• External Hardrive Not Reconized on Windows 7 at all

  - by Bella

  I Have a NextStar 2/5" from Vantec and its an 80G HD. I have used it many times on windows xp and it works fine. We just recently upgraded to windows 7 home premium and when I plug it in it beeps many times. I've tried all the USB plugs in my computer and its not those plugs. Haven't tried eSata because it uses a weird cable to plug into. People told me that when it beeps everything is corrupted, but works fine on xp. I tried installing the drivers online from their website and when I try it asks me to put in a cd which makes no sense because they are online drivers. When I go into device manager nothing comes up, it just acts like the HD is invisible. The beeping will stop eventually as it is plugged in, but with no result.

• Enabling the log app on the WDTV

  - by Ariel Popovsky

  Just flashed the last WDXLTV firmware on my WDTV and it's working fine. I tried to config a Wifi USB adapter but couldn't get it to work. Dropped the log-saver.app.bin on the root of the stick but didn't find any log files after booting. What I'm doing is turning on the WDTV with the stick inserted (the stick is formatted with FAT32). Tried with the wireless-mod.app.bin required files and without any other file than the log saver. I can't get a log file anyway. All I want right now is to get the log file so I can debug the WI FI adapter.

• Wireless Keyboard Intermittent Failure to Type and Added Characters

  - by Kashif

  My keyboard has been acting up from time to time. It's wireless so this may be a wireless issue. What happens is I will be typing and then all of a sudden it seems to stop responding. If I type out this sentence it may show up like so If I ttennnnnnnnn it may ssssssp so While typing that sentence I may have to mash on a key repeatedly to get it to type. The resulting strings of letters seem to be coming as if the keyboard buffer cannot keep up. It's so weird. If I take the USB tranceiver and yank it out then plug it back in, Voila! Problem solved. I did the battery check so that's not a problem. Any suggestions? My keyboard is the Logitech MX3200

• Refresh devices - reconnect CF card drive by script (unplug-plug equivalent)

  - by Chris

  Hello I plug a completely clean CF-card into my USB card-writer. Then I dd a mbr block of 512 bytes size to the device, which contains the partition table and the definition of one partition. Problem: While "fdisk -l /dev/sdx" correctly displays the partition, it happens that there is no device like "/dev/sdx1" after these operations (as it was not present before). Unplugging and plugging the card-writer solves the problem and makes the device(s) appear. Since I use this procedure in a script, manually unplugging and re-plugging is no option whatsoever. Is there a way to "refresh" the devices or to "unplug and re-plug" the drive by script such that /dev/sdx1 appears? Thanks for any help, Chris

• "Windows was unable to complete the format" - Can't format flashdrive!!!

  - by Jake

  I have a 8GB Sandisk Cruzer USB flash drive that I had ruined a while back trying to make it bootable. Anyway now when I click on it I get a message that it needs to be reformatted to be used. So when I try to do that, the formatting starts and suddenly ends with the message "Windows was unable to complete the format". This happens no matter which file system I choose (NTFS, FAT32, exFat) and also which computer I try this on. I am now on a Windows 7 32 bit OS and before tries it on a Vista Home Basic machine. Anyone know any way around this issue? Many thanks.

• fsck: FILE SYSTEM WAS MODIFIED after each check with -c, why?

  - by Chris

  Hi I use a script to partition and format CF cards (connected with a USB card writer) in an automated way. After the main process I check the card again with fsck. To check bad blocks I also tried the '-c' switch, but I always get a return value != 0 and the message "FILE SYSTEM WAS MODIFIED" (see below). I get the same result when checking the very same drive several times... Does anyone know why a) the file system is modified at all and b) why this seems to happen every time I check and not only in case of an error (like bad blocks)? Here's the output: linux-box# fsck.ext3 -c /dev/sdx1 e2fsck 1.40.2 (12-Jul-2007) Checking for bad blocks (read-only test): done Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information Volume (/dev/sdx1): ***** FILE SYSTEM WAS MODIFIED ***** Volume (/dev/sdx1): 5132/245760 files (1.2% non-contiguous), 178910/1959896 blocks Thanks, Chris

• Is there a Linux-compatible R/C simulator that works with real radios?

  - by Norman Ramsey

  My Dad flies radio-controlled (R/C) aircraft. He used to run a simulator called "RealFlight" which allowed him to connect his actual radio to his computer and fly simulated craft. He learned enough to fly actual planes, but he wants to move up from "trainer" aircraft to higher-performance craft. After some crashes, he'd like to go back to the simulator for a while. The catch: he's given up Windows and is now running Ubuntu. Question: is there an R/C flight simulator that Runs on Ubuntu? Allows you to connect your radio and use it to control the simulator, preferably through a USB port?

