Data Recovery Engineers tips
DiskEng is committed to bringing the latest news on its data recovery services and report findings that we believe will benefit our customers and visitors. Since prevention is better than cure, below are some helpful tips on avoiding the need for avoidable data loss and inconvenience.

1. Disk drives contain rotating media never shake or drop a drive as they are built from finely engineered mechanisms that are easily damaged by impact and can be irreversible.
2. Disk drives are meant to run warm not hot, ensure plenty of cooling even in winter.
3. Disk drives will not go on working forever, always keep a backup and never in the same location.....More

DiskEng is normally among the first to encounter data recovery requests, from new types of problems suffered by different models of drives released by the many different manufacturers. Although most disk drives perform well, below are the current findings of some of the most frequently failing drives. We are however proud of our data recovery success rates that has been on average in excess of 89% on these drives, thanks to new developments by our Research and Development Engineers.

February 2009 - Seagate firmware issue. 500GB - 1.5TB, this includes Barracuda 7200.11, Barracuda ES.2 SATA, and DiamondMax 22 drives, with firmware revisions DE12, HP12, SD15, SD16, SD17, SD18, SD35 and MX15. We have seen a significant rise in emergency data recovery requirements from many of these Seagate hard drives. The hard drive is not recognised in BIOS or the drive reports as 0LBA. Our data recovery engineers confirmed that the drives were failing due to a serious firmware bug, so the hard drives were not detected in BIOS. Our research and development engineers have investigated the Seagate firmware failure and can now successfully recover all of the data from these firmware affected drives. If you encounter a problem with your Seagate drive, safely power down the disk and contact us immediately for expert advice and professional data recovery...More

November 2008 - External Hard drives 100GB-1TB desktop drives, users that have dropped their external USB eSATA or Firewire drives should be aware that the drives on impact can cause serious read write head failure and more commonly motor seizure. Our data recovery engineers have recommended that once a drive has been dropped, do not power the drive. The most common symptoms are that the drive does not spin and makes a beeping or humming sound. This is usually because the internal motor has failed on impact. The drive will need to be rebuilt by our data recovery specialists before a full data recovery is possible. If you have dropped your hard drive either during power on or power off, contact DiskEng for disk recovery.

February 2008 - Seagate Moment us 60GB-80GB laptop drives, with firmware revisions 7.01 fail suddenly with the laptop disk clicking constantly. Our technical engineers have identified that this is caused by a possible firmware issue. The problem causes the read/write heads to fail at a specific point during use which leads to a complete crash of the disk platters rendering the disk data unrecoverable. It is recommended that the data is backed up and the drive upgraded. If however the problem becomes apparent, immediately stop the drive and do not re-power the laptop. Contact DiskEng for professional advice and emergency data recovery.

April 2007 - Western Digital WD Caviar 60GB-250GB desktop drives, fail suddenly with clicking, clunking and humming noises. Our research and development engineers have identified that this is caused by firmware damage and linked to excess temperature. Problem is apparent when the computer fails to restart operating system. Allowing the drive to click will damage the heads and crash the disk surface causing serious data loss. Immediately stop the drive and do not re-power. Contact DiskEng for professional advice and data recovery.

January 2007 - Toshiba MKGAS 30GB-80GB laptop drives, have been reported to emit clicking, grinding and whirring sounds. Our engineers have identified that this is due to poor spin tolerances. The noise is loud and is a clear warning that the drive has a problem. But users have caused additional electronic damage by constantly re-powering the drive, which is a far greater problem than the first. If the problem persists immediately stop the drive and contact DiskEng for advice and data recovery.

May 2006 - Toshiba MKGAX 20GB-60GB laptop drives, users may encounter sudden drive failure with no apparent warnings, typically the drive fails to spin, this is a common problem and is believed to be as a result of poor mechanical tolerances. Laptops experiencing symptoms such as sudden silence and no activities from the disk should be suspected. Although this can be damaging, it is important to contact DiskEng as soon as possible for advice and data recovery.

October 2005 - IBM IC25 series 20GB-40GB laptop drives, sudden increase in data recovery requirements. This has been mainly due to narrow working temperature ranges, customers may experience random failures, but its important not to attempt the mistakes made by many by power cycling the drive repeatedly, this encourages head failure at an alarming rate. Contact DiskEng as soon as possible for advice and data recovery.

February 2004 - Maxtor 6E040LO 20GB-40GB desktop drives, currently a major problem under certain extreme conditions, fault linked to excess temperature. Symptoms such as drive fails to be recognised in bios is typical. The results are damaging to the disk platters. The problem is not reversible without expertise in disk technology and DiskEng would normally recommend the drive is never operated outside of manufacturer ratings. If the problem becomes apparent avoid re-powering the drive, if problem persists after the first power cycle then contact DiskEng as soon as possible for advice and data recovery.
