Many external hard drives come pre-formatted as NTFS.
Before you begin to use your new external hard drive with Lima, please check that your drive is formatted as NTFS or Ext4 or as 'Mac OS Extended' (aka HFS+).
Note also that Lima only supports HDD formatted with a Partition table.
How to format your drive as HFS+:
- Be sure your drive is plugged to your Mac.
- Launch Disk Utility, located at /Applications/Utilities/
- Current hard drives will display in a list pane on the left side of the Disk Utility window. Hard drives are listed with a generic disk icon, followed by the drive’s size and model.
- Select the hard drive associated.
- Click the ‘Partition’ tab.
- The partition format of your hard drive will be displayed in the Partition Information.
- It should be ‘Mac OS Extended (Journaled)’. If not, you’ll need to reformat it to the Mac OS Extended file system.
- If you have already written any data to the drive, back it up before proceeding to the next step.
- Click the Erase tab along the top of the window.
- From the Format menu, choose Mac OS Extended (Journaled).
- Enter a name for the external hard drive in the Name field.
- Click the Erase button.
- Please do not forget to properly unmount the HDD before you unplug it.
Your HDD is in HFS+ and ready to be used with Lima firmware. Connect it to Lima to restart the installation process.
First, let’s check whether Windows detects the drive when you plug it in. Plug your removable drive into your computer.
Next, open the Disk Management tool. To do so, press Windows Key + R, type diskmgmt.msc into the Run dialog, and press Enter.
You should see your external drive listed in the Disk Management window.
If the drive does appear to be partitioned, it may be partitioned with the wrong file system. For example, you may have formatted the drive with the ext4 file system from Linux or the HFS Plus file system from a Mac. Windows can’t read these file systems. Reformat the drive with the newer NTFS file system.
Note that this will erase all the files on your drive, so you’ll want to copy any important files off of it first — for example, if you formatted the drive on a Linux or Mac computer, take it back to a computer running Linux or Mac and copy your important files off of it before continuing.
To reformat a partition, right-click it, select Format, and select your desired file system.
Eject your hard drive and connect it to Lima to restart the installation process.
