Hi! some ideas:

Does the card show up on Windows' device manager? Have you tried moving the card to something like primary slave (if your adapter has jumpers for that)? Have you tried replacing the secondary IDE cable? are you using 40-conductor or 80-conductor cables? some CF-adapters seem to be better thn others, would you mind posting a pic of your card+adapter? if you boot into plain DOS, does fdisk see your card?

sounds like a display bug. should run fdisk and see it fdisk sees it all. If fdisk shows that its 29-31 whatever in there somewhere size partition than its a display bug in windows and you need a patch. Which there is a patch. But if fdisk doesn't report it correctly than likely the partition is messed up and that is why. Scenario 3 is your bios doesn't support hdd of that size, so even though its 32 gig formatted your bios doesn't see it all and is reporting to windows its smaller. Fdisk should be able to diagnose that. I guess scenario 4 would be the partition table or boot sector is messed up so even though its formated 32gig it is reporting to the bios its smaller.

You should also flash your motherboard to latest bios.

How did you format the SD card? DOS and Win9x sometimes don't recognize the partition on CF/SD if you have formatted the card on a modern machine, even if you choose FAT/FAT32 when formatting.

Go to DOS mode and use fdisk to check if the partition on the SD card is recognized as "non-DOS." If so, delete the partition and reestablish one with fdisk.

Thanks for the advice, I didn't try device manager, will try that today. I did try fdisk, but it fails to see it at all. The card was formatted FAT 32.

The card is a startech IDE to CF, set to master. https://www.amazon.ca/dp/B0026OYEEQ/ref=cm_sw … ding=UTF8&psc=1

One more thing, although it is detected during the boot sequence, when it's plugged in the boot is much, much slower then if it is unplugged. It's not the primary boot drive.

Hey folks, was able to fix, I had to use rufas to reformat the drive in FAT32, apparently the default FAT32 had some issues. Thanks for the help!
