RAID systems were designed specifically to protect against data loss, yet even complex systems can suffer catastrophic failures.

RAID arrays typically tolerate a single drive failure without affecting server availability on the network.

However, if more than one drive fails, stops working, or one or two drives drop out of the array, it can create a catastrophic situation for the company and its partners. We treat data security and confidentiality as top priority for RAID systems as well!

Supported file systems:

• LDM és MDADM, WSS (Windows Storage Spaces), ZFS RAID-Z, BtrFS RAID, Apple Fusion Drive (HFS+, APFS)
• FAT, exFAT, NTFS, ReFS, HFS+, APFS, EXT2/3/4, XFS, F2FS, ReiserFS, BtrFS, VMFS, UFS1/2, ZFS, VMs – virtual machines

Every RAID recovery case we receive is treated with high priority, because we know and understand how critical these systems are for companies—for example, databases or multiple websites hosted on a RAID array.

Which RAID levels do we recover?

• RAID 0
• RAID 1
• RAID 3
• RAID 4
• RAID 5
• RAID 6
• RAID 0+1
• RAID 10
• RAID 50
• RAID 51
• RAID data recovery: Mirror, JBOD, 1E Offset, 1E Adjacent, 4, 5, 5E, 5EE, 6, 6 Adaptec, any combination (10, 50, 51, 60…)

Drive interface types:

• IDE / ATA / PATA / EIDE
• SATA II/2.0
• SATA
• SAS
• iSCSI
• SCSI
• Fibre Channel
• USB
• Firewire
• eSATA

Even the best-configured systems can fail:

• Damaged or lost RAID configuration
• Failed software or OS update
• Corrupted partition table
• Drive won’t boot – missing or deleted file/folder
• Inaccessible volume
• Bad sectors
• Clicking drive
• Faulty RAID controller/control
• Damaged striping
• Incorrectly rebuilt RAID
• Formatted drive
• Multiple drive crashes/failures
• Fire/flood damage
• Accidental media swap
• Accidental reformat of the entire RAID array
• Lost array configuration

If a RAID server failure occurs, don’t panic! Shut down the server and power off the system!

• If you are unsure about the RAID’s condition, do not attempt a reboot—it may damage the array.
• If you hear unusual noises from any drive, power down immediately.
• If not done yet, label the physical slot/position of each drive in the RAID.
• Number the drives starting from 0. Example: for a 5-drive array, label them 0–4.
• Do not run volume repairs or defragmentation on any suspected bad drive.
• Do not replace a drive with one that previously belonged to another RAID system.
• If you are unsure about proper RAID/server operation, avoid any repair attempts.
