Installation from scratch

mm.strange the numbers are mutiples of 8 lets try for sda6,7 and 8 the trick we did with sda5, let partiton start 8 cylinders from last one (as all of them are in extended partition)
(I know some cylinders are now unused.)
so
sda5 start 209 end 312
sda6 start 321 end 328
sda7 start 337 end 400
sda8 start 409 end 243200

@fvdw

To avoid losing these cylinders, we should ask to paros to tell us, by changing the default unit used (cylinder ->sector), which first number of sector is proposed after the creation of sda4 when he wants create sda5. If an offset is proposed as in the first partition (64 instead of 63) and also when he wants create sda6 to confirm a possible offset every time if you create an additional logical partition.

I think we should create the table using only sectors: for example there is no need to start at cylinder 9, but only starting at sector 64 (as proposed by fdisk) and ensure that the partition size given sector is divisible by 8.

Can you please give the instructions step by step.
Shall I create partition 1, 2, 3, 4 using cylinder and starting with 9, and then change to sectors and write down the proposed number when creating partition 5?

You have the bad luck of being the first :crazy to install the firmware on a disk "AF" (you must have this logo on the disc).

As we have no this disk type, we can not make tests ourselves.

What I proposed:

-Use the last instructions to create partitions (parameter settings in cylinders).
But after creating the partition sda 4
- switch in sector mode, command u
- Make a print, command p (and post the output)
- Begin creating the partition sda5, command 'n' , and note the sector number proposed and cancel the order (cntrl C)

redo fdisk, resume creating partitions upto sda5 (parameter settings in cylinders)
After creating the partition sda5, do again:
- Make a switch to sector command u
- Make a print command p (and post the output)
- Begin creating this time of the partition sda6, command 'n' and note the sector number proposed and cancel the order (cntrl C).

redo fdisk again (...) and make all the partition table like you are used now to make :whistle with the last fvdw instructions, to check if these settings work well (and you will lose 40 cylinders)

So, much work...but maybe after your tests, we will be able to propose you new settings without losing fully these cylinders.

Sorry, but there are so many tables so I just want to make shore that I am using the correct one.

Is it this one I shall use?
Partition 1 start 9 end 72
partition 2 start 73 end 136
partition 3 start 137 en 200
partition 4 start 201 end 243200
partition 5 start 201 end 304
partition 6 start 305 end 312
partition 7 start 313 en 376
partition 8 start 377 end 243200

Or is it a combined version (1-4 as one page 4 and 5-8 as at page 5) like this:
Partition 1 start 9 end 72
partition 2 start 73 end 136
partition 3 start 137 en 200
partition 4 start 201 end 243200
Partition 5 start 209 end 312
Partition 6 start 321 end 328
Partition 7 start 337 end 400
Partition 8 start 409 end 243200

[Jocko]

Yes, the last fvdw partition table is :
Partition 1 start 9 end 72
partition 2 start 73 end 136
partition 3 start 137 en 200
partition 4 start 201 end 243200
Partition 5 start 209 end 312
Partition 6 start 321 end 328
Partition 7 start 337 end 400
Partition 8 start 409 end 243200

Here we go (I have larger images if needed) :-D

Thanks parso,

it is not very readable but I think I can use your images.

With the last fvdw partition table, your error messages desappeared ? (I think so) If yes, this is good news but you lost 160GB.

I think I recognize the problem with the logical partitions, fdisk normally shift to a value of one cylinder, as it has 63 sectors, the partition is not aligned to the first cluster. should be a minimum offset of 64 sectors (or more but divisible by 8)

If you agree I will calculate a partition table with sectors

Yes, there is no errors with this table, but as you say, -160gb...
If you could create a table suitable for my disk, I would be very pleased!

[Jocko]

Ok,

I send you the table in the early evening, (I have to eat! and for French is a sacred time :-D ).

This will be a test, and I hope it will work...
