Considering a change from Mac OS to Ubuntu to make darktable run better as that's >50% of my computer usage. I was minutes away from making the switch when I realized I have an external HD problem.

I have about 800GB of images stored on an external USB 3 hard drive. They're also backed up to a second USB hard drive (taken offsite) and a household NAS. Both USB drives are formatted APFS which is not readable by Linux. I'm trying to think of a free way to migrate those external drives to a filesystem readable by Linux or this is pointless. I could sync all 3 locations, install Linux, format one of the external USB drives, and then rsync it from the NAS but that's going to take FOREVER given the volume of data that I'm going to have to move over my network.

Without spending any money, does anyone have any good suggestions for possibly making it go faster? TIA

:biggrin: Let me google that for you! https://linuxnewbieguide.org/how-to-mount-macos-apfs-disk-volumes-in-linux/
But maybe that is nor your problem?
Migrating the drives is probably not possible, you have to reformat them to the new filesystem and that will mean that all data is lost!
So maybe the the best way is to get new disks and format them to something usable and then copy everything to the new disks.

Agreed. The best way would be to prepare new drives with Linux compatible partitions and copy all the files over. I think you can format the new drives into a format compatible with both Linux and Mac. Since you're going to be using these drives on a Mac, there should be an appropriate format. Sorry, I'm not expert enough to give that advice. The OP must not reformat the old drives before assuring that good copies are saved on Linux compatible drives. In fact, keep the old drives as backups until he's sure that the new drives are working perfectly. Even so, I would probably keep the old drives as an archive and have a computer that can access them if necessary.

I'm not sure, but I think the GUID Partition Map and FAT32 might be your best choices for the new drives.

Yeah. I was aware that APFS drivers are available but they are read-only, beta-level drivers and not recommended for use with any data you think is important.

There's also the commercial Paragon ext3 drivers for MacOS which would let me wipe one of the drives, format it ext3, and put the images back on it but that's $40.

One new drive would cost me $60 and I'd STILL have to copy all the images over the network.

I was a Linux/FreeBSD daily driver until Mac OS X came out in 2001. There's been a LOT of progress since those days. I was astounded how well Ubuntu ran on my old Mac and from a USB drive, no less!

You might be over thinking this. The images are in three places so for the short term I do not see any harm in restarting one. So first be sure the external drive you have and the NAS are properly synced (the 3rd offsite will be backup for this). Now simply reformat the external drive onsite to something Linux compatible then copy the NAS photos over to the newly formatted drive.
