USB 3.0 what a joke: The ports seem to have died and reverted to USB 2.0.
The ports seem to have died and reverted to USB 2.0. Always happens with USB hubs, they go bad after a couple of years.
Nice while it lasted RL |

Five pins for USB3. Four pins for USB2. USB3 is one of those low amplitude interfaces. Should work similar to PCI Express or SATA, as they all like the low amplitude differential stuff. PCI Express, at least some chipsets, are poorly protected against static electricity. On the other hand, a few manufacturers, they've managed 5kV or 6kV resistance to ESD on their USB2 ports. It's possible the USB3 ports are a little bit more sensitive to static. As long as you stick with the USB3 ports on the rear of the computer, they have the best infrastructure for resistance to ESD events. Front ports tend to be embedded in plastic, and the discharges end up flowing in the cable (which you don't want). But just as likely, your driver has gone missing. Have a look in Device Manager, for evidence of a USB3 driver. http://en.wikipedia.org/wiki/Extensi...ller_Interface "Support for all speeds[edit] The OHCI and UHCI controllers support only USB 1 speed devices (1.5 Mbit/s and 12 Mbit/s), and the EHCI only supports USB 2 devices (480 Mbit/s). The xHCI architecture was designed to support all USB speeds, including SuperSpeed (5 Gbit/s) and future speeds, under a single driver stack." Sometimes, in the driver files, you'll see those labels used for the drivers. So you can figure out what flavor is loaded right now. Since I don't have any USB3 here, I can't give examples of what's loaded on my system right now for USB3. With conventional USB 1.1/USB2 ports, you'll see an entry for each of them. The "Enhanced" entry is EHCI, and is for USB2. I don't know what the xHCI would look like, in terms of labels. This example, looks like a non-Microsoft driver for USB3. https://s3.amazonaws.com/satisfactio...sas_inline.png For comparison, this picture shows a broken Microsoft-owned driver on Windows 8. As opposed to a proprietary one. http://en.community.dell.com/cfs-fil...F00_023418.png They didn't get any help here, for that previous picture. http://en.community.dell.com/support.../19508937.aspx OSes other than Windows 8, might be relying on the proprietary driver (Renesas/Etron/Asmedia/etc).

Nice while it lasted RL - I've heard some pretty wild stories about USB3 for a SSD interface. Outrageous speeds. But it'll revert if not nailed right the first time within USB3 specifications. Class 10 flashsticks, I get 30Kb/s @USB2. . .50 to 100Kb/s should be possible to sustain with USB3 and the right gear. Flashsticks actually heat up at those speeds (probably cook, too - no reversion necessary). |

RL Thanks to all replies. I'm pretty sure after double checking that it's a hardware problem. See below on some interesting USB bugs, and apparently Win8 fixes USB 3.0 a bit. RL The Doc has seen motherboards that lost track of the boot drive because a USB drive was inserted Maximum PC, Holiday 2013 edition Missing Boot Sector; RAID 0? One day I came home as nor- mal, started up my comput- er, and it turned up a black screen, with nothing on it but the words "Missing Operat- ing System." What could have caused this? I have my OS (Windows 7) loaded onto a 120GB SSD. My computer still recognizes the drive, however, it can't find the OS. I doubt it was caused by a virus (I run MSE every time I start my system) and I hadn't downloaded or installed anything recently. The first time this happened, I shut down and disconnected/ reconnected the drive, and it worked. But that only worked once. I tried it again the next day, and I couldn't get it to start. I have no idea what could be wrong. I was going to boot the installation disc, and run the "Repair my computer" option. Would this work, and save my data? I don't have much important data on my SSD, (most is on my HDD) but I still don't want to lose it. Also, I'm running out of room on my SSD, so I bought an identical SSD to RAID 0 with my current one. Howev- er, I did not realize how much trouble it is to move an OS between drives. What do you think is the best way to RAID 0 my SSDs while still keeping my OS the way it is? Jackson Gray The DocTor responDs: Take the path of the least resistance. First, disconnect any external USB storage devices you haveUSB keys, USB hard drivesany external devices that may have confused the boot. If that doesnt work, go into the UEFI/BIOS and check the boot order to make sure it hasnt changed. The Doc has seen motherboards that lost track of the boot drive because a USB drive was inserted. After that, running the "Repair my computer" option from the installation disc is a good next step; if you have a problem with your boot sector, that'll identify it and hopefully fix it. If not, it could be a problem with your SATA connection. Try replacing the cable with a different one. Finally, the worst-case scenario is a failure of the SSD itself. SSDs are resistant to vibration and shock but their long-term reliability is proving to be the same as a hard drive. Many people make the mistake of believing that SSDs are infal- lible and forego backups. Oftentimes, the actual con- troller on the SSD will fail. Data can be recovered but its usually left to professional data-recovery services. Lets hope its not that and you can see the drive. If you can't repair the boot sector using Windows repair option, try booting your computer from a live CD to see if the drive itself shows up. If so, copy as much of the data off of it as you can. As for running out of room, you're probably better off skipping the RAID and just adding the new SSD to your computer as a separate drive, especially if you're having problems with your first one. To get your cur- rent image onto your RAID, you'd have to write an image of your whole disk, includ- ing boot sectors and hidden partitions, to an external drive, set up the RAID, and write that image back to the RAIDed drives. Keep in mind that any problems with either of the drives renders your whole RAID a bust, so the Doc suggests you cut your losses and just add the second SSD as a separate volume, at least until you pin down the problem with your first SSD. The DocTor responDs: As we noted in our review (http://bit.ly/PCitPe), "Windows 8 performance is generally the same as Windows 7, with a performance edge in anything that uses the Windows Media Foundation and likely anything that is heavily multithreaded. USB 3.0 is also markedly improved." You can see a more detailed explanation in the link above. Because Win8 is built on the same code base as Win7, nearly all hardware and software that works in Win7 should work in Win8. We haven't seen too many instances where something suddenly stopped working in Win8, but if there are specific programs and hardware you rely on, you should check the manufacturer's website before upgrading. As for the Maximum PC staff, they're split down the middle. Three editors use Win7, and three use Win8, although two of those use Classic Shell (www. classicshell.net) to bring back the Start Menu |

If it's a software problem, the problem could be gone with a different OS. With a hardware problem, the problem would still be there. You can use iotop to measure transfer speeds, and get some idea which USB standard the Linux LiveCD is using. Also, take a look in the BIOS, to see if there are any USB settings that might be flipped. Paul |
