How to mount existing Intel RAID ISM (RAID 0) device on Linux?

in flag

I have two 1TB drives from 2011 that I need to get the data off of ASAP.

Both of these drives are working and were configured as RAID 0 under a Windows Vista machine. Both drives are plugged into my Fedora machine, and I need to mount them as a RAID device so I can pull data off.

The first drive is shown as /dev/sda and the second drive is /dev/sdb. The machine I was using configured some part of the RAID array in BIOS, where my current machine cannot perform such an operation.

Is there a way to mount these drives on my machine to access the data?

By running the command "sudo mdadm -E /dev/sda /dev/sdb" this is the output:

mdadm: /dev/sda is not attached to Intel(R) RAID controller.
mdadm: /dev/sda is not attached to Intel(R) RAID controller.
mdadm: /dev/sdb is not attached to Intel(R) RAID controller.
mdadm: /dev/sdb is not attached to Intel(R) RAID controller.
/dev/sda:

As you can see by the output, the drives are both alive, and the previous raid configuration is recognized, however I cannot mount this.

After issuing the command "sudo IMSM_NO_PLATFORM=1 mdadm --assemble --verbose /dev/md0 /dev/sda /dev/sdb" I get this output:

mdadm: looking for devices for /dev/md0
mdadm: /dev/sda is identified as a member of /dev/md0, slot -1.
mdadm: /dev/sdb is identified as a member of /dev/md0, slot -1.
mdadm: added /dev/sdb to /dev/md0 as -1
mdadm: added /dev/sda to /dev/md0 as -1
mdadm: Container /dev/md0 has been assembled with 2 drives

and finally after trying to mount it with "sudo mount /dev/md0 /mnt", I get the following output:

mount: /mnt: can't read superblock on /dev/md0.

after using the GUI tool gnome-disks, /dev/md0 shows up but says "Block device is empty"

I am probably going about mounting these incorrectly, and I need help.

If this data is important, engage a professional data recovery firm immediately. You have already done several things which put your data at risk and could possibly have destroyed it, such as not copying the drives and working with the copies.

Seconding @MichaelHampton. I wouldn't want to attach these without a proper RAID controller in between that could import foreign RAID configurations, and then only in read only to ensure I didn't scramble the data. RAID might save the data, but it can be pretty unforgiving.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
