• How do I remove a USB drive's write protection?

  - by nate

  I have a SanDisk Cruser Blade USB stick that suddenly seems to be write protected. I tried running DiskPart but after I write the command "attributes disk clear readonly" it displays this: Microsoft DiskPart version 5.1.3565 ADD - Add a mirror to a simple volume. ACTIVE - Marks the current basic partition as an active boot partition. ASSIGN - Assign a drive letter or mount point to the selected volume. BREAK - Break a mirror set. CLEAN - Clear the configuration information, or all information, off the disk. CONVERT - Converts between different disk formats. CREATE - Create a volume or partition. DELETE - Delete an object. DETAIL - Provide details about an object. EXIT - Exit DiskPart EXTEND - Extend a volume. HELP - Prints a list of commands. IMPORT - Imports a disk group. LIST - Prints out a list of objects. INACTIVE - Marks the current basic partition as an inactive partition. ONLINE - Online a disk that is currently marked as offline. REM - Does nothing. Used to comment scripts. REMOVE - Remove a drive letter or mount point assignment. REPAIR - Repair a RAID-5 volume. RESCAN - Rescan the computer looking for disks and volumes. RETAIN - Place a retainer partition under a simple volume. SELECT - Move the focus to an object. It's like when you type help at the DiskPart prompt, so how do I get past this? This problem started when I plugged the stick into a laptop which had viruses, if that's any help.

• Grub hangs at "Starting up ..." when USB flash card reader is plugged in (on Ubuntu Hardy)

  - by Laurence Gonsalves

  I have a PC with Ubuntu Hardy installed. The machine boots fine unless my USB flash card reader (one of those N-in-1 readers by MediaGear) is plugged in at startup. If the reader is plugged in, the boot process proceeds as normal until it gets to the screen that says "Starting up ...". At that point it just hangs forever. To work around this I currently leave the reader unplugged when booting, and then plug it back in after I see that Ubuntu is actually starting. This is annoying though, especially when I reboot the machine (typically for updates), forget to unplug the reader, and walk away only to come back hours later to find the machine hung. My guess is that the presence of the reader is confusing Grub about where to find the kernel. The weird thing is that Grub is on the same drive as the kernel I want it to boot so clearly the drive is still readable even when the flash card reader is plugged in. Is there some way I can tell Grub to never go looking on the flash card reader?

• Does anyone know where I could find a 2 input USB voltage meter?

  - by John O

  What we really need is a tiny UPS, of sorts. We'll be hooking up a solar cell and a battery to a single board computer. Currently, that SBC is a custom Pic32 device, and it does it's own UPS and voltage monitoring duties. I've been tasked with trying to replicate all of its features with off the shelf products... and for the most part I've succeeded. But I don't currently have any way to switch between two sources of juice, or monitor when they're getting low. These guys have something: http://www.mini-box.com/picoUPS-100-12V-DC-micro-UPS-system-battery-backup-system I really like it, the price is well within the budget. We might even work it in though it does 12V and I'll probably be using 5V... there are enough engineers on hand to figure out something. But I'd still have no idea what the voltage was for the PV or battery. I was hoping that there was some simple little USB multimeter thing that I could use to monitor this with, but I can't seem to come up with anything. I've found all sorts of cool hardware, but nothing that will help us. Does anyone know of anything?

• Gparted resize of an extended partition fails with error "can't have overlapping partitions".

