The IPOD does not go into disk mode.
I have tried several times.
If you can't force the iPod into disk mode, then there's nothing you can do. That's not a matter of software, disk mode is built in on the hardware level. If you followed the instructions in my previous link, and it didn't work, then replace the unit.
As for Professional Help from an Apple Store Are you kidding me? Have you ever been in one. A bunch of vapid kids trying to look cool.
Kids who clearly know more than you do about Apple products. I've never, ever, seen an iPod that can't be forced into disk mode. I suspect you're not doing it properly, because if it boots up at all, then you can get it into disk mode. I can't see a failure mode where it'll go to the exclamation screen but be unable to force disk mode.
I think the fact is this Issue is common and Apple can not do anything about it.
The issue is actually incredibly uncommon. This sounds more like a case of PEBKAC.
I will advise everyone I know not to buy an IPOD cause of the trouble I have had and the simple fact, it doesn't work.
Advise all you like. None of it is true, but don't let that stop you.
And in the future, if you want actual advice, then please feel free to post here. But if you just want to complain, please go elsewhere. Apple doesn't read these forums, these are all full of people who use the iPod and try to help others on their own free time. I don't need you complaining to me, because I really don't care about you. I offered my advice because you asked a question. If you don't like that advice, well, you can shove it as far as I'm concerned.
