Re: Ext3 file system crash

[Eddy Jacob <hunt3r@gmail.com>]

Thank you very much for the help guys! :)

I've installed smartmontools, memtest86+.
First thing I tried was memtest86+, and it reported failure/errors. I
am using 2 memory chips, and luckily the fault only on the first chip,
so now I can still run linux safely with 512MB.

At the moment, I'm still running suggested dd to check for hard drive
IO fault. I think the hard disk is pretty safe.. at least until I see
the command finish without error in the log.

Thanks again, now I know what to use for checking memory in the
future. memtest86+ even allow me to make a bootable disk to check
memory. cool!
