Data Recovery  

We will all experience data loss sooner or later, if we have not experienced it already. In the computer industry, Hard drives that are used for data storage are becoming more and more sensitive and susceptible to malfunctions and damage. It is not necessarily the manufacturers’ fault; the technological production of hard drives is improving every year. In many cases we, the users, are the main reason for damage to our hard drive and loss of our data. Hard drives simply cannot stand the continuous loading and transferring of such large quantities of files as we would like them to do.

When we experience data loss it is important to remember to stay calm. Many people first think about the worst possibility – that their data is lost forever. Consequently the first reaction is panic. However in most cases, data is not lost forever simply because lost files can almost always be recovered. It is only the process that can be a little bit more complicated and take more time. The worst thing to do in such a case is to try to recover data yourself. If you try to restore your files yourself, it can quickly go wrong and you can make a data loss situation all the worse. Furthermore an even worse action to perform would be to try to fix the internal hardware itself. These kind of interventions, whether they are learned over the internet or suggested by others, unwittingly can and often do result in futher data loss and permanent damage.

So what should you do in case of data loss? As we have suggested, it is important to react calmly. You should immediately stop using the damaged hard drive because any further use can result in additional damages and more lost data. Your next step is to pass your damaged hard drive to an expert. It is really important that the restoration is done by a professional data restorer, because inexperienced persons can lead you towards more harm than good.

Data restoration by an expert will probably take a couple of days. The time depends on the state of your damaged drive. For example it is reasonable to believe a drive that has been damaged by juice or the rain would take more time than a drive that has incorrectly marked sectors as bad. The amount time also depends on whether you created a backup before or not. Backups can speed up data restoration process and save an expert a lot of work as well as lower the final price of the data restoration service.

Just like many things in life, we start to appreciate our files only when we lose them and discover that they are not eternal. Fortunately, there are professionals and experienced data restorers here at Kotar which can take care of your lost data and restore it to its original form.


HARD DRIVE Data Recovery
Over the years, the storage capacity and reliability of hard disk drives has increased dramatically to meet the demands of modern operating systems. Unfortunately, hard disks fail just the same as any other electro-mechanical device and, of course, accidents happen. 
With our hard disk recovery services, we recover data from all brands, almost all hard disk failures and get you back to up-and-running as quickly as possible.
It's important to stop using a faulty or damaged hard disk immediately to prevent further damage. Too many IT experts, computer shops & inexperienced Data Recovery companies attempt to recover data from damaged hard disks using dangerous & risky methods without understanding how hard drives work and why they fail. This is making the problem worse and resulting in more expensive. Be smart. Don't risk ! Turn your hard drive off and call a Data Recovery Specialist. 
Common Hard drive problems which we can solve:
Damaged Heads - Clicking/Knocking sound
Seized Spindle Motor - Buzzing sound
Damaged Printed Circuit Board - No power
Bad Sectors - Read Errors 
Firmware Corruption - common with Seagate 7200.11 drives
File System Corruption
Unable to access any data
Hard disk not detected
Deleted files/Reformatted hard disk
SSD Data Recovery

If your SSD has stopped working and you cannot access the data, the best thing to do is to turn it off to prevent further damage. SSD drives may fail due to many reasons: Firmware Corruption, Faulty Controller Chip, PCB Damage, Detected as wrong size, Bad Sectors/CRC/Unreadable Sectors, Operating System Not booting, Power Surge, Liquid Spill/Flood Damage, Damaged SATA or ZIF Connector, Accidental Reformatting/Deletion of data, File System Corruption, Not Detected in BIOS.

