Most people think recovering data from any hard drive is the same. But it’s not. SSDs and HDDs are built differently—and so are the techniques required to recover lost data. At Rainbow Computers, we’ve successfully handled both types. Here’s what you should know.
How They’re Built
HDD: Mechanical parts — spinning platters, magnetic heads, moving arms.
SSD: No moving parts — uses NAND flash memory chips, faster and silent.
Common Failure Scenarios
| Type | Common Issues | Recovery Challenge |
|---|---|---|
| HDD | Head crash, motor failure, bad sectors | Needs cleanroom, physical part replacement |
| SSD | Controller failure, firmware corruption, NAND wear | Needs specialized tools and chip-level access |
Data Recovery Techniques We Use
- For HDDs:
- Head stack replacement
- PCB swapping
- Sector-by-sector imaging
- For SSDs:
- Firmware repair
- NAND chip off extraction
- Controller emulation
We recovered 98% data from a dead 240GB SSD used in a DSLR editing setup for a wedding photographer. They had no backup. We saved their work within 72 hours.
Cost & Time Comparison
| Factor | HDD | SSD |
|---|---|---|
| Average Time | 2–5 days | 3–10 days |
| Cost Range | ₹2,000–₹6,000 | ₹4,000–₹12,000 |
| Recovery Rate | High (if heads are good) | Variable (depends on chip condition) |
When to Contact a Pro
If your device:
- Isn’t detected by your system
- Makes clicking noises (HDD) or is totally dead (SSD)
- Shows 0MB capacity
👉 Do NOT attempt software recovery. You might lose your data permanently. Contact Rainbow Computers early for the best chance of recovery.
