scm PCD-50B question

Okay, this is starting to get REALLY WEIRD!!!!

Tried booting from the floppy with the CF boot card and SD card in place.  Floppy booted fine and the CF card was recognized and that was all.

Popped the CF card out and booted from floppy.  SD card is now recognized!

Perchance is there something wrong with the CF card???

Is it somehow locking out any LUN's after its position?

Guess I'll try a different CF card and once again install the OS.

 Basically, the same exact thing was happening to me and it turned out to be two bad, brand new, SanDisk CF cards! Are they SanDisk by chance? I was gonna ask Mike how his new Transcend card worked out. But from what I've been reading on the net lately, SanDisk has done something weird with their CF cards as of late. I shoulda bookmarked the reasons. I was tearing my hair out! Tried an old 2GB Transcend and all was great (with a dual boot double CF card setup).

i have used the new style sandisk ultras, with the different labels and they all worked fine( i tried about a dozen). Check your card serial #'s on sandisk site to make sure they are legit.(you can register for the lifetime warranty)-turn it in for a new one if its flakey. The transcend with the orange label(4gb) seem to work(i have about 6). and the 2gb transcends(blue&purple industrial) work always

 Thanks for the info Mech! I'll do that tonight! And yes, my old 2GB Transcend ALWAYS works!

Sorry to butt in with no constructive advice but, the two new bad CF cards are made by Kingston - with no front label and no verifiable part number searching the web.

Update.

After pulling the Hitachi 2GM Microdrive that I was using as my boot disk and replacing it with another identical unit, I was able to have it recognized by HDToolBox, partition it, format it, and install OS3.1 successfully.  My Sandisk SD 2.0GB is also recognized!

Conclusions:

It appears SOMETHING WEIRD is going on with my original Hitachi 2GB boot microdrive that precluded the system from recognizing the 2GB SD card!

I may try to recover the original microdrive at a later date, but for now, everything is working fine so onward to installing the 2386SX bridgeboard and getting that working with the SD card as the boot drive!

Details to follow, I'm sure!

 Glad you got it sorted! That's what it seemed to me too... something was faulty. Have fun with your Bridgeboard, I'm jealous!

I traded Mechy a genuine DEAD A3000T for one SCSI Reader... worth every penny he may have got for the Amiga. BTW, Mech... what ever happened to that A3000T? Did you ever get it running? If so, what the heck was wrong with that beast? I tried everything to get it to boot!

That's awesome you got 'er going! After dinking with it 6 or 8 hours, I knew I wouldn't be able to get it to boot without some spare parts. I'm just glad you kept it and didn't schlog it on eBay or elsewhere. Good to see Miggies get good homes!
