  • usb flash drives how to fix ?

    - by madyotto
    Hi all I have recently purchased some so called 256gb Kingston drives that are fake I used a program called check flash and few other to check for dead sectors and read speed and read and write speed the results are as follows: they were reading at 1.35 mbps at best they read and wrote at 0.95 mbps and had a hell of a lot of dead sectors so what I ask is: Is there a way to drop the size to improve speed Is there any other way to improve speed How can I stop the device from addressing the dead sectors Any help will be much appreciated ALL THE THANKS (MADYOTTO)

  • Hard disk failure. Can I recover my "move"d folders?

    - by Doug
    I am in the process of moving all my files from an old laptop to new one. I just moved 11gb of data from my old laptop to a hard drive (external) and then upon moving it out to the new hard drive, the hard drive is getting a CRC (Data Error (Cyclic Redundancy Check). Now I am looking for a solution to recover the files that I moved on my old laptop (not the external). I understand they they are just marked for potential overwriting to free up space. I was getting ready to test out GetDataBack, but it says to install it on a healthy windows and use the recover-needed drive as an external. However, I don't want to turn off my computer without first getting the okay since it is in a "moved" state. Please help! What can I do to recover the Moved files. I haven't touched the computer since it has been moved. What can I use to recover them?

  • Do not get 'Safely remove' option in Tray for USB storage devices.

    - by blitzkriegz
    I had done some tweaks in service settings (Disabled some as I thought it is not needed). Now, I am not getting the option to safely remove mass storage device when I click the icon on the system tray. I tried enabling some of the services, but it didn't help. Moreover I'm not very sure if this anomaly is because of my changes in services. Any idea how to make those 'safely remove' options appear when I click the USB icon on the tray. Right now nothing is happening when I click.

  • How can I find which logon script is being run?

    - by user2517266
    I'm having an issue with network drives. Suddenly some computers and users aren't getting their mapped network drives from the logon script. I am NOT a domain admin, I don't have permission to login to the domain controller. And I know very little about Active Directory. The issue seems random, some users this day, different users tomorrow. Some computers run fine and some won't map no matter who logs in. They are mixed OS's XP (SP3), Vista, and 7. I was looking at the domain in windows explorer and I have found the batch file(s) that maps the drives in several locations, how do I know which one is actually being ran? The .bat file is located in \DOMAIN\NETLOGON\script.bat and \DOMAIN\SYSVOL\DOMAIN\scripts\script.bat and \DOMAIN\SYSVOL\DOMAIN\policies\GUID(Right? It's a crazy string)\User\Scripts\Logon\script.bat So, how can I figure out which one is actually being ran per computer or user? Cause they are all slightly different from each other and one of them doesn't map properly. Do all the files in NETLOGON get ran? Cause there are 15+ files in there. Or is it specified in Group Policy which one(s) get ran? EDIT: I am able to access a program called Active Directory Users and Computers, but the properties tab for any user is blank for the logon script.

  • How to fix a Corrupted USB

    - by Help
    My USB stick has suddenly stopped working. It's a Busbi 4GB. My USB used to be G:/ but as soon as I plugged it in, I used to get a pop up box showing that it was plugged in. Now, when I plug this in, it shows as I:/ and no pop up box appears. It shows in my computer as I:/ and when I click to open it says I:/ is not accessible the disk structure is corrupted and unreadable. I have tried to change the file name back to G:/ but nothing happened (this was under disk management). On disk management, it shows Volume as I:/ Layout simple Type Basic File system RAW status Healthy (Active,Primary partition) Capacity 3.42GB. I've tried right clicking properties then the tab tools and click error checking (this option will check the volume for errors). When I click "check now" it comes up with the disk check could not be performed because Windows cannot access the disk.

  • In Linux, is there a way to get a warning if I forget to unplug my pendrive?

    - by missingno
    I forgot my pendrive plugged in when leaving the computer lab yesterday, and I would have lost it if it wasn't for a kind soul finding and returning it. I want to avoid this in the future and apparently there are some tools you can use in windows that warn you if you are leaving a pendrive behind when logging off or shutting down the computer. Is there anything similar that works on Linux? I need this to work on Fedora 17 (GNOME 3 shell), and preferably without requiring administrator privileges.

  • Is it possible to populate HTML form field data in an iPhone UIWebView using external accessory fram

    - by Jon Smallberries
    I have an iPhone app where I'd like to load a remotely served HTML form into a UIWebView and then populate that form as data becomes available from an external accessory using the "External Accessory Framework." Right now the data is entered by hand. The proposed flow is: Fetch an HTML page containing a form and put it into a UIWebView When data becomes available from the external accessory, populate the form field(s) Submit the form Is it possible to do this by "injecting" data from the external accessory into the UIWebView when all required data has been retrieved from the external accessory? I cannot seem to find any good examples on how to use the external accessory framework to achieve this.

  • Making(programming) virtual drives on windows XP

    - by Manux
    Ahoy, I'd like to mount a "virtual drive" myself on Windows XP, I guess using the windows API. What I thought about would be like a server interface, meaning explorer.exe would send "queries", like, list directory, or get file through a pipe or whatever... I know some programs do it, maybe not the way I think it is done, but what the heck, if you know anything, enlighten me please!

  • Searching for SD-cards

    - by Shaddix
    I need to implement searching for SD-cards in my program. Currently I'm using search for all removable devices like: searcher = New Management.ManagementObjectSearcher("\\localhost\root\cimv2", "SELECT DeviceId FROM Win32_LogicalDisk WHERE DriveType=2 AND Size>0"); But it find USB flash drives also. Is there a proper way to find SD-cards only? What I need is in general only drive letter for available SD-cards (like "F:" or so).

