Data Recovery from RAID and NAS Systems
Data Recovery from RAID System
RAID recovery services from the most experienced data recovery company.
- RAID is lost from my system!
- A drive from RAID SCSI on our Server is broken!
- There is an indication that the SCSI drive in the RAID needs replacement!
- There is a RAID error and I don’t know what to do!
- I need immediate data recovery from RAID in Greece!
RAID systems are common mainly to corporate customers and most R.A.I.D. systems consist of SCSI or SAS (Serial Attached SCSI) hard drives. Data recovery from SCSI and SAS drives, is a particularly difficult procedure on itself due to the construction of these drives, all the more so when they are located in a RAID array.
TicTac Data Recovery specialises in SCSI Recovery and SAS Recovery
SCSI and SAS disks are hard disks specially made for servers. They are faster and more reliable. TicTac is the most experience Data Recovery company in this field. We have invested in purchasing diagnostic equipment that supports most SCSI and SAS models, so we can tell in 2-3 days, what exactly is the problem with your SCSI/SAS Hard disk. We receive more than 3 SCSI/SAS cases per month and most of the problems are resolved within 5-15 days. If your SCSI hard disk or your SAS hard disk failed, then TicTac is the greek data recovery company that you should trust to have the best results for your data. Most SCSI or SAS disks come into RAID arrays and most of the time they consist of 2 or more drives.
What do you need to do when your RAID system is broken?
Should a RAID system collapse the actions that need to take place would need to be taken by one who has good knowledge of the RAID technology before one attempts to tamper with a Server or NAS that has a problem and has a RAID array. Otherwise, one wrong move can destroy all data on your system. RAID arrays, that are commonly found in storage systems and backup Servers, are particularly vulnerable to human error due to their complex operation.
Caution is required by the technician who will work with the system before coming to our labs:
- If you replace the drive, the new drive should be new and clean. The use of a drive that was in another RAID system is prohibited.
- Label with an indelible marker wires leading to each drive as well as the drives. It is very important, when you contact a RAID system data recovery company, that they know which drive was connected to each cable. The best thing to do if you notice a problem in the RAID array is to transfer the entire unit to the laboratory where the data will be recovered.
- The RAID Controller as well as the cables need to be transfered to to our laboratory and it would be best if they are not disconnected from the drives.
- If one or more of the SCSI or SAS drives of the system, makes no noise or all you can hear is a “tak tak” you need to accelerate the transfer of the system to our laboratories, since it usually means that the drives are in an unstable condition.
- The conventional recovery tools do not work on drives which are located in a RAID array and their use is not suggested since they can cause irreparable damage.
Contact immediately a specialized company to recover data from your RAID system and don’t do any tests since RAID systems are particularly sensitive to technicians’ errors.
RAID systems are implemented for the following reasons:
- Data security, so as a RAID system can write simultaneously to two or more drives.
- Speed, where the implementation of record is done on two drives simultaneously and nearly the double speed is achieved.
- Speed and security.
Tic Tac Laboratories offers specialization on RAID Servers and SCSI RAID Servers
SCSI drives and RAID systems, due to their great cost, are used mainly by corporations that require a more reliable solution for their backup Server, to ensure maximum security for stored data. Therefore, lesions concerning ATA RAID, SATA RAID, SCSI RAID and now SAS RAID are not so common.
Up until 2010 such cases (SCSI & SAS) were dealt by our parent company abroad. Since 2010, however, the administration of TIc Tac Laboratories, after accepting several such incidents, decided to invest in specialized equipment for recovery of SCSI RAID and SAS RAID in the laboratory.
Types of existing RAID systems
|TYPE||DESCRIPTION||MINIMUM DRIVES #||ERROR TOLERANCE||IMAGE|
|RAID 0||Used to achieve higher speed. Both drives need to get recovered to have full restoration.||2||0 (none)|
|RAID 1||The image of the filesystem of the first drive is generated on the second.||2||n−1 drives|
|RAID 2||Bit – level striping||3||RAID 2 can be recovered automatically by the failure of a drive or part of the files.|
|RAID 3||Byte – level striping||3||1 drive|
|RAID 4||Block – level striping||3||1 drive|
|RAID 5||Block-level structure||3||1 drive|
|RAID 6||Block-level structure||4||2 drives|
I’ve lost my files. What should I do?
What clients who got their data back say about us:
Very professional team. Thanks for the help provided. 10000% recommended. Personalized attention, they even speak Spanish!!! Everything is very easy with them. Thanks to Katerina for always keeping me updated.
Great experience on a really hard case, 100% recovery success from raid0 SSDs. Friendly and professional.Highly recommended
Tic Tac Data Recovery provided a very good and professional service. The damaged hard drive was given to two specialists data recovery companies in the UK who could not recover any data. (Note: these two UK companies carry out both forensic and security work)
Well done Tic Tac for a good job!
