I have a solid state drive I'm using for the OS + swap (mac os 10.6.8). Recently, I've seen an increasing rate of kernel panics. If I reboot and run Disk Utility, I can repair the drive, and I get messages about the number of directories being different. Of course, I can only repair when booting from an alternative source.

Is there any way to pre-emptively identify when bad sectors are going to arise and prevent the kernel panics, thereby squeezing a few extra months out of the dying drive? Or do I just need to replace the drive ASAP and pray I don't lose any more data in the meantime?

(FYI for those keeping stats: SSD was installed 11/2011, failures began 3/2013, was used as swap drive)

Is there any way to extend the life of the drive without wiping it? – keflavich Mar 24 '13 at 16:35
Personally, I haven't found any yet. – TFM Mar 24 '13 at 16:39

One method that has been recommended many times is the "Secure Erase" method.

The original question: Restoring performance and estimating life of a used SSD drive?
