I am facing an issue with fdisk (gnu-fdisk): fdisk doesn't allow me to enter the right sector values. When I enter the values mentionned in the pdf and accept modifications proposed by fdiskI get senseless partition values:

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

Can you give me a workaround or some softwart that can do the job?

Hi pleuk,

You don't use the right values !
See in the Howtodo

Code: Select all

/dev/sdb1   1      32   257008+  83 Linux
/dev/sdb2  33      64   257040   83 Linux
/dev/sdb3  65      96   257040   82 Linux swap
/dev/sdb4  97  121601    9xxxx+   5 Extended
/dev/sdb5  97     144   385528+  83 Linux
/dev/sdb6 145     145     8001   83 Linux
/dev/sdb7 146     178   257040   83 Linux
/dev/sdb8 179  121601   9xxxxx   83 Linux

For example, partition1 ends to 32 and partition2 starts with the value 33

In your table last cylinder of the partition n = first cylinder of partition n+1 !!!

Thanks for replying.
I know the values are wrong but it's what I get when I enter the good values.
Clearly speaking whent I enter "32" for the end of partition 1 FDISK gives ma a "33" ! If I enter "33" I get "32" but the workaround doesnt work for the next patitions.
Maybe something is wrong whit my disk (cluster size or some low level thing???)
If someone can help !

Yes I read too quickly your original post.

For me, you should try to use another version of fdisk and see if you have the same behavior : for example by using bootable CD

Hi !

I think the problem is the same as mine... Try with the '-u=cylinders' option when you use fdisk :
sudo fdisk -u=cylinders /dev/sdb

The default unit for recent fdisk is sector and the HowTo uses cylinders unit...

PS : Sorry for my english... I'm french and need to improve it (And you don't listen my accent :hail)!

when fdisk is running you cangive the command "u" (without the quotes) to toggle between sectors and cylinders
