9/28/2023 0 Comments Disk utility free space![]() The latest update to Disk Utility removes a lot of options from the GUI, but overall, I have yet to find a scenario where a task I need to perform isn’t still available, if only from the command line. To erase a volume called /Volumes/Seldon, use the same structure of the command, but this time without the freespace option: You can also secureErase a volume itself. Error: -69531: There is not enough free space in the APFS Container for this operation due to APFS limits or APFS tidemarks (perhaps caused by APFS Snapshot usage by Time Machine). For example:ĭiskutil secureErase freespace 0 /Volumes/Seldon > /var/log/secureeraselog.tmp If you were to automate the command then you would want to dump the output into a log file. In this example you would use the following:ĭiskutil secureErase freespace 0 /Volumes/Seldon So for example, let’s say you had a volume called Seldon and you wanted to do a standard Single-pass zero-fill erase. Here are the primary functions of Disk Utility on Mac: Repair hard drives using Disk Utility First Aid. For example, to perform a secure erase with 35 passes on free space on a drive named Macintosh HD you could use the following command string: diskutil secureErase freespace 3 '/Volumes/Macintosh HD'. The levels are as follows (per the man page as not all of these are specified in Disk Utility): Disk Utility on Mac is a free built-in tool that you can employ to finish all types of tasks. Run the following command, replacing X with the drive letter of the drive you want to wipe free space for: cipher /w:X:\ For example, if you want to wipe free space on your D: drive, you'd run the following: cipher /w:D:\ The command will show its progress at the command line. If the drive in question has a space in the name, you should place it in quotes or escape it with backslashes. The format of the command to secureErase freespace is:ĭiskutil secureErase freespace To do so, use the diskutil command along with the secureErase option. But you can still securely erase whatever you’d like (other than you boot volume obviously), when needed. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. Additionally, there’s no option to Secure Erase free space on a volume. Create a disk image from a disk or connected device. In a DOS box, entering smartctl -a sda (or sdb, sdc, or the like) will tell you everything you need to know about your hard drive’s SMART status–if you can read the sometimes overlapping information.One of the options thats a tad bit hidden in OS X is the Secure Erase option, which runs a multi-pass erase on a volume. ![]() If you love the command line, SMART Monitoring Tools might be for you. Several capable utilities allow you to view the information. Unfortunately, although many BIOSs will relay the basic “Hey, I’m okay (or not)” information to you when you boot the PC, Windows 7 doesn’t provide a way to access the details. Today’s hard drives have a self-analysis feature that keeps tabs on the drive’s health. SMART (Self-Monitoring Analysis and Reporting Technology) My other favorite freebie is Easeus Partition Manager Home: It’s professional in appearance and has all the features I generally need. ![]() Offering an extremely small footprint and very quick boots, Partition Logic seems to work fine, at least with internal IDE drives. According to the other post, there are two possible compatible free tools available. However, not all are compatible with macOS. There are third party tools that can move Windows partitions. Choose Utilities Choose Disk Utility Choose the LaCie External drive Click the First AID icon at the. WinDirStat is a disk usage statistics viewer and cleanup tool for various versions of Microsoft Windows. You need to visit the command prompt twice during the boot process, but I have on occasion found that GParted Live boots when the Parted Magic disc will not–and vice versa. To add the remaining free space back to the partition containing macOS, the partition containing Windows would have to be first moved to the end of the drive. With nothing selected, choose Go from the Apple menu. If you don’t need memory testing, or if you just want an alternative Linux partitioning boot disc, GParted Live is a slightly lighter-weight boot disc that also supports booting from a USB flash drive or an external hard drive.
