Successfully Managed to Remove RAID0


Recommended Posts

Hi Guys,

I've experienced a problem on my PC recently.

I have a Dell XPS420 and towards the end of last summer the PC started to crash, screen would go black, and one of the fans sped up inside really quickly, until i rebooted, and the fan would come on slowly again, and then eventually the same thing would reoccur.

I removed the side panel, blew out the inside with compressed air, downloaded the latest driver for my Geforce 8600GT video card and as soon as i downloaded the driver the fan speed sped up without it crashing, i reformatted the hard drive, reinstalled Windows, and all was fine until two days ago.

The same thing happened again two days ago, first the operating system locked up, and the Windows bar at the bottom of the desk top screen changed colour (went white) then the screen started locking up, then it went blank, the fan sped up, i tried downloading the driver for the graphics card again, but didn't work this time.

I therefore purchased a new video card yesterday, the Geforce 630 with a massive fan ontop of it, installed that last night, but the operating system was playing up big time, i couldn't install the drivers for the video card, tried the enclosed CD Rom, even online, everything i tried to do on the Pc wouldn't work, even right clicking on the desk top and choosing 'personalise' came up with errors, Google Chrome wouldn't open, i couldn't even right click 'my computer' to try and get into Device Manager, as it told me that Windows Explorer could not open or something to that effect!

The whole thing was running slow, even though i'm running Vista on a Quad Core Intel with 4GB Ram (i know Vista can only use 3GB).

It was even doing a religious CHKDSK on every reboot!

So, i went for a fresh install of Windows, using the installation CD, all sorted i thought, until it loaded for the first time and told me straight away on the login screen it came up with some error box telling me that the user account control file or something is corrupt! This was a fresh install!

So, i'm now thinking hard drive problems, so thought about replacing the hard drives and removing the dreaded RAID 0 whlist i was at it, thought i would experiment with the old drives whilst removing the RAID0 and then if i can do it, then buy 2 x new hard drives once done.

Managed to remove the RAID0 volume from within the RAID BIOS screen (CTRL & I) and then set the hard drives to ATA in BIOS, then reformatted both hard drives using the Vista installation CD, and all reinstalled fine and i now have 2 x 300GB separate hard drives showing in Windows Explorer (happy days !)

The hard drives and the PC all seem to be working brilliantly now, but do you reckon i could still have bad hard drives?

I'm running a CHKDSK now but it seems to be taking a lot longer now they are no longer RAID0.....

Also, its been so long since i've not had RAID0 set up, how would you use the 2 seperate hard drives?

I was thinking having 1 of the drives just for the operating system and program files, and the other hard drive for my media, i have about 180GB of media consisting of photos, videos etc., and if i wanted to replace that hard drive for media with a 1TB drive would that be easy enough to do if i keep it seperate to the program and operating system drive?

"The hard drives and the PC all seem to be working brilliantly now, but do you reckon i could still have bad hard drives?"

Yes. If something is going wrong with your RAID then either you have crappy drives or crappy controlling hardware/software. If you remove the RAID and still get problems either one or both of the hard drives are bad and need to be RMA'd. Run the manufacturer's utility to check the condition of the drives.

Guess What? Just as well i havent loaded anything onto these drives yet, as Windows is starting to mess up again.

I started to load MS Office 2007 from a CD, it was taking forever to open one of the files on the CD, the progress bar at the top of the screen kept creeping along slowly, and then it froze, i tried a Ctrl Al Del and it said its not responding....

Then it came up with something about System Login Security failed........

Do you reckon its the drives? Have i done anything wrong do you think?

They are Western Digital Drives, just about to see if i can download there diagnostics checker.

Edit: Would welcome as much input and assistance as i can get, as can't really afford another PC, and this was a great PC for a good few years.

Check the SMART on those drives, that should be the first thing you should do. Also see if the event viewer has any disk error / warnings on it. Also RAID 0? really?

Hi Mate, i'm not all that clued up, what does that mean?

Yes they were def RAID 0.

I've just tried to download the Western Digital disk checker here

http://support.wdc.com/product/download.asp?groupid=606&sid=3

Extract, run, and it comes up with 'unable to execute file' 'Create process failed code 740, the requested operation requires elevation?

Just managed to run Western Digital Data Lifeguard Diagnostics - DLGDIAG for Windows and run a quick test on both drives and it came back as a Pass.

Ran a quick Smart test on each drive and it placed a green tick in each drive saying 'Smart Status' Pass.

