Error Occured (0), Computer is unable to startup?

by chipsam93 / June 25, 2012 5:40 AM PDT

When my computer started up today it said that one my hard drives (WDC WD6400AAKS-7) wasn't working properly. My RAID volume says that its status is normal and my other hard drive seems to be working properly.The one not working properly has "Error Occured (0)" under its status. My computer is unable to boot up and keeps going back to the screen with the RAID Volume and Physical Disks, and will shut down shortly after. I have a lot of data that I would like to keep and any help would be appreciated..

I read in your post that 2 out of your 3 disks are fine. So it's only data from that one disk that might be missing. Surely you have a backup of data that you would like to keep?

If not everything is on a backup (that can happen), then boot from a Linux disk and see what of those missing files you can move to an external disk from there.

Tis is RAID 0

It looks from that screen that this is RAID 0.

If so, then all your data is likely lost.

RAID 0 - Two disks working together as one disk. Data is stored bit by bit alternately on the two disks. Read/Write times are faster but if one of the disks fail then all of the data is lost.

RAID 1 - Two disks where data is stored on both disks identically, each disk holds a duplicate of the other disk. Read/Write times are slower than with RAID 0, but if one disk fails then all of the data is still available on the other disk.

If your setup is RAID 0 and if one of the disks has failed, that data is gone.

Always nice to see people ...

that can read a simple screen Grin .

But I think you're right. RAID 0 implies doing a backup. Or let's say: using RAID 0 isn't a reason to NOT do a backup. Of, course, there never is a reason to NOT do a backup.

This might become a rather expensive data recovery by a specialised company like drivesavers.com.

What RAID exactly?

There's 1 through 5.

Why, by the way, do you use RAID? It's rather specialized. Not to be unfriendly, but I would expect people using it know enough of it to be able to take the right steps in case of a hardware error like this.

That's why I don't use it. Luckily, there might be members with the right experience to help you.

twice, both RAID 0. Happy

The first time I was seduced, two SATA disks in my Dell Dimension with XP is still going but it gave me heart failure every time I turned it on in case it failed, and that was with all the backups I needed. I promised myself, never again.

So then I got this Alienware and I got seduced, again. Devil Two SSDs in RAID 0. This one didn't work too well, a story that may be well known here by now.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
