Physical Functions of Drives, Labs 3. Logical Corrupted Data Recovery 4. Theory, System Area, Fundamentals 5. Data recovery is necessary when source material fails and where no good backup exists, either Physical or Logical. What this means is that time is not on your side.
If there was a backup that had been done 24 hours ago, you should consider restoring that backup. Doing a data recovery is going to require quite a bit of time, so you dont want to delay getting the asset back up and running.
However, you do want to protect the content that is on that drive or array and keep it from getting overwritten. In addition, what you will get back may not always be in as pristine shape as the backup, pc 3000 udma download bittorrent.
So you should always advise a client to do what needs to be done pc 3000 udma download bittorrent get back in business and address recovery secondary. There may still be valuable files that need to be recovered that were changed or written within that 24 hours; however, it may take you a week to get these files, especially if the server or drive is substantial in size, or depending on the condition of the media.
If there is no backup, the data you have will be very valuable. However it does have a lifespan. For example, doing a recovery pc 3000 udma download bittorrent take several weeks, and during that time frame, the client might have to start re-creating their content. If they get done before you do, it is likely they will no longer need what you have. In the business model the data recovery companies run under, in most cases this means the client does not need the data and generally the client will not pay you for your work if they no longer need the data.
Forensic data recovery is generally completely different. Your data will generally be valuable whenever you complete the job. There are still some time considerations, but in most cases it can take several months, and there will still be some value. Wikipedia: Forensics is the application of sciences for the use of or to answer questions for a legal system.

Image Goals and Automation Changes to the hard drives Forensics vs.
This class is meant to be a complement to the classes you have already taken, and we do not delve into walking though the files system structure itself. We will cover the items that are unusual or that make the data recovery world different. There are times when you are making modifications to the drive in order to copy the data.
HPA, etc. Bad sectors, pad with zeros. A clone is a copy of the drive. In data recovery its backwards. Our goal in Data Recovery is automation. In Data Recovery they just want their pictures back. If you get 25 drives a week for Data Recovery, its all about automation. Physical: i. This is the type of data recovery when there is damage to the media and the pre-existing data needs to be retrieved This will usually require the media to be repaired, pc 3000 udma download bittorrent.
In most cases this is where the majority of the work is It will generally require one or more donor drives or other hardware to repair it back to working condition There are two types of data recovery. The first type is related to drive failure and is physical, such as the controller failure or some kind of corruption. It generally means that you will be fixing some sort of media or performing some manual work in order to repair the content. In many cases youre going to have to acquire whats called a donor drive.
Its very similar to an organ transplant, and not unlike an operation. The donor drive in many cases has to almost exactly match the original drive. There are a number of tools involved, and you will be dealing with very small parts and exchanging them. Not every drive can be rebuilt and it is a difficult task, however it is possible.
You will be taking apart and rebuilding several drives this quarter. This class is about process, and teaching you what you can do, with practice, after you leave this class. There are a couple items that might also fit into this category, one being passwords on hard drives. When a hard drive is password-protected, using the computers bios to enter the password, and someone takes the drive and plugs it into a USB connector, the drive will exhibit an error that looks like an abort error.
It will not allow you to copy even one sector of data. The client doesnt know this, and in many cases they will not even remember there was a password on the drive.
Logical: i. Deletion, Purposeful or Accidental The second type of data recovery is when files were purposely or accidently deleted, or locked by passwords. With this type of data recovery there is usually no damage to the media and standard software can be used to recover the data.
This is the process that most data recovery software performs Because most software relies on calls and functions from the operating system for input, and it has no control over error correction or any hard drive functions that the operating systemvery few software programs understand damaged media The second type of data recovery is Logical.
Whether deletion is on purpose or accidental, it is still considered data recovery. From time to time, you might get someone who was writing a book and accidentally saved over it, not realizing what they had done. You will be called on to recover the content. This might be a type of partition corruption or maybe catalog corruption, but whatever the reason the person just wants their data back. Now, pc 3000 udma download bittorrent, this is where things get more complicated.
Lets assume that you have the drive in for recovery, and you hook it up and see that the drive is password protected. In many cases you might think thats what the recovery actually is, getting the data back bypassing the password, pc 3000 udma download bittorrent.
So you bypass the password, see the files, copy them, and give it back to the client. Next thing you know, they call and complain that the files that they are looking for are not there. Then you find out the files were deleted, and they did not even remember they had a password on the drive.
You wont hear the story until after you have already done the job. So I would say if you see a situation like this, pc 3000 udma download bittorrent, you have two choices. Clear the password and the data recovery of deleted files, or call the client and ask them the situation.
Diagnostics of the drive is the first step. If the drive can be imaged go to step 3, otherwise continue with step 2 2. Repair the hard drive so it is running in some form, usually requiring hardware or special equipment 3. Image, Copy, or Recover the physical drive and sectors primarily by bit stream imaging. If the drive is functioning, it is possible to do this with software; however, there are some hardware solutions that work very well with damaged drives 4.
Perform Logical Recovery of files, partition structures, or necessary items; usually this is by software and is the most common type of application sold 5. Repair files that might be corrupt or have existed in damaged space or sectors to recover what is possible. This is usually the requirement in Forensics, to be able to re-assemble data to display what was there, whether full or partial data is present Depending on the type of data recovery, you will have five phases.
You can diagnose the problem many ways, but one of the easiest is to attempt to image the drive using hardware or software. There are some pieces of software that can talk to the drive and help you diagnose the type of problem before continuing. Until you have done this you generally will not see any data and that prevents you from doing the other steps.
In essence, pc 3000 udma download bittorrent, if you cannot repair the hard drive, that is the end of your job. The third phase of data recovery is imaging. Not all data recovery companies image their drives.
I generally find it to be very valuable to image the drive and work from the working copy. This allows me to maintain the state of the original drive without making changes to it, because as most of you know, making changes to the original drive is a bad thing.
Lets say I have a bad drive that came from a Mac, and I hook it up to the Macintosh, pc 3000 udma download bittorrent, and run a tool like disk warrior against it. Now, if disk warrior tries to make changes to catalog, you will have no resource to go back to, and in many cases you will not know what type of damage you have to the drive until it is too late. In some cases, if the drive is damaged you might just get the one shot, so you have to be very cautious not to waste your one shot.
Pc 3000 udma download bittorrent believe that you should make a physical image or clone of the drive before you proceed to the third step, logical recovery. There are several tools specifically for dealing with damaged media. There is also some excellent hardware for doing imaging from physically damaged hard drives ,such as the DeepSpar Disk Imager.
And then the third step is the logical recovery pc 3000 udma download bittorrent where youre repairing partition structures or corruption and software. This is what the most common types of data recovery software do.
They work by talking to the operating pc 3000 udma download bittorrent ,making requests and expecting a response. In pc 3000 udma download bittorrent cases, they have pc 3000 udma download bittorrent idea how to talk to damaged media or corrupted files and can cause them to fail.
Most of the software in this category is defined by how good the headers are in the application. Most of them began by scanning the hard drive from beginning to end, examining header information and trying to determine what applications or data files are on the drive.
Some can parse the MFT or fat table or whatever catalog the operating system of the damaged drive is, but others only scans for file headers or partitions structures. We will cover some of the most common applications and what your options are for repairing some of this corruption. Most of this focus will be on automation primarily, because in a data recovery lab youre handling dozens of drives a week and just would not have the time to do everyone by hand.
