Data Recovery Service Dhaka — Hard Drive, SSD & Memory Card Recovery 2026

1 July 2026 · 14 min read · BAYAS Editorial

Data recovery service in Dhaka from BAYAS Computer Service recovers lost files from hard drives, SSDs, USB flash drives, and memory cards — with a written no-recovery, no-charge guarantee. Certified technicians serve all 36 Dhaka zones via home visit or workshop drop-off. Logical recovery (deleted files, formatted drives) starts at BDT 2,000; cleanroom hard drive recovery starts at BDT 12,000. Free diagnosis within 24 hours.

If you just lost important files — years of family photos, business documents, your university thesis, or client contracts — take one action before anything else: stop using the device immediately. Every write operation to a failing drive, every restart, every software install overwrites sectors that may hold your data. The single most important variable in data recovery is time — and what you do (or do not do) in the first hour.

This guide explains what data recovery actually involves in Dhaka, what you can realistically expect to recover, how BAYAS handles every device type, and what recovery realistically costs in BDT.

For detailed pricing across every failure type and device category, see our Data Recovery Cost Guide for Dhaka.

What Is Data Recovery and When Do You Need It?

Data recovery is the process of extracting files from a storage device that is no longer accessible through normal means. You need professional data recovery when:

A hard drive makes clicking, grinding, or beeping sounds (physical head failure)
A drive is not detected by your PC or laptop (PCB failure, seized motor, or SSD controller failure)
You accidentally deleted files or reformatted the wrong drive
A drive was dropped, flooded, or electrically surged
An SSD shows up as the wrong capacity or as an "Unknown Device"
A memory card or USB drive returns errors like "Please insert disk" or "Drive not formatted"
Files open as corrupted or unreadable even though the drive is detected

Key fact: BAYAS Computer Service has handled 5,000+ device repairs since 2018, including hundreds of data recovery cases across Dhaka — from simple deleted-file recovery to full cleanroom head replacements.

What Types of Storage Devices Can Be Recovered?

BAYAS recovers data from every common storage device used in Bangladesh:

Device	Failure Types Handled	Recovery Approach
Internal HDD (2.5" / 3.5")	Logical, bad sectors, PCB damage, head crash, motor failure	Software imaging → PCB repair → cleanroom
External HDD (portable/desktop)	Physical drop, PCB short, USB bridge failure	PCB swap, USB bridge replacement, cleanroom
SATA SSD	Controller failure, NAND wear, firmware corruption	Controller bypass, JTAG, chip-off NAND reading
NVMe / M.2 SSD	Controller failure, encryption issues, solder joint failure	Chip-off, JTAG, NAND programmer
USB flash drive / pen drive	Logical, broken connector, controller failure	Solder repair, NAND programmer
SD / microSD / CF card	Logical, physical damage, controller failure	Software + NAND programmer
RAID arrays (0/1/5/6)	Drive failure, controller corruption, accidental reformat	Virtual rebuild + logical extraction
Mobile phone internal storage	Encrypted NAND, chip-off	JTAG, ISP, chip-off (requires unlock)

How Does Data Recovery Work? The BAYAS 6-Step Process

Step 1 — Free Consultation (WhatsApp or Phone)

Call or WhatsApp 01712-644590 and describe the failure. Tell us: what sounds the drive makes, what error message you see, what happened just before the failure (drop, power cut, water, sudden shutdown). We give you an initial assessment immediately and tell you whether the case is recoverable.

Step 2 — Diagnosis (Free, Within 24 Hours)

Our technician evaluates the device using professional tools — PC-3000 Portable for HDDs, PC-3000 Flash for SSDs and flash storage, and specialist programmers for chip-level work. The diagnosis identifies the failure mode and gives you a realistic success probability.

Step 3 — Firm Quote and Approval

You receive a firm BDT quote before any recovery work starts. You decide whether to proceed. There is never any pressure.

Step 4 — Recovery

We apply the right method for the failure:

Logical failures (deleted, formatted, corrupted): software imaging and file carving
Firmware corruption: firmware area repair using specialist tools
PCB damage: donor PCB sourcing and board-level repair
Cleanroom recovery (clicking drive, head crash): donor head replacement in our Class 10 laminar-flow environment
SSD failure: chip-off NAND reading and NAND reconstruction

Step 5 — Verification

We verify that recovered files open correctly and are not truncated. You review the file list before we copy anything.

