Installing Donemax Data Eraser adds the program's folder along with 2 EaseUS drivers [epmdkdrv & EuGdiDrv] and their services [for safe boot?], and adds a tiny dmdeshell.xml file to C:\Windows. Besides driver-related entries, the registry gets a key for uninstalling the app., and entries are added so that Donemax Data Eraser appears in the right-click context menus. It does appear to work portably, though it adds that .xml file, and in testing for some reason rewrites the HKLM\ Software\ WOW6432Node\ ODBC\ ODBCinst.ini\ key & sub-keys -- I recorded 425610 keys written because of that. Note: because of the huge size of that log I cannot say with 100% confidence that running Donemax Data Eraser portably didn't add a significant new key or two -- I don't *think* so, but could be wrong.
From my post on the download page...
Assuming that it does clear SSDs, IMHO Donemax should provide more info on its web site, rather than just saying it doesn't shorten the lifespan. It's probably worth a shot to check it out, bearing in mind that there have been enough data recovery apps on GOTD that you could verify if files are indeed gone, though that won't tell you anything about potential data stored on blocks that are inactive because of over provisioning. Some SSD manufacturers provide their own utilities to reset the drive, but research before you depend on one of them, because some have been found not to work. Tom's has a decent article that suggests you can also use Windows DiskPart.

Erasing a conventional hard disk requires patience -- it can take a Long time. Because the read/write heads float over the platters where data's stored on a tiny cushion of air, they can wobble a tiny bit side to side. That means that when data's overwritten traces of the old data may be left behind, say if the heads were on the right when written but more to the left when overwritten. To counter that apps like Donemax Data Eraser can overwrite the entire disk more than once, and that can take a long time. To avoid that businesses sometimes use a service that actually shreds hard disks, or if you're throwing the old hard disk away, some people will try to physically destroy them, often by drilling multiple holes through the hard disk. Note: one method of recovering data from a failed drive is to install the platters from a dead conventional hard disk in a working drive, so don't assume when a hard disk fails it's safe to just toss it in the trash.
