Partition 2 does not start on physical sector boundary

Question

I Installed Ubuntu erasing Windows couple of days ago. Now Ubuntu is using the entire HDD.

When I run fdisk -l result shows something like:

.........
Disk /dev/ram15: 64 MiB, 67108864 bytes, 131072 sectors`
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes


Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0xa1767c2b

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1  *         2048 960894975 960892928 458.2G 83 Linux
/dev/sda2       960897022 976771071  15874050   7.6G  5 Extended
/dev/sda5       960897024 976771071  15874048   7.6G 82 Linux swap / Solaris`

Partition 2 does not start on physical sector boundary.

Does this Extended partition bad for performance or HDD? And How can I fix it? I read some article but I don't understand what really need to do. If possible please give me some suggestion like on some article I've seen something like that 'Use Gparted to move 512to 4k....' type suggestion. I tried using gparted, I can do anything. There are only two options 'Manage flags and Information'

I use Lenovo ThinkPad.

Thanks for your help.

Solution

sda2 is the extended partition which holds the logical partition sda5. You never read from or write to sda2, you read from or write to sda5 and sda5 appears perfectly aligned. So there won't be any negative effect for your disc-performance, leave it as it is.
