AuthorTopic: Amiga formatted CF on PCMCIA slot..... I've got the right numbers :-D  (Read 1126 times)

Hi,

I've almost got an Amiga formatted 64MB Compact Flash card to work as a removable device on the PCMCIA slot of an A1200 Desktop.

I'm finally getting an icon to click on and select 'Format' with FFS available instead of being hatched out. The problem is that with my current figures I am only getting an Amiga formatted capacity of 117K.

This screengrab shows what I now have :-)



An icon appeared on the Workbench screen after I changed the mountlist of the driver CF0 from:-


/* compactflash.device $VER: 1.21 (19.10.2002) */
/* fat95 file system by Torsten Jager */

FileSystem    = l:fat95
Device        = compactflash.device
Unit        = 0
Flags        = 0
LowCyl        = 0
HighCyl        = 0
Surfaces    = 1
BlocksPerTrack    = 1
BlockSize    = 512
Buffers        = 20
BufMemType    = 1
BootPri        = 0
Stacksize    = 4096
Priority    = 5
GlobVec        = -1
DosType        = 0x46415401


**TO THIS**



/* compactflash.device $VER: 1.21 (19.10.2002) */
/* fat95 file system by Torsten Jager */

FileSystem    = l:FastFileSystem
Device        = compactflash.device
Unit        = 0
Flags        = 0
LowCyl        = 2
HighCyl        = 235
Surfaces    = 1
BlocksPerTrack    = 1
BlockSize    = 512
Buffers        = 20
BufMemType    = 1
BootPri        = 0
Stacksize    = 4096
Priority    = 5
GlobVec        = -1
DosType        = 0x444F5303



(As you can see my changes which gave an icon on screen were to FileSystem, LowCyl, HighCyl and DosType)


Read Configuration in HDToolBox gives this additional information:-

Size: 62.6MB
Cylinders 236
Heads: 8
Blocks per track: 68
Blocks per Cylinder: 544
Total Number of blocks: 128384
Bytes per Block: 512
Park head where (Cylinder): 236


So can anyone tell me the right numbers and where to put them in the bottom mountlist for a capacity of 62.6MB please?


Thanks,

Simply use hdtoolbox to partitioning, save the settings and reboot, that's it!

62.6 Mb MEANS 64Mb, if counted by Amiga, nothing to worry about.
Goodbye people.

I\'ll pop on from time to time, RL is acting up.

:-) :-) :-)

Putting HighCyl = 128384 in the driver CF0 has given me an Amiga formatted capacity of exactly 62.6MB. After looking at the driver for an Amiga formatted 100MB Zip disk, I also added MaxTransfer = 0x001FE00 and Mask = 0xFFFFFFFE. Well I can read and write to it perfectly anyway :-D

@ rkauer
:-o I just came to paste that in and seriously wasn't expecting a reply. Many thanks for offering your help mate :pint: I couldn't get an icon on screen after using HDToolBox, but it was helpful in finding out the correct numbers to put into the mountlist of the driver CF0 :-)

I hope you are pleased with yourself as you got me bugged by this in the first place :laughing:


Note: To get screengrabs from the A1200 Desktop to this PC, i've had to keep swapping CF0 icon in Workbench:Devs/DOSDrivers and reformatting the Compact Flash card back to FAT. I know it's asking for trouble but who cares :lol:

Just one more thing........

Some of you may have used the High Density floppy drive in your A4000 to format a 1.44MB PC disk and get a 1.76MB Amiga disk?

Well this is basically all I have done here but on a larger scale as the PC can still read/write to the Amiga formatted Compact Flash card too.

I certainly wouldn't recommend that you write to the CF card with both the Amiga and the PC, as it will no doubt lead to corruption and the loss of all data eventually  :-)

I know I'm talking to myself but it's the only way I'm going to learn  :lol:

Although I got it working ok the numbers for the mountlist of CF0 were *not* spot on. But they are now:-


/* compactflash.device $VER: 1.21 (19.10.2002) */
/* fat95 file system by Torsten Jager */

FileSystem    = L:FastFileSystem
Device        = compactflash.device
Unit        = 0
Flags        = 0
LowCyl        = 2
HighCyl        = 235
Surfaces    = 8
BlocksPerTrack    = 68
BlockSize    = 512
Buffers        = 20
BufMemType    = 1
BootPri        = 0
Stacksize    = 4096
Priority    = 5
GlobVec        = -1
DosType        = 0x444F5303



:banana:  :banana:  :banana:  :banana:  :banana:


I'm outta here   :eek:

Why not just leave the card formatted FAT and use it in your Amiga and PC without re-formatting?
Time to move on.  Bye Amiga.org.  :(

Good question... I've been using the 64MB Compact Flash card FAT formatted to transfer stuff between my PC and A1200 for a long time now. I only started this task to try to help answer a question posted here:-

http://www.amiga.org/forums/showthread.php?t=23559

Personally I had no need for Amiga formatted CF cards but the Amiga challenge coudn't be ignored :-D

I'm now very interested in this and will be buying some larger capacity CF cards to play around with, and possibly looking into IDE cards as per the other CF threads around at the moment :-)
