After plugging in a memory stick, the laptop can take up to 2 minutes to discover and show up in explorer. I have tried 3 different makes of stick so far, Transcend, Kingston &amp; Corsair. All are USB 2.0 compliant. All work fine in various other boxes. All of them contain nothing but data (MS docs, pdfs, images &amp; text files). No autoruns, clever encryption or utilities. All are eventually discovered and usable.  Laptop is an ASUS X71Q running Windows 7 32-bit Home Premium, 3GB of RAM. (Out of warranty) Norton Internet Security is installed, however, with it temporarily disabled I still get the delay.  I am not asking about data transfer rates. There is no problem with USB mice or keyboards. This happens at any time, not just straight after booting. There is no "installing device drivers" message. I have removed or stopped all ASUS bloatware/utilities. It happens on all USB ports. USB drivers are from MS (recommended by ASUS) and have been removed/reinstalled. It makes no difference if it is running on battery or adapter. It also happens in safe mode. Memory usage is sat at 1-1.25GB before I plug in the stick and doesn't change after. Disk cache increases by 6MB when the stick is recognised and drops back down when it's removed. None of the sticks are readyboost compliant. Defrag of the HDD has made no difference. There is no delay when using a Kubuntu LiveCD

I reattach dozens of USB devices to my Windows 7 across the day, such as printers, flash drives, mice, modems, midi keyboards, and scanners. The computer has seen them all before; all have been set up previously.    Yet in most cases, Windows takes 20-60 seconds to finish initialising the device and get it ready for use. Is there a way via software to cut this time short?

I have a SanDisk Cruzer 32gb flash drive that cannot be read only on a specific computer due to some unknown reason. Do note that all my other flash drives are working fine on this computer. Here's my situation... Background Info I recently bought a HP laptop. Before wiping the laptop's hard disk, I used HP recovery media creator to store the HP recovery image in my flash drive. After I was done with wiping my laptop's hard disk and making sure my clean installation of the operating system works, I wiped my flash drive with the standard Windows formatting utility. I don't like the OEM's recovery stuffs because of all the bloatware, but I backed it up to my flash drive just in case my clean installation fails. The Problem Now, this flash drive cannot be read on my main desktop (running Windows 8) anymore. However, the same flash drive can be read on my other two computers (also running Windows 8) perfectly fine. Observations:  The flash drive cannot be accessed in Windows Explorer or any Explorer alternatives. Received &quot;Windows can't access this disk&quot; error messages when trying to check the disk's filesystem. The flash drive's size cannot be viewed in My Computer.  Ironically, according to the Device Manager, the USB flash drive is detected and working fine. Things I've Tried  Uninstalling the USB mass storage driver and rebooting. Uninstalling all USB drivers and rebooting. Wiping and reformatting my flash drive on the computers that it can work on using MiniTool Partition Wizard. Using BootIce to rewrite the MBR of the flash drive. Copying the MBR of my other flash drives to the problem flash drive using BootIce. I've also tried formatting in FAT16, FAT32 and NTFS.  All of the above methods have failed. Does anyone know what's the problem, or have encountered such errors before? Please enlighten me. Your help is much appreciated. Thank you. =)

So from what I've read online, if AHCI is enabled in the BIOS, I should be able to hot-swap a SATA drive and it will supposedly "just work".  However, that has not been my experience.  When I hot-swap a SATA drive on my system, it is never detected. It doesn't show up in lsblk, it doesn't show up in Gparted, nothing even shows in dmesg.  So, I am wondering what the issue is?  I am using 16.04 on an Asus M5A97 R2.0    Edit to address Takkat's suggestion:  I have no such option:

Windows asks me to reformat every time I plug it into my computer, so I fired up Ubuntu via VirtualBox (selecting the external hard drive in the USB settings for VirtualBox beforehand) to see if I can access it there.  Does anyone have any suggestions for me? I have over 1TB of data on this drive and do not want to lose it. When I plug it into an electrical outlet, the light turns on, and when I plug it into my laptop, I can feel it clicking.

I have a really strange situation here. My PC works fine, at least in most cases, but there's one thing that I can't deal with. When I try to copy a file from my pendrive, everything is ok -- I got 16-19M/s , it works pretty well. But when I try to copy something to the same pendrive, my PC freezes. The mouse pointer stops moving for a sec or two, then it moves a little bit and it stops again. When something is playing, for example, in Amarok, the sound acts like a machine gun. The speed jumps from 500K/s to 15M/s, average 8M/s. This occurs only when I'm copying something to a pendrive. When the process of copying is done, everything backs to normal.   I tried everything -- other pendrive, a different USB port on front panel or those ports from back, I even changed the USB pins on motherboard (front panel), but no matter where I put my USB stick, it's always the same. I tried different filesystem -- fat32, ext4. I have no problem with the device on Windows, on my laptop. It has to be my PC or something in my system. I have no idea what to look for. I'm using Debian testing with standalone Openbox. My PC is kind of old -- Pentium D 3GHz, 1GiB of RAM, 1,5TB WD Green disk. If you have something that would help me to solve this issue, I'd be glad to hear that.  I don't know what else info I should provide, but if you need something, just ask, I'll update this post as soon as possible.  I tried to reproduce this problem on ubuntu 13.04 live cd. I mounted my encrypted partition + encrypted swap and connected my pendrive to a usb port. Next I tried to start some apps, and now I have ~820MiB in RAM and about 400MiB in SWAP. There's no problem with copying, no freezing at all, everything is as it should be. So, it looks like it's a fault of the system, but where exactly? What would cause such a weird behavior?

