Software Failures

NTFS/ext4 file system damage

Cause: Power failure, unexpected disconnection, OS error

•Windows reports 'Disk is not formatted, do you want to format it?'
•Partition shows as RAW instead of NTFS
•System requests disk check on every startup
•Files are visible but cannot be opened

Data deleted from recycle bin or Shift+Delete

Cause: Unintentional deletion by user

•Data not in recycle bin or original folder
•Important files missing after emptying recycle bin
•Entire folders with documents or photos deleted

Disk partition reformatted

Cause: Error during OS installation, disk confusion

•Disk is empty after Windows/Linux installation
•Wrong target disk during formatting
•File system change (NTFS to exFAT)

MBR/GPT partition table damage

Cause: Software error, virus, failed conversion

•Disk doesn't appear in system at all
•BIOS sees disk but Windows doesn't
•Disk Management shows 'Uninitialized disk'

Hardware Failures

Damaged read heads

Cause: Physical drop, shock, material fatigue, manufacturing defects

•After drop, disk behaves differently, makes different sound (clicking) and reports problems
•Disk won't spin up after drop, system doesn't detect it
•Disk spins up audibly but errors occur when reading data
•Computer shuts down and restarts when trying to turn on
•Media is suspiciously loud

Damaged platter surface

Cause: Physical drop, shock, material fatigue, contamination

•Disk spins up audibly but errors occur when reading

Bad sectors

Cause: Platter wear

•Damaged disk is detected by BIOS and makes clicking or grinding sounds. Data is lost. System or installed utility reports bad sector problems.

Seized bearings - heads stuck on platters

Cause: Manufacturing defects

•Disk audibly tries to spin up but PC quickly shuts down and restarts
•Disk doesn't spin at all, dead silence

Damaged PCB electronics

Cause: Power surge, short circuit, static electricity

•Disk doesn't react at all when connected
•Burning smell from electronics
•Visible damage on PCB board

Important Information

⚠️Don't attempt DIY repairs - you risk permanent data loss
⚠️Don't run disk repair tools (CHKDSK, fsck) on physically damaged disks
⚠️Don't open the disk - clean room environment required
⚠️Don't shake or tap the disk hoping to 'fix' it