  - by Marcus

  I just decided to install Ubuntu 12.04 alongside Windows 7 on my Dell laptop. However I didn't do this manually but instead used the "Install Ubuntu alongside Windows 7" option during the installation. Now the partition that Ubuntu runs in has very little space and I am getting warning messages. I'm trying to use gparted 0.12.1-5 (via a live CD) to give Windows less space and give Ubuntu more. I've managed to remove 100GB from the Windows partition so I now have some unallocated space between Windows and Ubuntu. This is what it looks like inside Ubuntu (not using the live CD, since it won't let me mount a USB to save a screenshot): So first I take sda4 (extended?) and resize it to the left so it takes up all the unallocated space. Then I resize sda5 (ext4) as well so it takes up all the new space. However, when I hit apply, it fails on the first action (resizing sd4) with the error message can't have overlapping partitions. Any ideas as to why this happens? I also tried resizing sda4 by just a few MB so that it definitely didn't overlap anything, but I still got the same error message. To clarify, I am using gparted from the LiveCD, I just took the screenshot from Ubuntu. I couldn't attach the details file containing the error information from gparted because I can't mount a USB drive when I'm running from the LiveCD. I'm tried following the guide on the gparted website but it says Invalid argument or something like that. If the gparted details are needed, I may need some hints on how to solve the USB issue as well. :)

• New Dell Vostro 3550 will not boot into Live CD

  - by rich97

  I've been trying to install Ubuntu and/or it's derivatives on my new Dell Vostro 3550 but I'm finding it impossible to boot into the live CD environment. Here are the things I've already tried: Booting from multiple versions of multiple distributions (Ubuntu 10.10, Ubuntu 11.04, Mint 11, Mint 10) Booting from a Live USB created with unetbootin, the Linux Mint startup disk creator, the universal USB creator and dd of=linuxmint.***.iso if if=/dev/sdx. Burning a CD and booting from the internal CD drive. In the case of the USB keys with the latest versions of Ubuntu it gets to the page where I can select a boot option, but after selecting an option the screen goes black, even the back light turns off. With the older distributions the screen stays on but it starts loading and then just hangs. The CDs don't even try to boot. It starts spinning but then falls back to the default Windows install. The only way I've got it to work so far is with Wubi, but that's hardly ideal. I'd like to have two separate physical partitions with a /home and /. Any help is appreciated. Thank you.

• print jobs are held until the VirtualBox guest OS is reboot

  - by broiyan

  Here is the setup: VirtualBox 4.1.20 (which the Help window describes as 4.1.12_Ubuntu) Extension Pack 4.1.20 (for USB support) Windows 7 Home Premium as a guest operating system on VirtualBox Ubuntu 12.04 with dist-upgrade's to September 2012 as the host operating system. Fuji Xerox DocuPrint P205b, which I believe is a GDI printer, connected via USB. The problem is that often print jobs will sit in the print queue and nothing comes out of the printer. The printer status for the first item in the queue will be Printing even though nothing happens. Then upon rebooting Windows, the print jobs get printed, seemingly simultaneous to the rebooting process; that is as Windows reloads. One way to avoid this problem is to reboot Windows with the printer cable attached, and then submit the print jobs. The print jobs get printed in a timely manner. Perhaps VirtualBox has a problem with USB being plug-n-play and hot pluggable. It's not convenient to have the printer plugged in when Windows boots because: One, this is a laptop, and Two, I may be boot Windows for a purpose other than printing and not anticipate needing to print. Are there any recommendable fixes for this problem?

• Connecting PS3 dualshock on Ubuntu 14.04 with 3.13.0-34-generic?

  - by 5th Wheel

  The last entries/queries I can find about PS3 dual shock controller are dealing with older kernel versions. It looks like there may still be a problem with using the PS3 dual shock via USB(or bluetooth) with 14.04? I'm only guessing because I get no sign of detection or input when I plug in the USB. When I run dmesg | grep sony [ 4687.762302] sony 0003:054C:0268.0003: can't set operational mode [ 4687.770639] sony: probe of 0003:054C:0268.0003 failed with error -38 So at this point, I don't know if it's worth running : sudo apt-get install xboxdrv I also found this article LINK but it's dated 01/2013. I was considering installing steam, and checking out some of the games. There are a few in particular I want to check out, but I'm afraid of purchasing them and then my controller does not work. I don't have a ps3, I just have the controller for Sixaxis/emulator/Android set up... I see mentions for QTsixa and xboxdrv, but the posts are at least a year old(older distibution/kernels) Ideally, I'd like to just plug in USB, and play. No Bluetooth.

• Photo transfer problems from camera

  - by warkior

  We have a digital camera (Cannon SX130 IS) which we often connect to the Ubuntu 12.10 desktop via USB in order to download the images. In past flavours of Linux (Mint 12 was most recent) it worked fine, however since upgrading to Ubuntu 12.10, the process fails after downloading a small number of the images. I can view the images which will be transferred in the preview window, and I can browse the camera file system to download the images manually, but if I just drag/drop the images over from camera to desktop, it freezes after 5-6 are copied over. I've been able to get around the problem by only copying 3-4 at a time, but when you have 100+ images to transfer, that gets really frustrating. Any advice on where I could start looking for answers, or how I could diagnose the source of the problem further? We have also had some issues with WireLess USB mice though it may not be related. I'm hoping my USB controller in the computer isn't dying... it's not that old. Also, it seems to work much better under Windows.

• Step 2 of instructions is not clear to me

  - by Albert Frye

  I want to make a bootable USB stick. I run the UUI. I see the instructions on this site: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows Step 1 says: Select "Ubuntu Desktop Edition" from the dropdown list Okay, so the actual title of the drop down box is: Select a "Linux Distribution" from the dropdown to put on your USB I am pretty new to computers. 67 years old. Live alone. Bought my first computer 3 months ago. So I will have to assume that when the instructions say "Ubuntu Desktop Edition", that means the same thing as "Linux Distribution". Okay, No big leap there. So far, so good . . . . . . . So I pick the very first selection: Ubuntu 13.10 Desktop i386 I'm not sure why there are so many choices, but I'm guessing I'm pretty safe with the first one. It's for a Toshiba Satellite laptop 64 bit Windows 7. Okay, now for step 2: The instructions say: Click 'Browse' and open the downloaded ISO file. The message in the window just before the "Browse" button says: Browse to your ubuntu-13.10*desktop*i386.iso -- Okay, so where's that file? So I click "Browse" and start looking for that file. It is nowhere to be found. So where the heck is it?

• Run script when a specific disk/memory card is mounted under OSX

  - by Max Rydahl Andersen

  How do I run a script when a drive is mounted under OSX ? My usecase is that I would like to automatically copy images from my USB memory/harddrive when it is inserted in my USB card reader, and when a DVD or CD is inserted I would like to copy it for storage in my media center. I've tried using Marcopolo but from what I can see it can only detect the presence of a certain USB device, not the presence of specific harddrive.

• installing windows XP in Samsung SENS 145 plus notebook (no CD drive)

  - by user13267

  Hi I was trying to install Windows XP in a Samsung SENS 145 plus Notebook. It does not have a cd drive and I already managed to format it and semi install Windows XP, so now it does not even boot up either. This is what I did: Since it supports USB booting, I first made a bootable USB of Windows XP (Korean version; SP2 I think, may be SP 3) using Novicorp WinToFlash enter link description here. It managed to boot up at first and I was able to format the C driveand get Windows install to start up. It took forever to copy all the files from the USB and after the first reboot, before installation started, I cancelled the reboot from windows install, went to BIOS and changed the boot device priority from USB to internal hard drive. But now on bootup it showed me a list with two options for booting windows XP (much like in the case of a multi OS system) so I assumed that I had formatted drive D by mistake and installed XP there, instead of on C drive. Anyway, I chose one of them and it continued my Windows installation. I got the blue installation screen that shows ads about Windows XP on the right frame and estimated remaining time on the left. However, after completing the process, after the first reboot, instead of showing the Windows XP logo, it says \system32\hall.dll is missing (or corrupted I'm not sure, I needed to install the Korean version of windows and I could not exactly read the error message, however it was one that I have already seen in an English version installation, and I am sure it says either missing or corrupted). The problem is, now it shows the same error again when I try to reboot it from the USB drive as well. I tried to boot a portable version of Linux I made in another USB, but the computer does not boot up from that USB, and it shows hal.dll error when I try to boot it using the WIN XP installation USB I made, as well as when I try to boot it from the hard drive, where I suppose Win XP is now semiinstalled. So now I can't get the computer to start up at all, except going to the BIOS. What else can I try to solve this? Also, would it be possible to install XP on this computer by connecting it to another one running Windows 7 ultimate, through the ethernet card? That is, network just the two computers together, then install windows XP on the notebook from the desktop running windows 7? Please help, I'm running out of ideas on this one. If Korean version of windows XP is the problem then I am willing to install English version as well. (but I need to make sure if that is the real cause of the problem)

• apcupsd on Linux does not report on APC BackUPS Pro 900

  - by lserni

  From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64).

