ST9320421ASG Head Crash

John Wilson — Fri, 27 Jan 2012 14:59:46 +0000

This hard drive was out of a customers Macbook Pro. As you can see in the image, loss of data caused by a severe head crash. Another good reason why Mac users should make sure they back up regularly.

RAID 5 HP Smart Array E200i Recovered

HP Smart Array E200i SaS Drive

We have just competed a successful recovery from an HP Smart Array E200i RAID array. Not a standard case this. It had x3 DG146BB976 2.5″ SaS drives, two of which had been overwritten with a new RAID 1 mirror.

We found the disk order which was not the same as the labelled numbers. This is often the case. Also, due to the rebuild that had occurred we had to drop one of the disks and virtually rebuild it using the parity information from the other disks.

Seagate Head Crash

This Seagate ST31000333AS 1TB drive suffered a head crash resulting in severe media damage. The contamination caused by the damage can be seen on the disc surface as well as the internal filter. The filter is usually white but is now silver metallic in colour as a result of the contamination. The customer did not have any indication that this was going to happen.

Thai Floods Also Hitting Seagate

Dan Bennett — Mon, 17 Oct 2011 10:58:45 +0000

Last week we wrote about the Thai floods affecting hard drive manufacturer Western Digital. It now appears that the floods are causing problems for Seagate. Although not directly affecting their own manufacturing plants, the floods are causing problems in the supply chain, which could cause delays and shortages getting their drives to market.

Badly Damaged Heads

Inside a broken hard drive today we came across some of the most damaged read / write heads we have ever seen. Below is an example of how the heads should look. Notice how straight they are at the ends.

Then below are the damaged heads. They are at 90 degrees to the discs (tomb stoning) and would have been scraping the inner disc surfaces to pieces. Bad times!

We at Dataquest have been aware of the problem with 1TB Seagate drives for some time. It is pleasing to see that Apple are also recognising the problem and are offering their customers a free swap out. These drives are mainly seen in iMacs, but you may also get them in the Mac Pro so make sure your back ups are up to date.

More Seagate Momentus Drive Failures

Emma — Tue, 15 Feb 2011 13:46:56 +0000

We are still seeing these drives failing even after nearly 4 years. This just shows that there is no specific time stamp when these drives are going to fail. So anyone out there who still owns a original mac book with its original drive needs to make sure a regular back up is in place.

3TB Seagate Drive

Dan Bennett — Tue, 18 May 2010 13:48:01 +0000

A new 3TB drive is looming on the horizon, yet this may not be the breakthrough it seems. There appears to be major problems in the way older versions of Windows handle drives above 2.1TB. Windows XP and below will be unable to make use of these drives in any meaningful way, with some reports suggesting that only 990MB of usable capacity would be available to these vintage operating systems. It sounds like one more nail in XP’s coffin. If you need this mountain of storage it seems like it’s time to ditch XP already!

Seagate 7200 Snapped Spindle

John Wilson — Thu, 21 Jan 2010 11:08:18 +0000

We have received two of these failed drives recently in succession. Further clean room examination has confirmed that the spindle stack has detached itself from the motor base and coil. When first handling the drive it becomes quite obvious that this has happened as you can actually feel the pack rattling. Surprisingly we cannot see any physical damage on the media or contamination and fortunately the clamp has kept the pack secure. We would not recommend spinning the drive up in this condition. The only rework available is to transfer the pack into a good Seagate donor as part of the recovery process. Pack alignment is a critical part of this process.
