Max transfer & mask for CF card?
I'm having a few problems with both a 128mb Sandisk CF card and a 2gb Kingston CF card installed in my Alfapower 500. I've been reading up on max transfer and mask values but have no idea what they should be for my setup?
At the moment i'm using HDInstTools and it shows these values (amongst others) for my 2gb Kingston CF card: Mask: 0x7FFFFFFC MaxTransfer: 0x0000FE00 Buffers: 2033 File System: FFS (version 36.104) DOSType: DOS/1 My setup is an A500+ with a KS 2.04 ROM (37.175), 2mb chip and an Alfapower 500 with 8mb fast ram (16 x ZIP chips) and 2gb Kingston CF card (via 44-pin IDE - CF card adapter). I'm quite sure the Alfapower IDE uses polled I/O and not DMA transfers if that makes a difference? And is RDB compatible. Any help is appreciated, cheers Last edited by PowerPie5000; 28 November 2010 at 01:16. |

I have no idea as this was automatically detected/set-up by HDInstTools. This kind of stuff goes beyond me as i've never had to deal with it before. HDD setup was plain and simple until i started using CF cards with an A500 sidecar expansion... Also i was just a gamer back in the Amiga days so i had no need to mess around with stuff like this!

Do you have any idea's as to what the buffer size should be for my 2gb CF card? I'm guessing by your comment that it's too large at the moment? (my A500+ has 2mb chip + 8mb fast RAM). Also do the mask & max transfer values look correct? Thanks |

What would you expect a doctor to do if you phone him saying "I am ill, please send me some medicine"? I would guess he answers "I cannot help you if you don't tell me what kind of illness you have". |

The problems include format errors..."format failed:error 21" using HDInstTools and checksum/bad sector errors when formating with WB2.04 and 2.1. I know the CF card is good as it's been thoroughly tested on my PC for any bad sectors etc. |

The values are ok. As mentioned above you were probably accessing beyond the 500 MB limit.

Well, i think i'm still going to try and find another GVP HD8+ as i find "real" fixed disks more reliable, although a bit noisy at times EDIT: I also have no idea how to use or even install that "Oktapus" update file you linked |

The OktaPussy.doc file contains installation instructions.
IDEfix97 might fix the issue, too. |
