Hello,

I tired booting my macbook pro up this evening and got the grey screen with a circle and line through it. I am running two 512gb SSD's in a Raid 0 configuration using and OptiBay. I was able to boot into an old external Lion boot disk and ran a smart check on the internal drives. I got this error.

Now, I have a data backup as of two weeks ago, so I have all of my important data. Is the disk done for? This is an almost brand new 512 gb SSD, so I am hoping it is not dead.

Any help is greatly appreciated.

Thanks,
David

Yes, the disk is done. Contact the manufacturer to get an RMA - they're usually good about such things. Early failures like this are unfortunately not uncommon with SSDs.

Ok thanks. Also, I do a large amount of file transfers and HD video encoding. Is this a problem for SSD's and will it cause a higher failure rate or does it really matter?

Thanks,
David

What makes you say that disk is done? I normally assume these sorts of errors are just because they are set up as RAID. RAID is not tremendously reliable for boot drives, especially if you don't have a hardware RAID controller.

[P]

Well, that's what it is saying - that the RAID setup is there, and that one drive is missing. As I said, this is not so uncommon with SSDs.

I just pulled both drives out. One will mount externally and one will not.

[Waragainstsleep]

Sounds like it is indeed borked. Technical term.

With one dead there's nothing useful on the other.

I wouldn't RAID0 boot drives. Most operations on your computer are limited by access times and not throughput – and a RAID0 has slightly slower access times than single »drives«.
