As I've always said, hard drives are like courier companies, everyone has a horror story about at least 1 of them. It's usually a different one.
City Link is presumably the IBM Deskstar.
The Deskstar failiures apparently did so much damage to IBM that they sold their entire drive making business off. Prior to that they had a fantastic reputation.
Wiki says the following:
"Deskstar failures
The IBM Deskstar 75GXP, and several other models made around the same time, became infamous for their reportedly high failure rates. This led to the drives being colloquially referred to as "Deathstars".
Lawsuit
Despite failures being reported within the manufacturer warranty period (3 years), Michael T. Granito, Jr., an American user of IBM's 75GXP hard drive, filed a class-action lawsuit against IBM on 2001-10-16 for defects in the product causing it to "crash".[1] Without admitting responsibility, IBM settled this lawsuit in 2005.[2]
Details
A firmware update (details) gives a clue to some of the issues:
* Possible data corruption due to a problem with S.M.A.R.T. background operations.
* Application of wear levelling to avoid the heads dwelling too long over the same area
The drives were also known for commonly head crashing. The combination of two relatively new (at the time) technologies, GMR heads and glass platters may be largely to blame for the issues.
In addition to the failure that had led to the lawsuit, additional flaws were found in Deskstar 60GXP, 75GXP, 120GXP, 180GXP, which are caused by Giant Magneto Resistive read / write heads, and the easily corrupted NVRAM chip.[3]
Aftermath
Since the filing of lawsuit, IBM unveiled Deskstar 120GXP, Travelstar 60GH and 40GN in 2001-11-07.[1] The Deskstar documentation was updated to show the drives had been rated to 333 power-on hours per month (45 percent), leading to speculation that was the result of the lawsuit. However, IBM spokesperson replied that the rating is not new at the time.[2]
In June 2002, Hitachi and IBM reached a framework agreement under which Hitachi would purchase IBM's HDD operations. The deal was closed on 2002-03-31. On 2003-01-06, Hitachi announced the new hard disk drive storage company is named Hitachi Global Storage Technologies.[4] After finalising the sale of the storage division, IBM announced taking $2 billion charge in its second quarter.[5]"
