Slow mounting of SSD

[Mte90]

I saw that I have 2 non-allocated space before and after the unique partition, so with gparted I moved everything to remove the first non-allocated and fixed the alignment to cylinders (because before was MiB) but the problem persist.Now the first sector is 63.

[absolut]

please paste the output of    fdisk -l

watch the alignment / start of the sda1 partition

please re-align the partitions using gparted (or other tool) to 2048. this is actually the new default value since some time already.

[Mte90]

before was 2049 but there was the problem so I tried changing the sectors.

[absolut]

a partition starting with 63 or 2049 is not aligned

[Mte90]

How I can align it? On internet I didn't find a tutorial or a tool for that.The old ssd has sector 2049 and didn't have this problems

[unklarer]

For repair of the alignment
My level of knowledge is (I am not all-knowing), it is extensive.     Therefore it is first to consider whether it is not easier to repeat the copying of the plates with gparted (on the again virgin ssd)

I also assume that the old original of sda1 still exists as a backup   

They need:
1. a siduction-live with gparted and parted (some experience with handling is recommended)

Warning: It is extremely important to always select "Align to NOTHING"(Ausrichten an Nichts) in the following operations!
I only found a German manual. The relevant part for Linux starts at: "Get to work."(An die Arbeit)

If the described operations are successful, the siduction will not start on restart. Therefore, the installation of the grub would also have to be rearranged from Live.   

[Mte90]

I already done that with alignment to Cylinder instead MiB for that reason now the first one is 63 as sector.I can try with nothing as alignment but gparted enable to change the alignment if I resize/enlarge a partition and I don't have anymore space for that.

[der_bud]

Changing gparted back to use MiB should do it, because gparted then normally starts after the first MiB. And arithmetically, the first Mebibyte of a disk contains the sectors 0-2047 (given the sector size is the usual 512 bytes)
It should look like this: https://media-cdn.ubuntu-de.org/wiki/attachments/05/21/ssd-gparted.png

Yes is that view and now the sector is 63.I will probably do a new copy with dd of the old ssd and see if the problem happen again.

Unfortunately, he doesn't understand what we keep telling him...
Of course, with dd the problem will persist again with 63.

[Mte90]

I made a new copy with dd, didn't removed the swap and enlarged the partition and now there are no problems.
