According to the latest annual survey of hard drive reliability by Backblaze, a provider of cloud backup services, the annualized failure rate for modern hard drives is around 2 percent. This means that if we have a group of 50 people, with every person in the group using two hard drives (perhaps one inside a personal computer and one inside a laptop), then one of those 50 individuals is going to lose all the data stored on the hard drives within a year.

As with so many other things in life, preparation is the key to success even when it comes to hard drive repair and recovery. If you know why hard drives fail and are familiar with some of the most popular hard drive repair and recovery solutions, you have much better chances of seeing your files again.
GParted is a free, graphical partition editor that you can use to resize, copy, and move partitions without data loss or file corruption. You may want to shrink a partition to create space for another operating system or a backup partition. GParted is part of many other hard disk tools, such as Clonezilla or Partclone. It can also be downloaded from the official website as a small bootable GNU/Linux distribution for x86 based computers and used from a USB flash drive.
While Windows comes with a built-in hard disk repair tool capable of fixing bad sectors and file access issues caused by them, it pales in comparison with HDD Regenerator. This special-purpose hard drive repair tool has the ability to detect physical bad sectors on a hard disk drive surface and repair them a recovery technology called Hysteresis loops generator. Originally developed by Dmitriy Primochenko, Hysteresis can make unreadable data readable again, and HDD Regenerator makes it easy to apply it on Windows XP/Vista/7/8/10.
FAQ Can hard drives be repaired? Yes, hard drives are repairable. But keep in mind that it is not recommended to try to fix a hard dry by yourself since it is very easy to make things worse. If you want to repair a hard drive, the best option for you is to resort to a professional service.
When checked on another computer, and with no need for spending money on data extraction expertise or software, the very likely case is that your external USB or thunderbolt HD is in fact fine, and merely the card interface, or SATA bridge card has failed or is failing. Keeping a HD dock around handy, or cheaper still a $20 hard drive enclosure or a SATA to USB connector can be a real life saver in getting your drive back to use, when the drive itself is fine, and merely its interface card has gone bad.
The rare exception (but growing more common) is a 7mm thick "slim" external USB HD in both Toshiba and WD in certain models where the SATA bridge has been incorporated into the HD controller board, to save time of mfg. and money in production costs. Current production (late 2013 and on) Toshiba 2.5" "Canvio" and most USB WD drives have incorporated the SATA card into the HD controller boards which eliminate a quick and easy fix on this issue. Larger "desktop" external hard drives (i.e. 3.5" boxed drives) do not encounter this issue currently from any mfg.
Countless 1000s of good external hard drives are thrown away each year because the owner thought the HD was bad when it fact it was the SATA bridge card which had failed. This card is removed in a matter of mere second once an external USB HD is cracked open from its plastic casing to reveal the bare HD and the attached SATA card which attaches between the HD and the USB cable.
A couple distinguishing factors are that when the SATA cards inside the external HD are hooked to another computer they may appear as normal, this typical power variance which is odd is typical of SATA bridge failure. Since these bridges not only transfer power but also of course the data, their failure or failing state can show under multiple symptoms making perfect diagnosis often not possible until the SATA card is removed and eliminated as the likely cause of the failure to read and write to the drive.
The best method for your data archives and redundancies, which is also the least expensive, the most reliable, and the most compact option is the purchase of naked hard drives and at least one USB 3.0 HD dock ($40 roughly).
While regarding Time Machine and your Macbook or desktop, your primary backup is best saved to a conventional USB (or Firewire / thunderbolt) hard drive inside an enclosure, the most important part of your data protection begins after your 1st / primary Time Machine / backup; and these are your secondary (most important) data storage devices, archives and their redundancies.
Whether you have a desktop or laptop computer, using an external adapter is the easiest way to connect an old drive to your new Windows 10 computer. The most common type converts the drive connection to a USB connection, providing both data and power in one convenient package.
