is this in Windows or hardware raid?

Check the setup option for the raid controller. On some you can create a raid 0 array using one disk. If yours doesn't have that option, check for other options in the BIOS setup, where you can disable the array and just use the controller as a standard system.

Well, if the PC boots fine then all you will need to do is disable the RAID function for that hard drive controller. &nbsp;Then it will just run as a regular disk.

It is a hardware RAID, Intel Matrix Storage Manager. I can access the RAID utility with Ctrl-I. I removed the uneeded drive in the configuration.

The problem is that if I &quot;un-raid&quot; the drive, there is a message saying that all data will be lost. I don't want to do that.

You could also, just as an extra safety measure, make an image of your system before you do anything. A good utility for that is bootit-ng.<br />

Thanks Rindi - sure enough, the message could be ignored. It worked fine. Thanks

We purchased a brand new DELL Optiplex 755 that came set up with two 250GB drives in a RAID1. We want to remove one drive and have the PC run off of the other, with all the pre-installed OS etc. I have removed one drive from the RAID. How can I get the PC to stop looking for RAID and showing the &quot;Degraded RAID&quot; screen on boot-up? I also don't want to lose the OS, etc. on the drive. Is this possible?<br />
Thanks

Can I remove a RAID1 drive and have the PC run off of the other, in a non-RAID, without reformatting?

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.
