No, that should be fairly quick, depending on the speed of the machine, of course.Klawdek said:I only have about 11GB of free space so I am hoping that wont take long to do.
The only issue I have with 6.1.0.2241, which is what I am currently using on both of my main machines, is that I cannot erase free space and cluster tips on a system drive,
Any of the recent ones should be OK. As I write, 2244 is the most recent. I'm using 2241.Klawdek said:So which 6.1 version that can erase free space do you feel is most stable?
The latter. Erasing cluster tips is an option of erasing free space; there is not much point in doing the first unless you also do the second. On a system drive, I get a crash if the option is set.Klawdek said:Do you mean that it cannot erase free space and/or cluster tips, or that it cannot erase cluster tips but still can erase the free space?
Did you double click the task and see if any progress was made?Klawdek said:I tried 2247. As you mentioned it cannot erase cluster tips. It does not crash it just hangs. After 2 hours with no new entries in the task log for the last hour I canceled the process.
Unfortunately that's not the case. Your anti virus doesn't need to open and close file handles four or five times a file. In addition, your anti virus does not write to the file at all. Eraser needs to:Klawdek said:I figure it should not take more than two hours to erase 10GB with cluster tips. My anti virus can go through every file in the system and do 100,000 more things to each file than eraser does, in two hours or less. So I figure eraser should be able to erase cluster tips in a fraction of the time.
If you have volume shadow copies, space is freed as the erase continues. The system deletes old system restore points a the amount of disk space decreases. If you're using a decently new drive, in 20 minutes approximately 72GiB of data should have already been written. There are a few possibilities: either you had that much space used for system restore, or more likely, you used an erasure method of more than 1 pass on the unused space.Klawdek said:Then I tried erasing free space without the cluster tips option enabled. This time it took 20 minutes and completed with the following warning:
Warning This computer has had System Restore or Volume Shadow Copies enabled. This may allow copies of files stored on the disk to be recovered and pose a security concern.
20 minutes is still extremely long for a write of 10GB. I can write 8GB of data to a DVD in 20 minutes and that is the slowest data storage medium in common use today, I do not understand how writing 10GB of data to the HD could take more than about 2 minutes.
Defaults are set in the Settings. Depending on the type of erasure you are running, the correct setting will be looked up.Klawdek said:The default options are a bit screwy. The first time I ran it the default erasure method was set to Gutmann 35 pass. I changed it Pseudorandom 1 pass. The next time I ran it it was set to default with no indication what that means. I changed it to single pass.
Not necessarily. 35 passes would be around 350GB of space. Even on a very fast drive (~105MB/s for a new Barracuda) that would require at least 56 minutes to complete. When running the task, double clicking on the task would yield quite a bit of information. Perhaps you may want to look at that (and capture a screenshot while you're at it) for details.Klawdek said:The thought occurs to me that somehow it could have done a 35 pass instead of a single, That would explain the enormous amount of time it took. Unfortunately the task log does not indicate erasure method (he should really put that in there).
