Flash Drive Periodically Does Not Show In My Computer
Jun 14, 2012
I have an issue where my flash drive periodically won't show up in My Computer... when I insert it, I hear the 'hardware insert' sound but no drive in my computer and no autostart. it doesn't show in device manager and clicking 'refresh' does not make it show up! if I remove the flash drive, the drive appears in 'my computer' for a second then disappears... the same problem occurs when I plug it into another port... I have four ports, only three of them are not used by something plugged in permanently... usually I have to insert the flash drive into random ports at least 5 times before it displays the drive...
For awhile now my mouse has been very erratic, and I want to reinstall my comp to rid the problem. My antivirus & Malwarebytes' are not finding the problem.
With all my files now on a flash drive, is it possible to re-contract whatever is giving me mouse problems when I stick the drive back in a fresh installed comp? I highly doubt it, but I want another person's opinion.
I have a 8 GB Transcend flash drive. I works properly on other systems (at least one system), but when I plug it in my Laptop, it is not even detected. Other USB devices work perfectly with my laptop, the only problem is with my Flash drive AND my laptop. I have tried to re install USB Hubs etc. of the laptop, but it did not help.
I am using Windows 7 64 bit Home Edition. Is it appropriate to use chkdsk periodically to check the health of my C: & D: file systems? Can running chkdsk cause any harm to the file system?
How can you copy one flash drive to another flash drive,on the same computer?

Ever since I've had this laptop I've had some periodic blue screens. I've never been able to pin down exactly what the causes are, as they seem to be a variety of things. I really hope I don't have to reinstall Windows because this laptop did not come with the disk
My internet connection keeps dropping periodically.I get the below dialog box and on clicking 'redial' it connects again but again i get the same dialog box in 10-15 minutes.I use windows 7.Tbh i have 0 knowledge of all this LAN related things so i am attaching screenshots of various details of my PC.Please let me know if you need any more details.[Here on right clicking 'Local Are connection 2'->properties->configure->Advanced Tab the setting there are:
Flow control - Disabled InterruptModeration - Enabled Network address - Not present Receive Buffers - 160 Speed and Duplex settings-Auto negotiation Transmit buffers-160 ]
i've got 4 gb of ram, and using windows 7 64bit. my normal day to day memory usage is usually 1.2gb-1.8gb, that's using firefox, chrome etc... however recently i've started getting these events where for a couple of minutes at a time (sometimes until i close a particular program), my system will be using every single available piece of memory. not only does my memory usage reach 100%, my other programs (firefox, chrome, skype etc...) that are open start getting 'squeezed' out; i'm guessing they are getting relocated to the stack. for example, usually my firefox is running on about 150-400mb of memory. during these incidents and for some time after it gets squashed to 18mb, with the same number of tabs open etc... when the event ends, memory usage drops down to 900mb in one instant. what's also interesting is that my cpu usage drops down while this is happening, in fact during these periods it's quite lower than usual (usage doesn't seem to go above 10%).i've tried finding out what this is, however on task manager and resource monitor, there is no program that is using that much memory. basically, on the performance tab, it's telling me i'm using 3.9gb of memory, on the processes tab the sum of the memory used by all the programs there can't be more than 500mb (in fact during these fits the total goes down as the programs gets squashed out). so from that, at least from what i know, i'm guessing either it's a virus (i hope not and doubt it, i don't dl random stuff and i got kaspersky iss), or it's my windows 7 os which doesn't show up on processes. so i was wondering, is it possible that this is windows 7? i've never heard of this kind of bug, and i haven't been messing with setting recently, but i can't think what else it could be.also: i've noticed that these events can sometimes get triggered by particular events. for example, so far, everytime i've opened divx, this has happened, and it also lasted exactly until i closed divx; however it's not exclusively linked to divx. it happened once when i was just watching Internet, and another time when i was searching my disk for a particular file.
I am running Windows 7 Home Premium on Acer Ferrari 200 (pre-installed). There will always be times where after waking the notebook from sleep, the password will not get recognised. I am very sure password is correct. The occurance after a number of sleeps and wakes varies. And the only way to get in again is to hard reset. My account is admin privilege and the only account in the notebook. I have checked the security event log but there is not denied messages.
I have the latest Zonealarm Extreme 9 installed and Bit Defender disabled. All recommended Windows 7 patches installed.
my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so. Is the monitor responsible for the restart and what could be the reason for the flickering?
