Question: After wiping my hard drive in CCleaner there was initially still 230MB of “used space”, which has now increased to over 300MB, even though there’s literally nothing on the drive. SpaceSniffer shows it as “Unaccessible Space”, and the CCleaner analysis tool just calls it “Other Files”. I cannot see anything on the drive at all.
I’ve wiped the disk clean, formatted it, deleted the volumes. Nothing I do gets rid of it.
What’s going on with this?
Answer:I’m not sure, but looking at the documentation for DiskWipe, it says that it only wipes Windows partitions, so it is almost certainly not erasing the whole disk.
There are several wipe programs on hddguru.com. Take a look at http://hddguru.com/software/Wipe-My-Disks/
Do be careful with it – it looks like it erases all the disks in the system by default – maybe unplug any disks that you want to preserve.
Good luck.