Any other ideas what could be wrong?

run as administrator that app (right click on the exe and chose "run as administrator"); also try HD Tune http://www.hdtune.com/download.html to view the SMART table on the disks; S.M.A.R.T. or Self-Monitoring, Analysis and Reporting Technology, is a technology that every modern HDD has; it holds lots of info about the HDD, like temperature, spin time, reallocated sectors count and more; you can see lots of attributes here http://en.wikipedia.org/wiki/S.M.A.R.T.#Known_ATA_S.M.A.R.T._attributes. Also there are lots of programs that check the SMART table and report in a easy way if the HDD is good or is damaged.

Ok so ive now peeformed Extended tests on both drives and they said they completed succesfully using the Western Digital diag tool that I posted above and the SMART has passed.

So they cant be damaged then?

Anything else can be slowing it down and causing hangs and error messages after a reformat?

Shall I start another thread?

Take the drive(s) out, try them in radically different hardware and see if the same problem occurs.

If no problem -> your motherboard or drive controller (if not on the motherboard) or RAM or PSU is dodgy.

If same problem -> your drives are failing.

... also try HD Tune http://www.hdtune.com/download.html to view the SMART table on the disks; S.M.A.R.T. or Self-Monitoring, Analysis and Reporting Technology,

I'd second this over running the SMART app from Western Digital. I had a 2TB WD disk causing issues in windows. Windows logs indicated it had issues writing to the drive (a lot or retries). Running the WD app showed the SMART as a pass. Running HDtune showed a fail. I returned the drive to WD for RMA.

Thanks N k And Jason, ill try that Hd Tune on the drives.

Also, re swapping out the drives into another pc is it as simple as disconnecting from my faulty pc and installing into another? I have an old Packard Bell running XP, if I swap the drive out to the XP machine will that XP Machine boot straight into Vista (which is on the troublesome pc) ?

HI Guys,

Might have had a breakthrough, although a confusing one at that....

As mentioned above, i performed a quick test via Western Digital dianostic test and each drive returned fine.

Then last night before going to bed, i did a longer 'extended' test and Drive 1 (operating system) (think the operating systems on that one as don't know if WD number them differently) and when i got up this morning it past, then when i went out to work this morning i started the 'extended' test on Drive 2, and just got in from work and it said 'stopped - too many bad sectors'!!!

But its on Drive No.2 and i'm almost sure its Drive 1 that the operating system is installed on...

I'm just about to download HDTune and run that as suggested,

Bad sectors on any drive can cause crashes, especially if they send bad data to the disk controller. If you open event viewer and look under system you'll probably see some error messages indicated that there were paging errors and / or delayed write failures.

Downloaded HDTune and could only test 1 drive as was only showing 1 in the drop down box, run the test on that drive and it found something cant now remember what as I was confused as wanted to know why it wouldnt show the other drive so went into explorer and the other drive isnt even showing now!!

To summarise, both drives were showing in explorer as I remember saving a notepad file to the d drive (drive 2) once I removed the raid 0 to make sure it worked.

So I then restarted the pc to see if it would show and the pc wont even boot now!

Came up with an error in the flash/dos screen that no boot device can be found or something.

Could that WD diagnostic test have killed the drive completely?

Edit said 'drive 1 not found serial ata sata1 Alert! Failed to detect one or more drives during post strike f1 key to continue f2 to run the setup utlity press f5 to run onboard diagnostics.

So well and truly knackered them drives!

Can those diagnostic tools finish off a poorly drive?

Yes they can but only really if the drive is inheritly bad anyway, i.e. running a diagnostic isn't going to make a drive that fine have mostly bad sectors.

Either RMA the drives if they're within warranty or sell the spares if not or whatnot.

And don't listen to people moaning about RAID0, it does what it's meant to. If you store all your mega important files on a RAID0 then yes, you're an idiot, but if you use RAID0 for what it's meant for (a boot OS drive only with applications/games) then that's fine.

it's not moaning, RAID 0 is fine for what is meant for (performance); the problem is i never saw a RAID 0 configuration purposely made with the perception of the disadvantages in mind, ever; all the RAID 0 configs is saw was in the aftermath of a single HDD failure (meaning the array was gone), with important data going bye bye; much safer is RAID 10.

lol it's not moaning :rofl:

RAID 10 needs 4 drives and you might as well RAID 5/6 them instead, plus this is all being done using your system CPU, so it'll run much slower than a software RAID 0.

I've got a RAID 0 setup for my arch box, it's not my main device and if the drive/array failed then yeah I'd lose some things but nothing of importance.

