[resolved] yet another - mdadm raid1 ntfs-3g question

[nightamaury]

Hello,

This is my situation

/dev/sda with boot, swap, linux partition OK

/dev/sdb with NTFS partition windows installed
/dev/sdc with nothing on it (or strange old erroneous data)

A8N SLI NVIDIA fakeraid...


A long time ago, while I was running windows, I had /dev/sdb and /dev/sdc mirrored with nvidia RAID1.
I then removed /dev/sdc and put it in back several month later. For some stupid, reason I did dd if=/dev/sdb of=/dev/sdc which is wrong for raid1. I then began to do dd if=/dev/zero of=/dev/sdc but I didn't let it end.

I'm now running gentoo and wondering what I should do:

• A complete dd if=/dev/zero of=/dev/sdc so as to make my machine believe /dev/sdc is a whole new disk and let it rebuild it from /dev/sdb data
  
• An other dd if=/dev/sdb of=/dev/sdc
  

I know using dmraid with Linux is not clean. I wonder if I can use mdadm raid with NTFS-3G and still can dual boot with windows on this same "NTFS-3G mdadm mounted" partition ?


Thank you very much for your help.

I don't think Windows has native support for reading mdadm style partitions. I think your best bet would be with a hardware controller, either as a add-on card or on a motherboard chipset. This site describes how you can setup the two OS's using there own software. Linux can read the windows raid with some work, but not the other way around.

What ever you do make sure you back up your data first.

Thank you for your answer.

That's what I was looking for
