Disk Utility Stuck Checking File System

Everything worked as advertised, but due to file system overhead, you get a pinch over 90GB per disk, not 100GB, which is an unformatted number. They work with multiple-sessions, so you can keep adding to the disk.

And quite compact for a 4TB. Easy partitioning in Disk Utility to APFS. Highly recommended!

And quite compact for a 2TB. Easy partitioning in Disk Utility to APFS. Highly recommended!

Great product for setting WB and checking exposure. Folds up to about the diameter of a compact disk, so it fits almost anywhere

MacOS Disk Utility App formatted the LaCie 2TB Rugged for APFS without incident once I discovered that APFS was available only for GUID volume labels. About a minute of fiddling with Disk Utility Partition menu taking the defaults. Once formatted, the disk has proven fast and reliable as a photo storage medium. I expect 5+ years of solid service from it.

I use it for my Mac. I had to work at it to get FileVault to work with it on El Capitan - you need to reformat (no problem) and then partition, for which you need to go to the command line Disk Utility now. Not hard, just that Apple seems to want to dumb down the graphical Disk Utility. If you don't care about that, it works straight out of the box.

Works great with my Macs for video editing. Use Disk Utility to re-format drive for Apple, and it's plug-and-play. Bought to begin editing files on the road and finish at home. Scared by SanDisk reliability and wanted to get full use of Thunderbolt 4. Did not test speeds but it's very snappy. When expanded as in product photo, a small fan cools drive. Collapsing center turns it off and reduces size by a half-inch (to 4.0 inches) for travel.

Using the Mac Disk Utility, I was able to easily create both a Mac and a Windows partition to back-up raw footage and other video files. I always trust Western Digital and this product will probably not let me down either. It's sleek, quiet, and extremely fast with the USB 3.0. Would definitely recommend to anyone!

I bought this for my photo libraries when I bought a MacBook Air. The Mac Disk Utility formatted to FAT 32 with no problem. This device is affordable, transfers data fast, catalogs quickly, and is stable during access and photo editing. I can easily drag a RAW file to the desktop to speed the processing.

I had a support chat with OWC first before ordering this because of the cost involved. Wanted to be sure that I was sure that it would work with my 2019 Mac Pro. They assured me it would, so I ordered confidently. Installation was simper than simple, just lift the top, place the card in a slot, replace the top, boom. Booted, holding my breath, and it showed up in the disk utility. But showed only 8.64GB of available storage. I tried the Erase (initialize) option, Still 8.64GB. Then, went into the partition setup of the disk utility, and voila, there it showed the full 4TB (well, 3.84TB) storage. Once I claimed it all for a single large partition and then reinitialized the drive (using MacOS Extended, Journaled), all was well. I was then able to make full use of the drive. It seems funny to call it a drive, when it's actually just a thin chip on a PCIE-card. Even what you see in the picture there isn't really it. Most of that bulge is just heat sink. Amazing they can stuff that much storage onto something so small. Also a rather amazing amount to pay for a drive, but I wanted fast, non-internal storage, and lots of it, so felt the need and went for it. So far, it is behaving perfectly, is indeed fast. So after a few anxious 8GB moments, I'm relieved and happy.
