CERTIFIED AND SECURE RAID DATA RECOVERY SERVICES.
RTS offers 24 hour RAID 1 data recovery services. RAID 1 (mirroring) – the basic idea of such a solution is the replication (mirroring) of two or more discs. It means that while using RAID 1, an exact copy (or mirror) is created on two or more discs. Such a solution gives good read performance and reliability, but storage capacity must be compartmentalized. The reason for this is that the total storage must be equal to the capacity of the smallest disk. i.e.: in the case of an array composed of 3 discs – 250GM, 500GB and 1TB – the usable space will be equal to 250GB.
RAID 1 is the easy way to secure data and maintain a reasonable value of write, read and access speed. Adopting this strategy allows for full optimization of these processes. While it is sequential, the overall write speed is equal to all the write operations of each drive in the array. It’s a simultaneous process, the write operations take place parallel to all drives – which means that the recording duration is equal to the duration of the operation of the slowest disk. It is also possible to set up this strategy for the read process. It can be sequential – so the read speed can be almost equal to RAID 0 or it can take place only from specified drives. The second solution is used when there are significant differences between the read speeds of each of drive in the array. But returning to the pros – the possibility to increase read speed and reduce access time is the main advantage.The second one is data safety.
Pros: RAID 1 offers excellent read speed and a write-speed that is comparable to that of a single drive. In case a drive fails, data do not have to be rebuild, they just have to be copied to the replacement drive.RAID 1 is a very simple technology.
Cons: The main disadvantage is that the effective storage capacity is only half of the total drive capacity because all data get written twice. Software RAID 1 solutions do not always allow a hot swap of a failed drive. That means the failed drive can only be replaced after powering down the computer it is attached to. For servers that are used simultaneously by many people, this may not be acceptable. Such systems typically use hardware controllers that do support hot swapping. When disaster strikes and you are faced with a data loss situation, we can help restore your mission critical data quickly and efficiently regardless of what caused the loss of data.

Common RAID 1 Failures
Physical RAID Server Failure
Physical failure of your RAID 1 Server components can leave you stranded without access to your important files that you use on a daily basis. This can include the failure of the following components: RAID 1 controller, RAM, power supply, motherboard or backplane. Regardless of the RAID 1 server failure, our experienced RAID engineers can recover your data.
Logical Failure of RAID 1 Server System
Logical failures are when the operating system, IE: Windows, Mac, Linux, Novell, Unix, or VMware system becomes corrupted. This could be caused by a virus attack, improper shutdown due to a power surge or power failure, an update that was performed or user error that caused damage the operating system to the point where it fails to boot, boots in a loop, blue screens, etc. At this point, you have no access to your data and you need to speak with one of our RAID engineers to determine what to do next.
Whether the data on your RAID 1 server was accidentally deleted or the RAID 1 configuration got corrupted or formatted, there’s is a very good chance we can still recover all your files. If a user error occurs, its vitally important for you to stop using it and turn it off. Everything you do after the initial problem greatly reduces the chances of a 100% successful recovery.
Physical Hard Drive Failure of RAID 1 Hard Drives
Physical hard drive failure is when the mechanical parts of one or more of the hard drives in your RAID 1 server fail. Mechanical failure like these usually require clean room work to successfully recover your data. If one of your RAID 1 member drives suffer a mechanical failure, you need professional data recovery services to recover your critical files. Our engineers have the experience, tools and equipment to repair your RAID 1 member hard drive and quickly recover your files in our class 100 clean room.
What to do when your RAID fails.
- Do not run any chkdsk options like FSCK, or CHKDSK. These utilities can corrupt or destroy your file system.
- Do not try to rebuild the RAID array. Doing so can wipe out data needed to recover the data you are seeking.
- Do not remove several failed drives at once hoping to reinitialize the array.
- Do not lose the correct order of the drives in the array.
- Do not try to repair any damaged drives yourself.
