Back box by Gramps saves the SSD image

On July 31, 2013, in news, by

So as my backup box by gramps nicely restored it, it wasn’t a major disaster but I just had a laptop with a Samsun SSD 830 Model MX-7PC128 crater and die.

It basically froze up on us as Cliff was doing a presentation last week on Azure.  I unplugged it, plugged it back in, it booted but it would freeze and die ever since.

Just a reminder that when SSDs die, they die without warning.  To make sure you have a backup of them.

    Nice to know about blackbox by gramps, it is indeed a god send.

    anyone have suggestions on how to best monitor SSDs for impending failure? we recently invested in a lot for a virtualisation project – the warning we have been given is that disks from the same manufacturer batch tend to die at the same time. Happy days ahead

    You can’t “monitor” a drive for impending failure. A drive can fail at any time. ALWAYS have a backup. Don’t rely on SMART data to tell you that a drive fails because it’s proven to be unreliable. For high availability, use RAID. RAID is no replacement for a backup though.

    If you want to test a drive for reliability, use SpinRite on it from time to time to test and refresh every sector before data is lost. If SpinRite finds a problem, then it’s already serious.

    My rule of thumb is this: if a hard drive even has 1 identifiably bad sector, it’s time to replace the drive. When your disk checking software detects one, it may already be too late to save the data that’s stored there, so this is why you have a backup. Test your backup drives too.

    Let’s look at an example: people often think that the Shrodingers Cat only has 2 states: 1 state where the cat (your data) inside the box (your hard drive) is dead, and 1 state where the cat is alive. However, the cat can be DYING (“partially” dead), or you can take a metaphysical stance on the problem and say that if you can’t see the cat, how do you know the cat is even in the box (i.e. do you test a read-back on your data when you write it)? This is the way a hard drive works.

    ..of course, the cat could suffocate before it dies of the radiation poisoning too….that’s always an option.
