Hi there,

I'm just starting out with older Macs as a hobby and I have a Mac Color
Classic that has a SD card that acts as a hard drive replacement. The SD
card is formatted as HFS (not HFS+), as the Mac runs System 7.5 (HFS+ was
only introduced later).

My current-day Macs run macOS 10.13 High Sierra. I can read the HFS
partitions on the SD card just fine; but I can't write to them (I
understand Apple removed the ability to write to HFS partitions in Mac OS X
10.6).

Is there a solution to make the SD card writeable from 10.13?

- Maybe a 3rd-party driver that enables writing to HFS volumes? (Along the
lines of the Paragon drivers that enable writing to NTFS?)
- Maybe a 3rd-party app for transferring files?

I'd also be "happy" to use a Windows computer if there's an app for that. :)

Best,
Thomas

The easiest solution is probably an emulator. Several of the popular ones are able to read from the host filesystem and write to either a disk image or a physical disk, and this will also help with extracting old archive formats.

Use Mini vMac for an early Mac, Basilisk II for a later 68K Mac, or SheepShaver for a PowerMac.

welcome :-) i would like to know what kind of adapter it is? i know (and
use) scsi/cf- and scsi/sata-adapters, but don’t know sd card-based
models yet?

my personal workaround for a powerbook 3400: cf card (and of course
cardreader for the modern mac and a cf/pcmcia-adapter fort he old one)
with one hfs- and one hfs+-partitition. so i’m able to copy the files
later on the powerbook (if that makes any sense at all ;-)

> Is there a solution to make the SD card writeable from 10.13? 

this is not the answer to your question, but after all my favourite
solution is a dedicated mac running 10.4 or even better: 10.4 server. it
serves as a hub and connects smoothly to modern macs, vintage macs
(minimum: afp over tcp) and windows, too. a cube g4 or a mac mini g4 is
perfect for this job and does’nt cost much money and energy.
another, more esoteric solution: a virtual or real partition with haiku
(the beos successor). haiku can read and write hfs, too.

best regards
jan

I found Basilisk II fun to play with, and also it played well with OS X (however some time ago it was pre-intel).
My oldest macs run 8.1 - however for efficiency sake I've tried the loading up of system 7 with the backward compatible extensions that help with networking. My solution with vintage has been AppleTalk file sharing to a server with early OS X (as far back as Jaguar 10.2.8 still work with El Capitan - with me sitting at the newer machine). Note that vintage serial ports network very slow - scsi Ethernet adapter can be found. I use SD cards a lot for newer vintage such as my PowerBook 1400 ...
