Don't trash an iPod with bad blocks on the drive
Authored by: tempel on Jan 24, '11 08:17:13AM

Not every bad block means that the entire disk will deteriorate soon.

I've had fixed installed disks where bad blocks were limited to a small area, and I kept using those disks (one for years) by simply allocating the bad blocks with a file, and making sure I never delete that file.

In other cases, especially if a drop of the disk led to the damage (which is especially likely with an iPod, though), the head might have gotten damaged, a moving part come loose or bent, and that's more likely to lead to more errors soon.

In any case - what this hint does is to try to repartition the disk, creating a unused space around the bad area. The description looks a little clueless, as it doesn't even take into account that the bad area could be anywhere.

However, if you have a little bit of a clue about how a hard disk is layed out, you can use my "iBored" to scan the entire disk for bad blocks. Then you can use those bad block numbers to decide how to partition your disk to avoid the bad areas. Or, even mark the area as bad, especially if you use the FAT format instead of HFS (in FAT, it's much easier to mark blocks as bad).

I could even add such an option to iBored, if someone would promise all my dreams would come true in return (or, pay me for it) :)

Don't trash an iPod with bad blocks on the drive

true, while not all indications of bad blocks will mean it will get worse, it does fairly often. And how much do you trust a drive that has already shown signs of a problem?

I guess with an iPod it isn't as much of an issue, since the computer is the backup for the iPod.

With a computer, I replace the drive every time, if they want to use the (possibly) failing drive as a backup or something like that, but not as a primary storage device.

Yeah, but what's your point? The article was specifically about making the best out of a bad situation - and for that's it valid, especially because an iPod usually only hold a backup of your iTunes lib, not original data - so if that iPod should die eventually, nothing is lost.
No one suggests doing that with your main hard drive, neither me nor the one who posted the article.
