OSNews, Generic OSes No, your eyes aren't deceiving you - we have actually have not one, but two news items on hobby/small operating systems on the same day! You thought the day would never come again, but hey, here we are. You're welcome. Now, what are we talking about? FreeDOS - a test release has been, uh, released for FreeDOS 1.1.

Actually I'd say you are wrong, and here is why: All drives are designed to deal with a few bad sectors, that is why there is extra space on the drive you can't access. it is there to replace a failed sector or two.

Now what I have found is that for some reason on certain drives (cough cough Seagate cough) you seem to be more likely to get those few failed sectors towards the front of the drive and for some reason Windows simply refuses to mark them as bad. With Spinrite marking those sectors as bad the drive works fine, SMART checks out, all is green. In fact when my nephews HDD died I gave him one of those drives with a couple of bad sectors as a temp until I could get him another drive. That was two years ago and the drive is still running like a champ.

So we aren't talking about a drive with Gbs of space marked bad, we are talking a couple of Kb at most. I've found with SMART you'll get plenty of warning if the drive really starts to fail but with a few bad sectors they can go for years and years just humming along. As I said I use cheap USB enclosures with most of those that are of any decent size with that problem that comes into my shop and so far they are transferring files and running on relative's Nboxes just as sweet as sweet can be, YMMV of course.

the problem is that when the os sees bad sectors, the drive already ran out of backup-sectors
so the platters are either of low production-quality or got damaged later on
both are inacceptable for a new disk

and don't put too much trust into smart
i've seen several disks die with perfect smart-values

Actually I've found with certain drives (Seagate and Maxtor) if there are even a couple of bad sectors in the front? They will NOT be exchanged and Windows won't see them as bad. As I said I've been using several as USB drives for several years now, scanning them often, not a single error since Spinrite.

Of course I'd say Spinrite probably has a lot to do with that as if I am handed a bad sector drive I run a level 4 scan, which does 4 separate write/read and error tests before it calls it. If a sector fails even once? It is marked as bad. Sure it takes awhile to run that deep a scan but that is why I have an old 233MHz that was given to me that makes a perfect box for such tasks. Just sit it in the corner loaded with FreeDOS and Spinrite and let it do its thing.

But I've been doing this since Spinrite was at V3 and knock on plastic the only drives I've had die were head crashes which I got plenty of warning about. If it survives a spinrite pounding and comes out green? I'd have NO problem using that on a machine.
