Ideally you would have generated and saved a HASH before you copied your files as a control. Otherwise, it's just a probability game. If the HASH on copy 1&2 match, but doesn't match 3, then the probability is 1&2 are correct. If all three don't match, you toss a coin.

If you're on Windows, I recommend using Teracopy for all your file copying (always copy, never move!) and set verify on, which will perform a CRC and generate a HASH which you can then save. You can also use it to Test your files after the fact and generate a HASH.

Flash drives are the modern day floppies. Use them and when the fail, get a new one. Stick with the smaller sizes for the best price per GB.

Correct. But this thread is about drives listed on the manufacturers sites as of 11/26/23.

The best possible quality to rip to either .ISO, saving the entire DVD as an image or rip and remux, placing the video into another container. Both will give you 1:1 quality of the original.

MakeMKV can do both of these and is free.

A possible solution is VVV (Virtual Volumes View) to create an offline searchable database of your discs, then export to csv or txt and add your HASH in a separate column.

What's really scary is that even if it's just a fraction of a percent, it's still tens or hundreds of TB of what's stored there. *SHUDDER*

Really interested when we, hopefully, read the press statement from them regarding how much data was lost, even temporarily!

They're HM-SMR (Host Managed-SMR) that requires specialized hardware and software. Which is why the article clearly states they're not for home users.

Read this and link about why Dropbox and other cloud providers are using them and HM-SMR is the future for larger hard drives.

DM-SMR is Drive Managed-SMR. All the write/read activity is handled by the onboard electronics.

HM-SMR is Host Managed-SMR. All write/read activity is handled by specialized external hardware and software. They're far from the capabilities of most home users today.

The current 26TB WD Ultrastar and upcoming 28TB WD drives are HM-SMR. The upcoming 30TB Seagate is also HM-SMR.

Your MaxDigitalData (MDD) drive is likely CMR because they're almost surely used enterprise drives. However, be careful as there was a user whose drive was HM-SMR and unusable.

MDD is a division of GoHardDrive and IMO, are drives that GoHardDrive doesn't want to sell under their own name. Also Avolusion (externals) is a division of GoHardDrive and has been reported to contain used drives.

You've listed all the 3.5" consumer drives. Though WD Red is listed as a NAS drive.

Barring an unfounded conspiracy, there is no >8TB DM-SMR drive drives. There are >8TB HM-SMR drives in the NAS and Enterprise lines, but they require specialized hardware and software.

In addition for completeness, all consumer 2.5" Seagate and WD drive >500GB are SMR. The 9.5mm Toshiba L200 1TB is CMR, but the 7mm model is SMR.
