Windows 7: raid 0 windows ntfs gpt volume

raid 0 windows ntfs gpt volume

Hello,

Setup mb asus p6t6 ich10r (raid controller)
2 x vertex 30GB
2 x seagate 1.5TB in ( motherboards controller fakeraid ) raid 0 array Volume1 = 1 GPT partition with 1 windows dynamic simple volume ntfs formated (just 1 big ~3TB partition for storage created on a previous install of Windows 7)

Reinstall Window 7 on a vertex

Problem:
After reinstall the raid array is not recognized by Windows 7 it asks me to initialize the disk (which is a raid volume).
I say yes, then asks to create MBR or GPT i say GPT.
But then it says the disk is unallocated and wants me to create a new dynamic volume, i say simple volume.
But now is asking to format... and here i stopped, with out formating to new ntfs.

Questions:
Is there a way to recuperate / restore / reinstate / recover / rescue / rebuild .... the old dynamic ntfs simple volume ?
So that i could access the data without having to use a data recuperation program for 3TB of data.

Will a quick ntfs format and a scan-disk make that possible?

Thanks

Hello MasBlaMan,

I think it is a big mistake to use any RAID for storage without having backups I also think that as you have started to make changes in windows that it may well be too late to save your files, but I may be wrong. Formatting it would only make matters worse so I would not do that.
You could try booting a live linux cd and see if it is possible to retrieve your data that way, but you would need somewhere to put it ie an external drive.

I'm sorry, but how does telling me that RAID is BAD is helpful ?

If I had backups I would have no problem and... , but wait what if the backup got broken and the 3rd one to, and there was a storm and all my GIANT BACKUP FACILITY is gone, and a black hole swallowed it all up (wait thats not possible time dilatation and stuff...)? What then!!!

Ok, sorry again, its just to say that maybe I cant afford a backup and the configuration worked flawlessly for over 2 years... until i messed up so im looking for the easiest and fastest / cheapest solution out of this.

With Linux is even harder because you need to explain to it that this is a mobo fake raid and for that you need special tools (dm-raid, kpartx) and on top of that you have windows's and diskpart's GPT partition with "basic" or "simple" "volume" to.

I tried testdisk from Ubuntu and did not find the right partition after 24+ hours... but thats for another forum....

I personally would stay away from RAID & dynamic partition, as it seems to more problems than it is worth.

If you have a External HD, you could try copy & paste your data.
Copy & Paste - in Windows Recovery Console
than copy & paste your data back.

May be try Rescue kit:

You have answered your own question in a somewhat humorous way, I am not telling you that RAID is bad as I use it my self, but it is extremely risky, and the point is that a failure is normally fatal for your files as they are spread over more drives which often makes recovery impossible. I know there is no 100% security but to have no backup for whatever reason just leads to disappointment. and that is my helpful point!

TestDisk was the solution.
But thanks for the "good" advice and support.

And yes i will still be a bad boy and keep my raid0 without a backup

good luck ya'all
