But they were able to pull up records quickly! Too bad about that whole no recovery thing though.

FML.

Good luck with that. Did a drive die? If so, don't waste your time.

I wouldn't bother. Tell the client what an idiot they are and offer to set them up a raid 1 array instead without their data because it's lost.

RAID 0 where the 0 stands for how many files you get back in the event of a failure!

You know, you'd think by now RAID striping would be somewhat standardized for this very reason. Just like any HDD that fails, you won't get all the data back, but we should have enough knowhow and technology in order to piece the salvageable RAID 0 data by now. :(

Yep, this would be my suggestion if the data is mission critical and you have to get it back. Be prepared to pay several thousand dollars, however. We had to send a laptop drive to a data recovery house a few years ago and it was $2500. A RAID config will be much more expensive to recover and you'll need to provide them with a lot of details such as controller model/revision, etc.

half the bits are gone, whats to be done? there are ways to RAID that let you restore data..RAID 0 isnt one of them.

Well the issue is that there is no parity data from which to reconstruct the lost data. RAID 0 simply stripes the data across multiple volumes so therefore, if one volume dies, you have no way to reconstruct the data as it would be guesswork without having parity data for reconstruction purposes.

WoW terminology.

Guffa.


RAID 0 is where data is saved across several disks. Usually people do raid arrays with 2 HDDs. EX: If I save a .txt file, 1/2 of the actual data will be saved on one disk, and the other half on the other. Then when I load it up, it should ideally load faster because both HDD are putting out data. In more useful applications, think of loading 1 big 1gig file. If 1/2 of the data is stored on each drive, and each drive has a 40megabytes/second sustained transfer, you will theoretically load it twice as fast with a RAID0 array of 2 HDDs.

Now the bad part is there is nothing saved on the other drive in case one of them craps out. ie: right here

That is where Raid 5 comes into play. With 3 drives, A , B, C you get similar performance increase, but you also store the parity data on other drives. So drives B,C will contain parity data of A. If A craps out, then the parity data on B&C can be used to quickly reconstruct drive A. Bad part? More drives, more heat, more money, greater chance for drive to fail (3 * probabaility of failure)

YA RAID0 should be illegal these days. HDDs are so cheap it isn't like one has to shell out 400 dolla for that 4.3 gig HDD. If you are going to try to stripe data across several HDDs, FFS make sure you have parity there! Yeah its less storage space, but you won't be a happy camper when your 900 gigabytes of pr0n storage crap out on you
