Problem with my HDD and FS's after upgrade and cloning the HDD

[James Brown-17]

Hi all,
I use the Debian Lenny AMD64 on my laptop Acer TravelMate 3043.
After upgrading from my old HDD 120GB to 500GB and cloning the first to
the last, I have the next problem:
sudo fdisk -l

Disk /dev/sda: 500 GB, 500105249280 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda3           53728       60801    56813872    c  FAT32 LBA

Some people tell me that the "Partition x does not end on cylinder
boundary" is not serious problem and advise me to do not call attention
to that.
But some other people tell my FS's can crash through that and reccomend
me to reinstall my system at all.
What can you advice me with that?

It doesn't matter.  Some OSs (like DOS) would not work with partitions
that weren't cylinder aligned, but every OS these days uses LBA instead
and doesn't actually care about cylinders at all.

Try fdisk -l -u.  As long as the start and end work out without overlap,
the filesystems are going to be just fine.  sda4 is what contains
sda5-sda10, so sda4 should contain all of those, meaning overlap with
sda5-10 is expected.

Very thanks.
I have tried fdisk -l -u and I have had the next :
~$ sudo fdisk -l -u
[sudo] password for igor:

So, there are no overlaps, but there are some gaps.

I think you have cloned your disk with an external Desktop-PC, right?
And the desktop PC has another hardware than your laptop!
I've hat a similar problem 3 weeks ago with one of my customers,
I cloned a disk of a desktop
PC (Suse 8.2) by hand with another desktop PC  (Suse 10.2). I had the
a simlar error (I don't remember the exactly error text) and
Suse 8.2 didn't find the partitions! I use always ext3 as filesystem.
So I cloned again the disk in the Suse 8.2 machine and all went well,
no errors!

An idea: take parted or acronis Disk Director, etc, boot your Laptop
with one of these tools (e.g. take knoppix on CD/DVD) and resize your
partitions a little bit! But leave your disk in your latop! parted
or acronis, .. should make correct boundaries while resizing.

Let me know if you have success.

Feel free top forward/quote my posting to debian-laptop@...,
I'm not subscribed.

The gaps make sense.

The reason is the way extended partitions work.  An extended partition
contains a partition table with one primary partition and another extended
partition.  The primary partition is your logical partitions, and the
extended partition is the space of the remaining logical partitions.

So your layout appears to be:

partition                           start                  end
----(partition table)                   0                   62
sda1(primary)                          63              8177084
sda2(primary)                     8177085             83762909
sda4(extended)                   83762910            863124254
 sda4(partition table)           83762910             83762972
 sda5(primary)                   83762973             84453704
 ----(extended)                  84453705            863124254
  ----(partition table)          84453705             84453767
  sda6(primary)                  84453768             94221224
  ----(extended)                 94221225            863124254
   ----(partition table)         94221225             94221287
   sda7(primary)                 94221288            100084949
   ----(extended)               100084950            863124254
    ----(partition table)       100084950            100085012
    sda8(primary)               100085013            102799934
    ----(extended)              102799935            863124254
     ----(partition table)      102799935            102799997
     sda9(primary)              102799998            103587119
     ----(extended)             103587120            863124254
      ----(partition table)     103587120            103587182
      sda10(primary)            103587183            863124254
sda3(primary)                   863124255            976768064

Looks fine to me.
