Re: uSD card content?


 

Josh,
?
You still? need a ap on your PC to read the CP/M directory in the container file.
so going direct is one step less.? If the one available works great.
?
Fat with the container file fragmented (scatter gather) would be bad and
CP/M itself? has the scatter-gather in the file system.? So you can have a
literal double scatter.? ?That is unlikely as the FAT file is built as whatever
size on formatted media, delete it and write again all bets are off.
?
>>>needs extra firmware to format / load blank SD cards
?
Not so, the card has base format (unlike spinning rust).? So an unformatted
drive only needs?a valid directory to use it and that easy to do?
C> del? d:*.*
It assumes the BIOS knows where D: starts on the media.
?
Oddly in normal operation CP/M does more reads than writes.? Most
common is directory.? Second most common file loading.?
?
Indeed it beats floppies hands down.? ?Ask me how i know... ;)??
Hint a very early adopter....
?
Still baffled why anyone would? small container files (like 360K)??
Might as well all be 8mb for elbow room not as if it takes much of the uSD.
?
Also what's missing is a way to remap any container file on the media?
to one of 4 drives.? CP/M allows that and I do that all the time on my
AmproLB+.? ?It allows me to use more of the larger disk without?
eating up the TPA for allocation tables.? ?Most of the systems
I've built are 4 logical drives (some 8 if the tables are in mapped
ram) with a mount utility to access other sections (containers)
on the larger disk on the fly.?
