Data Recovery: Hard Disk Drives

Previous chapter: Data Recovery: RAID Disk ArraysNext chapter: Data Recovery: USB Flash, Memory Cards and other media

Data Recovery from Hard Disks, Hard Drives, HDD

Tip: Do you need urgent data recovery from hard disk drive (HDD)? Order our Express Data Recovery Service!

The most commonly used high-capacity media are hard disks, whether traditional, SSD or in RAID Disk Arrays. This media has gone through generations of development and continues to do so exponentially. To keep apace of the rapidly changing technology, we cooperate with hard-disk manufacturers in our continuous development of our own data-recovery services and technology. This, alongside our long history, enables us to recover data from obsolete hard disks to state-of-the-art ones.

Data recovery, data rescue: Harddisks

We recover data from all types of hard disk drives

We recognize and recover from disks of all interfaces:
ST-506 (MFM, RLL), ESDI
SCSI, FC (FC-AL), iSCSI 
Serial Attached SCSI (SAS), SSA 
ATA (IDE, EIDE, Parallel ATA)
Serial ATA (SATA, eSATA)
USB, IEEE-1394 (FireWire, i.Link)
PCMCIA, CardBus
CompactFlash
and some others
We support all generally used size formats:
5,25“
3,5“
2,5“
1,8“
1“ (e.g. IBM MicroDrive)
0,85“
We have rich experience in data recovery from hard disk drives of all brands:
Seagate – notebook, server and desktop HDD's;
Quantum drives, both IDE and SCSI;
Western Digital (WD) HDD's of all capacities and interfaces;
Hard disks by Maxtor (now Seagate);
Notebook HDD's by Toshiba;
Server, notebook and desktop harddisks made by Fujitsu;
Hitachi HDD's – SCSI, SATA, IDE as well as others;
IBM hard disk drives (now Hitachi);
Hewlett Packard (HP) brand, incl. OEM HDD's made by Seagate, Fujitsu, IBM etc.;
Ancient Conner harddisks (now Seagate);
Samsung hard drives – both external and internal, desktop and notebook;
ExcelStor drives (licensed IBM technology);
And many others.

Our specialty is Data Recovery from failed RAID Disk Arrays of all types, variants and configurations.

Hard disk drives damages

Thanks to the variety of technologies used, the large amounts of standardized types, and the various operating conditions, the list of problems that can afflict hard disks and that can cause data loss is almost indefinite.

Below we name only the basic types of damage, which we deal with most frequently:

Data recovery, data rescue: HarddisksElectronic
outer electronics (motor controller, broken data path)
inner electronics (pre-amplifier, motor)
re-written servodata / service area
Mechanical
scratched plates
broken heads
seized bearings
damaged servodata / service area
off-axis plates
We often see so-called software errors that can cause damage of modules in the service area and/or file system (partial re-writing or erasing).
Further description of software damages can be here: Data Recovery: Operating and file systems

How Data Recovery from a failed Hard Disk Drive works

In all of these cases we make bit-by-bit copies of data. In the majority of cases it is then possible to use the system after data recovery without having to re-install it!

Data recovery from a failed Hard Disk Disk Drive can be performed in the following modes:

EXPRESS - the fastest data recovery in urgent cases
STANDARD - during working hours
ECONOMY - if speed is not important for you and you rather prefer low cost

If none of the situations described above seems to describe your data loss please do not hesitate to contact us. We will gladly advise on the best next steps and as regards recommended solutions – because, the truth is, that:

"We recover what others can't!"
