in the process are the same for both versions of Disk Utility. Note: There are two versions of Disk Utility commonly in use: OS X Yosemite and earlier, and OS X El Capitan and later. Depending on the choices you make in the secure erase options, there may be a single data write pass, or up to 35 passes with various data patterns to ensure that all the original data is scrambled beyond recovery. (Use the slider to select one of four secure erase options.)ĭisk Utility includes a secure erase option that will not only erase the hard drive’s catalog files, which point to where individual files are stored on the drive, but will also overwrite the actual data on the hard drive with new information.

We’ll cover SSDs a bit later in this guide. Don’t worry, though SSDs can also be wiped, they just require a different technique. They should not, however, be used with any SSD (Solid State Drive), including a Fusion drive, which contains an SSD element. These methods will work for any hard drive you may be using with your Mac. It doesn’t matter if it’s an internal, external, or your Mac’s startup drive using these techniques you can obliterate the contents of the selected drive, making it all but impossible to recover the data. So, if it’s so easy, why the need for this guide? Well, while the process is simple, there are some important considerations to understand that will affect how you erase your Mac’s drive.įirst, we’re going to look at wiping the contents of a hard drive. No matter the reason, wiping a drive is an easy – though sometimes very long – process that just about any Mac user can take care of on their own. Or perhaps you want to wipe an older drive that you’re replacing because it’s too small, or because it has started to show a few errors when you test the drive. It may be because you’re selling or donating your Mac, and you want all your personal information wiped clean from the drive. So once you delete data let your machine idle for a period of time for the TRIM to take effect and run.There may come a time when you want to completely remove all traces of information on your Mac’s drives. The SSD drive controller will reset the drive cells to ones when it determines that drive activity is at a level that will permit doing so without impacting performance to heavily.

When you delete data from an SSD and you are using Windows 7 and up Windows itself will issue a TRIM command to the SSD drive controller. Performing an erase in this manner will limit the amount of writes to the SSD memory cells to the least possible in erasing data and TRIM will reclaim the erased mamory cells which will restore the drives performance to optimum levels.

Issuing the TRIM command resets the cells to ones which marks the cells as free for writes again. When you delete data on an SSD the memory cells are set to zeros. You can securely erase an SSD by simply deleting the data on SSD and then run a TRIM command on the drive. I think Acronis Drive Cleaner is fine to use on a mechanical HDD.
