This microSD card is reported as:</p> <pre><code># diskutil info /dev/disk8 Device Identifier: disk8 Device Node: /dev/disk8 Whole: Yes Part of Whole: disk8 Device / Media Name: SD USB_3_0 Read Volume Name: Not applicable (no file system) Mounted: Not applicable (no file system) File System: None Content (IOContent): None OS Can Be Installed: No Media Type: Generic Protocol: USB SMART Status: Not Supported Total Size: 127.1 GB (127103139840 Bytes) (exactly 248248320 512-Byte-Units) Volume Free Space: Not applicable (no file system) Device Block Size: 512 Bytes Read-Only Media: No Read-Only Volume: Not applicable (no file system) Device Location: External Removable Media: Yes Media Removal: Software-Activated Virtual: No OS 9 Drivers: No Low Level Format: Not supported </code></pre> <p>So, the microSD has 248,248,320 sectors.</p>
