How big is a sector fdisk?
How big is a sector fdisk?
Each track is divided into 63 sectors. Each sector contains 512 bytes of data.
How do I find the sector size?
This answer is severely outdated.
- Run msinfo32 in command line that should popup a GUI window called “System Information”
- In the left pane select “System Summary->Components->Storage->Disks”. This should load info of all drives in the right pane.
- Find your desired drive and check the value for “Bytes/Sector”.
What is physical sector size?
The physical sector size is what the hard drive actually reads and writes in; the logical sector size is what you can ask it to read or write (and I believe what logical block addresses are in). The physical block size is always equal to or larger than the logical one.
What is the optimal sector size for a Linux file system?
Sector size (logical/physical): 512 bytes / 4096 bytes On current linux distributions, programs (that should care about the optimal sector size) like mkfs.xfs will pick the optimal sector size by default (e.g. 4096 bytes). But you can also explicitly specify it via an option, for instance: # mkfs.xfs -f -s size=4096 /dev/sda
What is the optimal sector size for SDA in Linux?
# fdisk -l /dev/sda [..] Sector size (logical/physical): 512 bytes / 4096 bytes On current linux distributions, programs (that should care about the optimal sector size) like mkfs.xfs will pick the optimal sector size by default (e.g. 4096 bytes).

Is 4096k a good size for a file?
So, while a 4096K logical sector size is awesome for large files, for a normal everyday use PC, it’s just a bunch of 0’s. Now, with that said, there is the option of storing data in the MFT itself when it comes to data smaller than the logical sector size.
How do I change the sector size of my HDD?
To switch the HDD sector size, you would first need to verify that your HDD supports the reconfiguration of the Logical Sector Size. Changing the Logical Sector Size will most likely make all existing data on the disk unusable, requiring you to completely repartition the disk and recreate any filesystems from scratch.
