![]() ![]() ![]() I think the SSD manufacturer maybe has a tool to secure erase and test the ssd. I have been running Linux for over 20 years, since before I had Win95. NVMe SSDs take 1 hour per terabyte per pass. ![]() You can get Linux based "Parted Magic" to do the Secure Erase with minimal wear, but it now costs $4.99 instead of being free. Sanitize Cypto, Revert, and RevertSP (PSID) take at most 2 minutes. My old Intel 80 GB SSD either came with such a program on small CD or I downloaded it. There is an ATA Secure Erase command that can erase all blocks at once with minimal wear, but not sure how you can do that without a program. Trying to do something like write all zeros to the SSD may not do that and can also result in excessive wear leveling. TRIM in Win7 or newer can clear blocks automatically as you delete files or programs. And if the block is not erased, it has to erase the block before it can write to it, slowing it up some. You can clean free space or even wipe an entire drive (SSD or traditional), so long. 引用自 MaddDoktor Linux:SSD's internally work somewhat different than a mechnical hard drive in that they cannot randomly change individual bits, they do it a block at a time. Hardwipe is another data destruction program that runs from inside Windows. Yes, wiping the free space on SSD is a quick and hassle-free process if done by using the right tools in hand Now, if we talk about the process to wipe free space SSD, then there are two possible solutions that entirely depend upon whether the TRIM function is enabled or disabled. If I create a Ubuntu bootable USB stick and run Linux from it, is there an easy way to wipe SSDs within that OS without fully installing Linux on that PC? I'm not too tech-savvy on Linux operating systems, so help will be appreciated. I've seen where disk drives can be wiped using CCleaner, but I don't want to go through the trouble of reinstalling that drive into my newer PC since I already put the drive into the old PC. Older folks will be using that PC and I will not be the primary user of it. Before I install Windows 8.1 on it, I need to securely wipe the entire drive clean, removing all traces of my personal data from it. And no, I'm not upgrading it to Windows 10 because I tried upgrading from Windows 7 to Windows 10 and that PC did not like it. I need to install it on an older Windows 7 PC and put Windows 8.1 on it. Step 1: Firstly, download the Parted Magic and create a mountable USB flash drive using any reliable utility, i.e., Refus.I have an older Intel SSD which has an old Windows 8.1 / Windows 10 dual-boot setup which I'm not using on my main PC any longer (I installed Windows 10 on a newer SSD). Therefore, here we have explained how to secure erase SSD using Parted Magic in detail you just need to follow the below stated steps precisely. Does eraser really wipe free space on SSD drives pristine2 P pristine2 New Member 1 The FAQ on the ccCleaner sites claims that wiping free space on an solid state drive is useless, and will do nothing but reduce the life of the drive. Parted Magic is considered one the best application to erase SSDs & HDDs securely. ![]() Though the utilities offered by SSD makers to securely erase SSD are quite effective, but if your SSD doesn't have any built-in secure erase utility, then you can also go for a few other handy methods to securely erase SSDs. Therefore, it is always recommended to enable the SSD trim you can also manually enable it if it is disabled on your system by default. 01 of 35 DBAN (Dariks Boot and Nuke) What We Like Can erase the whole OS. Basically, the SSD Trim command is used by operating systems to inform the SSDs about the blocks that are no longer needed so that SSD can either delete such unrequired blocks or mark them as free to rewrite with new files. SSD trim is a command that proves to be quite effective in prolonging the SSD lifespan and improving its overall performance. If you have a solid-state drive or SSD, then you might be familiar with the significance of SSD trim support. Therefore, as long as TRIM is enabled on the system (via trimforce for 3rd-party SSDs, see karoluss answer), you dont have to worry about it. In this regard, various SSD manufacturers also present secure erase utilities you can easily reset your SSD to a factory state using such handy tools. On APFS, macOS automatically performs a TRIM operation on the free disk space on boot via the AFPS Space Manager (spaceman). The secure erase process isn't confined to HDDs in fact, it works perfectly on SSDs also, but you might need to implement relatively different approaches to perform a secure erase SSD process. ![]()
