![]() So people seem driven to switch to APFS thinking it has some kinds of enhanced features. Why are you comparing APFS with ZFS? It seems that many people have fallen into the same trap. Or perhaps discourage the use of APFS on external drives which don't offer ECC protection out of the box, as my understanding is APFS can't do error correction as ZFS offers out of the box. Shouldn't APFS handle this case and be able to recover? Or perhaps consider an improvement to UX where OS would reboot instantly preventing data corruption. Second of all, Apple doesn't care about people playing around with APFS on external drives. Maybe someone from Apple APFS engineering team will read my plight use case above, try this simple use case of of disconnecting and reconnecting usb to other port and come up with a fix in disk utility.įirst of all, you were booted from an external device and then disconnected it. Now I'm at a dead end with attempts to fix partition.ĭon't waste your time. With your same Apple ID you can sign up for a free Developers Account and start a conversation with Apple engineersĭata corruption can't be successfully recovered ![]() Official channels to make your voice heard: How to choose between APFS and Mac OS Extended when formatting a disk for Mac - Apple Support I suspect you had a back up strategy in place. You where running your macOS off this external drive. Maybe someone from Apple APFS engineering team will read my plight use case above, try this simple use case of of disconnecting and reconnecting usb to other port and come up with a fix in disk utility. Now I'm at a dead end with attempts to fix partition. While I haven't had success with above tool - I did have success using disk drill to dig out buckets of files by file type but lost file/folder structure in process. I found this tool which can actually read partitions to recovery directory / files | -ĪPFS seems to be only suitable for internal Apple drives only which provide ECC protection.ĭata corruption can't be successfully recovered as Apple hasn't disclosed internals of apfs mechanics to other vendors / eg.

Last week the usb cord came disconnected - (at the time, I was troubleshooting other macs and wasn't paying close attention) I fatally plugged it back into usb port only on other side of mac causing drive to fail. I've been successfully using an external Samsung 1tb - EVO SSD via USB3 with macbook pro for over 6 months. ![]()
