PCMCIA CF card size limit?
« on: December 11, 2008, 08:59:09 AM »
Hi,

I have a 4GB CF card which I'd like to use with my PCMCIA card reader on my A1200.

The reader works fine with the 8MB and 512MB CF cards I have, but when I put the 4GB card in, it doesn't appear on Workbench...

I suspect it's due to the fact the 4GB CF card appears to be formatted FAT32, rather than the FAT16 of the other two cards.

Is there any way to format the 4GB card so I can use it in the PCMCIA slot?

Cheers,

Mike.

Hi,

I have an XP machine... How do I format FAT16?

The only option in the format dialogue is FAT32...

When I format it in my digicam, it also goes to FAT32...

Cheers,

Mike.

You have to do it through the DOS console (XP sucks somehow) but don't ask me how, I am a Mac user.

yeah yeah, you mac users fly by the seat of your pants! imagine being able to use a computer without the rudimentery knowledge of at least 300 obscure command line variables! heresy i tells ya!

anyway

format /FS:FAT /Q

does a quick format with the FAT16 filesystem. :-)

-edit-

don't forget to put the drive letter on the end too  :-D

can't seem to get it to be recognised on my A1200.  Can you pmail me your devs/dosdrivers/cfd: file, the version of Fat95 and compactflash.device?

Hi,

I spoke too soon!

While I could format the CF card to FAT16 on my PC, it still wasn't seen when I inserted the card in the A1200 (via the PCMCIA adapter).

Even though the CF0: device was mounted, it wasn't visible to workbench and gave an error when I try to do a "dir" from the shell...

I've tried 512MB FAT16 and 8MB FAT12 formatted CF cards and they both work fine...

Must be something to do with the 4GB size...

Cheers,

Mike.

Both Compactflash.device and FAT95 support TD64 which basically means that cards can go well over 1 TB, so I doubt the 4GB size is the problem.

You can try to edit the CF0 mountfile and change this (got it from the compactflash.device doc):

Damaged or simply not quite officially standardized cards may sometimes
cooperate using

    Flags = 2    /* skip invalid PCMCIA signature */

BTW Some users have reported problems when using certain brands.
The new ones from Kingston for example (with the flowers on it) seem to be quite problematic for some users.

My is a cheapo/generic "Omni" 4GB CF card and I have exactly the same issue as stefcp2...

I'm also having problems trying to use the same card (via an CF-IDE adapter) as a HDD replacement - I can only see two partitions...

Cheers,

Mike.

I'm using a 2 GB Sandisk Ultra II CF in combination with a Transcend PCMCIA CF adapter.
Works like a charm !!!

Just to be sure, make sure that you've installed the following:

- Cardreset
- CardPatch
- Fat95
- compactflash.device
