[05:58] <mapps> hi;
[05:58] <mapps> morning;]
[10:20] <brobostigon> morning boys and girls.
[11:44] <Myrtti> is there any point in running shred on ssd's?
[17:13] <diddledan> Myrtti: it would probably either be straight no-op or lessen the lifespan a teeny bit over just removing the file and using trim
[17:14] <diddledan> either way it wouldn’t actually “shred” a file
[17:15] <Myrtti> we ended up using hdparms secure clear whatever thing
[17:18] <diddledan> I think that just forces trim commands to be atomic rather than queued
[17:18] <diddledan> IANAL tho :-p
[17:18] <diddledan> queued/batched
[17:20] <penguin42> secure clear is the only way I'd trust for actually wiping
[17:20] <diddledan> I think trim on it’s own just tells the drive to remove the data during a maintenance cycle that it schedules internally
[17:20] <penguin42> or more that it's available if it needs to reuse it later sometime
[17:21] <diddledan> whereas I think secure clear makes the drive actually do the job immediately
[17:22] <diddledan> and again, IANAL
[17:25] <diddledan> aah, secure erase kills the entire drive rather than just bits
[17:25] <diddledan> https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase
[18:14] <zmoylan-pi> i thought the way ssd's worked there was no absolute guaranteed way to securely erase a file as wear balancing might write the overwritten variant in a different location on the drive?
[18:17] <awilkins> Yes, that was my understanding also
[18:18] <zmoylan-pi> your only real way to do it was to bung in it woodchipper fargo style... :-)
[18:19] <awilkins> Or make sure you never put unencrypted data on it
[18:20] <awilkins> Question : does anyone have a reliable recipe for getting 4oD and Demand5 to work on Wily?
[18:21]  * penguin42 has never managed Demand5
[18:55] <Myrtti> woo, so I've unknowingly been doing right on my laptop just out of the old Nokia subcontractor habit, while husband did it wrong
[18:55] <Myrtti> whaddaya know
[18:56] <brobostigon> :)