This confirms that it's not the Microlink problem, or it would report the battery status, if precious little else. If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

• MKV video suddenly stops playing after random time - what could this be?

  - by MEM

  I have this HP USB drive (16GB, NTFS formatted) that has, a MKV video. The USB is always detectable, so is the MKV, but when I connect that USB drive with that MKV video on my HT-C5530 home cinema USB port, the playback just suddenly stops after random time, and it returns to the main menu when I can see the pen and it's contents. I really have no clue about what could be the issue here, has someone else experience something similar? That may help me out on this.

I would like to know for the vm's I run (rarely 2 at time..almost always 1 vm at a time) should the virtual hdd be on my laptops native hdd or some external form (usb hdd, usb flash, or since i have mac express card based sad ?). I don't mind maxing out my ram to 16GB if thats a better option to have in the mix. Thank you

• 13.04 Ringtail USB installation overwrote my username

  - by barnhillec

  I had to use an .iso USB to upgrade from 12.10 to 13.04 Ringtail. Great results, except the USB stick install app asked me to provide an identity so I provided the same one I used for 12.10 . Unfortunately it overwrote my other identity with a fresh one, so now I have no ownership of all my previous profiles, etc. A dumb mistake, but is there a way to take ownership of my previous user identity and merge it with the current?

• HP SmartArray P400: How to repair failed logical drive?

