interpreting smartmontools output
Hi,
I read about smartmontools on "debian package a day", and tried it out.
Running "smartctl -A /dev/sda" on my recent laptop (bought it this
spring) gave me 8 times pre-fail and 15 times old_age.
On a two-year old machine, that would worry me, but my instincts are now
instead to mistrust smartmontools. Is this a reasonable approach?
I had severe problems with lost file systems just after I bought the
computer, but after setting the kernel to use soft iommu, that problem
went away. Apart from that I never noticed anything strange with the disk.
(I use Lenny amd64)
Has anyone else experienced similar results?
Thanks
/ johan
