Losing important files — family photos, business records, university work, client contracts — is one of the most stressful tech problems you can face. The first 30 minutes after data loss determine whether your files are recoverable or gone forever. Understanding the **data recovery success rate in Dhaka** and what to do immediately can save your data.

BAYAS Computer Service has recovered data from thousands of devices since 2018, using professional tools that most repair shops do not have. Our success rates rival international data recovery labs — at a fraction of the cost.

## The First 30 Minutes After Data Loss — What to Do

This is the most critical section of this guide. Every minute you wait or continue using the device reduces your chances of successful recovery.

### Do NOT:
- ❌ **Do not use the device** — every read/write operation can overwrite your data
- ❌ **Do not power on a clicking or beeping drive** — it causes further physical damage
- ❌ **Do not run recovery software on a failing drive** — it stresses the drive and can cause total failure
- ❌ **Do not put the drive in a freezer** — this is a myth that causes more damage
- ❌ **Do not shake or tap the drive** — physical shock damages platters and heads

### DO:
- ✅ **Power off the device immediately** (if safe to do so)
- ✅ **Disconnect all cables** from the device
- ✅ **WhatsApp BAYAS at 01712-644590** — free immediate advice within minutes
- ✅ **Note what happened** — was it dropped, flooded, or did the drive start making noise?
- ✅ **Bring the device to us or arrange home pickup** — BDT 300–500 pickup fee

### Why Timing Matters

When data is "deleted" or a drive "fails," the data is not immediately destroyed. Instead:
- **Deleted files:** The file system marks the space as "available" but the data stays until overwritten
- **Formatted drive:** The index is cleared but raw data remains on the platters
- **Failing drive:** Sectors degrade gradually — each read attempt can lose more data

The longer you wait or use the device, the more data gets overwritten or lost permanently.

## Data Recovery Success Rates by Failure Type

### Logical Recovery (Software-Level Issues)

| Failure Type | Success Rate | BDT Cost | Duration |
|---|---|---|---|
| Accidentally deleted files | 90–98% | 2,000–5,000 | 1–3 days |
| Formatted drive (quick format) | 85–95% | 2,000–5,000 | 1–3 days |
| Formatted drive (full format) | 40–60% | 3,000–6,000 | 2–4 days |
| Corrupted partition | 85–95% | 2,000–5,000 | 1–3 days |
| Virus-encrypted (ransomware) | 30–70% | 3,000–8,000 | 2–5 days |
| RAW/unrecognised file system | 85–95% | 2,000–5,000 | 1–3 days |

**Why the range?** Logical recovery success depends heavily on whether data has been overwritten. A freshly formatted drive with no new data written has a much higher success rate than one that has been reformatted and used for weeks.

### Physical Recovery (Hardware-Level Issues)

| Failure Type | Success Rate | BDT Cost | Duration |
|---|---|---|---|
| Bad sectors (partial) | 80–95% | 3,000–8,000 | 2–5 days |
| Bad sectors (severe) | 60–80% | 5,000–12,000 | 3–7 days |
| PCB failure (burnt electronics) | 85–95% | 4,000–10,000 | 2–5 days |
| Head crash / clicking drive | 85–95% | 12,000–30,000 | 3–10 days |
| Motor seizure (drive not spinning) | 75–90% | 10,000–25,000 | 3–10 days |
| Water/flood damage | 60–85% | 8,000–25,000 | 5–14 days |
| Fire damage | 20–50% | 10,000–30,000 | 5–14 days |

### SSD-Specific Recovery

| Failure Type | Success Rate | BDT Cost | Duration |
|---|---|---|---|
| Logical (deleted/TRIM) | 70–90%* | 2,000–6,000 | 1–3 days |
| Controller failure | 60–80% | 8,000–20,000 | 5–14 days |
| Firmware corruption | 70–85% | 5,000–15,000 | 3–10 days |
| NAND wear (end of life) | 30–60% | 8,000–20,000 | 7–14 days |

*\*SSD TRIM command immediately destroys deleted data in most cases. Success for TRIMmed SSDs drops to 20–40%.*

## HDD vs SSD — Different Recovery Approaches

### Hard Disk Drives (HDD)

HDDs store data on spinning magnetic platters read by mechanical heads. Recovery approaches:

1. **Software imaging** — for logical issues and bad sectors, we create a sector-by-sector clone
2. **PCB repair/replacement** — for electronic failures, we replace or repair the circuit board
3. **Head replacement** — in our Class 10 cleanroom, we swap damaged read/write heads
4. **Platter transplant** — for seized motors, we move platters to a donor drive

### Solid State Drives (SSD)

SSDs store data on NAND flash chips with no moving parts. Recovery is fundamentally different:

1. **Controller bypass** — if the SSD controller fails, we connect directly to NAND chips
2. **Chip-off NAND reading** — we desolder NAND chips and read them with a specialized programmer
3. **Firmware repair** — for firmware corruption, we repair the SSD's internal firmware
4. **JTAG debugging** — for advanced controller-level issues

**Key difference:** SSD recovery requires specialized equipment (NAND programmers, JTAG interfaces) that most labs in Bangladesh do not have. BAYAS maintains professional SSD recovery tools.