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

    - by TegtmeierDE
    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.

  • Dock with dual external DVI monitors with Intel + Nvidia Optimus?

    - by Ryan
    I have a Dell Latitude E6420 laptop plugged into a docking station, and the dock has 2 monitors (connected with DVI). Also note that I've installed Ubuntu alongside (dual-boot) Windows 7. I can't get the dual monitors to work both on Ubuntu (either 11.10 or 12.04) and Windows 7. When I run lspci | grep VGA, I get: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: nVidia Corporation GF108 [Quadro NVS 4200M] (rev a1) If I then reboot and uncheck Optimus setting in the BIOS during reboot, I'm able to get the dual monitors to work in Ubuntu 12.04 (but I need to configure them every boot in Nvidia Settings). When I run lspci | grep VGA, I get: 01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [Quadro NVS 4200M] (rev a1) But then if I reboot into Windows (leaving the Optimus unchecked), Windows can't detect external monitors, and the resolution is unacceptably low. I've seen on many forum posts that this particular graphics card setup causes lots of headaches. I haven't been able to resolve my problem yet. How can I use my external display on my laptop with intel and nvidia video cards? How to use external displays with Intel driver on a NVidia/Intel hybrid system nVidia Optimus , Unity 3D and Dual Monitors "Just use VGA instead of DVI" isn't an option because my dock has only 1 VGA port (and 2 DVI). Switching the BIOS setting on every reboot and then reconfiguring the display settings every time is tedious, time-consuming, and impractical. Do you know how to make this work smoothly? Thanks for your help! P.S. see also: http://superuser.com/questions/434358/dell-latitude-e6420-dual-boot-ubuntu-windows-7-optimus-graphics-problems

  • Can T520+Bumblebee run an external monitor via DisplayPort?

    - by Fen
    Using 64-bit Ubuntu 11.10 and integrated (Intel) graphics, I can run the 1600x900 laptop display plus a 1600x1200 external monitor connected to the VGA adapter. But my external monitor is 1920x1200 so I have black stripes on each side. I believe the resolution is limited like this as the maximum resolution available from the Intel GPU is 2560x1600 = 4,096,000 pixels and I'm asking for a 3520x1200 = 4,224,000 display (with 1200x300 lost above the laptop screen). At 3200x1200 = 3,840,000 pixels, the Intel GPU seems happy. Under Windows, the same limit exists when using the VGA adapter, but if I turn Optimus on then I can connect the external monitor to the DisplayPort and get its full resolution and an extended desktop. I've seen that Bumblebee can run apps on the DisplayPort using the 'optirun' command. My question is: can Bumblebee run the DisplayPort in concert with the Intel card running the laptop screen creating a large virtual desktop (as on Windows)? If so, are there any pointers to how to do this? I tried once, failed, and dropped back to Integrated Graphics (and black stripes) as I could find no reports of this configuration working.

  • Why am I getting [mount error(22): Invalid argument] while trying to mount SMB network drive?

    - by Steve_
    Disclaimer: I am very new to Linux :) Anyway, onward: I have a fresh instance of Ubuntu Server (12.04.1 LTS) running on my network and I want to mount a network drive to the server so I can access the contents. The network drive is a SAMBA compatible drive running Darwin OS. If I run the following command: smbclient -L //192.168.0.2 -U myuser It prompts me for the password and then displays output similar to: Domain=[SERVER01] OS=[Darwin] Server=[@(#)PROGRAM:smbd PROJECT:smbx-105.4.0] Sharename Type Comment --------- ---- ------- Comp Staff's Public Folder Disk CompRaid03 Disk Dropbox Disk Groups Disk IPC$ IPC Public Disk Users Disk compstaff Disk However, when I try and mount the CompRaid03 share, using this command: sudo mount -t cifs //192.168.0.2/CompRaid03 /mnt/myshare -o username=myuser I get the same password prompt, but after putting the correct password in, I received this error: mount error(22): Invalid argument dmesg | tail returns: [23576.037373] CIFS VFS: cifs_mount failed w/return code = -22 I don't understand what is wrong with this command. I've managed to mount a share on my current (Windows 8) machine using basically the same command but with a different IP address and share name (obviously). I've spent a good few hours trying to solve this and got no where. Any help or pointers would be greatly appreciated. Thanks Steve EDIT As suggested I've also trued using "user=" instead of "username=": sudo mount -t cifs //192.168.0.2/CompRaid03 /mnt/svnrepo -o user=myuser This results in the same "Invalid argument" error.

    - by Adrian
    I`m currently working on a script, and I have the following situation. function somnicefunction() { require 'someexternalclass.php'; $somevar = new SomeExternalClass(); } For some reason, the above breaks the function. I'm not sure why, I haven't seen much documentation in php.net regarding this, plus google returned no real results. Does anyone have any idea ?

  • manipulate objects outside svg with javascript-function inside the svg

    - by Christian Benke
    Hello! I'm embedding a svg-graphic on my website and i'd like to manipulate the rest of the website with javascript-commands which are in the svg - though i'm not sure if this is possible. Let me elaborate: I've got a worldmap in svg, i want to click on a country and this click should run an ajax-call and load relevant information of this country into a div in the html site where the svg is embedded. "onclick="location.href='xxx'"" redirects to the respective site which is fine, but i'd prefer to run a js-function that fetches the site with ajax - but running a javascript-function in the svg only seems to work for functions and elements defined in the svg, not outside of it. Is it basically possible to manipulate anything outside the svg through a js-function in the svg? How? Regards Christian
