Lexicon of data rescue

As soon as loss of data occurs, the first thing you have to do is shut down the data media that is at stake (e.g. hard disk) In this lexicon Attingo informs you about the professional terms regarded with loss of data, data reconstruction and computer forensics. The lexicon is continually worked on.

Term

 Explanation Other languages

autopark Combination of "automatic parking".
In shutting down electricity, the read-/writeheads of a hard disk are automatically being parked in a position defined in advance, in which any data is never saved. This will avoid damage to the hard disk when turning it on and off, respectively during transportation.

BIOS Abbreviation of Basic Input Output System
BIOS is the part holding software (firmware) which is connected to different types of hardware. This part contains the necessary driver software for computers, hard disks, add-in cards etc.

cleanroom DIN EN ISO 14644-1 describes a cleanroom as one in which the concentration of dust particles can be regulated, which has been constructed and is being used in a way that the amount of dust particles having access to it as well as the amount of dust produced in it, can be kept as minimal as possible and in which other parameters like temperature, humidity and air pressure can be regulated.
Cleanrooms are mostly being used in the manufacturing of semiconductors, in order to construct integrated circuits with the size of a fraction of a micrometer. Attingo GmbH makes use of cleanroom laboratories in order to secure your data while reconstructing them.

cluster A cluster contains a group of smaller data units (e. g: sectors). The amount of sectors belonging to a cluster, depends above all on the datamedia and the operating system. When a sector of a cluster has been faulted all data may nevertheless have been preserved and reconstructable.

data recovery Attingo is a specialist in data recovery and succeeds in over 90% of all cases. Technically data recovery means the regaining of access to data by the operating system, literally data-access-recovery.
The possibilities to recover data are as many as there are to loose them. Reasons for loss of data Attingo sorts as follows: software faults, data faults, RAID faults, hardware faults.

diagnose With respect to data recovery often analysis
Checking the damage, testing the possibility to repair the data in datamedia. The diagnose takes place before ordering the data recovery, in order to inform the customer about the real costs of the operation and on whether or not specific data can be recovered.

encryption Encryption makes data unaccessable unless one has knowledge of how to decrypt or decode them. Decryption is often bound to knowledge of a password. The advantage of encryption depends also on how difficult it is to access  the data without knowledge of this password.

FAT/FAT32 Abbreviation of File Allocation Table
FAT, respectively FAT32 enables the operating system to keep sight on the data stored on a data media. FAT32 is a more modern FAT-version, based on 32-bit. FAT is often being compared to the contents of a very complicated book but a better comparison is with the internet without a search machine. If the FAT has been destroyed, data may well be still there but the operating system has no access to them anymore.
Trivia: a hacker once said: "A datasystem with a faulted FAT is like a 10000 pieces Jigsaw named green as grass". The technicians at Attingo however will solve your puzzle and rescue your data.

HDD Abbreviation of Hard Disk Drive
Drive with hard disk, in which the disk is the data media. HardDisks are the opposite of FloppyDisks (i.e.: 5 1/4" or 3,5"-diskettes), which have a moveable data media.

head Write- /read head is a mechanical part which changes the magnetically stored data on a data media into electromagnetic pulses and vice versa. In a hard disk, rotation causes the head to fly on a layer of air. The flying height reaches nowadays 3 Nanometers. If a head touches the data media, the consequence will be a head-crash, and loss of data. The microparticles loosened by the crash will cause more collisions. Only immediate shut down of the hard disk will avoid more loss of data.

fr: 
nl: head
head crash Hardware damage to the hard disk. When the head in a hard disk hits the data media, one speaks of a head crash. While the damage remains minimal and is often not even noticed by the user, longer use will cause the infinite small particles loosened by the so-called initial head crash to collide with the data media. The longer the use, the more damage. Please contact Attingo to discuss what to do. You can call us free 24h at: 0800-80 81 86

interface An interface describes the communication between two components,if it is hard- or software. Also the communication with the user asks for an interface. A faultive interface may lead to continuous loss of data without the user noticing so. Data recovery asks here for the partial reproduction of the specific fault of the interface, in order to restore the data successfully.

parity Means the divisibility by two, respectively eveness.
The term is being used in relationship with data security and describes a simple and fast procedure to detect small, incidental faults in data transportation. When certain amount of bits are being transported, the paritybit shows whether the amount of transported ones was even or uneven. At this point a first, not completely reliable but plausible paritytest of transported data can be made. If for instance two bits have not been transported correctly, no parityfault will be announced.

RAID Abbreviation of Redundant Array of Independent Disks
A RAID-system serves to build several physical hard disks of a computer into a logical whole that allows more storage capacity, more data security in case individual hard disks fail and/or a higher data transfer speed than a single physical disk. While most techniques and applications in computers are designed to avoid redundances, redundant information is being deliberately developed in RAID-systems, in order to ensure that the RAID keeps on functioning as a whole, also in case one component might drop away.
The most used RAID-levels are:
  • RAID 0: Striping — acceleration without redundance
  • RAID 1: Mirroring — redundant mirroring of the data
  • RAID 5: performance and parity

RAID 0 Abbreviation of Redundant Array of Independent Disks
The number 0 (Raid 0) points at the level of RAID that has been realised. Zero is descriptive here, because there is no redundance of the data. In fact what takes place here is an acceleration. All partaking hard disks are simultaneously being loaded with data, which therefore can be written at a considerably higher speed.
In case a hard disk in a RAID 0 set up (RAID Level 0) is faulted, the resulting damage is to be compared to the breakdown of a very large hard disk.
The technical term for this procedure is striping (acceleration without redundance).

en: RAID 0

nl: RAID 0
RAID 1 Abbreviation of Redundant Array of Independent Disks
The number 1 (RAID 1) points at the level of RAID that has been realised. In case of RAID 1 all data are being played simultaneously on all partaking disks.
Faultive hardware in a RAID 1 part will not lead to loss of data, because all other partaking hard disks have exactly identical contents.
The technical term for this procedure is mirroring.
Unfortunately, an often held misassumption is that the high protection against technical faults makes data protection needless. However, in case data are being erased as a consequence of an operating error, faultive software or a virus, this will have an influence in all partaking hard disks.

RAID 5 Abbreviation of Redundant Array of Independent Disks
The number 5 (RAID 5) points at the level of RAID that has been realised. In a RAID 5 the advantages of other RAID levels are being combined so that performance and redundancy can be realised at low costs.
A faultive hard disk in a RAID 5 set can be easily replaced.

SCSI Abbreviation of Small Computer System Interface
A widely used standard interface in order to make parallel connections between computer components. Mostly used to put more than two hard disks in a computersystem. Other commonly used interfaces like ATA/ATAPI can address maximally two peripherals. Apart from operating several hard disks SCSI is also being used to connect scanners or optical drives etc.

striping The term is used in relationship with RAID 0 and describes how a RAID 0 is being arranged. Here data are as if it is segmented and disparately assigned to the partaking hard disks. The amount of stripes depends on the amount of hard disks.
