Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Also, most disk manufacturers offer diagnostics for their drives; you might want to check that out as well. Good luck with it. As a general comment, if the bad sectors are numerous, it's probably a good idea to just replace it. Like a favorite pair of Levis, you might try to patch things up once or twice, but at some point, you just need to face the fact that you need a new pair of pants
ok, i dont know if its a maxtor drive but i can open the case and look. no problem.
is there a command line tool that will let me do a zero write ? the hard drive is only a year and a half old. will a zero write fix bad sectors ?
thanks, by the way.
not like replacing it would be too much, but 40 bucks is 40 bucks, right ?
probably a good idea, but not cost effective for me right now. i have all the data backed up. (thankfully) and right now its even operating, even though there is a 500 meg partition that i set up that i am not using right now. no big deal, but if i can fix it, i would like to.
the tools provided by manufacturers for performing low level formats are free.
When you do a low level format, you are completely re-writing the low level of the drive. This is replacing the level written by the factory, which is why it must be the tool from the manufacturer.
On the top of the hard drive, it will say the make/model of the drive.
Linuxquestions has a tutorial on zero writing Here. It is probably worth doing a zero write before a low level format (the latter takes a seriously long time - 40GB would probably take overnight and half a day). Zero write writes every single bit on the hard drive to a 0, so there would be absolutely nothing on the drive.
ok another quick question.
whatever is wrong with the hard drive stays wrong with it after i reformat with ext3.
i tried this with the ubuntu install disk to just have it reformat and install and it failed.
but after i created the "bad partition" and used a different part of the drive to mount as / ,
is a bad block or bad sector a physical problem on the drive or is it something that the zero might can fix ?
a zero write will return all bits on the drive to 0 - a normal format would just overwrite them. As it doesnt effect all bits, it most probably wont write over the bad sector.
Where that tutorial doesnt recommend low level format (which is true) its not caused problems here. Done it twice to one disc, before i heard of zero write. If there is a bad sector, and nothing else will fix it, then it wouldnt be much to lose to try it.
