16GB CF ...yet another not compatible

I'm willing to try if anyone has it. My data's already backed up.

I realized its pointless to format from the jornada since it can't recognize the CF. But I did it anyways. found a demo of "StorageTools" and formated w/ 512b. The system starts to act painfully slow after accessing CF for the first time after a soft reset. Then formated w/ 8k and its back to normal speed. (default was 16k).

I have a lexar jumpshot (usb) for PC, but it can't even detect that this CF was inserted. and my old (OLD-OLD) digi cam, same thing. I know I can't use sdhc on sd, but this is CF.

I've GOT IT WORKING!!!

I used ExDrive.dll from Storage Brick Driver by Tapani J. Otala.

edited my registry: HKLM\Drivers\PCMCIA\ATADisk\Dll=ExDrive.dll and it worked.
Here's the readings of the drive:

--General Properties--
Used: 16,384 bytes (16.0KB)
Free: 16,127,31,872 bytes (15.0GB)

--Flash Format--

cluster size: 16kb
total clusters: 984,532
backup fat: yes

I'll be submitting an update to the HCL after some more test.
Even though it says 15GB, but it says 16GB free. Is that normal?

It is. FAT table is stored in that secret space.

The FAT table isn't 0.97GB for a 16GB device, I assure you.

It's the whole "What is a Gigabyte?" debate. Storage device manufacturers almost always list 1GB as 1,000,000,000 bytes, while Operating Systems usually calculate it as 2^30 bytes, or 1,073,741,824 bytes. Take 15.03GB times that number and you get 16,138,339,61? bytes. (Yes, the last digit is a question mark. Since my calculator only has 10 digits, I dunno what the last digit is.) So, the card is just over 16,000,000,000 bytes, and that makes it 16 Gigabytes as far as the card manufacturer is concerned.

Oh, and to get back on topic, congratulations to sa1110 on solving the problem. Yes, it would be very useful to have this kind of info in the HCL.

Thanks. I've updated the HCL and also done a full read test of this CF using "PC Card Format Tool". It read successfully at 2.96MB/sec and have since transfered over 2gb from PC w/ no problems. :thumbsup:

Actually, a CESD how-to page on this would be even better.

Thanx for bringing back the ol' "Fun With Numbers" discussion, btrimmer. A propos:

FAT table of my 8 GB FAT32 4 KB cluster CF is 0.43 GB.

FAT is an inefficient method of allocating disk space, but it's not *THAT* inefficient. However, we're getting off topic here. So, I'll simply leave you to read the following link...

I want to buy a 8gb or 16gb for the jornada, is there a sum up page saying type/model of CF-I are working with the jornada, and dll tips eventually.
A sum up somehow.?
I am intended to buy a scandisk or a kingston, in order to avoid any kind of disappointments once bought.

Go on then good sir, I'm not the only one around here who can type

Sure, but if I type it, it's hearsay, since I haven't done it myself. So I'll have to consult with the expert above who did it first.

Just tried the above mentioned method with a MaxFlash 16GB CF card and worked. Thanks sa1110!
