Topic: resized NTFS partition and now can't open the partition

Hi,

I was installing Windows 7 last night and I used the latest 5.0.3 live cd to resize an ntfs partition on my drive down from the whole drive to around 300GB, and then created a new partition in the remaining space to install the OS.

However i (somehow?) completely missed the giant red warning about using the latest live cd and it has broken my old partition so i can't read it anymore. Any help would be appreciated!

Richard

Re: resized NTFS partition and now can't open the partition

Which partition is experiencing the error?

Would you be able to provide the output from the following two commands?

fdisk -l -u

where one of the options is a lower case "L" and not the number one.

parted /path-to-your-device unit s print

where /path-to-your-device is something like /dev/sda.

Re: resized NTFS partition and now can't open the partition

I assume the problem is with partition sda1 since you said you only had one partition on the drive.  If the problem is with a different partition then you will need to change the parameters in the capture commands.


Next we will need copies of the Master Boot Record and the NTFS Partition Boot Record.

You can capture the Master Boot Record in a file with the following command:

NOTE:  Be extra careful to type this command in properly, otherwise loss of data could result.

dd if=/dev/sda of=sda-richardwyke.mbr bs=512 count=1

where sda-richardwyke.mbr is the name of the file that will need to be uploaded.


You can capture the NTFS Partition Boot Record in a file with the following command:

NOTE:  Be extra careful to type this command in properly, otherwise loss of data could result.

dd if=/dev/sda of=sda1-richardwyke.pbr bs=512 count=1 skip=63

where sda1-richardwyke.pbr is the name of the file that will need to be uploaded.


Then upload these files to a media sharing site, such as mediafire, and post the link to these files in this forum post.
