FAILURE DIAGNOSIS

The most common “data recovery” scenario

The most common “data recovery” scenario involves an operating system (OS) failure (typically on a single-disk, single-partition, single-OS system), in which case the goal is simply to copy all wanted files to another disk. This can be easily accomplished with a Live CD, most of which provide a means to mount the system drive and backup disks or removable media, and to move the files from the system disk to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.

Another scenario involves a disk-level failure, such as a compromised file system or disk partition, or a hard disk failure. In any of these cases, the data cannot be easily read. Depending on the situation, solutions involve repairing the file system, partition table or master boot record, or hard disk recovery techniques ranging from software-based recovery of corrupted data to hardware replacement on a physically damaged disk. If hard disk recovery is necessary, the disk itself has typically failed permanently, and the focus is rather on a one-time recovery, salvaging whatever data can be read.

In a third scenario, files have been “deleted” from a storage medium. Typically, the contents of deleted files are not removed immediately from the drive; instead, references to them in the directory structure are removed, and the space they occupy is made available for later overwriting. In the meantime, the original file contents remain, often in a number of disconnected fragments, and may be recoverable.

The term “data recovery” is also used in the context of forensic applications or espionage, where data which has been encrypted or hidden, rather than damaged, is recovered.

10 EARLY WARNING SYMPTOMS OF HARD DRIVE FAILURE:

VERY NB – IN CASE OF ANY FAILURE IT’S ADVISABLE TO AVOID POWERING THE DRIVE AS THIS COULD CAUSE IRREVERSABLE DAMAGE AND REULT IN NO RECOVERY.

Sign 1 – You hear high-pitched whining, loud clicking or grinding noises coming from the drive
A normally operating drive will make a smooth “whirling” sound as is spins up or down. But if a drive has a grinding or clicking sounds (the Read/Write heads scraping too close to the magnetic platters), then your drive is sick and is on the way out. Read more to analyze the clicking sound on your Hard Drive in other post dedication to the topic..

Sign 2 – You see the infamous “Blue Screen of Death”, repeatedlyimage2
BSODs (Blue Screens of Death) are actually called “Stop” errors and they only appear when your Windows system is experiencing severe software or hardware issues. Often BSODs can cured with a careful “Repair Install” of theWindows operating system or by removal of a bad device driver. But if these software fast fixes don’t seem stick, then your hard drive is usually on its last legs. You can use a nice BSOD investigation utility, as manual identification of the presented problem description is not an easy task.

Sign 3 – Your computer keeps re-booting on its own
The problem s not very frequent, and in some cases it can be attributed to hardware issues. It might be a dust covered motherboard, and an overheating processor. But, in a vast majority of the cases, it might be due to bad drives. The detailed problem investigation is offered in my earlier dedicated post.

Sign 4 – The computer locks up during booting
The occasional hanging during the boot process shouldn’t worry you too much but when it happens like every other startup, these could be red flags for a serious problemt.

Sign 5 – Your system keeps having frequent freezes or hang ups
You are working along just fine, and then suddenly everything comes to a halt. The program freezes up on you. Your mouse and keyboard seem to stop responding. The only solution is to reboot.

Sign 6 – The Missing Files
It happens once awhile, you might delete a file and not know you did it, but if files randomly start turning up missing, start worrying.  The next file to go AWOL may be an integral system file that the entire operating system hinges on.

Sign 7 – Error message: hard drive is not formatted
This a fun message that you will get when you start up your machine. You may be able to restart and get it to boot into Windows a few more times but this error is “fur-sure” sign that you drive is very close to death. And by the way don’t try to format the drive! You will lose all your data.

Sign 8 – Error message: boot drive or device not found or drive cannot be accessed
Unfortunately, this not very funny message happened many times in my troubleshooting career. In most cases I was still able to retrieve the data from the drive, but reviving the drive is rather a complicated task. You can check the CD/DVD trays or the floppy drive to make sure no stray disks are stuck inside. You can also check the BIOS to make sure the system is booting from the hard drive first. If all these tests are no-good, then the drive is a goner.

Sign 9 – Errors: Operating system not found or Missing Operating System
This is a bad one. Even the Microsoft technical support knowledgebase has only got a few causes for this error message. Basically your PC can no longer detect the hard drive or the drive is too severely damaged to read (DOA).

Sign 10 – Accessing, opening, or saving files are taking awfully slow.
It’s like your computer’s memory has suddenly decreased into nothingness such that even small document files are too much for its capacity. Do not panic, check first if your Hard Drive is not full. We always recommend our customer to keep Hard Drive full of no more than 70% of its capacity. It is definitely suggestion on a safe side. But you want to be safe as well?. If you are unsure please bring it to us to assess before it’s too late.
Data recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible storage media when it cannot be accessed normally. Often the data is being salvaged from storage media such as LAPTOPS, internal or external hard disk drives, solid-state drives (SSD), USB flash drive, storage tapes, CDs, DVDs, RAID, and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system.
