Data Recovery Complications
In this article, I will talk about several difficulties ranging from basic to complicated ones that might make the data recovery impossible. I will also talk about the reasons of these complications.
We use data on hard drives and computer systems and are always worried about it’s security. For the protection of our data, we mostly use passwords. There are various levels of securities when it comes to passwords. There are professional systems that use complex programs encrypting information. This kind of security is considered the highest one. The way normal user passwords were being used with traditional operating systems has changed over time. In older operating systems whether it was windows PC computers or Mac computers, the contents could be read offline even if there was a password on user account. Apple started high end security allowing users to protect their information when it comes to accessing it off-line.
Talking of modern operating systems, I have to give credit to Apple who brought secure system known as File Vault. This is a built-in feature in their modern operating systems on all MacBook Pro, iMac, MacBook Air and all other Apple computers. Under this system, if it is turned on, the computer uses the user’s login password and encrypts the data. This is very good feature available in all new operating systems in all Macintosh computers, ipads and iPhones. Windows systems come with their own BitLocker feature that encrypts the data if the feature is turned on. Encryption is very high level system which is not easy to break without proper technology. Encrypted data or passwords are one level of difficulty in data retrieval. There is a second one which will be discussed in the following lines.
When a hard drive, usb, server drive or nas fails, we have to deal with the first line of security which is the password but what if the hard drive fails physically? This is the hard one. When a drive i.e. a traditional storage or flash drive physically fails, this can be a big problem. Password information is stored randomly all over the available space. If an area where the password or key information is stored is not accessible, it will be impossible to recover data even if we have the right password or encryption key. This means, if someone has encrypted password on storage and they format the drive, this will make data recovery impossible. On the other hand data recovery using the right tools and technology may be quite possible if the physically broken drive is properly recovered and then password is applied. A lot of time users try different software and follow online instructions to attempt a recovery. This approach brings the same destruction as if someone deletes or formats a drive that has a secure or encrypted data combined with a password.
There are a lot of online services and companies that claim that their data recovery software can recover any kind of situation. This is mostly not true. Trying different software, copying more content to the drive, running a physically damaged drive unnecessarily increases the high risk losing data permanently. It does not matter if the data is password protected with password or not trying different ways and letting other inexperienced technicians playing with these situations is not recommended ways for data recovery. When it comes to crucial data recovery, it is highly recommended to do a little research about data recovery otherwise risk of losing data will always remain high.
In this article, I talked about some important facts when it comes to data recovery from storage devices that are password protected and they have physically failed.
