How do I get data off a scsi drive that's crashed?

I am unable to rebuild the RAID, possibly two out of three of the hard drives are crashed. I want to know how to get the remaining data off of the SCSI drives.

I tried to find a cable that would enable me to go from scsi to usb or scsi to sata to usb but am unable to find any scsi support for retrieval of data.

The system was built on a raid 5 with 3 hard drives. One hard drive crashed. I replaced it with a new drive. They are hot swappable. But in the process of changing out the drives, it said that all of my drives had been lost. I tried to rebuild the RAID, and another hard drive crashed. I just want to get the data off of the hard drives now, I don't want to rebuild the RAID, I only want to retrieve the data.

Is there a way I can do this with cables or some other method?

thanks!

Your data is hopelessly messed up.  If a rebuild is started and you lose a second drive, then you just won't find any software product available to consumers that will fix this.  You need a data recovery lab and the guys in bunny suits who take HDDs apart.  Expect to pay a minimum of $1000  (realistically it could be $2500 or more).

Sorry

P.S.  Getting the "data off" is half your problem.  You have to do a block level reconstruction of XOR stripes on an array that was partially rebuilt.   Such software costs tens of thousands of dollars and it is not infallible, it has to take into consideration the specific make/model of the controller you use.

You can try a SCSI 80 pin to LVD adapter along with RAID Reconstructor V4.32 by Runtime Software as a last cheap resort.
You would need a SCSI cable and terminator too.

When you lost the other drive ,it could have been a backplane issue and the drive may be somewhat OK.

Up to you to give it a last shot.

Runtime.org will NOT reconstruct raid arrays that have died during partial rebuilds.   Even though you could get a free eval, it is doubtful you will be successful, and you will have to invest in some hardware just to try it.  Disks crash for a reason, and every moment they are powered up risks further damage.

If you want the data back, don't try to do this yourself.  Pay a data recovery firm.  A DIY reconstruction in this situation is high risk of permanent data loss.

>all of my drives had been lost

Sounds like a backplane issue to me.

He could buy a set of adapters and try a rebuild or run a test to see if the drives truly are bad.
Been there ,done that.

As I said ,up to him.

Naah,  we know the first drive failed. We know others went offline and he eventually got a rebuild to start, then a second failed.   His data is gone.  Remember, they're SCSI disks.  They haven't made those disks for years.  Those disks have to be long out of warranty and usable life.

I've had flaky backplanes cause those exact same issues.
>They haven't made those disks for years
They are still making LVD SCSI drives.
Lot's of places still use them.
I had a Dell PE 2600 run for 5 years using them 24x7.
Not one failure.

With SATA, even the WD RE4's are sucky.

I've had a failure rate of about 60% in a 5 year window.
