  1. Thanks Jaclaz! I'd need more evidence before involving little green men in this story (or elsewhere). And I'd like to know why a mobo with a new battery should lose the date. Or even two mobos. So I'm still interested in testimonies: did other people observe an abnormal clock reset on their mobo? Thank you!
  2. Hi everybody, nice to see you again! I had imagined that resetting a computer's clock might be a way to weaken its encrypted communications, especially if they are as poorly programmed as what the cited webpage gives as an example. Recently at my close relatives, two computers have shown abnormal clock resets. At my old mother, the Cmos' battery was empty. I replaced the battery with a new one from a reputed brand bought in a closed package a quarter hour before, I set the clock, and the computer worked properly. A week later, this computer lost the date again. The computer was fa
  3. Thanks Jaclaz! Yes, that's about what I plan. I had already good Apacer Cf, though I didn't use them for very long. Good experience with Transcend EXCEPT that in their 300x 8GB, they put Mlc chips without warning and contrary to their datasheet that promises Slc. Recently, two Toshiba 32GB 1000x went broken at the same time on two different readers - still not understood, maybe a high-tech Usb virus. So I consider Sata instead of Usb. I already had an adapter, or cartridge, for Ssd on Sata. My bad experience is that the connectors went broken after months, with random bad contacts. A
  4. Hello everyone and everybody, nice to see you again! I consider switching from CF (on USB reader) to CFast Flash cards. Has someone experience with them? From what I understand, the electric interface is Sata/6000 or Sata/3000 but the connector differs, needing an adapter card. Correct? Is there any bad joke with Sata and CFast, like the varied signalling voltages that plague CF cards? I plan to buy some Chinese adapter card, as they comprise essentially two connectors and copper lines in between, plus seemingly a regulator. Thoughts? The CFast cards I covet have 32GB and S
  5. My answer is late and sketchy, sorry... I only tried Nt4 briefly, so this is more repeating what I've read than first-hand experience. Most slipstream tools for 2k and later base on the slipstream capability that Microsoft built in the updates. This did not exist for Nt4. Nevertheless, some enthusiasts did write software to slipstream updates into Nt4, including the Sp6a. Do I remember that at least 3 such exist? I don't have my notices here. I saw a workaround, using an F6 diskette, to provide Lba access to a disk right from the beginning of an installation. Possibly a servicep
  6. Not necessarily. The weakness results from the CPU restoring imperfectly its state when an exception occurs. Speculative execution makes restoration difficult, but alone it doesn't imply a weakness. From Intel's list, the Core 2 for instance seems immune, with the design flaw beginning at Core i3/i5/i7. I trust Intel's list (...which can evolve) better than arbitrary claims from other sources, which often rely only on the presence of speculative execution, a very old feature indeed. I wonder: exceptions occur much more frequently than after a violation of memory protection, incl
  7. In the very few past hours, eBay and Paypal show the same symptoms of bad operation as during the two last attacks by Wannacrypt and its successor. Just in case a new wide attack has started, take your precautions!
  8. I've just tried on a 32 bits Windows Seven that I installed minutes before alone on its disk. I suppose the session has administration rights because it accesses the Device Manager. Nearly the same happens as with W2k and Xp. Minor change: Seven installs its v6.1 driver when I insert a CF and runs long enough to show me it comprises disk.sys and partmngr.sys, after what it freezes too. Disconnecting then the reader doesn't heal.
  9. Meanxhile I've had a Firewire 400 (1394a) reader from Lexar. It worked right after connecting to my mobo (chip TI Tsb43ab23), without adding drivers, on W2k-Xp that brought the OHCI drivers, and on Linux (Ubuntu 14, GPartEd and others). Said to be fast, but it was slow on my computer. I can't exclude that Lexar changed the chip over time. Sold again. I've just received a FW800 (1394b) card on Pci-E and a CF-card reader on FW800 and they don't work. Please help! ---------- The Pci-E card is a new Iocrest SY-PEX30016 with a TI chip XIO2213BZAY. Both W2k and Xp install their OHCI d
  10. You can see some images where the magnetic polarisation is read at a small scale, for instance here http://aip.scitation.org/doi/full/10.1063/1.4944951 especially the Fig. 5 http://aip.scitation.org/na101/home/literatum/publisher/aip/journals/content/adv/2016/adv.2016.6.issue-3/1.4944951/production/images/large/1.4944951.figures.f5.jpeg at a perfect scale for hard disk drives.
  11. OK. The argument with the second law doesn't apply and was pseudo-science. The second law has nothing to do with puzzles, and everything to do with entropy, internal energy, temperature, enthalpy and the likes. You know, the integral of dQ/T. Now, the time needed. The attacker doesn't need to read every atom. Once he has found where the information was imperfectly erased on the whole track, that is, a bit outwards or a bit inwards, he needs to read a bunch of atoms per bit only at that imperfectly erased circle. The speed of a tunnel effect microscope can be over 10,000 atoms per second;
  12. Thanks! I'll make a test with Tor at https://panopticlick.eff.org/ . Further observation meanwhile: Paypal refuses to open a session from Tor, so there is some means to distinguish it from other browsers.
  13. I take good note of Nist's statement, paragraph 2.3 on page 6: "Basically the change in track density and the related changes in the storage medium have created a situation where the acts of clearing and purging the media have converged. That is, for ATA disk drives manufactured after 2001 (over 15 GB) clearing by overwriting the media once is adequate to protect the media from both keyboard and laboratory attack." Though, this document is from 2006. Did they have spin-sensitive tunnel effect microscopes back then? https://en.wikipedia.org/wiki/Spin_polarized_scanning_tunneling_micr
  14. What lets you suppose and even write that? I'm an expert for electromagnetism and hold two MsC for electrical engineering, including microelectronics.
  15. Now that sounds like a pseudo-science argument: "The 2nd law of Thermodynamics describes such a fact." Beware I'm a physicist and I'm easy with thermodynamics, as more people here may be. And citing that law didn't impress me Quite the opposite. Jaclaz has provided articles that did not tell what he claims. In fact, the author of the original paper still recommends presently two multi-pass erase software. Sorry but, after two pages of arguments and references, your one-line strong statement isn't convincing.
