Dell Server Hard Drive Failure, HDD Replacement and RAID Recovery

Dell RAID Server HDD Failure and Status Codes

Dell servers are reliable, but hard drive failure can still happen without warning. When your system shows RAID errors, HDD status alerts or offline drives, fast action is essential to prevent data loss.

Data Clinic provides specialist Dell RAID support, HDD replacement and data recovery services for businesses across the UK.

This page explains the most common Dell RAID status codes and when to contact Data Clinic for safe diagnostics and recovery.

RAID HDD Status Codes on Dell Servers

Administrators often see one or more of these drive states in the Dell PERC controller or OpenManage:

  • Unknown – The drive was previously part of another RAID set or controller.
  • Ready – Drive is operational and available for assignment.
  • Failed – The hard drive is not functioning and must be replaced immediately.
  • Online – Drive is healthy and part of the active RAID set.
  • Degraded – The RAID array has a failed drive and needs urgent attention.
  • Recovering – The system is attempting to fix bad blocks.
  • Resynching / Rebuilding – Common after a drive replacement or RAID reconfiguration.
  • Removed – Drive is no longer part of the RAID.
  • Diagnostics / Formatting / Initialising – System-level processes running on the drive.

If your Dell RAID displays anything other than ONLINE, Data Clinic can assess the fault and advise the safest next step.

Common Signs of Dell Server Hard Disk Drive Failure

Businesses usually notice one or more of these issues before a RAID failure:

  • RAID volume showing degraded or offline
  • PERC controller alerts
  • Slow performance or timeouts
  • Clicking or grinding noises
  • Multiple drives reporting predictive failure
  • Inability to rebuild the array
  • Sudden boot failures

If you’re seeing these symptoms, stop using the system and contact the Data Clinic before attempting a rebuild.
