I've a 2 disc array Firmtek, E sata. The RAID 0 has failed to mount. I need to recovery, re-build. Can anyone recommend any software solution?

If it's important stuff on it, don't do anything. Power down and give it to a repair company.
 
i've had raids go down and it turned out to be the machine's power supply not the raid/drives. do you have another power supply and other drives to do a test array build? if all works, then you have a bad drive(s)/controller. either way JanneJansson's right on - if it's critical stuff, don't even repower up the drives with meaningful data. hand it to an expert.

though, if you do decide go the route of data recovery yourself, make sure you first create a image of the faulty drive onto a another drive first, don't perform recovery operations on the original drive.

good luck.
 
Just be careful when attempting to recover data yourself.. It's best to just send it in to the professionals if the data is super important. Sometimes, turning the drive on even one more time could kill it, let alone on and off several times in an attempt to run data recovery software on your own. Esp. if it's a head crash. If it's really important, just find a reputable company and hope for the best.

OR...maybe it's just a corrupted directory from too much dragging-and-dropping and trashing large chunks of data. Using Disk Warrior or other data recovery software is part of being a data loader/DIT...along with, of course, knowing how not to frag drives in the first place.
 
Hi Tim,

I have had RAID 0's fail quite often (faker-raid and real raids), even multiple times in one day once, what I normally do with RAID 0's when they fail is recreate the VD with the same settings you used when you created the drive but do not initialize, as long as the drives are healthy this will work.

On a other note you should be using a workstation grade controller with a write back / write through selectable option for your drives, a raid controller with a BBU is HIGHLY RECOMMENDED

As well about software, I was cutting and pasting everything off of a 6tb raid a few weeks ago to a networked computer and one file I thought somehow ended up with a transfer error and somehow did not transfer correctly, but everything was already deleted on the drive, no sweat I loaded up http://ntfsundelete.com/ and checked the file and it was indeed there ;)