I work at an embedded software company. This morning I found a USB stick in the parking lot in front of the building. With all the stories of "dropped USB stick attacks" in mind, I'm obviously not going to just plug it into my laptop. OTOH, I'm curious to know whether this was actually an attempt to compromise our systems, or it's really just an innocent case of somebody accidentally losing a USB stick. How do I safely inspect the USB stick without risking exposure?  I'm worried not just about malware and crafted file system images; there's also stuff like power surge attacks:.  EDIT: Many of the answers seem to assume I want to keep the drive and use it afterwards. I have no interest in that at all, I know USB sticks are cheap, and that it wouldn't be mine to keep anyway. I only want to know whether this was indeed a semi-targeted attack, partly out of curiosity whether this actually happens in real life and not just in security papers, but also so that I could warn my coworkers.  I want to know how I would figure out whether the stick contains malware. And that's not just a matter of looking at the drive contents and seeing a suspicious autorun.inf or a carefully crafted corrupt file system - I very much also want a way to inspect the firmware. I sort-of expected that there were tools for extracting that and comparing to known-good or known-bad binaries.

I already tried FORMAT /FS:FAT, , Disk Management and .   Do I really need to buy a smaller capacity drive? Can't a formatting tool ignore the area beyond 2&nbsp;GB?  My Asus netbook's BIOS update requires the USB to be formatted as , and I couldn't get the various Asus BIOS update utilities to work.

A person has a computer with no HDD but 16GB RAM and USB3 port.  Also has 16GB USB3 pendrive with Ubuntu Live on it, (Non persistent).  The computer is then started with the pendrive using toram.  The pendrive is then removed and reinserted while the O/S is running.  Is the O/S that is running in RAM able to do a "Full" install to the pendrive?  This was asked in:     However for some reason this unique question was marked as "Duplicate".

Since I upgraded to Windows 10, my system has been consuming RAM excessively    I've been reading a bit and determined it's likely a driver leaking memory. So I got myself the Windows Driver Kit and tracked memory usage with poolmon:    However, I don't really know how to proceed from here. Is the item tagged "smNp" the culprit in this issue? How do I go from there to actually identifying the driver?  I tried some stuff like "C:\Windows\System32\drivers>findstr /s smnp ." but it returned no results. I also took a look at the pooltag.txt file and this is the description I found for it:      So yeah, any help would be appreciated. Thanks in advance.

OS: Win7 Pro x64 Laptop: Lenovo x240 Dock: Lenovo ThinkPad Basic Dock - Port Replicator  Monitor 1: AOC 21.5", E2243FW (VGA) Monitor 2: Lenovo 21.5", LS2223 (DVI)   Issue:  When hovering the cursor over any pinned/unpinned icon on my taskbar, the preview icon that pops up is quickly fading away (as quickly as it starts up, seemingly with the reverse animation as when it appears).  While holding Alt and pressing Tab to cycle through open applications, the window of icons will disappear (and if I continue to hold Alt and press Tab again, the window will reappear and will start me back at the first icon).  This problem will "randomly" not happen after rebooting and then will begin happening again.  Attempts to resolve:   Fully run the Windows and ThinkVantage System Updates Removed all unnecessary peripherals (keyboard, external CD drive, ect) Changed Visual Effects from "Let Windows choose what's best for my computer" to "Adjust for best performance", as well as Custom (all unchecked, and tried solely checking "Save taskbar thumbnail previews") Used one monitor at a time (tried both monitors separately). Lowered the resolution and refresh rate of each monitor. Removed all external monitors. Used the laptop completely removed from the dock and external peripherals Safemode   Comments:  I have seen some  that can extend  which, as you can imagine, I'm hoping to steer clear of having to make any changes like this. No other Windows 7 machines I've used have had this issue.  My guess is that an application isn't stealing Window's focus since I'm able to leave the Start menu up for an infinite amount of time without it minimizing.  Edit: I notice the amount of time icon previews stay visible varies - they could last 3 seconds, 5 seconds, 10 second, half a second, ect.

so as I say in the title I have this very big, annoying problem. On my new PC (HP Omen 2020, i7-10750h, Nvidia RTX 2070, 16GB RAM) when I connect an external hard drive (precisely an WD My Passport Ultra, 3TB) I get occasionally mouse and keyboard freezes. Practically, the system becomes unusable. The mouse and keyboards works, they even show in device manager, but from time to time (too often) they &quot;freezes&quot;: mouse pointer freeze, and it won't respond to my input, and keyboard too, if I type something it will not respond. First I thought this was a behaviour due to bad drivers, or something related to my new PC, the fact that it has USB 3.1 ports. But then I've noticed that this fact happens only when I connect my WD Hard Disk (which is USB 3.0) to my pc. I've tried some stuff online, suggesting to update drivers, change some windows settings, but with no success. My guess is that the hard disk and the mouse-keyboard does interfere with each other in some ways. I guess that it's a software problem, at driver levels maybe, not a physical one. When the mouse doesn't respond, I've tried to use the touchpad on the notebook, and it does work. So it's not a windows freeze, it's just the device (mouse-keyboard-receiver) that doesn't respond. The mouse and keyboard are from Logitech, bot connected with the Unifiying receiver (a wireless receiver they provide for the mouse and the keyboard). Model: MX Anywhere 2S for the mouse, K360 for the keyboard. Please, help me solve this problem, monday I start taking my engineering class lessons from MS Teams, and I need my pc up and running and well responsive (I need to access data from the hard disk while I take classes). PS: I've seen that there are some other questions like this in the forum, but none of them seems to provide a solution to the problem. I would also change the external hard drive in the future, but I need to know that the problem with this one won't show with another hard drive, or other devices. I've already sent this very same post to Microsoft community, I really need help with this thing otherwise it will be a problem following my online classes. Thank you if you will try to help me EDIT: On the notebook in question I have 4 USB 3.1 Ports, with two ports on each side, and a single Type-C Thunderbolt port (I'm not counting that one cause both the hard disk and the logitech receiver are USB 3.0 type A connectors). I've already tried switching USB port, connecting the WD Hard Disk to another port, doing the same on the logitech receiver, and I've even tried putting them one on the left side and the other to the right side, to minimize &quot;interference&quot; as someone suggested. But nothing, I still got this problem, which seems driver-related. Hope this will give more info

After purchasing a Lenovo Ideapad Flex 2 14, I tried to upgrade it and replaced the HDD with an SSD from my older laptop. After putting in the SSD, I encountered a numerous amount of problems.  First, the Windows installation program didn't see the SSD, even the Diskpart utility didn't see it, so I decided to install Ubuntu instead, which was installed successfully. Everything was fine, but after messing around with the BIOS, the laptop wouldn't load the OS unless I first went into BIOS and exited it.  Windows still never saw the SSD, even after I installed Ubuntu on it and then tried to install Windows again. What could be the problem? Also, the HDD that came with this laptop works just fine, and the SSD works in another laptop just fine, too. The SSD is Intel 335 series 240GB. I'm gonna try to install Windows 7 a little later and see if that will work, but other than that I've already wasted an entire day trying to figure it out.

In a nutshell, the problem looks like this picture:    In short, gigantic latency, very slow read speed (I assume that is caused by the same thing). After a very very painful few minutes, everything seems to go back to normal.  What the heck is going on that can cause that?  Note: Note the fact that 100% activity happens at a wide range of speeds.

I have upgraded my computer using a core i5 2500K from Windows 7 x64 to WIndows 10 x64, and the whole system runs fast and reliable, with one exception: after booting from SSD, which takes only about 10 seconds, my keyboard is really slow for the first 1 or 2 minutes right after booting. "Slow" means that when I start notepad, and type some characters, it takes a second for each character to appear on screen. Everything else is fast, including mouse movement, starting programs, only keyboard input is that slow. After 1 to 2 minutes, the keyboard suddenly behaves normally again.  This happens with every kind of keyboard I connect, no matter if I use the legacy PS/2 adapter, or USB.  Does anybody have any idea what might be the cause of this strange behaviour?

When I was installing Ubuntu 11.10 64-bit on my new PC from a flash drive since the only computers I have do not have disk drives, I ran into a problem.  After the ASUS logo when switching on the PC, and pressing F8 to select the USB flash drive, there was the options thing as normal that allows me to select to either boot form the flash drive or install on the HDD, when I do either of these, there is a bunch of text on a black background, as I would expect, but after a few seconds the screen goes blank and the monitor says No signal.  I have previously installed Ubuntu with a flash drive to fix issues caused my Windows and ran into no problems.  Is it a problem with the pen drive I am using? Or maybe a problem with the system? I tried it in my USB 3.0 ports at the back and the USB 2.0 ones as well.  My Specs are:   &nbsp;&nbsp;AMD Phenom II x4 965BE &nbsp;&nbsp;ASUS AMD Radeon HD 6670 &nbsp;&nbsp;ASUS M5-L75 USB3 (typing this from memory, it's an AM3+ ASUS board with USB3.0 in the AMD700 chipet or something) &nbsp;&nbsp;Corsair XMS3 DDR3 4GB(2x2GB) 1333MHz RAM    I ran the memtest program on the flash drive as well, and it came out clean.

I have a Sony VAIO laptop (VGN-SZ1HP/B) that unfortunately has only one memory slot working (see my previous problem ), and it's very annoying as I'm limited to 1GB of RAM. According to Crucial, my machine has a , but obviously I'm stuck with 1GB... as only one slot is working.    I was wondering... would it be possible to install a single 2GB stick into the one slot that is working? That would not exceed the maximum allowed by the machine, afterall.  Is there a chance it could work? Thanks for any advice.
