1) I'm dump
2) I got 2 x 2TB in RAID 1 (mirroring) with my all precious gay porn. It was running on something like Intel Rapid Storage Technology.
3) I decided to play with BIOS and switch SATA ports from RAID to regular mode
4) stupid intel's chipset didn't remember the RAID configuration when I switched back to RAID mode
5) stupid intel's software/firmware/etc can recreate RAID without "Data will be permanently removed when you create volume. Do you want to continue? Y/N"

Is there good and free soft that can recover my data? Disks are OK, but there are no partition that is recognized by Win.

:( You may have been hit with Intels problem

I know about that intel's screw up. They should ship replacement MB around April. But unfortunately in this case data lost was my own stupidity...

Heard good things about:

http://www.ptdd.com/ (Used to be Partition Table Doctor and used to be good -- now looks like someone bought them so idk)
http://www.cgsecurity.org/wiki/TestDisk

Haven't heard about but looks like it might help:
http://raidlabs.com/raid_recovery/raid_recovery.php

Also, all these look like they offer demo downloads which you can use to see whether it can recognize your data or not -- if it can, then it'll prob. be worth the time trying to find the free / full cost version of the program.

you guys are gods.

Are you sure you cannot manually set the RAID config in BIOS and just remount the partition? This basically happened to me on my wife's PC when I flashed the M/B BIOS, she had a RAID 5 configured as the primary boot partition and the flash reset the storage controller to SATA mode. I crapped my pants a little, but when I went into the BIOS and set it back to RAID it booted right up.

Thanks for help guys! Got the data back - used Recover My Files (http://www.recovermyfiles.com/)

@ RAID recovery via BIOS - apparently it's not working this way on my new MB (it did work on my previous one)...

Anyway conclusion is: F*CK RAID setup for home use. More pain than it's actually worth.

To have kind of reliable backup I set my 2 disks in a regular mode (no-fucking-RAID). Mounted one as a backup drive in Win7, mounted second drive as a folder on the first one and scheduled once a week powershell script that looks like that:
---
$tmpDate = Get-Date
$tmpDate = $tmpDate.AddDays(-8)
$tmpString = Get-Date $tmpDate -format MM-dd-yyyy

xcopy d:\folder1 d:\!backup\folder1 /E /C /Q /H /R /Y /J /I /D:$tmpString
xcopy d:\folder2 d:\!backup\folder2 /E /C /Q /H /R /Y /J /I /D:$tmpString
---
That's for my collection of gay porn + weekly system drive backup via Win7 built-in "Backup and Restore" (I'm surprised, but it works pretty good)
