October 29, 2025Oct 29 As title sugest i'm not putting the biggest disk in parity, But looking at the screenshot the NVME (new parity disk) is the same size, and the partition sector is actualy bigger. What am I doing wrong? Or wat am I overlooking? Edited October 29, 2025Oct 29 by Wesselvdb
October 30, 2025Oct 30 Community Expert Unraid creates a slightly smaller partition for SSDs. This is for performance reasons, so they cannot be used to replace an HDD of the same capacity.
October 30, 2025Oct 30 Author So unraid creates a new partion, starting at 2048 if i'm correct. If i shrink the biggest disk partition by at least 2048 - 64 I should be fine correct?
October 30, 2025Oct 30 Author OK changing size makes unraid not recognise the "biggest disk" as the same disk....If i empty that disk, change the size and add it as a new disk. will it remember that is has a slightly smaller sector count? of does that get overwritten agian once I add it?

October 30, 2025Oct 30 Community Expert If added as part of a new array with an existing partition layout, Unraid will keep it, for any other situation, like a rebuild or a disk added to an existing array, Unraid will create the standard partition layout.
October 30, 2025Oct 30 Author OK I Emptied the disk, did a fresh format on it, took a bit more than 2000 sectors away. Configured the array as a new array with the SSD as parity, added the Edited disk as a new disk and all existing on the original location. After starting unraid wanted to format the "new" disk again. And it works!
