Question: RAID capability Does anyone know if this machine has RAID capability?
Document: I replaced the system drive with a Seagate 2TB hybrid SSHD. This one upgrade has impacted the machine in a significant way. I'd say its right up there with the RAM upgrade and the CPU swap. Everything is faster. Sadly, I wouldn't say the machine is fast now, just faster. :)  I recommend anyone still squeezing every unit of utility out of their machines to go do it.
It's not a RAID configuration, but a Window Clustering system that does the same thing to protect data so even if 1 drive fails, the data is duplicated across remaining drives.Over the years, the computers in our house have collected different sets of photos from different cameras in a way that I'll never be able to reconcile.
Most HP and Dell Servers sound like a jet engine when they first start up, and the quiet down to a dull humming....not something I would want in my family room. And even if you do choose to use Windows Server 2003 with either hardware or software RAID 1, you have to mirror the entire drive, whereas the Home Server lets you pick the folders that you want to mirror.
Sure Windows Server 2003 can do RAID. Natively, the unit can do RAID 1 and RAID 5 through the software...but the drives will not be hot swappable. If you build a Windows Server 2003 with a higher end RAID card, in other words RAID 1 or 5 through hardware, the card itself will cost more than this Home Server costs. Then you will get the ability to hot swap the drives provided that you have a server class chassis.
This is a great product and I would recommend this buy to anyone who is looking at this product.The customer service is awesome as well
At a very minimum, you need to make sure DDNS is disabled. Had M$ put this in the instructions in the first place, I would have saved a day of screwing around with installation problems. Once this was resolved, the box works great. The PC backup is the best feature, followed by the web sharing of your content. The configuration of this is very intuitive for anyone that has been around computers at all.
It's a minor nit and I know why Microsoft did it that way, but it's still a pain.Aside from these two minor, minor items, I LOVE this NAS!!! !
Accept no substitutes! Buy this product.it is expandable. It is simple to use and setup. I don't know why any home would ever want to be without one.
One thing you don't want to do is make all your personal data available to anyone on the internet! So I will go a little slow in that department. Once I get my other Seagate drives on Monday I hope to add to this post. If for some reason I gave too many stars to this review I will make it known in that supplement that my opinion has changed. However I doubt that that will happen!
He created a case number and told me they will call back, but I doubt this will happen.My guess is HP has bitten off  more than they can chew in trying to support this OS. I would advise anyone looking  at this to buy a generic box and buy Windows Home Server directly from Microsoft where there might be some hope of support. (If you buy this product you are forced to use HP support
Answer: What you want to do is not supported, but there might be a solution out there if you understand how the drive extender technology works.  There is a technical paper about the data structure on the Microsoft website.  http://download.microsoft.com/download/2/f/c/2fc09c20-587f-4f16-aa33-c6c4c75fb3dd/Windows_Home_Server_Drive_Extender.pdf"Windows Home Server Drive Extender does nothing unique to the secondary data partitions or the files on them, which makes enables you to recover most of the lost data-even in worst-case scenarios. If the home server fails completely, all the surviving drives can be attached to a computer that is not even running Windows Home Server Drive Extender, and you can copy the files from the drives to that computer. Because the files retain their original names and paths (under the \DE directory), the files can be used with no specific recovery steps.Important Although this works as a disaster recovery method, moving a secondary hard drive between computers is not a recommended or supported use of Windows Home Server Drive Extender."Also, I found this on one of the webcasts:Q:If you are using "Folder Copy" and a drive fails - can you remove the working drive and plug it into a normal computer and read the files without any special software? A:The data from the File Shares is recorded onto the hard drives in standard formats, so you can pull data off the drives. That said, you really don't know which data is on which hard drive if you have more than one working drive. Q:i have about 500GB - 1TB of data that i will want to archive each year. i.e remove hard drives. But data will not be stored on any one drive. How would i achieve that? Manually copy files to externals? A:there is an add-in created that allows for a USB HDD to be added and accessed without adding it to the storage volume. That way you can easily move the data to that external USB HDD
