A110RA Posted March 20, 2020 Share Posted March 20, 2020 (edited) Sorry for my ignorance on this one, I am new to unraid. I am running Unraid Version 6.8.3 I have a 4x HDD unraid system, all but one of the HDDs mounted properly. The one shows Unmountable: Unsupported partition layout and will not format when prompted. I have tried utilizing Preclear and Unassigned Devices as other threads have recommended but I have not had any luck. I have also put the HDD in another PC to validate that it works. Thanks for the help! borg-diagnostics-20200320-1311.zip Edited March 20, 2020 by A110RA Quote Link to comment
JorgeB Posted March 20, 2020 Share Posted March 20, 2020 MBR signature writing is failing, both with preclear: Mar 19 16:31:19 Borg preclear_disk_WD-WCC6Y3VJC8PE[15381]: Failed test 1: MBR signature is not valid, byte 0 [10741] != [00000] and likely the same with Unraid, as that's one the reasons it will complain about an invalid partition, it's a strange one but can't see how it can be anything other than the disk, do you have another one you could try on the same port?

A110RA Posted March 20, 2020 Author Share Posted March 20, 2020 I tried another disk and it resulted in the same error. I also switched the port for that drive on the motherboard and got the same error as well. Going to try swapping the SATA cable next as well. Quote Link to comment
A110RA Posted March 21, 2020 Author Share Posted March 21, 2020 Solved it! I connected the drive with a new SATA cable and its own individual power cable, mounted with no issues. Quote Link to comment
