The advanced technology brings convenience to life together with risk along with if there was anything bad happened to the disk, like what, crash?

When hard drive crashes happen, it often caused by issues listed as below: system failure/human operation, mechanical failure.

  4. Hard drive is making noise and the light is blinking - it is going to die soon, or wont boot already
  5. It takes much longer time for accessing files&folders - it is getting corrupted (bad sector or disk damage)
  6. “X:\ is not accessible. The file or directory is corrupted and unreadable” - can be repaired with cmd
  7. The type of file system is raw, Chkdsk is not available for RAW drives - logical failure, can be fixed

System/logical failure - can be repaired by tool

Mostly such logical failure were brought by human operations or other logical corruption that can be repaired by some tools. For instance, accidental formation or deletion will cause disappearing folder or files, data can be retrieved under such circumstances.

  2. "/r" is for locating and recovering information from the bad sectors of the hard drive.
  3. "/x" is for dismounting the drive prior to the starting of the process of repairing the drive

Bad Sectors on hard drive - can we use chkdsk for repairing bad sectors?

Bad sectors were determined by the use of your disk that comes naturally for years of data saving. It often brings damage to hard disc paltters and it made file corruption.

Many users try to deal with it by running utilities like Scandisk and Chkdsk. These utilities attempt to identify bad sectors, allowing hard drives to run more efficiently. While this process occasionally fixes minor corruption, disk utilities can contribute to media damage. If the read/write heads of a hard drive are in contact with the platters, running a utility will damage the magnetic material that stores your files.

You may run chkdsk to repair bad sectors if there were nothing important on the disk, or we wont suggest an operation of chkdsk or any repair utlity to fix the disk if there were important data.

Knowedge about Bad Sector

A bad sector is a sector on a computer's disk drive or flash memory that is either inaccessible or unwriteable due to permanent damage, such as physical damage to the disk surface or failed flash memory transistors. Bad sectors are usually detected by a disk utility software such as CHKDSK or SCANDISK on Microsoft systems, or badblocks on Unix-like systems. When found, these programs may mark the sectors unusable (most file systems contain provisions for bad-sector marks) and the operating system skips them in the future. Under such circumstances, data recovery can not be performed to the part where damaged partition occurred with or without a recovery software.

Hard drive failure causes

Why the hard drive failed or crashed? There are many reasons of such damage.

  1. Logical damage: usually such damage can be repaired when the hard disk suffered logical damage for eg: lost/corrupted partition table, bad sectors, damaged MBR, system error, bootable error, unknown file system, logical error, disk is not formatted, do you want to format it now, raw file system, virus damage, Read/Write Head Tracking Issues...
  2. Physical damage: burned/damaged disc, damaged header, short-circuit failure, corrutped chip, water damage... dropped off from high location...
  3. Improper operations: sudden power failure, removed without safe removal, shut down system improperly, third-party software damage like partition magic

Corrupted Hard Drive Stories and Recovery Guide for Each

A: Hard drive corrupted unformatted and shows file system is raw in disk management

“My computer holds 2 hard drives, one 2TB seagate hard drive and the other one is samasung ssd of 1TB which holds my system Windows 10 . The 2TB hard drive got corrupted on the partition H which is showing as unformatted (corrupt). I did not format it when it pompts up the format message to me and when I go to disk management, it shows as RAW in file system. I tried i chkdsk on the drive, but got error “Chkdsk is not available for RAW drives”.

--user from a forum on Techtarget

Resolution:

The hard drive of 2tb seagate disk has suffered logical damage which can be repaired without formatting. Recover the inside data, repair with cmd.

B: Hard drive stopped working and it is unreadable

My 120GB hard drive recently stopped working. I didn't hear any noise--it just stopped working.

I put another hard drive in the machine and set it up with OS and applications, and then put her old drive in as a slave and tried to look at it, but a message comes up that says it's unreadable. Other attempts say the hard drive is corrupt.

-- user from CNET forum

Resolution: Connect the disk to another PC as a slave drive, clone the damaged hard drive at first and then Go to This PC (right-click) > Manage > Disk Management. Right-click your hard drive and click Change Drive Letter and Paths

If this one does not work, then recover the data at first, you may clone the damaged disk to another new disk with 1-1 sector clone. And then try chkdsk, or error-checking.

Knowledge about Hard Disk Drive

A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. [2] Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile storage, retaining stored data even when powered off. -see wiki