Be sure when removing the drives to label them in the correct order when preparing to ship them out. This saves us time when virtually rebuilding the array. Find out what time of RAID array you were using, what kind of server, what filesystem, and operating system. If possible which drives are bad, and which drive failed last.
**Important** We need all original disks that were in the array the last time it was operating normally.
While most all data recovery companies don’t offer a free diagnostic when receiving the RAID because of the many hours involved, we offer our ONE RATE fees for RAID data recovery. A RAID recovery specialist will gather information from you over the phone to give you a general idea of what you can expect. Even though RAID recovery falls under our ONE RATE fees, the cost will fluctuate base on the possibilities. Our ONE RATE fee structure will by far beat any price out there. Please call us before attempting to repair the RAID yourself which could end up destroying it.
What You Can Expect during your RAID Data Recovery Process:
- You will be assigned a personal service representative for your project who will guide you through the process.
- The data recovery process can take 7 to 10 business days based on many factors, see below.
- The assigned service representative will be in daily communication with the data recovery technician working on your case and keep you up-to-date with the recovery progress.
How Long Does RAID Recovery Take?
One of the first questions we get asked by most customers is “How long will the recovery take?”. Unfortunately there is no clear cut answer to that question, as each case is different. Many arrays can be rebuilt in only a day or two. However here are some factors to consider that may affect the overall time frame of the data recovery.
Hardware Condition – A drive that is fully functional is much faster to recover data from than one that is severely damaged and must be repaired. So cases that are simply related to accidental deletion, format, viruses, etc. are generally pretty quick on the turnaround. Usually within 24 to 48 hours for most cases, however there are times when it takes longer. Drives needing hardware recovery generally take about 7 to 10 days, but can take longer based on other factors below.
Drive / RAID Array Size – Even if a drive is fully functional a 4Tb drive will take as much as 20 hours to perform a single scan, and a typical recovery may involve several scans to effectively find all files. Also as a professional data recovery lab, we always clone the drive first to prevent any possibility of accidents while working with the data. As a rule of thumb expect an extra day for drives larger than 500Gb or a few days for drives larger than 2Tb. Plus for very large arrays, there can be substantial time.
Number of Failed Drives – In striped RAID arrays the number of failed drives can affect the turnaround time as well. When there are multiple failures all drives must be analyzed to determine which hard drive(s) went offline first so that the correct data is used during the rebuild.
Availability of Donor Parts – For drives with hardware issues, parts are often needed to repair the drive to a semi-functional condition where the data can be successfully extracted. Some hard drive sub-models are very common and easy to find the parts from one of our vendors. However others are not. At times we may even have to spend weeks searching online and calling other data recovery labs for the specific drive or parts we need. Or we may even have to buy a donor drive from overseas and wait for it to arrive. Usually this is the longest part of the whole process for hardware level recoveries.
Functionality of Drive After Repair – Many makes of hard drives don’t take kindly to replacement parts, and don’t function anywhere near their full potential after an internal repair. As drives write magnetic data on a microscopic level, even the slightest micro variation (or micro jog) in manufacturing of parts may cause the drive to constantly have to re-read data over and over. While rare, some drives can take a month or more to extract all the data after such internal repairs.
Pricing for RAID Data Recovery?
Our RAID data recovery prices are based on the number of drives in your RAID array, drive capacity, type of drives, type of failure, file and system type. Even though RAID recovery falls under our ONE RATE fees, the cost will fluctuate base on the possibilities. Still, our prices are the best in the industry. We will match or beat any reputable data recovery company’s price for RAID data recovery, that’s our lowest price guarantee.
How Do I Get My Data Back After Recovery?
Upon completion of the recovery, you are welcome to provide your own return media. For RAID arrays, they would generally be a high capacity external hard drive. Or, if you’d prefer you can purchase a new external hard drive from us at a competitive price and we’ll copy the data to that. For very large arrays containing large amounts of data, arrangements may be necessary to copy the data onto a NAS or other enclosure with RAID functions. Please contact us for more details if you require recovery from such an array.