    • Micron reveals AI companies are spending billions to lock up its memory years in advance by Karthik Mudaliar The demand for more memory is far from over, and Micron is turning the AI-driven memory shortage into a much more predictable business. The company has revealed that it has signed 16 strategic supply agreements backed by roughly $22 billion in customer deposits and other financial commitments. The contracts cover DRAM and NAND deliveries over several years, with some running through 2030. With the AI boom, demand for high-bandwidth memory (HBM) has grown so quickly that large customers are now prepared to help finance future production in exchange for a guaranteed supply. According to Micron’s latest financial results, the company received commitments worth about $22 billion across its new agreements. Around $18 billion is expected to arrive as cash deposits, while the rest will come through other financial arrangements. Micron says the agreements could generate approximately $100 billion in future contracted obligations. They cover around 20% of its expected DRAM shipments and one-third of its NAND shipments during their respective terms. It should be noted that although AI infrastructure is the main force behind the current shortage, not all 16 agreements with Micron involve AI companies. Micron said the customers also include consumer electronics and automotive businesses, two sectors that increasingly compete with data centers for the same manufacturing capacity. HBM is consuming an increasing share of that supply. Unlike conventional desktop or server RAM, HBM stacks multiple memory dies vertically and places them close to an AI accelerator. This gives GPUs and other AI chips access to data at much higher speeds, but it also requires more complicated manufacturing and packaging. Micron says its 12-layer HBM4 memory is now shipping in high volume for a lead customer, with samples also supplied to other companies. The chipmaker has already generated more than $1 billion in HBM4 revenue and says the product is ramping twice as quickly as its earlier HBM3E generation. Samsung has similarly warned that the memory shortage could continue into 2027 and beyond. Consumer memory companies have also had to address sharp increases in DDR5 pricing, suggesting the effects are already reaching beyond the data center. For consumers, that could mean the AI memory crunch lasts longer than expected, even as manufacturers invest heavily in new production.

    • Microsoft updates Visual Studio Code with chat cost tracking and multi-agent chats by Paul Hill Microsoft has just launched Visual Studio Code 1.126, its latest weekly release. This time, the company has focused on letting you see the total cost of chat sessions to spot expensive conversations; enabling multiple chats per session that run side-by-side in one agent host Copilot session; and letting you browse new folders safely in restricted mode. We have now reached the stage where free AI in IDEs is coming to an end. To help you keep track of your costs, VS Code now lets you see the entire cost of a chat session, rather than just individual turns. This should give you more transparency about which sessions consume the most credits, so you can better manage your usage over time and spend less. For those of you using the Agents window, you know it is possible to run and manage multiple agent sessions at once. In this update, a Copilot session started from an agent host can hold several chats at once. Explaining how this feature works, Microsoft writes: Finally, from this update forward, Microsoft will remove the pop-up when opening an untrusted folder. When you open a new folder now, it will automatically open in Restricted Mode. You will see a banner that lets you manage the trust level of the folder. Microsoft has made this change so that it’s easier to start inspecting code without giving it trust right away. If you have VS Code, you can check for updates within the app now to get this new version. Otherwise, you can download it from the Visual Studio Code website.
    • Anthropic accuses Alibaba of using 25,000 fake accounts to copy Claude's capabilities by Karthik Mudaliar Anthropic has accused Alibaba of using nearly 25,000 fraudulent accounts to extract capabilities from Claude on a huge scale. According to a report from Reuters, Anthropic told US lawmakers that operators linked to Alibaba and the company’s Qwen AI team generated 28.8 million exchanges with Claude between April 22 and June 5, 2026. That is a lot of Claude conversations, but Anthropic says this was not ordinary chatbot use. The company believes the accounts were part of a coordinated effort to collect answers that could help train or improve rival AI systems. The alleged campaign reportedly focused on some of Claude’s most valuable skills, including software development, multi-step reasoning, and agentic tasks. In practical terms, that means getting an AI model to plan and complete work across several stages rather than simply answering a single question. This is called 'distillation,' where AI companies use outputs from a larger model to train a smaller and cheaper one. The smaller model learns to imitate useful parts of the more capable system without needing the same amount of computing power. The distillation process isn't automatically suspicious, but the problem comes when one company gathers another provider's outputs without permission and at an industrial scale. Also, this does not mean Alibaba obtained Claude’s source code, model weights, or original training data. Instead, Anthropic claims the accounts repeatedly asked Claude carefully designed questions and collected the answers. Those answers could then be used as training material for another model. Anthropic has made similar accusations against DeepSeek, Moonshot AI, and MiniMax earlier this year. As Neowin previously reported, Anthropic said those three companies collectively generated more than 16 million Claude exchanges through roughly 24,000 accounts. Anthropic says the new campaign produced almost twice as many exchanges in a matter of weeks. Anthropic reportedly told lawmakers that the campaign could help Chinese AI developers approach the capabilities of its Mythos Preview model. Mythos is focused on advanced cybersecurity work, including finding and exploiting complex software vulnerabilities. via Reuters | Photo via DepositPhotos.com
