Hard Drive Data Recovery Tool

[Kylee Evancho]

Questionsseeking product, service, or learning material recommendations are off-topic because they become outdated quickly and attract opinion-based answers. Instead, describe your situation and the specific problem you're trying to solve. Share your research. Here are a few suggestions on how to properly ask this type of question.

My computer has stopped working because the hard disk has broken. I used it to store important data without having a backup, and several files (.xslx, .word, .pdf) could not be recovered or they are corrupt when we use a program to access it. Is there any other way to try to recover them?

If your data has value, go to a pro. Most recoveries, even those requiring clean room work do not exceed say $850 but some labs are in to $300 - $500 range even if clean room is required and if no additional parts need to be sourced.

Many failed DIY attempts may hamper recovery and add to the price. This is true if the data loss has a physical cause and if in-place repairs are attempted (partition table editing, rebuild RAID etc.).

With sudden data loss a physical cause should not be ruled out before hand, even if the damage appears to be at the logical level. For example, a RAW file system can be due to logical corruption, it is however also a common symptom for physical damage. Even just repeated read attempts can further damage a drive or cause firmware damage (g-list overflow).

It does not hurt to use a S.M.A.R.T. utility. Although the information may be overwhelming it can be useful. Treat information as such: If the SMART tool alerts you about problems then assume there are in fact problems. However, absence of alerts does not mean the drive is okay by definition.

If raw values are non zero the drive had, at some point, problems reading sectors. Large values IMO (say > 20) are alarming even if the SMART tools says they are not. An easy to use and free SMART tool is CrystalDiskInfo. In menu Function > Advanced Feature > set RAW values to 10 [DEC]. Most of the file recovery tools I'll recommend later on also can display SMART data.

It is true that SSD's are less prone to mechanical damage of moving parts. Still, sudden disappearance of data can have physical causes such as sudden loss of power. SSD's can and do suddenly fail just like conventional hard drives.

Also SSD's can experience 'bad sectors' although these are of an entirely different nature than bad sectors on spinning disks. Such bad sectors can have cascading effects and SSD's, once they start behaving odd or unstable can deteriorate rapidly. A a lab is not an option and you need more than a few files, skip to cloning.

TRIM is often misunderstood. it's is important to understand that TRIM is a command that is sent by for example the operating system to inform the SSD drive about a range of sectors that can be discarded. TRIM is not file deletion of erasure in itself.

It depends on a specific OS if and when it sends TRIM commands. One OS may send a TRIM command immediately if for example a file is deleted, the other may schedule weekly TRIM commands, or an OS may do both.

For example Windows sends a TRIM command when you format a partition or as soon as you delete a file - if it concerns a NTFS formatted volume. So, in general data recovery from a formatted partition is impossible unless: 'circumstances' (non 'supported' file system, older USB bridge not relaying TRIM commands, etc.).

If you however you can not access the partition because the file system is RAW, this is no reason for Windows to 'TRIM' that partition and in general one can assume the data can be recovered. So in general, an OS will only TRIM data that is purposely deleted.

TRIM =/= erasure, or zero-fill although it may appear that way. In short: Many controllers 'unmap' trimmed LBA addresses. Try reading such LBA addresses and the controller simply returns zeros without even ever reading the drive. A data recovery lab may be able to recover 'trimmed' data while a data recovery lab can not recover data that was truly overwritten, even if only overwritten with zeros.

Can be used to make some in place repairs where it concerns MBR, partition tables and boot sectors. These are a tiny fraction of all things that can be wrong and prevent access to your data, and in general it's a bad idea to make in-place repairs. That said, for a knowledgeable person patching a disk can be the quickest way to recovery with only marginal risks.

Also reason for data loss plays a role: If the known cause is accidental partition deletion, and the layout of the disk is known, picking the correct partitions isn't rocket science and fairly low risk IMO. If on the other hand cause for the data loss is unknown it makes no sense to try TestDisk just for the sake of it.

Partition undelete/recovery only makes sense if partitions are not visible, not if new partitions were already created and formatted. Boot sector repair only makes sense if the issue is actually the boot sector.

Even though these tools are designed for this and good at what they do (specially HDDSuperClone), if cloning/imaging is problematic (drive disappears randomly, extremely slow, noisy) it's wise to stop DIY attempts.
