I spent most of my time using this plugged into my monitor. MacBook Air 13.3” M1 16GB 1TB AppleCare+ PayPal or Local I used this app called iStat Menus to check the battery health and that is what it showed me.my iMac late 2012 randomly restarts by itself There is also a app called Istat that displays lots of info.When I'm waiting for something and there is no network activity I know something's fishy. The disk activity is not that relevant for me, but networking is useful. HDD Clicker – HDD Sound Simulator iStat Menus offer this for modern macOS.The second is Test Empty Space this one writes test files to the remaining free space on your drive - this test is not destructive, but if you do have a fake, then you could lose your data.įakeFlashTest is designed to perform a quick check to verify if a flash memory device is fake (i.e., they have been programmed to lie about their size) it does not check all memory faults.

The first is the Quick Size Test it will check your drive and report the actual capacity and warn if the drive is fake - this test is destructive and the author states that you WILL lose files. But that is not all it can help prevent corruption for example, a 32 GB SD card may only have 4 GB of memory, and once you fill that 4 GB space, it can potentially become corrupted, resulting in a loss of all the data stored.įakeFlashTest includes two tests, and due to the nature of these tests, we strongly recommend backing up all data stored in the test subjects. This is a pretty slick and simple tool for verifying that you have the memory size you paid for. FakeFlashTest is for testing the actual memory size of USB Flash Drives and SD cards.