Step 6 — Delivery

You receive data on a new external drive or USB flash drive. We wipe our work copy after handover. A 30-day warranty covers the delivery media.

Hard Drive Data Recovery Dhaka — What to Expect

Hard drives are the most common recovery case BAYAS handles in Dhaka. HDDs fail in several predictable ways:

Logical failure — The drive physically spins and is detected by the BIOS, but files are missing or inaccessible. Causes: accidental deletion, formatting, virus attack, partition table corruption, power surge that scrambled the file system. This is the most recoverable category. Success rate: 90–95%.

Firmware failure — The HDD firmware (stored on the platters or in ROM) is corrupted. The drive may spin but not communicate properly. Symptom: drive detected as 0 MB capacity, "BSY" state, or unusual model string. Requires specialist firmware tools. Success rate: 80–90%.

Bad sector / mechanical wear — The drive spins but reads slowly, throws errors, or freezes during file access. Surface of the platters has degraded areas. Professional imaging tools (like DeepSpar Disk Imager) work around damaged sectors to extract as much data as possible. Success rate: 60–85% depending on extent of damage.

PCB failure — The circuit board attached to the drive's base is burnt or short-circuited (common after power surges or lightning strikes in Bangladesh). The drive does not spin or is completely undetected. Requires a matching donor board — not a simple swap; ROM chip data must be transferred. Success rate: 70–85%.

Head crash / clicking drive — The read/write heads have physically contacted the platters. The drive makes a clicking, grinding, or beeping sound. This is an emergency — do not power the drive on again. Head replacement in a cleanroom is required. Success rate: 50–80% depending on how long the drive was run after the click started.

⚠️ Important: If your hard drive is clicking, grinding, or making repetitive tick-tick sounds, shut it down immediately and contact BAYAS. Every power cycle risks further platter scratching, which reduces recovery chances significantly.

SSD Data Recovery Dhaka — Why It Is Different

SSD recovery is fundamentally different from HDD recovery. There are no moving parts to replace — instead, the challenge is the SSD controller chip and NAND flash architecture.

Why SSDs are harder to recover:

Encryption — Most modern SSDs encrypt data at rest by default (AES-256). If the controller fails, the encryption key is lost with it, making the NAND chips unreadable.
Wear levelling — The controller deliberately moves data around to extend NAND lifespan. This means files are scattered across hundreds of physical blocks in a non-linear pattern.
TRIM — When you delete a file on an SSD (or format it), TRIM tells the controller to zero out those blocks immediately. This significantly reduces — but does not eliminate — software recovery chances.

What BAYAS can do for a failed SSD:

Firmware recovery for SSDs stuck in "busy" or "busy idle" state
Controller bypass for specific common failure modes (e.g., Phison, Silicon Motion, Marvell controllers)
JTAG and ISP recovery for mobile and embedded NAND
Chip-off NAND reading using NAND programmers (when NAND chips themselves are intact)

The honest answer on SSD recovery: it is more expensive, takes longer, and has lower success rates than HDD recovery. Prevention is far better — back up your SSD regularly. If it fails, bring it to us immediately without further power cycles.

Memory Card & USB Flash Drive Recovery Dhaka

Memory card and USB recovery are the fastest and most affordable recovery cases:

Common causes:

Removed without safely ejecting → logical corruption
Water or physical damage to the card or connector
"Not formatted" or "Please insert disk" error despite the card being present
Camera shows "Card Error" after a power cut during write

What BAYAS does:

Software logical recovery for simple cases (BDT 2,000–4,000)
Connector repair / PCB-level repair for physically damaged USB drives
NAND chip-off reading for controllers that have completely failed
Card reader compatibility testing (sometimes the reader, not the card, is the problem)

For cameras, phones, and action cameras — bring the card and the device together so we can test compatibility before recovery.

Common Data Recovery Mistakes to Avoid

:::warning Stop. Do not do any of these before calling BAYAS. :::

Powering a clicking hard drive on and off repeatedly — Each spin cycle causes more platter damage
Installing recovery software on the failing drive — The installer overwrites the very sectors you want to recover
Formatting and reusing the drive after accidental format — New writes immediately overwrite deleted data
Putting the drive in the freezer — This 1990s trick causes condensation damage on modern drives and almost never works
Opening the hard drive — HDDs are assembled in Class 100 cleanrooms. Dust from a typical Dhaka room will scratch the platters permanently
Using a free online "recovery tool" — Many are malware. Those that are legitimate only work on logically healthy drives
