how is the array setup in the perc manager? That determines how the OS will see the 'disks'. I say that in quotes because unless you've got an IT mode HBA, everything that gets presented to the host is effectively a virtual device behind the raid controller. If you've got all eight drives as a...

in other words, does your bill have Watts(hours) or VoltAmps(hours) on it?

total power remains same regardless of power factor. Thus power =/= power factor. Power factor alters current draw and thus parasitic loss due to impedance. And a fraction of a small number is..... a small number. On top of that, unless you're a significant industrial electricity consumer you...

circle the wagons lads, here we go again

it has to be the world's worst AI bot. Maybe a singular denial of logic attack on the forum?

High Command Timeout on Seagate Exos Drive : r/DataHoarder [BUG] Command Timeout on Seagate Exos 7E8 · Issue #687 · AnalogJ/scrutiny

somehow good advice doesn't align with your handle and avatar :P

the purpose of the top cover, obviously, is to stop all your data bits falling out and prevent corrupted apple seeds falling in. Food wrap is a possible alternative, but they found that the rats could gnaw their way through it - and you know how much rats looove data!

if you can get an m.2 to pcie slot adapter, why aren't you just putting an ordinary HBA on one of them? M.2 to PCIe x16 Graphics Card Adapter Cable With SATA Power Cable Accessories | eBay Australia

you young whippersnappers - my first disk was so ancient you had to twist the magnetic particles by hand! It's the whole reason these plastic tweezers were invented. Your biggest corruption likelihood came from sneezing!

just some things to think about 1. Are you cabling the shelves correctly? upload to download for example not upload to upload between chained shelves 2. Are all shelves running the same IOM? 3. Are all running the same firmware? 4. Are the cables working properly? Are they connected to the...

if you heat the drive to at least 160C in the oven for a minimum of 30 minutes, you'll cause the magnetic particles to crystalise and your data will become immutable just like writing on stone tablets. You can turn an old cheap drive into one of those new fancy heat assisted HAMR drives - but...

don't you ever give up? Along with all your other silliness, you're now actively trying to sabotage yourself? Answer is no - the coercivity of a hdd is not realistically affected by a small speaker at the distance you could reasonably get to it. Most of those speakers were shielded anyway given...

I think the bitrate of a piece of knotted string leaves something to be desired! :P It's probably pretty impervious to electromagnetic bit flips though :D

just FYI, ZFS has a "copies" property which will increase the number of copies of any block to a value you specify. In practical terms this means a 6TB disk becomes 3TB with copies=2 and a 2TB disk with copies=3, but it means a single disk can recover from bit errors subject to the mechanics of...

no Bcachefs, Btrfs, ReFS and ZFS – file systems that perform automatic file integrity checking using checksums ( Checksum - Wikipedia )

I still can't believe you're flogging this dead horse over and over. Surface tests won't tell you much about file integrity. It tells you whether the drive is working as expected. You could have corrupted files all over it (written that way, bad cables, bit rot etc etc) and a surface test won't...

you keep bringing up the same stuff and it's all related to "i'm paranoid about data stored on a single "as cheap as i can find" external hdd". How can I check that my data will last forever with no backups and no effort on my part". SHA256, CRC, and MD5? are hashes. Unless you have an...

My earlier comment was based on the fact that the 2008 is the common 'published by the OEM to have alternate IR/IT capability'. In IR firmware they only offered RAID 0,1,10 levels. The 2108 and 2208 were not advertised by the OEM as changeable and came with additional raid 5,6,50,60 modes. A...

You can crossflash a 2208 to IT mode ( Guide: Flashing H310/H710/H810 Mini & full size to IT Mode | ServeTheHome Forums ). If you're desperate you could dig up the technical specs ofo both for a compapre and do some legwork based on fodeesha work. Otherwise, you're probably down to just...
