Sorry, but you are wrong. Those SSDs depicted on photo have completely different pinout than CF, it's called 1.8 IDE. I had one of those on OQO 01+, and still own adapter that converts CF pinout so you can plug it to replace this kind of "CF connector" drive. Their connector is also slightly different so you can't just force CF card into 1.8 IDE (and 1.8 IDE drive is wider so you can't force it into CF)



Also, let me remind you all that CF standard has three types of operation, one of them is IDE emulation. There are cards that don't support IDE mode, CF readers/controllers also need to support this mode / talk ATA to card.

I see, thank you for the knowledge.

That explains why the previous one made by deanziyangyu didn't works. However the socket in the front is the same as Compact Flash
I tear down exactly the same board deanziyangyu posted, the black part in the front fits into the case of CF card perfectly in the picture I posted (the fly-wired one). That is the reason why I was thinking they are the same. And yes, you are right. CF and IDE 50 are two different stuffs.

PS: JM20330 is a two way chip set not only can do SATA to IDE but also IDE to SATA

Do you know that 99% all the cameras have a max limit of card storage that they accept.
Don't be worry about this, the SSD I used is a MLC one from cisco @ 64GB

PS: There are something in the end of the previous page.

No. CF card memory and device modes (except IDE mode) are just based and backward compatible to PCMCIA standard.

In the same way as IDE / UDMA modes are exposing IDE interface directly on CF connector and require direct passive adapter, in first two modes CF card is basically a smaller PCMCIA card.

CF host does not need to support PCMCIA. PCMCIA support CF as it acts like PCMCIA.

And "card readers" others than CF are either emulating PCMCIA memory mode, or are just straight PCI (PCMCIA) devices interacting with OS, thus requiring device mode support and drivers. You won't find this on camera.

Got you, thanks ;)

So exciting that this topic has been resurrected from the grave.

So if I understand correctly, any 'sata to IDE' converter that provides UDMA 7 and 150Mb/s read/write speeds while acting as a device not a host, should work with the right 'dumb' pin conversion adapter?

So what about an adapter like this:
https://www.amazon.com.au/Ableconn-IIDE-MSAT-2-5-Inch-Converter-Aluminum/dp/B017VQT5YW/ref=pd_lpo_23_t_2/358-1747184-0009040?_encoding=UTF8&pd_rd_i=B017VQT5YW&pd_rd_r=c92e0606-6922-40bf-8691-b3989882b6db&pd_rd_w=eTcEi&pd_rd_wg=wEvUL&pf_rd_p=ad2d1e6e-bc60-4795-b4c0-2dbd35f6678d&pf_rd_r=Z3ZX2WGHKTW3VHYPWNJ4&psc=1&refRID=Z3ZX2WGHKTW3VHYPWNJ4

Or even this:

If you're having trouble getting power into the drive simultaneous to it being initialised by the camera, you could use this adapter:
https://www.amazon.com.au/Bi-Directional-Adapter-JM20330-Chipset-Dongle/dp/B07M8S8MCM

And here's a ready to go fake CF card that takes Cfast cards
