12/28/2018 0 Comments Raid 1 Drive As Boot Drive For MacRAID 1, also known as a mirrored set, would seem to be a perfect way to keep your critical data safe. The concept being that you have redundant drives. Whatever gets written to one drive will get written to the other drive. In other words, the drives are mirrored and look exactly the same. If I remove a drive from the RAID array, I can boot XP from either drive, either as a RAID-1 array, or by attaching to a SATA controller running in normal non-raid mode. At least, this seems to be possible (albeit with the performance issues mentioned in the OP). Heh heh, I understand using a raid 0 for the boot drive is a bad idea. I'm just curious why it is 'unsupported'. The term 'unsupported' implies to me that the software that doesn't support it won't run on it and I was curious why. For all intents and purposes, Xpress Pro shouldn't even know that a drive is striped. A RAID-1 array is 2 or more physical drives combined to create 1 logical drive. So Windows 'sees' only 1 drive, regardless of how many drives you used to create the RAID array. Accessing Disk Utility RELATED: To access the Disk Utility in macOS, just press Command+Space to open, type “Disk Utility” into the search box, and then press Enter. You can also click the Launchpad icon on your dock, click the Other folder, and then click Disk Utility. Or, open a Finder window, click Applications in the sidebar, double-click the Utilities folder, and then double-click Disk Utility. RELATED: To access the Disk Utility on a modern Mac—regardless of whether it even has an operating system installed—reboot or boot up the Mac and hold Command+R as it boots. It’ll, and you can click Disk Utility to open it up. In Recovery Mode, macOS runs a special sort of recovery environment. This allows you to use Disk Utility to wipe your entire drive—or repartition it. Partition Drives and Format Partitions Disk Utility shows internal drives and connected external drives (like USB drives), as well as special image files (DMG files) that you can mount and access as drives. ![]() On the left side of the window you’ll see all mounted volumes. RELATED: This annoyingly, but click Views > Show All Devices in the menu bar and you’ll see a tree of drives and their internal partitions. ![]() Each “parent” drive is a separate physical drive, while each little drive icon below it is a partition on that drive. To manage your partitions, click a parent drive and select the “Partition” heading. You can adjust the partitioning layout scheme here. You can also resize, delete, create, rename, and reformat partitions. Note: Many of these operations are destructive, so be sure you have backups first. RELATED: If you want to repartition your system drive, you’ll need to do this from within Recovery Mode, with one exception: APFS volumes., the default on solid state drives as of macOS High Sierra, and it’s got all sorts of clever tricks up its sleeve. One of them: volumes on the same drive pool storage space, meaning you’ll see two separate drives in Finder, but won’t have to manage how much storage space each volume uses. To add a new APFS volume, simply select your system drive, and then click Edit > Add APFS in the menu bar. Saving files in jpg or pdf. You’ll see the above prompt. First Aid Repairs File System Problems RELATED: If a hard drive is acting up, Disk Utility’s First Aid function is the first thing you should try. This feature checks the file system for errors and attempts to correct them, all without much intervention from you. Simply click the drive you want to check, then click the “First Aid” button. Be warned that these checks can take a while, and running them on your system drive will leave you with an unresponsive computer until it’s done. Secure-Erase a Partition or Drive The Erase button allows you to erase an entire hard disk or partition. You can also choose to only erase its free space.
