SSD, HDD, External Hard Drive, and Deleted File Review
Data Recovery in Beylikdüzü: SSD, HDD and External Hard Drives
Beylikdüzü data recovery The service includes identifying the type of failure and evaluating the appropriate data extraction method in cases such as accidentally deleted files, data loss after formatting, RAW file systems, corrupted disk partitions, computers that won't boot Windows, inaccessible external drives, and undetected SSD/HDDs .
If data loss is noticed, do not write new files to the disk, do not format or initiate a Windows installation, do not install recovery software on the same disk , and do not repeatedly run the HDD that is making abnormal noises. Each new write and unnecessary operation attempt can affect the recoverable space.
01
Deleted file
Usage and overwriting after erasing are evaluated.
02
Format or partition loss
The file system, partition table, and new data writing are examined.
03
RAW or access error
The disk is detected, but the file system may not be able to open.
04
Disk not visible
The connection, electronics, firmware, and physical faults are separated.
05
Encrypted storage
BitLocker, device encryption, and the recovery key are checked.
Identifying the Type of Failure
Logical data loss and physical disk failure are not the same.
If the disk is stably detected by the operating system but files are inaccessible, a logical problem may be suspected. If the disk makes abnormal noises, disconnects, or is not detected at all, a physical, electronic, or firmware-related failure should be considered.
Physical, electronic, or firmware failure
- Clicking, scraping, or repetitive noises coming from the HDD
- Disk not spinning or constantly disconnecting
- SSD or HDD not showing up in BIOS
- Marks from trauma, liquid contact, or burns.
- SSD controller or NAND communication problem.
- The disk capacity appears incorrect or as zero.
HDDs making abnormal noises should not be scanned with software or run repeatedly . In the event of a possible mechanical failure, standard scanning may increase the risk of additional surface damage.
Data Recovery Review Process
In what order are storage units evaluated?
The goal is to determine the data state by performing as few operations as possible on the source disk , identify priority files, and, where appropriate, continue the work on the copy or image.
01
Storage type and event history are retrieved.
The type of SSD, HDD, external hard drive, or USB memory stick is monitored; information about deletion, formatting, impact, liquid contact, sound, and recent operations is also collected.
02
The behavior of the source disk is observed.
Detection, capacity, connection stability, abnormal noise, temperature, and SMART alerts are monitored within the supported scope.
03
Data priority and encryption are determined.
The folders to be recovered first, file types, user account, BitLocker status, and recovery key status are clarified.
04
An image or controlled copy is taken when appropriate.
If the source disk is unstable, instead of directly scanning the file system extensively, transferring readable sectors to the target disk is considered.
05
File system analysis is performed on the copy.
The partition table, file system, folder structure, and raw file signatures are examined according to the type of data loss.
06
The recovered files are transferred to a separate target disk.
No data is written to the source disk. File listing and openability checks are performed on a separate target, to the extent possible.
Deleted File Recovery
What determines whether deleted files can be recovered?
Deleting a file often doesn't mean the contents are instantly and physically destroyed. However, the file space becomes available for new data, and subsequent use changes the outcome.
Use after wiping
Installing new programs, downloading files, performing updates, or continuing to use the system may overwrite the old data area.
File system structure
NTFS, exFAT, FAT32, and other file systems may handle deleted records differently.
File fragmentation
If a large file is spread across different sectors, finding all the pieces and assembling them in the correct order can be difficult.
File name and folder structure
Even if the content can be found, the original file name, date, or folder structure may not always be preserved.
The TRIM effect on SSDs.
The TRIM command can cause the deleted blocks to be cleared by the controller , severely reducing their recoverability.
No definitive result can be promised.
The possibility of recovery depends on the method of erasure, disk type, encryption, and subsequent write operations.
Format and Section Loss
Why can data sometimes be found after formatting?
Quick formatting can recreate file system records , but it may not instantly reset all data blocks. Subsequent Windows installations or file writing may overwrite the old data.
