Troubleshooting: Permissions

ERROR: access denied [-5000]

Your login account does not have the right to create a test file on the volume; it is forbidden by the permissions on that volume.

This is not a malfunction or bug. Although DiskTester runs as a user-mode program, it cannot create a test file on a volume when permissions disallow it. Create an admin account and test using that account.

Suggested workarounds

1) If your account is not an administrator account, create one System Preferences => Users, and test using it.

2) If this is not the boot volume (startup volume), do a Get Info on the volume, then check the box Ignore Ownership on This Volume. Be sure to change it back when done, unless you prefer it that way.

3) If neither of those works, most likely an administrator has set up your system this way deliberately. To test, you’ll have to change the permissions. In some cases the Get Info window for the volume will allow you to make the necessary change: you need “Read & Write” permission for your login account on the volume.
