Re: XPS 420 SATA RAID and drive failing

Sounds like an interesting solution. Did you just call Dell's XPS support and get the engineer to call? Was it the Indian or US/Canada office that arranged it?

Re: XPS 420 SATA RAID and drive failing

I oroginally logged a cal about 3 weeks ago, but then I contacted Dell support via email saying that the problem was getting worse.  We got a phone call from one of the Dell support teams in India saying that the engineer would call to swap the drives.

 

I don't know if it makes any difference but the machine was bought via my company.

Re: XPS 420 SATA RAID and drive failing

I've tried logging support calls twice via e-mail and they seem to be ignored. Dell did call me last friday and promised a call back from a manager, but nothing! Their support is abysmal for this product.

I supppose I'll have to call them again and arrange something. Think I'll speak to Customer Services at the same time and complain.

Re: XPS 420 SATA RAID and drive failing

I spoke to Dell (India) today and they are sending me 2 new Seagate drives which I will install myself. So I presume it's a case of taking the 2 drives out and replacing them with the new ones, then use the Dell DVD to re-install Vista.

Re: XPS 420 SATA RAID and drive failing

I ended up having to re-install the disks myself as the Dell engineer installed them as RAID 0 (something that I can't understand!) so I ended up deleting that array, then putting one of the original (failing) disks back in the machine on port 0.  The machine booted up found that disk, and hence the original array, but with an unassigned disk (one of the new ones) this I assigned to the array and then booted into Vista from the original disk, so no settings where lost, and let the software get on with rebuilding the array.

 

Then I shut down the machine, took the original disk out, and put the other new one in, and repeated the process, so I ended up with the 2 new disks in the machine but with the original install - so I didn't have to re-install any software.

 

The actual physical installation of the disks is a quick 2 minute job, and the array re-build took about 1 to 2 hours each time - but at least I could walk away and let it get on with it rather than having to re-install and setup everything again.

 

BTW What is happening to your old drives, are Dell going to collect them off you?

 

Hope the above helps.

Re: XPS 420 SATA RAID and drive failing

Thanks for the info, but I don't see how it's possible to re-build the array from a RAID 0 stripe. If it were a mirrored setup, then yes, the software should be able to re-construct the array from the original disk.

For a RAID 0 stripe, data is spread across both disks, so losing one would mean the entire array is lost.

Is your PC stable with the new Seagate drives?

Dell are going to arrange to collect the drives next week when I have tested the new ones.

Re: XPS 420 SATA RAID and drive failing

The new drives have been in the machine for a week now and it has been fine so far, however when the machine first arrived it was OK for a couple of weeks until the drives started failing.

You are, of course, correct about not being able to rebuild a RAID 0 array in the way that I described.

Re: XPS 420 SATA RAID and drive failing

Dell have just delivered the 2 new Seagate drives. I'm going to do a fresh installation on them later today but I am not going to use the RAID 0.

Re: XPS 420 SATA RAID and drive failing

I'd recommend RAID 1, at least then if one of the drives fails again you don't loose the whole array and all your data - that's my thinking anyway!

Re: XPS 420 SATA RAID and drive failing

Yes, a mirror woould be good, but I'm not convinced that it will be reliable under Vista and the Intel Matrix.