Quick Format
The file system structure is renewable; some of the old content may remain in physical space until data is written over it.
After Windows installation
System files, updates, drivers, and user profiles can overwrite old data areas, which can reduce the recovery success rate.
Deleted section
Even if the partition table is lost, the data structure can still be found on disk. Creating or formatting a new partition requires additional changes.
Formatting with a different file system
Rebuilding with NTFS, exFAT, or another file system may modify some of the old metadata structure.
The entire disk space is scanned.
If the folder structure cannot be found, a raw scan based on file signatures may be necessary; results may come from unnamed or mixed folders.
The source disk should not be used.
When formatting is detected, shutting down the system and stopping writing to the disk helps to preserve potential data areas.
RAW Disk and File System Error
If the disk is visible but displays a "you need to format it" warning
The operating system may recognize the partition as RAW, be unable to assign a drive letter , or display an access denied error. In this case, formatting should not be performed directly.
RAW file system
If the file system structure cannot be read, Windows may display the partition as RAW.
Section table disruption
Even if the disk capacity is visible, the partition start and end information may be missing.
File record structure
If the NTFS master file table or backup records are corrupted, access to the folder structure may be lost.
Reading error
A symptom that appears to be a file system error may also be caused by a physical sector read problem.
the Cancel option when the warning says, “You need to format the disk before you can use it .” Formatting and write operations like CHKDSK can modify the data structure.
HDD Physical Failure Symptoms
Why are clicking, rubbing, or repetitive sounds important?
Mechanical HDDs contain rotating platters and moving read-write heads . In the event of a physical failure, each attempt at operation can affect the surface and head condition.
Regular clicking sound
The head's reference search, servo reading problem, or firmware startup issue can cause repetitive clicking.
Rubbing or scraping sound
The disc should be turned off and not restarted. Contact with the platter surface could cause further damage.
The disc is not spinning.
as motor, electronic circuit board, power connection, or internal mechanical jams are assessed.
Frequent disconnections
Aside from the cable and enclosure, a weak connector, a faulty sector, or a power or controller issue can also cause the connection to be lost.
Incorrect appearance of capacity
Firmware translation table, service area, or electronic problems can prevent the disk's true capacity from being read.
Laboratory conditions required
For malfunctions requiring intervention on the head, motor, or internal mechanics, controlled laboratory conditions may be necessary; standard workshop opening procedures should not be applied.
SSD Data Recovery
Why are different methods needed for SSD failures?
SSDs have no moving parts. Data is stored in NAND memory; the controller, firmware, translation table, encryption, and TRIM behavior directly affect data access.
Controller malfunction
The SSD may not appear in the BIOS, may display an incorrect capacity, or may be detected briefly and then disconnected.
NAND memory wear
Reading errors, critical health alerts, and switching to read-only mode may be related to the state of memory cells.
Firmware and translation table
the mapping of logical addresses to physical NAND areas is disrupted, disk capacity or file structure may become inaccessible.
TRIM and garbage collection
Clearing deleted blocks in the background can reduce the likelihood of recovering deleted files.
Hardware encryption
In some SSDs, data is encrypted via the controller. Simply reading the NAND chips may not produce meaningful data.
Integrated storage
In modern ultrabooks and some Apple devices, storage is integrated into the motherboard; data access may depend on how the device is operating.
External Hard Drive and USB Storage
If the external hard drive isn't detected, is the problem always with the internal hard drive?
The external enclosure's USB-SATA converter, cable, USB port, or power adapter may be faulty. However, if abnormal sound or connection drops, simply replacing the enclosure and repeatedly trying again should not be the only solution.
USB cable and port
Connection behavior can be compared in a controlled manner using different robust cables and suitable USB ports .
External box electronics
If the USB-SATA bridge card is faulty, the disk inside may not be recognized by the computer even if it is healthy .
Power adapter
With 3.5-inch external hard drives, an inadequate or faulty adapter can prevent the drive from spinning and being detected stably.
