please oh tecchnoid gods of the Amiganoid heaven
oh great ones give me a sighn
I can understand

only seem to happen when
i tried to instsll wb 3.5

have you installed the boing bag updates? what values have you got for the max transfer?
RDB errors sounds like a hard disk problem, but your'e using a CF card... hmmmm  :-?

[alexh]

Max transfer needs to be less than 128Kbytes or perhaps even less than 64Kbytes.

In HDToolbox change the MAX TRANSFER to 0x1FE00 or worst case 0xFE00

You'll undoubtedly have to start again and partition, format and install workbench all over. :-(

It could be that you have a duff card. It does happen.

Had similar problems and they subsided when I used a brand of cards approved for use by the good blokes at the english Amiga Board. They have a whole thread dedicated to CF card use. Good Stuf, saved me time and money.

My Black A1200 is all set and soon...CD32 with sx-1

My employer actually produces embedded hardware that boots from Compact Flash cards, and have extensively tested many, many cards. The difference in quality, reliability and read/write speed across brands (and even sometimes within a brand) is remarkable.

We have found Kingston cards to be the best for reliability and read speed. In fact we've not found any other brand match them for speed, but I don't think the CF card is the bottle neck when using it in an A1200, so that might be less of a concern ;-)

90% its an incompatible CF card....use SanDisk as they appear to be the best for Amigas..& also try the max transfer settings that Alex recommended..i would also check out a great thread on EAB on this topic

I've never known incompatible cards do this. They either work fully or they are not even detected.

i had a sandisk ultra3 card that was not detected. stuck it in a PC, created a partition, formatted, rebooted and to test, installed winXP on there. then stuck it in an A1200. worked fine. is there a switch in the firmware of the CF card to toggle removable/fixed?

[Crom00]

I had a CF card work fine on UAE on the pc, when transfered to the A1200 it was riddled with read/ write errors.

Stuck it in the PCMCIA adapter after a fat partition format on the PC and it still had slow reads and writes, and hung up the A1200.

So this it's hit and miss. Just happy I found a brand that works well.

I agree, same thing here.
Mostly I use Apacer & adata.

Oh Blessed Ones of The Amiganoidal Worlds
Thank you for your Devine Amigadvice
The EAB certainly helped with the pain I was experiencing in the CF regions all the sighns point to the brand of CF cards I was inserting I will in future only use the Sansdisk and other recommended by the EAB who seem to have visited the outer worlds of CFdom
I can say that Sansdisk works where ever you put it
and I was using three another brands  as Hard discs, pcmcia would continually pop as write protected,
thanks one again
