January 30Jan 30 Good evening,I am attempting to set up my first array. I have a brand new Seagate Ironwolf 12tb hdd. I am getting the error "unmountable: wrong or no file system", which I have seen browsing through these forums, but most seem to be people who have already been up and running. When I do attempt to format the disk, it get either 500k, or twice I have gotten 1 million errors. The AI overlords suggested running a "smartctl" command and it returned results that it then deemed a DOA drive. I will attach those results here and also the diagnostics zip. Any help would be much appreciated in either confirming that this disk is in fact DOA, or what step that I am missing.=== START OF INFORMATION SECTION ===Device Model: ST12000NT001Serial Number: ZRT2J1VELU WWN Device Id: 5 000c50 0eafdce3eFirmware Version: EN01User Capacity: 12,000,138,625,024 bytes [12.0 TB]Sector Size: 512 bytes logical/physicalRotation Rate: 7200 rpmDevice is: Not in smartctl database 7.5/6045ATA Version is: ATA8-ACS T13/1699-D revision 4SATA Version is: SATA 3.0, 6.0 Gb/sLocal Time is: Fri Jan 30 14:48:48 2026 PSTSMART support is: Available - device has SMART capability.SMART support is: EnabledRead SMART Data failed: scsi error device not ready=== START OF READ SMART DATA SECTION ===SMART Status command failed: scsi error device not readySMART overall-health self-assessment test result: UNKNOWN!SMART Status, Attributes and Thresholds cannot be read.Read SMART Log Directory failed: scsi error device not readyRead SMART Error Log failed: scsi error device not readyRead SMART Self-test Log failed: scsi error device not readySelective Self-tests/Logging not supportedThe above only provides legacy SMART information - try 'smartctl -x' for more
January 31Jan 31 Community Expert Shutdown. Check disk connections, SATA and power, both ends. Reboot. Post new diagnostics.
January 31Jan 31 Author Thanks so much for the reply. I shutdown, switched to a new SATA cable as well as a new cable from PSU. Ensured both ends were securely plugged in. donda-diagnostics-20260131-0656.zip
January 31Jan 31 Community Expert Drive is not giving a valid SMART report. If you have already swapped both cables, it's like a bad drive.
January 31Jan 31 Author Thanks Jorge! That's what I was afraid of. We're off to a wonderful start here! Thanks again to both of you for the input and help!