There are two types of external USB drive connector. One is a total enclosure, converting an internal drive to an external drive for long-term use. The other type of connector strips away the enclosure entirely, leaving only a cable and connector. This is perfect if you have multiple drives to check or only want to temporarily access a drive to transfer data.
If your hard drive contains vitally important information, you might want to invest some money in professional data recovery. Alternatively, How To Extract Files From a Dead Hard Drive has some ideas of how to get data from a dead hard drive.
How important these factors are to you depends on how the SSD is used. The right question to ask is how a drive will perform in your application. There are different performance and reliability criteria depending on whether the SSD will be used in a home desktop computer, a data center, or an exploration vehicle on Mars.
Manufacturers sometimes specify the type of application workload for which an SSD is designed, such as write-intensive, read-intensive or mixed-use. Some vendors allow the customer to select the optimal level of endurance and capacity for a particular SSD. For instance, an enterprise user with a high-transaction database might opt for a higher number of drive writes at the expense of capacity. Or a user operating a database that does infrequent writes might choose a lower drive writes number and a higher capacity.
There are two ways in which a bad block can affect your files, 1) the system detects the bad block while writing data to the drive, and thus refuses to write data, and 2), the system detects the bad block after the data has been written, and thus refuses to read that data.
4) Crashing During BootA crash during the computer boot is a sign that your drive could be developing a problem. You should make sure you have a current backup of all your data before it gets worse and the drive fails completely.
The PC-3000 UDMA coupled with the Data Extractor UDMA forms the PC-3000 UDMA Professional System that allows you to recover data from SATA, ATA (IDE) HDD. If you wish to repair these HDD, you need only the PC-3000 UDMA, and for data recovery you need the combination of PC-3000 UDMA and Data Extractor UDMA.
When developing the new PCI-Express-based PC-3000 UDMA system, we used the main features from the previous generation of PCI-based PC-3000 UDMA, which proved to be the best, most reliable, and most optimally performing data recovery system possible, while at the same time maintaining a reasonable price.
Two ports are separable, but when they are both in use they are dependent. There is a slight reduction in performance on the second channel when the first one is fully loaded (no more than 20% reduction) as the PC-3000 UDMA is based on a single-channel PCI-Express bus. At the same time, this technical solution allows a reduction of the total cost of the board and makes it more attractive for small and mid-sized data recovery companies.
To make initial diagnostics, the PC-3000 universal utility is launched. It diagnoses the HDD in user mode. The following checks are done: if the HDD is identified and if the HDD is password locked; check of surface access by LBA to the user data area and HDD translation system etc. If there are any HDD malfunctions, a special vendor-specific technological utility (intended for a specific HDD vendor) is used to repair the drive and gain access to user data in technological mode.
The PC-3000 UDMA includes 16 special utilities used for various vendors, architectures and HDD families. Special utilities help to conduct HDD diagnosis on a low level, reveal damages and try to exclude them using special program methods and gain access to user data. If you wish to only repair the HDD and you do not need user data, you can make full drive initialization, switch off damaged heads, hide defects on the magnetic surface and reconfigure the HDD.
The PC-3000 UDMA Professional system has a massive database of factory firmware resources: FLASH ROMs, service area modules, service area tracks and other HDD critical resources. The database is systematized and stores all data in compressed format. It allows getting quick and easy data access and sharing firmware resources between several PC-3000 Kits.
The new update has brought the enhanced T2 Reading and Analysis Mode, the support of PS5012, PS3112, and of new SAS SSDs, as well as many more other useful features to improve your work with data recovery cases! All this is available in the freshly-released versions of the English, Chinese, Japanese, and Korean software:
At the ACE Lab Webinar on the Modern Challenges in Data Recovery & Digital Forensics, our technical engineers showed the features available with the PC-3000 Version 7.0.x., for example, TLER (time-limited error recovery) for WD HDD, the Data Extractor error-processing scenario, and the support of new NVMe drives based on Marvell 88SS1093 controller. These features and more are now available in the latest version of the PC-3000 Software: 2ff7e9595c
