yes , i do.. create a 3rd one with what?? all 8 disks?

Are you sure they are correct?

with the software how? i have the two raid 5 in virtual raid from the auto detect , now what do i do?????????

Hello
RAID Probe should fail to detect the parameters, and the service provided by Runtime, will cost you more than the one from us.

Once you have successfully reconstructed the single RAIDs 5, you'll be in the situation to search/find for the parameters of the RAID 0.

Usually the stripe sizes will differ.

well i did find a service that will try to find the raid paras https://www.runtime.org/raidprobe.htm , but i still like to know how to go about reconstructing this raid to get my data back , as no one has given me a understandable answer. i have all 8 drives in a pc now, after finding the correct paras, what a the next STEP BY STEP instructions ?


Thanks

That page shows pictures of the various principles

Finding the parameters is matter of knowledge that professionals won't share.

You may try some automatic tools out there, but they won't help with RAID 50

The only tool you have is the one we have, its name is HEX editor.

There is one freeware which the name is HxD and you'll find it in so many translations. R-Studio too has its built in HEX viewer, but I prefer HxD since the "sectors view" is more effective (but that is my taste and means nothing)

Otherwise, you can forward us the single drives. Given the low fees we have at http://www.RecuperoDatiRAIDFAsTec.it (Italy) it makes sense also if you are outside Europe. You'll talk with me and I'm quite comfortable with English.

ok, that page is not english , so where do i start i reconstruct two raid 5 in a vr then add them to a vr raid 0?

Please have a look on this page http://www.recuperodatiraidfastec.it/re ... -servizio/

Scroll to the end, you'll see RAID 10, Instead than a couple of RAID 1s let's figure out a couple of RAID 5s

That will give you the idea how it is made a RAID 50.

Two RAID 5 are used as "the drives" of a RAID 0

So you need both "the drives" working otherwise the RAID 0 won't reconstruct.

Have you saved all the single drives?

Beware: Without both the RAID 5 full reconstructed , you won't get any data.

so your saying that the raid 5 in layer 1 is gone, and i would select drives 5 thru 8 in order add them to a raid 5 option in the software and try to recover that. and the drives in the frist raid 5 layer 1 drives 1thru 4 i cant do that, they are gone period???

You won't rebuild it if the two drives are both in the same RAID 5 set and you don't recover the last one that went offline.

Anyway, if your data are valuable/precious you'd better find and read my previous posts with warnings and correct practices on how to manage one RAID reconstruction case.

As always
- save a copy/image of every single drive and work with images/copies. REMEMBER your issue may be caused by weary drives and another may die soon or instantly.
- don't copy/image drives with bad SMARTs, instead ask a professional data recovery to image them with proper hardware imaging devices

R-Studio allows to build "RAID of RAIDs" so just follow this path.

Obviously you need to know all the parameters of both the RAID types (RAID 5 and RAID 0)