  I have a HP Server with SmartArray P400 controller (incl. 256 MB Cache/Battery Backup) with a logicaldrive with replaced failed physicaldrive that does not rebuild. This is how it looked when I detected the error: ~# /usr/sbin/hpacucli ctrl slot=0 show config Smart Array P400 in Slot 0 (Embedded) (sn: XXXX) array A (SATA, Unused Space: 0 MB) logicaldrive 1 (698.6 GB, RAID 1, OK) physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SATA, 750 GB, OK) physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SATA, 750 GB, OK) array B (SATA, Unused Space: 0 MB) logicaldrive 2 (2.7 TB, RAID 5, Failed) physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SATA, 750 GB, OK) physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SATA, 750 GB, OK) physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SATA, 750 GB, OK) physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SATA, 750 GB, Failed) physicaldrive 2I:1:7 (port 2I:box 1:bay 7, SATA, 750 GB, OK) unassigned physicaldrive 2I:1:8 (port 2I:box 1:bay 8, SATA, 750 GB, OK) ~# I thought that I had drive 2I:1:8 configured as a spare for Array A and Array B, but it seems this was not the case :-(. I noticed the problem due to I/O errors on the host, even if only 1 physicaldrive of the RAID5 is failed. Does someone know why this could happen? The logicaldrive should go into "Degraded" mode but still be fully accessible from the host os!? I first tried to add the unassigned drive 2I:1:8 as a spare to logicaldrive 2, but this was not possible: ~# /usr/sbin/hpacucli ctrl slot=0 array B add spares=2I:1:8 Error: This operation is not supported with the current configuration. Use the "show" command on devices to show additional details about the configuration. ~# Interestingly it is possible to add the unassigned drive to the first array without problems. I thought maybe the controller put the array into "failed" state due to the missing spare and protects failed arrays from modification. So I tried was to reenable the logicaldrive (to add the spare afterwards): ~# /usr/sbin/hpacucli ctrl slot=0 ld 2 modify reenable Warning: Any previously existing data on the logical drive may not be valid or recoverable. Continue? (y/n) y Error: This operation is not supported with the current configuration. Use the "show" command on devices to show additional details about the configuration. ~# But as you can see, re-enabling the logicaldrive this was not possible. Now I replaced the failed drive by hotswapping it with the unassigned drive. The status now looks like this: ~# /usr/sbin/hpacucli ctrl slot=0 show config Smart Array P400 in Slot 0 (Embedded) (sn: XXXX) array A (SATA, Unused Space: 0 MB) logicaldrive 1 (698.6 GB, RAID 1, OK) physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SATA, 750 GB, OK) physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SATA, 750 GB, OK) array B (SATA, Unused Space: 0 MB) logicaldrive 2 (2.7 TB, RAID 5, Failed) physicaldrive 1I:1:3 (port 1I:box 1:bay 3, SATA, 750 GB, OK) physicaldrive 1I:1:4 (port 1I:box 1:bay 4, SATA, 750 GB, OK) physicaldrive 2I:1:5 (port 2I:box 1:bay 5, SATA, 750 GB, OK) physicaldrive 2I:1:6 (port 2I:box 1:bay 6, SATA, 750 GB, OK) physicaldrive 2I:1:7 (port 2I:box 1:bay 7, SATA, 750 GB, OK) ~# The logical drive is still not accessible. Why is it not rebuilding? What can I do? FYI, this is the configuration of my controller: ~# /usr/sbin/hpacucli ctrl slot=0 show Smart Array P400 in Slot 0 (Embedded) Bus Interface: PCI Slot: 0 Serial Number: XXXX Cache Serial Number: XXXX RAID 6 (ADG) Status: Enabled Controller Status: OK Chassis Slot: Hardware Revision: Rev E Firmware Version: 5.22 Rebuild Priority: Medium Expand Priority: Medium Surface Scan Delay: 15 secs Surface Analysis Inconsistency Notification: Disabled Raid1 Write Buffering: Disabled Post Prompt Timeout: 0 secs Cache Board Present: True Cache Status: OK Accelerator Ratio: 25% Read / 75% Write Drive Write Cache: Disabled Total Cache Size: 256 MB No-Battery Write Cache: Disabled Cache Backup Power Source: Batteries Battery/Capacitor Count: 1 Battery/Capacitor Status: OK SATA NCQ Supported: True ~# Thanks for you help in advance.

• hdparm - how to secure erase SATA SSD over USB

  - by cc0

  I have been following this guide on how to secure erase an SSD (trying to improve the performance of mine, which currently only writes at about 30mb/s seq). However, I'm using an USB--Sata docking device to avoid having the harddrive frozen. Apparently using this solution the SATA device is recognized as a SCSI drive, which is giving me trouble. I use the "hdparm -I /dev/sda" command with those parameters, and I get the error; HDIO_DRIVE_CMD (identify) failed: Invalid Exchange After a lot of googling on the issue I can't seem to find anyone who has actually solved this problem. However, I have not tried to just go ahead and use the secure erase. So I'm not sure if this would actually still work. I would love any and all input I can get on this, especially on whether it will still work to do a secure erase with the drive being recognized as a SCSI drive. The drive itself is a Samsung 256gb SSD (pm800), I'm sure you can understand my reluctance to go through this procedure without feeling reasonably safe that I won't mess it up beyond repair.

  This is my motherboard GA-M61PME-S2 (SATA upto 3.0 Gbps) and This is my Hard Disk Samsung hd502hi Capacity 500 GB Cache 16MB Disks / Heads 1 / 2 Interface SATA 3Gb/s Spindle Speed 5400 RPM Sustained Data Rate OD 100 MB/s Average Seek 8.9 ms Average Latency 5.56 ms Data Transfer Rate 300 MB/sec Weight 470 grams Power: Idle / Seek / R-W / Spin-up 3.9W / 4.8W / 5.1W / ~24W Acoustics (sound power) 2.2 / 2.7 Bel (idle / quiet seek / performance seek) When I copy things from one partition to another they transfer at a maximum of 30 MBps. However the drive supports upto 300 MBps right ? How do I increase the transfer speeds? P.S - Using Windows XP, All partitions are NTFS.