Internal disk failure
If the enclosure and cable are intact, the mechanical fault of the HDD or SSD will be assessed.
Image Acquisition and Copying
Why isn't a direct, intensive scan performed on the source disk?
The goal with unstable or faulty disks is to transfer readable data to another target with as few repetitions as possible. File system analysis can then be continued on the copy.
Source disk protection
Instead of repeatedly reading the same regions, an error-handled transfer approach can reduce unnecessary disk work.
Sector-based image
If appropriate, readable sectors of the disk are transferred to an equal or larger target; corrupted areas can be recorded.
Priority areas
If the disk is rapidly degrading, important file system regions or user-specified data areas can be prioritized.
The source and the target must be separate.
The recovered files are not written to the faulty source disk; a different target storage device with sufficient capacity is used.
Image is not a guarantee of success.
Unreadable, encrypted, or overwritten areas may also be missing from the copy.
File analysis is performed on the copy.
Partition repair, file system scanning, and file signature searching are performed on the image rather than the source whenever possible.
BitLocker and Device Encryption
Why is a recovery key necessary for an encrypted disk?
Even with BitLocker or device encryption enabled, reading raw sectors doesn't automatically mean files can be viewed directly. Contents may be undecryptable without a valid key or user authentication.
48-digit recovery key
A Microsoft account can be a work account, a printed document, or registered within an organization's management system.
TPM and motherboard relationship
If the switch is connected to the TPM, a motherboard or BIOS change can trigger the recovery screen.
Decryption is a separate process.
Even if the disk is physically readable, unlocking the encrypted volume requires the correct key and intact metadata.
No password guessing is possible.
Your user account password and your BitLocker recovery key are not the same thing.
Corporate devices
The key can be stored in the company's IT department, in an Entra ID/Active Directory account , or in the device management system.
The outcome may be limited if the key is missing.
can prevent file access even if the storage is physically healthy .
How to retrieve data from a computer that won't boot up (Windows)
If your computer doesn't turn on, it doesn't necessarily mean your files are lost.
While the motherboard, screen, or Windows startup problem might be the issue, the storage unit could be healthy. First, the disk's structure, encryption, and whether it's integrated with the device are determined.
Removable SATA or NVMe disk
A healthy, unencrypted disk can be read independently with a suitable adapter or testing system.
Windows is corrupted, but the disk is healthy.
User folders can be accessed from a different environment before the operating system starts.
Motherboard integrated storage
If the storage unit cannot be removed, the device may need to be temporarily or permanently made operational.
User permissions
Windows file permissions can generate access warnings on different systems; this should not be confused with encryption.
Microsoft account and key
If device encryption is automatically enabled, the recovery key can be found in your Microsoft account.
First the data, then the setup.
Windows installation or disk formatting without securing important files .
Checking the Recovered Files
Does the file appearing in the list mean it's valid?
The file name and size may be found, but the content may be incomplete, overwritten , or corrupted. The openability of the recovered data is assessed by sampling and integrity checks based on the file type.
Openability check
Photographs, documents, videos, or archive files are opened and checked using appropriate programs.
File size
Zero bytes, unexpectedly small size, or missing blocks can be an indication of a corrupted file.
Folder structure
If metadata is preserved, the original folders and names can be found; in raw scans, files can be separated by type.
Target disk
The recovered data is copied to a different, healthy target storage device with sufficient capacity than the source disk.
Data Access and Processing Scope
What information is requested from the user during the review process?
Data recovery may require technical access to file contents. Priority folders, encryption key, and scope of delivery must be clearly defined upon device acceptance.
Priority data list
Documents, photos, accounting files, projects, or specific date ranges are listed in order of priority.
Password and recovery key
This setting is only provided by the user when necessary; the user may be offered a change after the process is complete.
Target storage
An external hard drive or SSD suitable for the amount of data to be recovered can be provided or specified by the user.
File verification scope
It may not be possible to open all of the numerous files individually; samples of the most important file types will be used.
Delivery of the source disk.
