Apple has issued a recall notice for what is describes as 'a very small number' of the latest iMac.
The company says that 21.5-inch and 27-inch versions of the much-copied desktop machine sold between May 2011 and today, and which were factory-fitted with 1TB Seagate hard drives, could fail 'under certain conditions'.
Anyone who provided a valid email address when they registered the product should have been notified by now but, if you're one of those people who doesn't want thier details on Apple's database you'll need to work out if you have a broken machine on your own.

If it turns out you are, indeed, the proud owner of a shonky Seagate hard drive you'll have to back up your data and haul it back to your local Apple Store for a Genius to look over or to an authorised service provider.
Apple says it will replace the hard drives free of charge until July 23rd 2012 and will consider further extensions at that time.
Apple is remaining tight-lipped about the exact nature of the flaw but we'd suggest anyone with a recent iMac containing a 1TB drive should be even more vigilant about back-ups than normal, even if yours is not included in the recall.
It wouldn't be the first time it happened if that 'tiny number' of affected drives turned out to be substantially larger than either Seagate or Apple is willing to admit.
Seagate has been plagued with failure problems in the past with both desktop drives sold at retail and parts supplied to box builders becoming the subject of recalls.
In 2009 the company was forced to offer a free data recovery service for some of its Barracuda line of drives when a firmware bug moved large chunks of user data to a hidden directory making it look like it had been deleted.
