L0rdRaiden Posted March 30, 2018 Share Posted March 30, 2018 I have folders in the SSD (Cache) witha size of 500MB but a disk size of 1.4GB. In windows it appears fine. I guess is because of the 4k format? isn't it better a lower one? why is this the default? If I want to convert the disk do I have to re-format it? or can I just convert it? Link to comment
John_M Posted March 31, 2018 Share Posted March 31, 2018 I don't really understand what you are asking. When you say "the 4k format" are you talking about the change from 512-byte sectors to 4096-byte sectors, known as Advanced Format, or are you talking about the size of an empty directory being 4096 bytes, or are you talking about something completely different?

The sector size I guess, it says 4k aligned, is this the sector size? Link to comment
bonienl Posted March 31, 2018 Share Posted March 31, 2018 Go to the Main page and click on the disk you want to view. See the section "Identify", it will show the sector size in use by that disk. Link to comment
L0rdRaiden Posted March 31, 2018 Author Share Posted March 31, 2018 It says 512bytes logical, 4096 bytes physical for the HD The SSD cache is 512bytes logical/physical Should I change it? Link to comment
bonienl Posted March 31, 2018 Share Posted March 31, 2018 This tells how the disk is operating, can't be changed. For the OS the sector size is reported as 512B in both cases. Link to comment

Is making everything to use more space, can't be changed doing a backup and reformating the disk? Is the setting to fix it available in the unraid interface? Link to comment
bonienl Posted March 31, 2018 Share Posted March 31, 2018 There is nothing wrong with the HD settings. Most modern hard disks have a physical sector size of 4K, but report 512B to keep backwards compability with the OS. Perhaps you are looking at sparse files. Btw the 4K alignment you are referring to is for the MBR, has nothing to do with file sizes. Link to comment
