How to Recover Data from a Dead or Failing Hard Drive

2026-10-13 · 8 min read

A hard drive can fail in different ways, and the type of failure determines what you can do about it. Some failures are fixable at home with free software. Others require a professional with the right tools. The worst thing you can do is keep trying random fixes on a dying drive, because every power cycle and read attempt can make the damage permanent.

Signs the drive is failing vs. already dead

Failing (data likely recoverable)

• The drive is detected in BIOS or Disk Management but is very slow to read
• You hear occasional clicking or grinding, but the drive still spins up
• Windows shows errors like "The request could not be performed because of an I/O device error" or "The file or directory is corrupted and unreadable"
• Some files open normally while others are corrupted or missing
• SMART data shows reallocated sectors, pending sectors, or uncorrectable errors above zero

Dead (may need professional recovery)

• The drive does not spin at all when powered on
• Loud repetitive clicking immediately on power (the head is stuck or damaged)
• The drive is not detected by any computer or USB adapter
• A burning smell or visible damage to the circuit board
• The drive was dropped, submerged, or exposed to extreme heat

What to do first

Stop using the drive immediately. Do not run chkdsk, defragment, or attempt to reinstall Windows on it. Every write operation can overwrite data you want to recover. If the drive is currently your boot drive, shut the computer down and remove it.

Connect the drive to a working computer as a secondary drive using a USB-to-SATA adapter, a USB drive dock, or an internal SATA cable. This lets you attempt recovery without writing to the failing drive.

Software recovery (for drives that are still detected)

If the drive appears in Disk Management or the BIOS, even if Windows cannot read it normally, software recovery tools can often pull files off it:

1. Connect the drive as a secondary device, never as the boot drive
2. Use a recovery tool that reads the drive sector by sector. Free options include Recuva and PhotoRec. Paid tools like R-Studio and DMDE handle more complex corruption
3. Save recovered files to a different healthy drive, never back to the failing one
4. Prioritize the most important files first. If the drive is degrading, it may stop responding partway through

For an SSD that is not detected at all, firmware failure is a common cause. Some manufacturers offer firmware recovery tools, but these are model-specific and not always available.

When software will not work

If the drive clicks loudly and repeatedly, does not spin up, or is not detected by any computer, the failure is likely mechanical or electrical. In these cases:

• Do not open the drive. Hard drive platters must be handled in a clean environment. Dust particles are larger than the gap between the read head and the platter surface. Opening a drive on a kitchen table usually makes recovery impossible
• Do not freeze the drive. This was sometimes suggested for older drives with stiction problems. On modern drives it causes condensation damage and makes things worse
• Do not hit or shake the drive. A stuck head can sometimes be freed, but not by impact. This usually scratches the platter

Professional data recovery labs can replace failed heads, swap circuit boards, and image platters in clean rooms. This is expensive, typically $500 to $1,500 or more depending on the damage, and there is no upfront way to know if recovery will succeed.

Preventing this next time

• Automate backups. Windows File History, macOS Time Machine, or a scheduled copy to an external drive means a failed drive is an inconvenience, not a disaster
• Use cloud backup for irreplaceable files. Photos, tax documents, and business records should exist in at least two places
• Watch SMART warnings. Tools like CrystalDiskInfo (Windows) or DriveDx (macOS) can alert you when a drive starts showing early signs of failure, giving you time to copy data off before it dies
• Replace spinning drives proactively. A hard drive older than five years with daily use is living on borrowed time. An SSD has no moving parts and is far less likely to fail without warning
