![]() So you must set whichever is the next setting. Note that the indicator is normally set to 0 passes. Use the indicator to select the number of passes. From the dropdown panel click on the Security Options button. If you use Disk Utility, then select the disk entry (Apple SSD SM0128G) and click on the Erase button in the toolbar. ![]() There should be some indicator of success. This particular solution will affect that life but I don't think the life of the SSD is shortened dramatically. Unfortunately, doing this on an SSD will affect the life of the SSD which is affected by how many write operations the SSD can perform before failing. It involves a one-pass secure erase that writes zeroes to the entire disk. I know of one possible method to fix an SSD. The article seems to be for fixing an external drive. Here's another article on fixing this problem: How to fix deep formatting problems with OS X drives | MacIssues. Parted Magic also contains other utilities which can access the SSD's SMART features to check its health and even run the SSD's internal self diagnostics (again not all Apple SSDs have these features). Normally the "ATA Secure Erase" will take somewhere between 30 seconds to several minutes (maybe even up to five minutes for some SSDs). If you forget this password the drive may become permanently locked if the procedure does not complete successfully. Keep it simple with something like "abc" since you may need this password to unlock the drive if the erase fails or is interupted. The "ATA Secure Erase" option will require you to sleep & wake the computer followed by supplying a temporary password to enable the security feature necessary for the ATA Secure Erase. All other options will just cause undue wear on the SSD by writing zeroes to the drive. Within the app you will need to select the "ATA Secure Erase" option as it is the only option that will reset the SSD to factory defaults. There should be an icon on the Parted Magic desktop for erasing drives. Option Boot the USB drive and select the orange icon labeled "EFI". If the computer is using an NVMe SSD, then the paid version is most likely necessary.Ĭreate a bootable Parted Magic USB drive using Etcher (Mac/Windows/Linux). While the interface is a bit different, the basics are the same. Here is information about the procedure using the newer paid version. The last free version of Parted Magic can be downloaded from the Major Geeks' link here. ![]() Parted Magic is a customized Linux utility boot disk which has this ability to reset an SSD to factory defaults with an easy to use app. However, not all Apple SSDs support this feature and it does require the use of a Linux utility. It resets all blocks on the SSD with minimal wear and it also resets other aspects of the SSD to factory defaults which can also fix some weird SSD issues. ![]() SSD info and health bars are portrayed below and based on the info can i use this with ease despite being used for around 1.A better alternative to writing zeroes to an SSD is to reset the SSD to factory defaults using SSD's built-in hardware secure erase feature. And yes according to hdd sentinal trim is enabled And i got an option of secure erase in the transcend ssd scope utility but unfortunately it is greyed out and cant be utilized, so in this situation which way of formatting will be more preferable as i will use the drive personally. Thanks for replying, actually i will be cloning the system drive of my laptop mechanical disk into the ssd by connecting the ssd into the laptop during cloning procedure . How were you going to do the install? That could have an option for a routine wipe/overwrite. Personally I wouldn't go out of the way just to run SE before reuse. ![]() It shouldn't be needed if the drive has been used with TRIM enabled, which it should be in recent OSes. You can still do it, with a possible benefit that the drive will be fully reset and should be at highest possible performance. That's more for security if you wanted to help ensure possibly sensitive data doesn't get out if reusing the drive outside your control. If you're moving a drive from one system to another, both of which are yours, you don't need secure erase. ![]()
