Maybe.  The adapter card has a case jumper that could be removed and shorted with a wire connected between the lands on the pc card which would reduce the height a bit.  But you'd have to custom stamp your own back to make it thinner.  OTHO, if you started with an F40 and you'd end up with a thiner player, but to make it worth the candle you'd want to use the new 32gb cf cards.  (though if you started with an F40 with a dead hd you'd still be better off than when you started.)

I hope to play with mine more over the xmas break, and I'll chime in on IRC to discuss progress and ask sw questions of the developers.

Sorry about double posting but this thread was quite for a while and I have some new iinfo on adapters.

There are now at least three sellers on ebay with the CF to 1.8" hd adapters.
One of the sellers on ebay in the past has reported "working" on an adapter for the new 44in 1.8" drives.

In case other folks are considering this conversion, I would recommend sticking with the A-Data 40x for now. I've converted my iPod video. The A-Data worked fine without compiling a custom firmware and bootloader. The Transcend 133x pitches an error upon boot:

rockbox boot loader
version: 2.0
ipod version: 0xffffffff
ata: -80
no partition found

The iPod firmware works fine. I've also tried to compile a custom firmware and bootloader for the iPod, but no dice - same error.
Stick with the A-Data! It's for sale on newegg.com for about $80,-. If you wait a couple of months, you will probably get it for $60,-. Speed is no issue. The player is very responsive. Data transfers are slow to and from the player, but 'Hey' big deal.

Cheers.

I assume you are talking about this one:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820211170
and the price has dropped to $70!

also look at this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211244
the price on the 32gb card has dropped AGAIN and is now (only!) $180

I think when the price drops below $150 I will get very tempted to try it!


Also, as far as the transcend goes, you might try running fdisk and mkfs (if you are running linux) or disk manager if you are running windows and try to reformat the card before putting the ipod and rockbox software on the card and then see if the boot loader still fails.  But the problem may be in which of the ATA modes the boot loader is using vs which ones the card supports.  I bet the Transcend and the A-data are NOT fully supporting all of the official ATA modes.

help.me.spam.me@gmail.com:
Yes, that's the A-Data I am talking about.
I doubt my issue is related to formatting. The official manual recommends iTunes to restore the iPod, which should take care of it, but I've also tried to reformat it under Linux and Windows- no dice. I agree it's probably related to ATA modes.
Funny though both cards work with the original Apple firmware/bootloader without a hitch.
Bottom line ...

This CF did not work for me with Rockbox:

This one did:

Cheers

PS
Please check the topic "Rockbox and Compact Flash" in "Hardware".

It looks like setting the spindown time to 254 seconds has helped alot.
I still have a problem with "CRC error" in the rockbox boot loader from time to time
(recovers by itself on next attempt).

I do have a problem with getting stuck in the USB disk mode.  The only way to get the player out of USB disk mode is to toggle the battery switch.  If I hold the power button long enough the player does power down, but then won't power back up again, unless I toggle the battery switch.  Sometimes while it is stuck with the USB icon on the screen I see the status line, with the disk icon.  It doesn't matter that I have unmounted the player from the computer file system (under Linux using "umount /dev/sdc1" or "eject /dev/sdc1")

Maybe commenting out the reset function in ata.c causes this?  Any ideas?
