5. Troubleshooting
5.1. Displayed Capacity Lower Than Advertised
It is normal to observe a slightly lower usable capacity on your device than the advertised value (e.g., 244GB for a 256GB drive). This discrepancy arises because storage manufacturers calculate 1GB as 1,000MB, while computers and operating systems typically read 1GB as 1,024MB.
