Hard Disk Drive Data Recovery & Repair:
UniRecovery is very proud of its recovery record from IDE, SCSI and Apple Mac hard disks deemed “unrecoverable” by other recovery companies with humble knowledge & experience. Unrivalled success rate achieved is partly due to the importance it places on cutting edge technology of data recovery services.
A hard drive casing should never be opened up, unless in a cleanroom controlled environment. A single speck of dust entering a hard disk could cause fatal results. Hard disk fabrication requires a ‘Class 100’ Clean Room and UniRecovery undertakes all laptop hard drive data recoverey work in Clean Rooms ‘Class 100’ and ‘Class 10’. Commonly established, recovery from “Clicking” hard disk drives, can also be achieved under these specialised Clean Room conditions.
UniRecovery is capable of recovering data from the following cases of data loss due to Physical-Mechanical, firmware or Logical damage with problems such as:
- Formatted Drive.
- Drive not spinning.
- Inaccessable Data.
- Clicking drives
- Inaccessible Drive; "Drive Not REcognised by BIOS".
- Primary hard disk failure / Secondary hard disk failure.
- Inaccessible boot device.
- Unable to access drive "X"
- Disk error, press any key.
- Corrupt or Damaged Partition Table.
- Drive Not Booting Missing File/Directory Deleted File/Directory.
- Device not ready, reading drive "X"
- The drive no longer recognized by the BIOS after rebooting, despite the platters spinning.
- Operating system not found / missing operating system.
- The BIOS recognizes the drive but with garbage parameters.
- The BIOS recognises the drive but the data is inaccessible.
- Grinding or clacking noises, normally associated with electro-mechanical failure.
- The drive reports bad sectors.
- Corrupt data.
- Lost data.
- Formatted, Fdisked, partially re-loaded hard disk drives.
- NTLDR is missing, Press any key to restart
- Replace disk and press any key to continue
- Permanently deleted files, bypassing the recycle bin

External Hard Drives
External Hard Drives are Becoming More Popular
External hard drives are becoming very popular today as a means of backing up data replacing CD-RWs and even tape drives. Most of the major hard drive manufacturers are now offering external hard drives as part of their product line.
Some external hard drives contain a special chassis that not only protects the drive from vibration and shock, but allows the drive to be mounted vertically or stacked, one external hard drive over another. External hard drives are also engineered to dissipate heat. Some external hard drives are hot-pluggable, and feature both an IEEE 1394 "FireWire" interface as well as a USB 2.0 connector.
External Drives Great for System Back Ups
There are external hard drives designed to allow users to back up their data with the push of a button. Users can schedule backups and do basic restores of data. Some external hard drives have a backup button that lights up when first used, then fades out when the backup is completed. There are also external hard drives which back up all of the data on the drive when first used, then update the backup with new files or changes that are made to the stored data.
External Hard Disk Drives provide great flexible storage option and security by providing a mobile backup option.
With storage capacity running in hundreds of Gigabites, with high rates of data transfer, in addition to the flexibility to plug the external drive to a Laptop, Desktop, Server, Camera or ipod and sold at reasonable prices have increased their popularity dramatically.
However, as the popularity of the external drives containing backups and valuable data are increasingly failing for no apparent reasons. Majority of these failing drives are often of well known commercial brands such as Lacie, Freecom and Omega and with the latest high capacity Maxtor, Seagate or Western Digital hard disk drives models with storage capacity exceeding 320Gb or even 400Gb on a single drive.
The given hard disk drive Models are the cheapest, not fully tested with such hi capacity and worse brands available
Generally, inside the slick casings, often are poorly ventilated or even not ventilated at all, external hard drives assemblers include the cheapest available drives. If this set up is combined with badly ventilated casing, the combination is catastrophic for any given user, especially when the hard disk drive is of high capacity containing crucial back-up data.
For any given Lacie with multiple drives, this can be a terrible experience with RAID drives and data in excess of 1 terabite. Often with RAID array external drives, the drive failure are more frequent and the damage is more extensive than single drives. Many of the 1 terabyte LaCie external drives contain 250Gb Maxtor IDE in RAID array, inside casing, so badly ventilated, that if they are used regularly, especially within office environment, they are utterly disastrous.
Hitachi has unveiled a drive which has reached the new heights of one terabyte (TB). Its drive looks like any other, but uses perpendicular magnetic recording to make space for all that data.
The current technology generation of LRT-Longitudinal Recording Technology, which records the bits laying horizontally, has been superseded by the recording of the bits standing vertically.
