DriveDx does the SMART things and is a lot cheaper than Techtool. Of course they do many things that Disk Utility doesn't do, so up to you whether they are worth it. Meanwhile, in my opinion, these apps are not worth having as they are unable to do the main thing I ever bought them for, ie directory repair and rebuild, which has to be done by fsck.
Whether Apple ever intends to release the APFS info is anyones guess. Disk Warrior just says it can't repair as I remember. My understanding is that Apple have still not released the necessary info for these apps to rebuild APFS directories, which they had done for HFS+.īecause of this TechTool and Drive Genius use the same fsck routine to verify and repair that Disk Utility First Aid uses. The issue is whether the tool supports the file system in the first place. Whether a disk utility tool can repair a particular file system has little to do with whether a Mac is Intel- or ARM-based.
I wonder about Apple Silicon and how will Alsoft and ProSoft Engineering respond to the new ARM based Macs? I thought formatting with Disk Utility would work but it didn't. I'm using the SD Memory Card Formatter now. SD Association – SD Memory Card Formatter They also recommend that if you are going to format SD-family cards on a computer, you should not use the standard Windows or Mac OS X formatting utility, but should, instead, use their special memory card formatter.
SD Association – Capacity (SD/SDHC/SDXC/SDUC) The SD Association defines FAT32 as the standard file system for a SDHC card, and exFAT as the standard filesystem for a SDXC one. Cameras don't understand any of those file systems. MicroSDXC cards don't have a lock switch.įor cards that you're going to use in a digital camera, you don't want to use APFS or HFS+ (or NTFS, for that matter). I didn't notice any lock from looking at the disk icon.
I've tried to format to the Apple File System (presuming APFS) from Disk Utility and it will either fail or be successful but nothing that I can see actually happens.
