At the end of the process of formatting a large USB drive with VeraCrypt, I was told there was a hardware error that had caused corruption. Possibly a bad build block that third party software could maybe resolve. Not much on my specific c… Continue reading Unable to wipe corrupted-on-format Veracrypt USB drive (write-protection issue)
During my search for an answer to this question I found that TRIM may not be reliable(https://blog.elcomsoft.com/2019/01/life-after-trim-using-factory-access-mode-for-imaging-ssd-drives/)as well as the ATA secure erasure, some have even sa… Continue reading Is there a fullproof way to safely erase SSD data, without physically destroying it?
Suppose that VSS is enabled and snapshots exist. If I run a program to wipe the free disk space on my drive, would this delete the VSS snapshots?

I would like to be able to delete messages once, rather than three times (on my phone and two separate laptops, all linked to the same Signal account) in order to keep track of when things have been dealt with.
Is this possible? The devic… Continue reading Why do messages which I have deleted on my phone remain on the desktop version of Signal? [closed]

I’m not sure if there is already a question here about this because I can’t find anything. But I’m wondering if there are any "safer" ways to print sensitive information without leaving traces on the printer (sensitive data in ca… Continue reading Print sensitive info without leaving data on the printer
I would really like to make my phone more secure. But at the same time I want to be able to wipe it any time. I’m afraid that wiping could brick the phone/makes it unusable. So is it safe to wipe the phone directly after encrypting it?

Overwrite regular files before deleting them. Files are
overwritten three times, first with the byte pattern 0xff,
then 0x00, and then 0xff again, before they are deleted.
How does this compare to the following (use… Continue reading Does running "rm -P /path/to/file" secure erase file from a data forensic perspective when used on spinning disk?