• Partition Bootable Flash Drive

  - by iAndr0idOs

  I created a bootable flash drive with Chromium OS installed on it. However, Chromium OS only needs about 4GB of space, and my flash drive is 8GB. I wanted to make the rest of the 4GB a FAT32 partition, but when I look at GParted, I have 12 different partitions on the flash drive with unallocated space scattered everywhere. I made the bootable flash drive with Ubuntu Linux's usb-imagecreator I run Ubuntu Linux 11.04 x86_64 and Windows 7 Professional x64 If any of you have experience with this, any help would be appreciated. Thanks!

• Detecting/Reactivating serial port that becomes inactive on Ubuntu Linux 10.10

  - by Tom

  I am using a usb2serial port to communicate with some old equipment (using my code built upon the boost asio library - I think my code is fine because it works almost all of the time). Every so often (maybe once every few days) the communication stops with my device with no error at all - the device just does not respond. I then restart my computer and everything is fine again. Does anyone know where I can start to analyse this problem? My serial port loads up fine (in /dev/ttyUSB0) and the boost library does not throw an error. The device just does not respond. If I restart the device no change - only when I restart my pc does it make a difference. I have also tried unplugging and replugging the usb connector. Does anyone know what gets cleared in the reboot (w.r.t the serial device) or what I can probe when the problem happens again (rather than just restarting with hope)

• SD card mounted as bootable image instead of FAT 32

  - by Benny Wong

  I have an SD card that I recently used to take photos on vacation. It have taken a lot of photos using it and worked fine on the camera. However, I had forgotten that a few months before this trip, I tried to make the SD card a bootable Xubuntu USB drive. So when I plugged my SD card in to copy the photos, the card mounts as the Xubuntu image, rather than mounting as the FAT32 drive with the images on it. The files must still be on the drive. Any ideas on how to fix this? (I'm using Mac OS X) Thanks!

• Why does my computer slow down so much when attaching Bluetooth dongle?

  - by Jeff Yates

  I have a Bluetooth dongle and I plugged it into my work laptop (a Dell Latitude D830). Windows detects the Generic Bluetooth USB or similar and then proceeds to go incredibly slow with a process, avp.exe¹, taking 50% CPU. The System Idle process is getting most of the other 50% CPU and the avp.exe process is only at Normal priority. The machine doesn't seem to recover, so I had to turn the power off and reboot. Now, I haven't installed the drivers yet for the device, which I am doing now and I expect it to resolve the problem, so I am not asking how to fix this. I would rather know why Windows goes so slow in the first place. What is it trying to do and failing at so badly that it barely crawls? ¹ Part of Kaspersky Internet Security suite

• HP ProLiant DL320e G8 v2 - USB2.0 during POST

  - by user3513346

  Initially my USB2.0 ports were working during POST (and boot). However, now they appear not to be. I first noticed this when I could not access the RBSU by pressing F9 during POST. Then found that I couldn't boot from USB either (I was able to do both of these initially). When performing the boot via iLo remote console I can access all of the setups (i.e., all of the F(X)'s) and can boot virtual media from a 'removable drive'. Keyboard works fine once the OS is booted. Not really sure what to try here. Any advice would be greatly appreciated. Thanks. Nick.

• In what way does non-"full n-key rollover" hinder fast typists?

  - by Michael Kjörling

  Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

• Making backup of the System Restore Partition with netbooks

  - by devoured elysium

  I have a netbook that has two partitions. A first one where I have all my programs and stuff and a second one that came with the netbook and has the data so I can restore my computer if I need to. Now, as I had problems in the past with other computers that had a similar restore scheme, I know I must in some way do a backup of this partition, so if there is any problem I can put everything working again. How should I proceed? As this is a netbook, it doesn't have a CD reader. Maybe doing a backup of this partition to a 12GB(it seems this partition occupies this much!) usb? How could I do it? Thanks

• Just bought Logitech G35 headset, want to enable/disable headet in one action

  - by Roy Rico

  Hello, Just bought Logitech G35 USB headset, want to enable/disable headet in one action. I have windows 7 64 bit, and currently, to switch from the headset to my spakers (or vice versa) without unplugging the headset, i have to go thru this steps: right click on the sound icon select "sounds" select the "Playback" tab right click headset and hit enable right click speakers and hit disable same steps when wanting to switch back I have to disable the devices, because not all of the programs which are outputting sound will switch immediately if I just set either device to default. I am looking for this to be a single action (either a batch script or a windows shortcut to some action with parameters?) Thanks!

• Logitech M185 Wirless Mouse issue

  - by Elliot Harrison

  An issue with a Logitech M185 mouse today. A user is unable to use the device. The device works perfectly fine on my PC (It appears as HID-compliant mouse), but not on her laptop. It does not appear in her device manager on the 'Mice and other pointing devices' section. I did notice an unknown device in the Universal Serial Bus Controllers section, but when I try to update the driver, it says it has the most up to date driver. We've tried plugging in the dongle in multiple USB slots but no luck. Any advice? It's a HP 620 Laptop on Windows 7. Thank you :)

• Ubuntu - Automatically mount external drives to /media/LABEL on boot without a user logged in?

