Below is a short experience description with the Asus E-hammer.


Going by Asus website only drives: DRW-24B3LT and DRW-24B1ST support E-hammer software.

Since these drives are not really available new in the EU, firstly I tried the Asus DRW-24D5MT drive in the hope that it might support E-hammer and is just not listed, since E-hammer is from Windows XP era.

No, DRW-24D5MT does not support E-hammer. Then I got a new DRW-24B1ST from US, since a used desktop optical drive market is not really a thing.

Used a SATA to USB adapter to connect the drive to the computer. E-hammer works with both Windows 10 and 11.

E-hammer utility is a blast from the past, where its interface is based on some images. Anyway... The facility is really basic, provides just two options - Easy Delete and Total Delete.

Easy Delete destroys only the Lead-in and Lead-out areas of the discs. Leaving the disc unreadable by the operating system, but potentially the data could be recovered, since it is not overwritten.

Total Delete destroys the slightly larger disk area than where the data is. This can be visually seen as the area of the disc that has "different color" extends past the original burned data area.

It takes up to 3 minutes for a full disk destruction. If only a few MBs are used up then the process is significantly shorter - up to 30 seconds per disc for 50MB of data.

After "erasing" the disc, it shows up as a blank disc, or the drive thinks there is no disc inserted.

During testing/destruction of discs, Asus drive struggled with DVDs. It might have been my setup, but the E-hammer just did not do anything when a DVD was in the drive.
