Since 2006 when I got my first D1 I have had two CF cards go bad on me, for no apparent reason. In terms of electronic devices I don't call that bad. Along with mechanical things, electronic devices can suffer failure, solid state drives and hard drives are said of fail in a similar percentage, a CF card is a form of solid state drive.

My personal experience of 'industrial' CF cards is limited. Recently I had my heart monitored with a recording device for 24 Hrs, that device was fitted with a non photography CF Card. Don't know what capacity.

When I worked for a chain of betting shops, the gaming machines contained at least one CF card which was used for the programming of the games, they were changed from time to time per machine, from memory, some had more than one CF card. Again not remembering the capacity they were not labeled like our photography cards, although I was told they could be formatted to contain photography/camera images.

I have just run all my smaller CF cards through my D1x.

One Viking Interworks 256Mb CF which worked without formatting and after formatting in the D1x.

One SanDisk 512Mb CF which worked without formatting and after formatting the D1x.

Three (I have a fourth somewhere) Kingston 1Gb CF which all worked without formatting and after formatting in the D1x.

Two SanDisk Extreme IV 2Gb CF which both worked without formatting and after formatting the D1x.

Then something of an oddity, the SanDisk Extreme III 4Gb CF which worked as inserted but after formatting in the D1x no longer recognised. I tried formatting it with the 'two button' method and from the menu. More research needed...

One SanDisk Ultra II 4Gb CF which as not recognised before formatting or after formatting the D1x.

Finally, One Kingston 4Gb CF which as not recognised before formatting or after formatting the D1x. I think this card came from JK with the D3.

Just for completeness and a bit of fun, I tried a SanDisk Extreme 120Mb/s 32Gb CF from my D3 but not unexpectedly it didn't work, with or without formatting.

I still need to resolve how the SanDisk Extreme III 4Gb CF worked initially but not after formatting. I will try formatting it in the Mac, not sure if I can format pre. fat-32 in the Mac, I don't have a PC set up and working so I may be stumped on that.

Update:

I reformatted the SanDisk Extreme III 4Gb CF in my MacPro, tried various options but nothing worked, probably needs formatting from command line, in an old PC which can talk DOS. I am pretty sure it's still formatting as a 4Gb drive in the computer, it needs a smaller (2Gb) partition which I can't do with the Mac. :banghead:
