I have a veracrypt drive, and I regularly have to run a scan and fix on it because it's very sensitive to power cut, brutal restart, etc.
Also, it's slow. I put my firefox conf folder in it, but it slows the browser down.
Once I went full encrypted disk, but one day corruption happened, and it stopped booting. So I went back.
I’ve used LUKS, GELI, ZFS encryption, FileVault, and BitLocker across numerous drives over the past decade (albeit in different individual proportions and timelines) with no corruption problems.
I’d suggest either your SSD just loses data on power off which is a problem with some SSDs or it’s some veracrypt specific issue that I wouldn’t be familiar with.
Id encourage you to try out one of the above options.
Also, I don't have any problem with non encrypted data.
I can count at least 3 devices that are all LUKS-encrypted that are used as consumer devices daily. I trip over the power cord, I let the battery die, I drop it, I fly regularly, etc, etc. Never once had a single issue.
In fact, the single time that I've had FS issues under Linux was running under Hyper-V but that's because of the slowly-being-uncovered serious issues w/ Hyper-V.
In fact, I'm actually having the opposite issue: I have a drive that is failing and LUKS is still able to decrypt it by some miracle.
> Also, it's slow.
Modern CPUs have AES instructions built-in. I would check to make sure you're utilizing them. You should not see any slowdown when using encryption.
The encryption exposed a problem with your disks or system in general. Depending on what the problem was, the problem is still there but you are not seeing it. Now you have a possible problem and unencrypted files.
