Hello,<br />
<br />
Have you tried to see the current configuration of the controller before starting windows? Try to access into the controller menu and check how many logical devices are there.<br />
<br />
You can plug the disks into another raid controller but you must ensure that the other raid controller is the same manufacturer and model as the old one.

Hello,

Hi,<br />
<br />
Adaptec 2420SA controller, Windows storage server 2003, HP Proliant DL100G2.<br />
<br />
We have 4 disks, 3 logical devices using RAID 5. One disk failed, therefore we replaced with a new disk. <br />
<br />
Problem, once replaced the disk the logical device 3 failed and logical device 2 and 1 are now degraded. Looking via Storage Manager the new drive is only part of logical device 1 and 2 and not 3 as it should be. All disks status are optimal. We can boot the system up for the OS is on logical device 1 however all data is on logical device 3<br />
<br />
I know you can use RAID Reconstructor but I cannot see the disks under windows disk management so the RAID reconstructor will not work.<br />
Is there a way to rebuild the logical devices without Data loss ? Can I take the disks out and plug into another RAID controller ?

RAID 5 - Logical device failed

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

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server 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.
