Hi@ster,
Steps:
1. Before formatting the hard disk, you need to execute it under the system's attempt: disk offline;
2. Then enter diag diagnosis and try to execute: reset disk;
3. After the format command is executed, the system does not prompt the format status and progress after you press enter. You need to execute the command: display disk information to view it;
Formatting the hard drive takes a long time: a 300G hard drive is expected to last 2-3 hours. The larger the hard drive, the longer it takes to format it.
E.g:
[USG6650-diagnose] display disk information
Disk information:
-------------------------------------------------- -----------------------
Filesystem Status: Formatting
Filesystem Total: 0MB
Filesystem Free: 0MB
DiskId: 0
DiskVendor: SEAGATE
