Hi All, |

I am resizing a Windows partition to get some space for Gentoo. I |
| 4 |
noticed that when gparted finished and I rebooted the machine there is |
| 5 |
a blank unallocated space in front of the Windows 7 partition, shown |
| 6 |
below as 6.33MB: |

Also, when I used gparted to create a new extended partition over the |
| 26 |
431G free space at the end of the disk I ended up with a similar small |
| 27 |
unallocated space in front of it. This is something I have observed |
| 28 |
happening recently on 3 laptops that I have worked on, i.e. resizing |
| 29 |
or creating a new partition inevitably creates a small blank partition |
| 30 |
in front of it. |
| 31 |
|
| 32 |
Looking at the sectors table I see this: |

I am not sure what the asterisks are for after the last sector on the |
| 47 |
second and third partitions. |
| 48 |
|
| 49 |
Could this empty space jump be related to gparted somehow shifting the |
| 50 |
start of a partition to make it align with a particular sector as per |
| 51 |
previous thread on the 4k sector topic? |
| 52 |
|
| 53 |
Should I do anything about it, or just run with it and let gparted |
| 54 |
align what it wants to align as part of the partitioning process? |
