AFAIK, all versions of MSDOS up to 6.22 supported only FAT12 and
FAT16.<br>
<br>
I'm using SanDisk, Pretec, and Canon cards. All seem to work OK.
The SDcard drivers for SBC-188, Mark IV, and Z80 boards all support
communication with SD, SDHC, and SDXC cards. SD cards use byte
addressing; SDHC and SDXC use sector addressing, but the drivers can
tell the difference between the card types.<br>
<br>
Rich, your write issue may be a faulty CardDetect or WriteProtect
switch problem, especially if you have the problem with only 1
socket.<br>
<br>
The SBC-188 and UNA drivers use CRC-16 checking on all data
transfers, and CRC-7 checking of all command sequences.<br>

<div>The HP tool enables you to specify FAT, FAT32 or NTFS and
they’re formatted FAT. I may try finding a 512mb SD card and

<div dir="ltr">Just a guess here but your SD cards are probably
formatted as FAT32. Does the version of DOS you are running
support it?
<div><br>
</div>
<div>Maybe try formatting them with FAT 16?</div>

<div dir="ltr">Hi Rich,
<div><br>
</div>
<div>Whilst I haven't used any SD cards on the
188 as yet, I have used them on the N8, Mark
4, PPISD and Multicomp. I mainly use SanDisk
cards and haven't had any trouble with them. </div>
<div><br>
</div>
<div>Note that there are two slightly different
SD cards available; SD and SDHC. There is a
small difference in the protocol needed to
talk to each one and the driver needs to
recognize the difference. </div>
<div><br>
</div>
<div>Cards up to 2GB generally use the SD Card
protocol and cards greater than 2GB use the
SDHC protocol. If you look closely at say an
8GB SD card you will notice a small SD HC logo
indicating that it uses the SDHC protocol.</div>
<div><br>
</div>
<div>I would say that you are safe using any
card size up to 2GB and depending on the
driver cards beyond 2GB.</div>
<div><br>
</div>
<div>Note that the Multicomp doesn't support
SDHC cards so you are limited to 2GB cards
there.</div>
<div><br>
</div>
<div>My own BIOS handles both protocols so I can
use any card. However, I only use a fraction
of the storage available (CP/M 2 is limited to
8 MB per disk) anyway.</div>
<div><br>
</div>
<div>Cheers!</div>
