Hi.

Since the latest update of the Sysinternals Suite, when I run Sdelete (v 2.0) on my disk, it hangs at 100% and does not end (command is sdlete.exe -c -z- r <drive>; OS is Win10 Pro, current updates applied; no recent changes to other drivers or firmware). I have this issue on two machines and since i run SDelete from within a script, it stops my automation process dead since i have to manually end the process now.

Any ideas on how to get this fixed?

you can try and capture a process monitor log and see if it reveals something.

Yes, I should have come to that conclusion myself ;)

Process Monitor shows ongoing write-access to a temporary file ("c:\users\<name>\appdata\local\temp\sdeltemp1") with a steadily increasing offset.

I suppose this is "new" behaviour of SDelete. It grabs free space with creating a temporary file and then works on that. Unfortunately though, that this leads to showing 100%-status for most of the processes runtime.

I'll consider this closed with the comment "misleadingly shows 100%-status"

Here's some objective test data comparing v1.61 and the newly released v2.0 of SDelete.

---

Timer 1 on: 19:45:02

SDelete -z E:

SDelete - Secure Delete v1.61
Copyright (C) 1999-2012 Mark Russinovich
Sysinternals - www.sysinternals.com

SDelete is set for 1 pass.
Free space cleaned on E:\
1 drives zapped

Timer 1 off: 19:46:28  Elapsed: 0:01:25.50

Timer 1 on: 19:46:28

SDelete64 -z E:

SDelete v2.0 - Secure file delete
Copyright (C) 1999-2016 Mark Russinovich
Sysinternals - www.sysinternals.com

SDelete is set for 1 pass.
Free space cleaned on E:\
1 drive cleaned.

Timer 1 off: 20:28:54  Elapsed: 0:42:25.89

So yes the v2.0 version of SDelete doesn't "hang" (forever) at 100% it just does something else for 28x the time of v1.61.

PS: E: is a flash drive (NTFS formatted) with 1.10GB of free space.

To add to this we use Sdelete during builds of our virtual machine templates.  On using v2.0 I gave up waiting for it to finish after 4 hours.  After reverting to v1.61 it completed in less than 10 minutes.  I think there might be an issue.

Something is up with SDelete 2.0..  I use it to zero the free space in a VM and it's VERY VERY slow compared to the older version.  What's the previous release?  1.6.1?  I need to find a copy...

I have the same problem with Sdelete on my SSD.
The resource monitor showed v.2 writing the disk at approx 40Mb p/s
while v.1.61 at 1,300 Mb p/s 

SDelete v.2.0 is faulty (shows 100% all the time) and dead slow, don't use it.
Google v.1.61 , it works just fine.

Same problem for me.
About 15 MB/s zeroing our virtual disks with 2.0 instead of 150 MB/s with 1.66

I've also submitted this to Mark. He said he's going to look at it. So wait for a fix
