UPDATE March 16 2012<\/strong> – there is finally<\/em> a solution to this problem – read the updates at the end of this article for details.<\/p>\n

Longtime readers will remember the computer drama<\/a> that unfolded back in May of 2008 when I bought my new 500 GB hard drive. Basically, when I tried to resize my NTFS partitions, GParted<\/a> (or, more specifically, the tool ntfsresize<\/a>) said “you’ve got bad sectors on your disk, I’m not touching anything<\/em>” and refused to run. I eventually lost the battle and settled for a (less than ideal) configuration for my new disk.<\/p>\n

Fast-forward to today – the public beta of Windows 7<\/a> is meant to come out today, and although there’s always the virtual machine route, for something like this I thought it might be worthwhile to dual-boot so it could have the full power of my machine (Vista under Virtual PC is OK, but sloooooow<\/em> – imagine what a beta <\/em>version of an even newer <\/em>OS would be like?).<\/p>\n

Since Microsoft’s web servers seem to be totally overwhelmed with the demand for Windows 7, they’ve taken the download off-line for the time being. So, given that it seems like I might have to wait a bit, I figured I might as well download the latest GParted LiveCD<\/a> (version 0.4.1-2 in case you’re curious) and make a little partition space available.<\/p>\n

As you might imagine from the title of this post, I wasn’t able to do it. It was the same problem as before – there were “bad” sectors on the disk, so ntfsresize refused to do anything. Oh, sure, I could <\/em>have tried to do it from the command line and used the --bad-sectors<\/code> option of ntfsresize, but I’m not one for specifying disk sizes based on cluster locations, which is how you’d have to do it. And I couldn’t even get the parameters that the GUI interface would have used when resizing, because it wouldn’t even let me try<\/em> to resize under the GUI to get the parameters!<\/p>\n

\"\"<\/a><\/p>\n

After all, what’s the point of a GUI LiveCD if you can’t use the GUI!<\/p>\n

What’s even more confusing\/infuriating is that every forum post or help document I could find on this subject seems to go like this:<\/p>\n

Novice User: <\/strong>I’m getting this “bad sector” warning – but I ran CHKDSK two times like it said, it found no bad sectors (or it found one and repaired it), but I still can’t run ntfsresize!<\/p>\n

Linux Guru: <\/strong>Your disk is failing, get a new one.<\/p>\n

Novice User:<\/strong> But…<\/p>\n

Linux Guru:<\/strong> YOUR DISK IS FAILING AND WILL DIE SOON GET A NEW ONE IT’S NOT A PROBLEM WITH NTFSRESIZE YOU JUST NEED A NEW HARD DRIVE DON’T QUESTION ME.<\/p><\/blockquote>\n

I have, of course, embellished this somewhat for dramatic effect, but you get the idea. The assumption is always that the problem is with the hardware. (Even the Wikipedia article on ntfsresize<\/a> seems to support this point of view, although in fairness it is<\/em> marked as [citation needed]!) I can understand a certain amount of healthy skepticism (in many cases bad sectors are a legitimate sign of a dying hard drive), but there seems to be a certain amount of… I don’t know, denial<\/em> – for lack of a better word – going on with respect to bad sectors that aren’t actually all that “bad.”<\/p>\n

If your hard drive develops a bad sector (as a result of a sudden power loss situation, for example – which is what caused my bad sectors), CHKDSK for Windows will find the problem, recover what data it can, and mark the sector as “bad” so it doesn’t get used again. Barring another power loss situation (fixed for me since I now have a UPS for my computer), the drive should be just fine for the rest of its natural life.<\/p>\n

Likewise with defects that were detected by the manufacturer (but not bad enough to reject the disk over) and marked as “bad” before they left the factory. I know<\/em> they used to do this with disks – I assume they still do.<\/p>\n

So, it certainly seems like there are situations (possibly quite common) where a drive will have “bad” sectors, but should still be safe to use and operate on. After all, the fact that they were marked “bad” means that they were detected and won’t be used again.<\/p>\n

Of course, I do<\/em> have to mention again that ntfsresize has a --bad-sectors<\/code> option which will ignore bad sectors… but there’s no way to access this option from the GParted GUI. You HAVE to do it from the command line – which kind of defeats the point. The whole wonderful thing about GParted in the first place is that it’s a graphical<\/em> way to resize your disk partitions. I’m a geek, but even I don’t like to have to specify partition sizes by sector\/cylinder offsets.<\/p>\n

So, if you were to ask me, I’d say that either:<\/p>\n