  - by endolith

  This question is similar, but kind of the opposite of what I want. I want external USB drives to be mounted automatically at boot, without anyone logged in, to locations like /media/<label>. I don't want to have to enter all the data into fstab, partially because it's tedious and annoying, but mostly because I can't predict what I'll be plugging into it or how the partitions will change in the future. I want the drives to be accessible to things like MPD, and available when I log in with SSH. gnome-mount seems to only mount things when you are locally logged into a Gnome graphical session.

• external HDD with SATA & USB interface?

  - by Greg

  Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model. Preferably one of the name brands so I have a better change of finding it here or locally if possible. Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

• Is an Ethernet point to point connection without a switch real time capable?

  - by funksoulbrother

  In automation and control, it is commonly stated that ethernet can't be used as a bus because it is not real time capable due to packet collisions. If important control packets collide, they often can't keep the hard real time conditions needed for control. But what if I have a single point to point connection with Ethernet, no switch in between? To be more precise, I have an FPGA board with a giga-Ethernet port that is connected directly to my control PC. I think the benefits of giga Ethernet over CAN or USB for a p2p connection are huge, especially for high sampling rates and lots of data generation on the FPGA board. Am I correct that with a point to point connection there can't be any packet collisions and therefore a real time environment is given even with ethernet? Thanks in advance! ~fsb

• Ubuntu - How to automount an external drive at a preconfigured mount point?

  - by Lars Haugseth

  Normally, when I attach an external USB drive to my Ubuntu system, the filesystem on it are automounted to /media/label. However, I'd like the filesystem to be mounted at a mount point of my choosing. I've added a line like this to my /etc/fstab: UUID=2BE905C238C1F724 /p ntfs-3g defaults 0 0 # Passport 320GB This allows me to manually mount the volume at /p by running sudo mount /p, however the filesystem is no longer automounted when the drive is attached to the PC. What do I need to do to get automount to this mount point to work, if at all possible?

• Why are my flash drives getting formatted?

  - by user13743

  I've had two cheapie flash drive from Microcenter, and they booth out-of-the-blue became unformatted. When you insert then in the USB drive, windows says "The drive is not formatted. Do you want to format it now?" And then it can't actually format it. Nothing happened to them physically. For one, it 'died' during a reset, and the other, it was normal and then it was dead once when I inserted it, IIRC. What's the deal? Are these just cheap, crappy drives, or what?

• Windows Phone 8 not interfacing with Zune software

  - by Cyberherbalist

  I just got a Lumia 521 with Windows Phone 8 and am trying to get the device to work with the Zune software on my PC. I still have my Windows Phone 7 device, and the new one is not working the same way. When I plug the WP7 device into the PC's USB port, it automatically fires up Zune and I can sync my podcasts and music etc to the device. But when I plug the Lumia into the PC it doesn't fire up Zune, and if I start Zune manually, it doesn't interface with the phone at all. Perhaps I am missing something and WP8 isn't supposed to use Zune to interface with the phone?

• Prevent Windows 7 from unpluging External HDD

  - by marverix

  I have installed Windows 7 as my media server. I pluged in 500GB external HDD via USB. I have changed power plan to Best Performance and changed advenced power settings to never turn off HDD etc. I even yesterday wrote powershell script (create and delete folder on this disk) and I have added it to harmonogram to run every 5 minutes starting from system boot. And nothing! Disk after some time (I realy can't say when) is turning off and Windows show "Unknown Device" in Device Manager. Then only system reboot or disk reboot helps. Any ideas how to prevent Windows 7 from stopping my external HDD? Cheers!

• How can I create a pen drive that I can boot from, and then install Win98 from?

  - by rossmcm

  I have a HP Compaq t5515 thin client computer with a flash disk and USB port. I want to put Win98 onto it, replacing whatever is on there now (I think it is some Linux-based thing). I can find stuff about putting Win98 onto a pen drive and running from that, but I can't find any info about installing Windows 98 from a pen drive onto a sep[arate system. Is it just a matter of making the pen drive bootable to DOS copying the contents of a Win98 installation CD onto the pen drive booting the HP machine from the pen drive running SETUP.EXE from the pen drive? Any pointers appreciated. TIA

• Automatically distinguish difference between multiple HDDs in linux?

  - by Jakobud

  I'm running Ubuntu Server 9.10. I have two external USB HDDs. I use them each for different backup reasons. So certain data gets stored on one HDD, and different information gets stored on the other HDD. I want to make a script that can look at the external HDD can determine which HDD it is, so that it can copy the proper information to it. Is there a way for Linux to determine this? Like if I see one HDD as /dev/sdc1, then unplug it and plug in the other HDD, should Linux see it as /dev/sdd1 or will it be /dev/sdc1? I'm a bit of a Linux newb and I don't quite understand how it determines the /dev/sdxx values that it assigns to drives.
