Anyone got experience on how long it takes to completely erase an 18TB HDD full of RAW video and image files? I want to use dban.

erasing 18tb HDD
that's a lot of cp
Step 1: seek help for your paranoid pedophilia
>18TB
>a lot
do you even uohh?
i had a 16tb and it took over a day for a full format
Ballpark 36 hours
Why don't you use encryption, Anon? Then you only have to delete the key when the feds come.
Because I want to sell it for 100 bucks. Iam debating just to delete it, but I don't want some creep to recover some family fotos and wedding videos tbh.
He's saying if you started off encrypting secure erasing wouldn't be needed, and if I knew you spent a week "secure erasing it" I wouldn't pay a penny for it cause it put so much needed wear on it and smart stats will probably show it was thrashed
If I don't provide a smart Screenshot nobody will buy it. Is there anotother possibility to erase the files which don't trashes it?
Nobody is gonna buy a used drive that large unless they too plan on using it for a crime.
I would buy it for general pirated media storage. New HDDs are expensive and I'm poor as shit.
Apply fire to the disk, it will flip all 1s to 0s in seconds
single pass is 300-700 GB/hour depending on the linear write speed
Would this be enough to keep some random buyer to recover my files?
yes, a single pass is more than enough
if it was encrypted from the start, you could just secure-erase the encryption key, rendering the rest of the data unrecoverable even if you leave it there
>a single pass is more than enough
No, it very well isn't. Why on God's green earth would you commit to lying outright?
>No, it very well isn't.
On modern drives it is, yeah. Maybe in the 90s they might have been able to read your data with an electron microscope, but not with the density HDDs are at nowadays.
it depends on the sequential write speed
like say it does 150MiB/s
; ((18*1000^4)/(150*1024^2)/60^2)
~31.78914388020833333333
that'd take ~32 hours
It's around 190 so according to your formula 25h. Assuming your formular is single pass. Thank you anon
yea, single pass
9 times longer than 2 TB?
Also, use LUKS next time (easier to erase - and erasing just the LUKS header, or first few MB of partition to be sure kills it hard).
Do a regular 1 pass too to be sure just in case (or if SSD then must erase all butstill might not be enough - then burn password to LUKS)
Hammer it and microwave the remains
OP probably has reasons to want to erase it instead, but I always use my old drives to make back-ups.
Can never have too many back-up drives!
I only destroy drives when their capacity and speed becomes too small and slow to make back-ups comfortably.
Currently anything up to 1.5TB got destroyed and anything 3TB and up I kept.
Yeah I want to sell it. But people say single pass erase would trash the HDD and show it on smart. Any experience with that?
a single pass will just add 18T of writes to the drive, not exactly a lot for an 18T hdd, that's one extra write per sector
So I can do that and people would still buy it after seeing the smart Screenshot?
yes, it's fine
>worried about written data on HDD
It doesn't matter, bro. If someone is checking the SMART data, they're looking at the power-on hours and if there are bad sectors.
The writes don't matter on a HDD. Writes matter on SSDs because the cells have a limited number of cycles.
Probably same as restoring a failed RAID drive.
I once had to restore a 6TB drive in a failed RAID 5 and it took about 30 hours.
But your 18TB drive is probably more modern with higher write speed, so my guesstimate is 20-60 hours.
use a bash script to do it
write all 0s, then all 1s to it
then erase, if you don't trust that shit just do it several times
and if you don't trust the all 0s and all 1s then write random combinations of 0s and 1s
oh so it's not CP? then just format and call it a day
Formatting doesn't wipe data.
Even if you have nothing sensitive on the drive I would erase it just in case some personal data got on.
just disassemble and hammer down disks.
drill a hole in it
5 seconds by running a neodymium magnet over it several times.
30 seconds in the microwave should do it
The federal agents will arrive before you manage to erase all of the data, you're fricked.
>dban
why isn't just zeroing it out better?
somethibg something magnets remember past states something something
how many past states?
About 0.05
source? 1/20th? thats a fricked up thing. 1/20 of my data can be recovered? is that a good thing?
I just erased a fairly fast Ultrastar HC530 14TB, and it took just a hair over 35 hours. Expect yours to take longer than 36 hours, up to 48 hours with proper secure procedures and then zeroing all the bits.
