Disk Utility: "Partition is misaligned by 1024 bytes..."
location: ubuntuforums.com - date: February 10, 2015
I'm planning to steal some of my Windows 7 partition to increase size of my Ubuntu on my dual-boot as I explained here (just waiting til I can buy some more internet allowance so I can download a Live iso - my internet access is via tethered smartphone). While waiting for my piggy bank to fill, I had a look at my system with Disk Utility, and found my Ubuntu partition is "misaligned by 1024 bytes" which may result in very poor performance." (Screenshot attached)
The laptop is giving less-than-optimal performance, but this may very well be because I smashed the screen and fed coffee to the keyboard. I use an external monitor and usb keyboard and mouse now, so my laptop is a desktop... but who knows what other destruction I have caused the machine's innards? Anyway, I'd like to fix this "misalignment" issue - but not if it means I have to reformat and lose my music/video/other collection (yes, backup backup backup... but it would be such a pain - plus the &qu

Is there way to change partition size with disk utility? I got 200 gb non system partition (just for documents) and wonna to make it 190 gb to install backtrack 5 on other 10 gb.
"Disk Utility" WARNING: The partition is misaligned by 1024 bytes....

Disk Utility suggests that I repartition.
How I got to this point:
I did a complete, fresh install of Ubuntu 10.10 Maverick 64-bit on my 1.0TB hard disk accepting all the installer's defaults.
If I repartition, I guess I should re-install, right? (I have no data yet so that would not matter.)
My question is, I guess, how do I prevent 'ground-hog day'? I don't want this to happen again.
"Disk Utility" WARNING: The partition is misaligned... System76style

Just got my new laptop and I have few questions about partitioning. I have not modified my partitions but get a warning from Disk Utility. I eventually want to add partitions but this warning is making me a tad bit nervous.
Disk Utility: “Warning: The partition is misaligned by 2048 bytes. This may result in very poor performance. Repartitioning is suggested.”
My laptop is a System76 Gazelle Professional (gazp6) running Ubuntu 11.10 64-bit. The hard disk is a Seagate Model: ATA ST9750420AS (scsi) and one of the 'Advanced Format' drives (4kB sectors).
Two partitions exist: sda1 and sda2/5, the latter being the extended and logical partition for swap and the former being the system files.
Being that this is the way the laptop shipped, I'm unsure if I have a real problem but would like to know how to proceed to shrink my primary partition, expand my extended partition, and then create more logical partitions for a dedicated /home as well as other partitions for other dist

Disk Utility, mdadm raid 5 misaligned
location: ubuntuforums.com - date: May 3, 2010
Ok so 3x1.5tb hds in RAID 5.
Not hawt after upgrading to 10.4, I went to disk utility and noticed this, well it could have happened before and never noticed but anyway.
It says under the raid array, WARNING: The partition is misaligned by 48128 bytes. This may result in very poor performance. Repartitioning is suggested.
So does that mean I have to delete the RAID array, and do it again? That is the worst solution I have ever heard ever.
And how do I know this won't happen again?
Thanks in advance.

3TB drives partition not aligned according to Disk Utility
location: ubuntuforums.com - date: May 4, 2012
I bought a pair of 3TB SATA drives to replace a pair of 1.5TB drives in my music server. Whether I partition it (EXT4) with GParted or Disk Utility (Palimpsest) I am told (by Disk Utility) that my partition is not aligned:
WARNING: The partition is misaligned by 3072 bytes. This may result in very poor performance. Repartitioning is suggested.
Currently I have only installed one of them and there is no data on it, so now is an excellent time to resolve this matter.
What am I supposed to do?
(FYI: I used GUID.)
3TB disk drive partition misaligned by 3072 bytes? (Ubuntu)
location: linuxquestions.com - date: June 7, 2014
Hello all. (Linux novice here).
I've added a brand-new Seagate 3TB disk drive (Model ATAST3000DM001-1CH166) to my dual-boot Ubunut 12.04 / Windows 8 machine. I did the initial format on the Windows side (NTFS), and all seems well there.
The drive functions on the Ubuntu side as well, and properly mounts and reads/writes file.
However, the Ubuntu disk management program gives a warning that the partition is misaligned by 3072 bytes, which may result in very poor performance and recommends re-partitioning the drive. I've tried using the Format Drive tool within the disk management program to format the drive in various ways (EXT4, NTFS), but the warning message remains.
See the attached screen capture.
Is there a way to properly set up this drive in Ubunut Linux?
Disk utility shows the first partition labeled as sdb2
location: linuxquestions.com - date: July 8, 2011
Before doing a clonezilla project I opened
Disk utility shows the first partition labeled as sdb2, then second partition as sdb1is this normal?
I will add that this is a windows drive, but I wanted to back it up before installing debian to it.
How will the disk partition labeling affect partition naming in debian?
