data back-up with raid by a professional

The RAID controller will translate and communicate directly with the hard disk drives. Some controller cards have additional utilities to work with the disk drives specifically, such as a surface scan function and a drive format utility. In the case of SCSI based cards, these controllers will provide additional options to manage the drives.

Read/write head is a critical component of hard drive that is used to read data from and write data to the disk platters. When the disk platters start to rotate, head senses the magnetization of the magnetic material. The head can also modify the magnetization. The head operate at a minor height from hard drive platter surface. Head crash generally occurs due to several reasons.


Most data recovery consultants offer a free evaluation of your data loss – depending on the type of data recovery required, Kroll Ontrack can actually help perform data recoveries remotely. Finally, never attempt a DIY data retrieval – you often have only one chance to recover the data. Attempting to recover the data yourself can increase the complexity of recovering the data and even destroy or corrupt the data beyond repair.
We are often asked for the time frame of a recovery. It really depends on 3 variables: 1) What type of failure has occured. 2) What's the extent of the damage 3) Will we have to special order components.

In logical failures, the recovery time is generally about 2 business days. If there is extensive corruption within the file system, or the drive is on the verge of a physical failure, then it may add a day to the process.

In physical failures the average recovery time is anywhere from 5 to 10 business days. In rare circumstances it does take longer to recover the data, especially if there is extensive damage to the platters and/or we have to order hard to find components.
