SSDs are complex beasts :-)
I've had an OCZ SSD in the past that also became read-only, in the sense that all changes after shutting down the computer were gone.
If you rebooted everything was fine, but as soon as the computer was shut down and the SSD also ran out of power, it converted to the state before turning on the computer. That was so bizarre. Once I had a hefty Windows upgrade installed and it was gone after the reboot - as if I had never installed it. It also took me a while to realize it because first of course you start to doubt your own memory, you don't realize that the sector- mapping on the SSD has suddenly become read-only
OCZ eventually solved this via an RMA and eventually OCZ also went upside down. The Time Warp bug it was called I think.
- mvdwoord 4y agosounds ideal for a public terminal ;)
- csdvrx 4y agoMarketing should make that a feature: hardware-guaranteed non-modifiable root filesystem! Better than Nix!
- totalZero 4y agoNo updates! Ever!
- ashirviskas 4y agoAlso, no malware!
- sebazzz 4y agoThere used to be a PCI module (iirc) that would assist in that. I believe it was called a Bo(u)rne Again module. It was used in school computers etc.
- AdamJacobMuller 4y agoThere was an IDE dongle which did this. It was at a school I was visiting (but not my regular school) and it was pretty cool because it allowed them to be pretty liberal with permissions on the computers since you couldn't really do anything terrible as a reboot would fix everything and they powered them off every night.
