Help Using a Large SD Card

[yell0w_lantern]

I have found a number of tutorials for using a large hard drives and one tutorial for using a gb SD card in a real Amiga 1200. I have been unable to get either a 4gb or a 16 gb SD card to work using the tutorials. Both are Sandisk.
 
I can get them to show up in Win UAE but not on my A1200. In fact, it won't boot at all using the SD cards.

I used diskpart to clean the MBR off the card.
 
On WinUAE with Classic Workbench, I replaced the SCSI.device, renamed the SCSI device name to uaehf.device and enable Smart File Format. I made the first partition below 600mb then made the other partitions and set them all up for SFS and deleted FFS. Then I formatted using SFSformat. Finally, I copied the system files of Classic workbench over to the first partition of the card.
 
Do I need to snip a pin somewhere. I've seen that mentioned.
 
Also, I heard CF cards were pretty finnicky.

Did you set max transfer correctly on the sd?

If that is not the problem i would suspect the ide to sd adapter. They are not all created equal,wired correctly or even made well. If you are using a SDHC card your adapter must support SDHC also.

Its not so much a case of cf or sd being picky,some cards simply do not follow the standards correct. sandisk is usually a good bet to work if you didn't buy fake ones off ebay or somewhere.

Max Transfer rate 0x1fe00