Once the process is complete, the source disk and the recovered data are delivered to the user according to the delivery terms.
The result depends on the nature of the malfunction.
Encrypted fields that have been overwritten, are physically unreadable, or for which the key cannot be found may not be recoverable.
Guidance Based on Symptoms
Which data recovery approach should be considered in which situation?
The table below is not a definitive solution. It shows the initial check to be performed and the action to be avoided, depending on the symptom.
Symptom
Priority approach
Things to avoid
The files were deleted accidentally.
Stopping disk usage, determining write status after erasing.
Installing programs or downloading files to the same disk
The disk has been formatted.
Stopping new data writing and performing file system analysis.
Windows installation and reformatting
The disk appears to be RAW.
Examine disk health and file system structure via a duplicate copy.
Formatting and uncontrolled CHKDSK
The HDD is making a clicking sound.
Turn off the device and assess the level of physical failure.
Repeated opening, surface testing, and long-term scanning.
SSD is not showing up in BIOS.
Connection, controller, firmware, and electronic fault differentiation.
Random firmware and continuous power supply.
The external hard drive is disconnecting.
Comparing the behavior of the cable, enclosure, power supply, and internal disk in a controlled manner.
Intensive copying and repeated insertion and removal.
A BitLocker key is required.
Finding the recovery key from your Microsoft or corporate account.
Resetting the TPM and formatting the disk.
Windows won't start, but the disk is visible.
First, place the important files in a separate target location.
Clean installation without data verification.
Transactions and Fees
Why isn't the data recovery price a single digit?
Scanning for deleted files and repairing a physically faulty HDD or undetected SSD do not require the same equipment, time, or processing level. Pricing is determined by the storage type, capacity, failure level, and the method to be applied.
Storage type and capacity
The type of storage device—HDD, SATA, SSD, NVMe, external hard drive, or integrated storage— affects the processing method and duration.
Logical or physical failure
File system analysis is not the same as electronic, firmware, or mechanical intervention.
Image acquisition time
On faulty or slow-reading disks, sector-based data transfer may take a long time and may be interrupted depending on the disk behavior.
Data volume and file structure
Millions of small files, large archives, or corrupted video structures can affect the verification process.
External laboratory requirement
Situations requiring special conditions, such as internal mechanical HDD repair, may necessitate separate evaluation and incur additional costs.
The outcome of the rescue is not predetermined.
No percentage or file quantity promises can be made without a review; disk readability determines the outcome.

Frequently Asked Questions
Frequently asked questions about data recovery in Beylikdüzü.
Is it possible to completely recover deleted files?
No. The result depends on the disk type, TRIM, encryption, erasing method, and how much new data is written to the disk after erasing.
Can files be recovered after formatting?
In some cases, it may be possible. New Windows installations, file copying, and formatting all affect the recoverable space.
Is it possible to recover files deleted from an SSD?
On SSDs, TRIM and background cleanup operations can quickly render deleted blocks inaccessible. No definitive results can be given without an investigation.
What should be done if there is a clicking sound coming from the hard drive?
The disk should be turned off and not repeatedly turned on. Software scans or surface tests should not be performed in the event of a possible mechanical failure.
Is it necessary to format the RAW disc?
No, if there is important data. Formatting can change the file system structure; disk health and data status should be checked first.
Is it possible to retrieve files from a computer that won't boot up in Windows?
This is possible if the storage unit is healthy and accessible. BitLocker affects integrated storage and disk failure methods.
Is it possible to retrieve data without a BitLocker key?
, accessing the file contents may not be possible without the correct recovery key .
Are the recovered files saved to the same disk?
No. To avoid overwriting the source disk, the recovered files are transferred to a different target storage device with sufficient capacity.
How long does data recovery take?
The duration varies depending on capacity, read speed, amount of corrupted space, type of failure, image acquisition, and file verification needs.
Will all my files be checked individually?
With a very large number of files, it may not be possible to open each file individually . Sampling is done using priority folders and important file types .
