Some corrupted files in reconstructed raid (0+1) array

[royair]

story goes like that:

once upon a time.... i had x4 1.5tb seagate HDD's configured in a Raid 10 array, and attached to my asus p6t motherboard.

and it gave me a total of 3tb of storage (2 stripes of 1.5tb backuped with another 2 stripes of 1.5 tb)

i then created 2 partitions on it:
- 100 gb (for operating system, windows 7 x64)
- 2653gb (all the rest, for data, movies, project files etc.., configured as GPT drive)


it worked well for 4 months, until one day one of the seagate drives statred clicking (what a surprise...)

i installed "intel matrix storage" to see which one is corrupted. i did saw, but now i cannot remember.

I then took the PC to my local computer store, and asked them to replce the whole Raid array with 1.5tb hdd's of Western

Digital. (which i find more reliable)

what they did was:
taking out 1 seagate drive, swapping with a WD drive and using "intel matrix storage" to "rebuild" the array

they did so to the 4th and 3rd but on the 2nd drive some error happend and windows restarted, and it wasnt able to load again

afterwards. i couldnt get the OS to load. what so ever (tried repairing with windows repair tool)
you would see somthing like: "windows is loading.." and then after a few seconds pc restarted, and again windows is loading

than restarting and so forth.

so i decided to install a new fresh copy of windows 7 x64 on a slave drive i had.
i finshed installing. and now. while windows starting i got a message regarding "D:" "E:" drives (100gb, 2563GB) are

corrupted and need to be checked by CHKDSK.

so windows started scanning D: & E:
windows found alot of "Orphan" files and did somthing to them (can't tell exactly what...)

the whole scanning process was very slow...
so scannig D: (100gb) was quite fast (and it finished successfully)
but scanning E: for errors took almost 2 hrs... so i decied to rebbot computer while CHKDSK in action (i also thought it

might ruin my files in a way, because i'm using RAID and not a standard drive)



after restart. only D: was recognized by windows..
for E: to be recognized i had to use windows "disk management" console, and convert the disk from BASIC to DYNAMIC.

Now both drives were visible (using file explorer) BUT -> files inside were corrupted..
some movies were playable but they stutter and some werent playable at all..
images are partially (meaning you can see only half of it)
.txt files though were readable...

i still have the old seagte drives (actually only 2 out of 3, one of them isnt recognized by windows in any way although

connected). are they usefull?

when i tried to connect them together with the new WD drives i got an error for the RAID controller that they are not members

of the array.

so.. if to sum things up: s
i have 4 questions:

1. what happend to the corrupted files?
2. is there any tool to repair the corrupted files? (i used r-studio and it didnt worked)
3. can i somehow build the old array using the old seagate Drives?
4. is there any tool that MIGHT help in such situation?

To me it's somewhat hard to follow all the events that you are describing. Maybe it's just me, but if you could summarize all the important facts maybe I will be able to follow and give some more advice.

i then created 2 partitions on it:
- 100 gb (for operating system, windows 7 x64)
- 2653gb (all the rest, for data, movies, project files etc.., configured as GPT drive)

Ok, Raid 10 with two partitions, I am with you so far.

I then took the PC to my local computer store, and asked them to replce the whole Raid array with 1.5tb hdd's of Western

Digital. (which i find more reliable)

what they did was:
taking out 1 seagate drive, swapping with a WD drive and using "intel matrix storage" to "rebuild" the array

Ok, they replaced the faulty Seagate drive with the WD and atempted to rebuild the array.
Still following you.

they did so to the 4th and 3rd but on the 2nd drive some error happend and windows restarted, and it wasnt able to load again

Now I am starting to get lost, they did what with the 4th and the 3rd?

while windows starting i got a message regarding "D:" "E:" drives (100gb, 2563GB) are
corrupted and need to be checked by CHKDSK.

Checkdisk is not your friend, this certainly did not help.

so windows started scanning D: & E:
windows found alot of "Orphan" files and did somthing to them (can't tell exactly what...)

Basically it took them and then stored them somewhere else and renamed them to a file with ".CHK" extension. You could try something like UnCHK http://www.ericphelps.com/uncheck/

Now both drives were visible (using file explorer) BUT -> files inside were corrupted..
some movies were playable but they stutter and some werent playable at all..
images are partially (meaning you can see only half of it)
.txt files though were readable...

Sounds like somehow the rebuild was not 100% successful

i still have the old seagate drives (actually only 2 out of 3, one of them isnt recognized by windows in any way although

connected). are they usefull?
when i tried to connect them together with the new WD drives i got an error for the RAID controller that they are not members
of the array.

Possible... I certainly would hang on to the drive. Due to the whole swapping and changing and using one drive and then trying the other and so forth, your Raid is probably in bad shape.
I doubt that any recovery software will help you. If your data is of value then I would recommend sending it to a DR firm.
