Q: SMART DISK ERROR

I get an error message saying I have a SMART DISK error when trying to update the operating system and it states I need to replace the hard drive? Apparently the hard drive is working fine, so is there a way to trick the system on this code?

iMac, Mac OS X (10.7.4)

    If you have Smart Disk errors backup your system now, the drive will soon give problems.

     

    Arrange to have the drive replaced ASAP.

     

    The SMART system is designed to give you advanced warning of a drive failure.

    You can get a smart disk error if the drive is performing an excessive number of error corrections. That means you could be on the edge of being unable to correct the errors once too much of your redundant information is unable to be read.

     

    Also excessive error correction can slow down access to your disk.

    When a hard disk is broken you lost all of your data, your photos, your works, everything.

    Even your computer refuses to start, cause the OS is in your disk.

     

    It's a nightmare. To prevent this, hard disk came with a smart system that it's watching for early symptoms of fail, and raise the flag. That let you back up all your data, and change your disk.

     

    Before you install a new OS, the disk is checked, cause lot of things will be moved, so even the tiniest disk fault can raise a lot of system's crash.

     

    Your disk has the flag of about to die, even if you didn't notice anything...

     

    Don't look for hacks, speed up! maybe today its the last call.

    Hi Bob,

    I did not know how the SMART system worked but this is just like the SMD drives I used to work on 30 years ago, yes the ones the size of washing machines that held 300MB. each sector had an ECC and the controller checked and corrected errors using the ECC. Surprising how things use the same technology, only much smaller.

     

    regards

    An RP06 "REALLY" looked like a washing machine.  You slide the glass cover back and loaded the disk pack from the top, and with the disk out, it really looked like a top loading washing machine.

    These were CDC drives I worked on but the same size, fun days replacing and setting up heads after a head crash.

     

    Oh dear, going to get into trouble going off topic.
