Hi
Recently my 28 disk server lost its raid array and 2 disks seemed to have been damaged. What I would like to know is there any way I can clone the drives individually onto another computer.

I have purchased another SAS controller for one of my old workstations and have it running.

What I would like to do is create a raid 0 and attach the disks individually and clone them using windows xp.

The problem im having is I can connect the disks to the raid controller but the OS isnt picking up the disks in windows itself so can't access them to clone them.

If I set up another Raid using the raid 5 disks will i lose the data on them ?

Any more info just ask, ive searched for answers on this everywhere some help would be great thanks

I'm struggling to see what your goal is. I assume you're trying to recover your data? I don't understand how is cloning drives going to help you achieve this.
When you say you lost two drives, they weren't from the same RAID array were they? If so, all your data is gone unless you had a hot-swap drive which completed its sync before the second drive went.
Perhaps if you can explain why you're trying the clone the drives I could be a little more help.

Yes im trying to save the data. What ive been asked to do is as follows.

1. Set up a recovery computer running Windows with 5 x 2TB hard drives = 10 TB of working space.
2. Remove one or two RAID drives at a time from the server and install them on the recovery computer. Clone them to the 10TB of working space (using there software). Put the drive or drives back in their original positions after cloning. Make sure they go back to their original slots.
3. After all drives have been cloned, follow our procedure to allow us to log on remotely to the recovery computer and analyze the cloned copies of the drives.

Both drives are from the same raid array they are showing as slot 0, sas,unconfigured bad,not responding when i connect them to the raid controller.

OK, this is a bit beyond me. I have a few thoughts I'll throw in, but I suspect you'll need someone with more experience in this area to help you properly. Hopefully someone will come along!

A few thoughts though:
Clone them to the 10TB of working space (using there software)
Click to expand...
If the drives were attached to HW Raid controller, they will not be visible in windows unless you reformat them (and trash the data). You can't use MS software RAID 0 here. You say they've referred to cloning software: you will need specialised software to do this. Whoever's advising you should be able to tell you what you can use. I don't know myself.
Who's asking you to do this? Surely they'd be best to advise you about the specific steps.

Good luck!

The procedure you describe is typical for a data recovery procedure, but i can't see any raid0 involved. They want bit-images of all the old raid-disks on one new raid volume. The software to create this bit-images is obviously provided. What do you need the raid0 for? Did you already create a raid0 on them with the new controller? That would re-initialize the raid5 disk and destroy important data for the data recovery.

No I havent done this purely for the reason you say data will be lost, that the answer I wanted really. I just thought it was the only way to have them drive seen on my OS.

Thanks for your help guys looks like I will need to sort this out with the company doing it.

Here are what you need to do:
Create a recovery RAID5 with 2TB or 3TB HDD - highly recommend using SMP394/SPM394 from DATOptic.com (AMAZONE) drivers-less or PCIE RAID card <-- lots more money have have to deal with drivers etc...

Use Clonezilla to clone your failed RAID's HDD members the RAID

Load R-Studio into your system, you should be able to see /recovery you data