• RAID driver to choose for slipstreaming XP installation on ASUS P5S800

  - by alex

  I'm trying to install Windows XP on my new SATA drive but I need to first slipstream the drivers with nLite. I've done this before, but not on an ASUS P5S800 - VM motherboard. I'm not used to the number of choices it gives me for drivers in SiS chipsets. When I look through the folder that I downloaded from ASUS for the RAID driver, I see many folders with different versions of the driver. Here are the folders or versions given. 180ob 964_180 965 966_968 What drivers do I need to add in order to get XP on my SATA disk?

• Yet again: "This device can perform faster" (Samsung Galaxy Tab 2)

  - by Mike C

  I've been doing a lot of research with no reasonable solution. Please excuse the length of my post. When I plug my Galaxy Tab 2 (7" / Wi-Fi only / Android ICS) into my Windows 7 64-bit machine, I (almost always) get this warning popup that "This device can perform faster." And in fact, transfers onto the Tab in this mode are slow. The two times I've been able to get a high-speed connection, the transfer has occurred at the expected speed. I just don't know what to do to get that high-speed transfer. (The first time I did, it was the first time I connected the Tab; the second time I did, I was fiddling around and unplugging/plugging in again.) That popup is telling me that the device is USB2, but that it thinks I've connected to a USB1 port. In fact, every USB port (there are ten) on this system is USB2. It's an ASUS M3A78-EMH mobo from late 2008. I'm not sure what the chipset is; the CPU is an AMD Athlon 4850e, but I've seen this message reported for non-AMD systems. (Every mobo reference I've seen in reports on this has been for Asus, but of course most reporters aren't reporting that info at all.) The Windows 7 installation is just a couple weeks old (I had a disk crash) but I saw the same warning on the WinXP/64 that was installed previously. In Device Manager, there are two "Standard Enhanced PCI to USB Host Controller" nodes which are the actual high-speed controllers. There are also five "Standard OpenHCD USB Host Controller" nodes, which I have determined are virtual USB1 controllers embedded in the "Enhanced" controllers. (In Device Manager, I'm using View|Devices by Connection.) My high-speed thumb drives, external disks, and iPod all show up as subnodes of the "Enhanced" controllers; the keyboard, mouse, and USB speakers under the "OpenHCD" ones -- and this is true no matter which ports these devices are plugged into. The Tab shows up under an OpenHCD node, unsurprisingly. It appears as a threesome: a top-level "Mobile USB Composite device" with two subs: "Galaxy Tab 2" and "Mobile USB Modem." (I have no idea what the modem device implies or how I might use it, but I don't care about it either: I just want the Tab to reliably connect at high speed.) On the Tab, the USB support has a switch between PTP and MTP, the latter being the default, and the preferred mode for me (as I'm usually hooking it up for music synch). I have tried, however, connecting it as PTP, and it still connects as USB 1. (As PTP, only the "Galaxy Tab 2" device appears -- no Composite, no Modem.) If it's plugged in as MTP and I change the setting to PTP, Windows unloads and reloads the device, and voila: The Tab appears under an "Enhanced" node, but eventually re-loads again to show a exclamation icon on the device; Properties then shows "This device cannot start." Same response if I plug it in as PTP and then change to MTP; in this case, only the Tab itself shows the exclamation, not the other two devices. One thing I have not tried, and really would prefer to avoid, is installing the "beta" chipset driver available on the Asus website, which is dated 2009. Windows tells me it has the most up-to-date drivers for the Tab, and for the chipset, and I'm inclined to believe that. I suspect the problem is with the Samsung drivers, or possibly the hardware. One suggestion I saw elsewhere which might, possibly, pertain is to ensure the USB cable is properly shielded; however, the Tab has one of those misbegotten 30-pin, not-quite-an-iPod connectors; I don't know if I could find a 3rd party one. It seems unlikely that this cable is improperly shielded, tho. (Is there a way to test that?) So, my question is: does anyone know how to get this working as one might reasonably expect it to?
