Parts of an external hard drive
An external hard drive is made up of a mechanical hard drive or SSD, an external connection adapter (USB, USB C, Firewire etc) and a plastic or metal casing. There are two types, the 3.5” ones that exclusively carry mechanical hard drives and are of high capacity and the 2.5” ones that can carry both mechanical hard drives and SSDs.
Types of external hard drives
The 3.5” ones, apart from the cable to the computer, need additional power (a transformer), while the 2.5” ones, except for very old disks, allow them to be powered directly from the PC port where it is connected. In 2.5” disks, an additional plate was used between the disk (SATA format) to convert it to USB or similar. Nowadays, manufacturers have created electronic boards with the integrated USB connection to reduce costs.
We are specialists in data recovery from damaged external hard drives with more than 20.800 diagnosed cases. We want to advise you based on our extensive experience.
PROBLEMS WITH AN EXTERNAL HARD DRIVE?
If you encounter a situation similar to this:
- The computer does not start and reports a hard drive failure.
- The drive is making a strange noise or is very slow.
- After a power outage or blackout the hard drive stops working.
- The computer has crashed and the disk has crashed.
- The computer boots but does not recognize the hard drive.
- Unable to access saved videos, photos and/or documents.
- Any other situation not mentioned above.
We can offer you an external hard drive recovery.
Our data recovery service works on any brand of external hard drive: Western Digital, Seagate, Toshiba, Hitachi, Samsung, Fujitsu, LaCie , Sandisk, PNY, Intense, Freecom, Transcend</ i>, Adata, G-Drive, G-Raid...
We carry out recovery processes on the damaged external hard drive and we will read the information that is stored with total seriousness and confidentiality.
Trust Laby, we can recover the information from your external drive.
Both internal and external mechanical disks offer capacity and performance at a relatively low cost. However, they contain fragile components such as reader units (heads) that can be damaged over time, through use, shock or unexpected vibrations.
To avoid further damage to the device:
* If the device is unrecoverable or the quotation is rejected, courier charges will be charged.
More than 29.800 devices in stock to provide a fast and economical service.
Own software and custom intranet.
EXTERNAL HARD DRIVE DATA RECOVERY PRICES
The price to recover data from external hard drives will always depend on the damage suffered by the device, together with the hours of work and technical equipment required to carry out the recovery processes.
In any case, a prior diagnosis is necessary to detect the type of failure or combination of various failures. Below we detail the most common breakdowns and the reference prices:
The prices for data recovery on mechanical hard disks are mainly determined by two factors: Damage to the mechanical hard disk components and the hours of work involved in the recovery.
At Laby we will NOT charge you a higher amount for data volume. Only because of the difficulty of access. This difficulty is also noticeable in today’s hard disks (SMR technology).
Older hard drives (around 2015) used the PMR or CMR format. The idea was simple, the reader unit was positioned in a certain area and read or wrote in a sector (a sector could be considered as a small box where information is stored). As an idea, we could say, that the width of the reading needle would be equivalent to the width of a track on these discs (A track would be the equivalent of a circle on the disc where inside that circle are all the little boxes or sectors). Inside a platter there are several tracks and these tracks in turn contain many sectors. The speed flow was constant and the module in charge of translating physical to logical information (Translator) was hardly corrupted. The modules or firmware, would be the equivalent of small independent programs, but that work together to make the mechanical hard disk work.
In order to achieve more capacity in the same space, manufacturers have developed SMR technology. The tracks are smaller than the reader unit and therefore fit more data density.
There is a problem, however, and that is that the reader unit or head cannot be positioned in a particular sector as it could with PMR or CMR technology. It must now read a set of sectors, load it into a buffer (swap memory), modify the necessary values and write the data again (both modified and unmodified data).
It is an inefficient process, which affects the disk performance in terms of writing and also entails major firmware problems due to all the operations that have to be carried out.
This example – although there are many more – gives an idea of why there is a wide “price range” for mechanical hard disk recovery processes.
If we don't recover your data, we don't get paid

Trust Laby, we can recover the information from your external hard drive.
HDD disks have as main components the metal plates (disks), where the data is stored, and the heads that are responsible for accessing the information. The most common hard disk.
SSDs do not move, hence the name solid state. The information is stored in blocks and no headers are required to access it. It is much more efficient and faster than an HDD hard disk.
External hard disks allow us to store outside the computer all the important information of which we want to make a backup copy. But one failure can cause us to lose all this data.
Apple devices, both iPhone, iPad, iMac, MacBook, Mac Mini, etc. They are reliable, elegant, powerful and easy-to-use devices.
On the laptop hard disk we store important work or home information. If a failure occurs, it can cause us to lose all this valuable personal data.
A SAN, NAS or DAS disk is a compact enclosure consisting of several hard disks that are connected via a network cable to the system, hence the common name network hard disk.
RAID disks are a redundant group of independent disks. They can be HDD disks or SSD disks and together they form a storage system to distribute or replicate data.
Pen drives or USB flash drives consist of one or more memory blocks. They work in many cases like SSD devices (same Flash technology).
Memory cards are used to store information from devices such as cameras, cell phones or tablets. They differ in their storage capacity and read/write speed.
We recover data encrypted with viruses or ransomware. Ransomware is extortion software: its purpose is to prevent you from using your device until you have paid a ransom. Depending on the type of ransomware, the entire operating system or just some files are encrypted.
In mobile devices or smartphones or tablets, the recovery processes can be carried out through the analysis of the electronics of the damaged components or, by carrying out the chip off process.
We offer the service of deletion and destruction of secure data with a certificate, either in our laboratory or remotely.
Computer forensic analysis and expert evidence. We recover and certify critical information with legal value for companies and individuals. We have collegiate computer experts to carry out certifications, expert analyzes and reports with legal value.