SERVER Data Recovery
If your server has gone down due to a hard disk drive or RAID array failure, productivity can come to a complete halt and severely impact the productivity and business continuity.
Some of the most common problems with RAID and NAS include situations where 2 hard drives fail in a RAID 5 array, or 1 hard drive fails in a RAID-0 array, or a Network Attached Storage External hard drive's RAID controller/enclosure has failed. Most problems are caused by hard disk wear & tear, firmware corruption, shock/impact to the hard drives, or overheating. Most servers or RAID systems are turned on 24 hours a day and are never shut down. Frequently, RAID-5 systems suddenly report 2 drives as 'dead' since 1 drive normally dies at an earlier time without being noticed. This way, the system keeps working on a problem which is't discovered until the 2nd drive actually fails rendering the system Offline. Don't worry - in most of these cases, we can still recover your data.
The time needed to recover data from a RAID array can vary depending on the brand & model of the RAID Controller, RAID configuration, file system type, the problem with the hard drives, ability to locate spare parts if needed and the condition of the data in RAID Array when we receive the drives.
Some RAID arrays can be rebuilt in 1 day, others take several days, or in some difficult cases, weeks! We really need to test the drives, examine the data on the drives, and only then can we determine the cost and time-frame required for the recovery.
Recovering data from a RAID array requires many years of experience in this specific area of Data Recovery field. 
If you notice a RAID Problem:
Do not attempt to repair or rebuild your RAID array. If done incorrectly or with the wrong stripe block size or drive order, this may corrupt your data permanently. Don't risk it!
Shut Down your RAID System, leave all of the hard drives powered off. The sooner you do this, the higher are the chances your data can be recovered quickly and at less cost to you.
Carefully Remove each disk from your RAID array and note the number the Disk Bay number they are removed from or label them with the SCSI ID or Disk ID if this is known. Otherwise number them in the order you remove it (e.g. top to bottom, Disk 0, Disk1, Disk2, Disk 3, Disk 4).
Contact Data Recovey Specialist. 
Put each disk into an anti-static bag and wrap in bubble wrap to ensure the best protection during transport. We do not need your server, RAID controller or any cables, only hard drives. 
USB Flash Drive Data Recovery
USB Flash drives are used as cheap, fast and portable data storage devices by students, families, businessmen, etc. daily. They are a great invention but due to poor design and low quality components used, there is a high failure rate.
We perform Data Recovery from a faulty or damaged USB Flash drive with a hardware problem. We can recover data from most brands and models of USB Flash Drives with a high success rate.
We can also recover deleted files, files from deleted Flash drives and Flash drives which are not faulty but seem to be inaccessible or corrupted due to file system problems.
MEMORY CARD Data Recovery

We can recover photos and files from SD, XD, Sony Memory Stick, Compact Flash memory cards and all other types of memory cards.
Memory cards like SD, XD and CF cards are used mainly in digital cameras today to store photos and videos but can also be used to store files using notebooks, PDAs, mobile phones and other portable devices.
If you have any kind of problem with a memory card, stop using it. Do not take any more photos or format the card. Contact Data Recovery Specialist ASAP to maximize your chances of getting your photos back.

MOBILE PHONE Data Recovery
We are equipped to recover data from mobile phone handsets (internal memory) as well as SIM cards using logical and physical extraction methods.
For most brands of mobile phones, we can recover existing, hidden or deleted text messages, call history, photos, videos, contacts, phone internal data - previous SIM cards used, other phone data: websites, search history.., 
It is not always possible to recover lost or deleted data from a mobile phone, SIM card or memory card. If the device does not keep the deleted data on the device, has erased the data in a secure way or if the data has been overwritten, we will not be able to recover the deleted data. In case you need a mobile phone data recovery service, turn your phone off to prevent overwriting any data. Leave your SIM card & memory card (if installed) in the phone. Find your power charger cable for the phone.  
Pack your phone (with the SIM card) & power charger cable in a box, wrap them in bubble wrap/foam to protect it from damage during transit and bring or send it to our lab.
FORENSIC Data Recovery
If you need a computer forensic examination to be performed on any computer hard disk drive, computer system or external data storage device, we can help you. 
This type of service is normally required if you need computer data files to be presented in court as evidence.
Examples of where a computer forensic examination may be helpful:
- An employee is fired from a company and has deleted all data from his work computer. We can look to recover all possible deleted data and emails. You may find this useful in finding out what the employee was up to in the period before the employment was terminated.
- A person suspects their partner is having an affair or doing something dishonest using your computer. This is common during a divorce or child custody case.
- You suspect somebody has hacked into your computer or put a virus on your computer.

TAPE Data Recovery
When you need it most, it doesn't work. Backups are an important part of business IT operations, however sometimes it's found that the backup has failed, or the tape is no longer allowing access to the data stored on it.
We can recover data from all common tape drive formats from all major backup software formats. We can recover data stored on tape when the backup software no longer recognizes the tape or backup set stored on it. We can recover data from damaged, 'sticky' or broken tapes, from tapes where some of the data has been overwritten, chewed up tapes and tapes with de-oxidized corruption.

It happened. Our only server dropped dead. A server for which we took so good care of let us down. Two out of four discs has stopped breathing and our business path has stopped. Three years of web application development has been destroyed. Read more ... A server did still »act strangely« for a while but after each reboot everything was OK. This was happening for a few months, 2 or 3 times a week, but we attributed this to the fact that the automatic updates were set to self-impose or consequently the computer restart itself.