Before I even go further: yes, the "hide empty drives" has been unchecked)I had to reinstall my machine and I was able to to see the drive letters for the internal flash card reader. However I think something might have gone wrong when I give my external HDD a drive letter that was held by one of the flash card reader).I wrote "I think" because I am not really sure since I never wanted to use the internal card reader till today so I never noticed there was an issue. Anyway, the internal card reader does not show up even when I insert a card in the reader. Basically nothing happens. I have uninstalled the "USB Mass storage device" and it gets installed without any issue but the problem is still there: I can't see the reader. the INTERNAL flash card reader has a USB slot and when I insert a EXTERNAL flash drive, the EXTERNAL flash drive shows up.
I know, should have a backup, I was actually about to create a backup when the flash drive failed on me unfortunately. My newest backup is from about 5 days ago, so I'd prefer to be able to restore the current files.
I moved the drive over to another computer and tried to save a file but when I checked again the file was gone, like it never saved at all. Subsequently, after removing and plugging it back in the computer did not detect the drive (or see it in disc management). It does show up as a generic USB drive in the device manager, but there are no properties for it.
When I add it to a computer, it still adds drivers for it, but then nothing happens after that. It may also be a hardware problem, since the drive fell on the ground pretty hard a while back, but seemed to be working fine. There isn't an easy way to open it up and check.
I also tried using a few data recovery programs, but they couldn't detect the drive either.
I have a hard drive I want to backup to a 64gb flash drive and then restore it to another different hard drive than where it came from. I have windows 7 and office on my laptop and I want it on my desktop pc. There isn't close to 64gb of info on my laptop so it should be fine even though the hard drive says I have 160gb. It is all free space except for those programs.
So the drives in question are 3 Seagate 1.5tb 7200.11 HD's.
They show up fine in the BIOS where they are all listed as slaves (ga-p55-ud4p) and in Device Manager - which lists them all as working properly. I cannot distinguish one from another in Device Manager, and the one that is working has very important legal files on it.
However, I can only see one in "My Computer" - but the other 2 I cannot "see" them so I cannot access them.
The one I can see is the oldest one and was not altered when the older PC was upgraded (upgraded all components except HD's and OS). I also kept 2 older WD 500AAKS which are both working fine as well.
The two I cannot see: One is brand new. The other was reformatted to blank (quick) on another PC (which was upgraded to Win7 at that time) which subsequently could not see the drive. I moved it over to this faster PC and still cannot see it.
All these 1.5tb Seagate drives are CC firmware so are not part of the older firmware issue. None have any 1.5gb jumpers on them.
Mobo drivers are all fully up to date - I just re-updated all of them. Windows is up to date. Windows does show in the Troubleshooter that a USB controller driver is not found and I cannot seem to find out how to install it (via uninstalling it, updating drivers, etc etc - question thread
New external HDD won't show in "Computer". I Have searched a lot, but only find comments directing me to Disk management and Device manager. The Ext. HD is not showing there either. Power light is on. This is a Lacie 2 TB Minimus USB 3.0 External Hard Drive [URL] No "Doorbell" sound when I plug in or un plug the USB connector. The LaC i.e., troubleshooting page tells me to go to device manager, but like l said, it's not showing there either.
Plus, it seems to have knocked out several of my USB ports, and I had the warning flag next to several of them in device manager ,but I was able to get them back by right clicking on each line one at a time, Un installing, and right clicking on the heading for the group, and selected "scan for hardware change". Then in the tray, I saw Driver was installed, or device is ready, something like that. All the ports seem to be working now, and the yellow flags are gone.
I did then try the External drive again, but it is still not working. I also installed desktop manager, but it's telling me to plug in my external drive, and then to re start my device. And if I start Desktop Manager it says, "No LaCie Desktop compliant device found." So I have another computer that shares this monitor,so I shut this one down, and hooked up my usb keyboard and mouse to the other older desktop system running XP, and the older computer does recognize this external hard drive.
It is in My computer on the older XP system/computer. So I shut that one down and started this one, and it does not show up on this computer, but then I noticed my keyboard would not work. Had to switch the keyboard USB ports to the other front USB port. And I had the yellow flags back in device manager again. Had to un-install again and let the system re install (selecting "scan for hardware change). Windows 7 Home premium, 64 Bit, Compaq Desktop, model 2010.
I have just bought a used copy of Age of Empires 3, but when I put the Cd in my disk drive, nothing happens and I get no messages of any sort. I have A windows 7 laptop in good working order, and with the requirements to play the game. Can any one tell me if a game disk can become damaged enough that it won't play, or is there some other problem?
After install windows 7 everything fine until I install all Asus driver Intel chip all my HDD DVD is missing not show up on my computer anyone having problem? In bios it show up all HHD DVD ROM.
I want to transfer files from my ipod to my computer but when I look for my ipod in "my computer" it doesn't show as a drive. I can use it with I tunes, it works fine but for my purposes, I need to access the files on the drive in "my computer" I am using windows 7
I have just gotten a new and very powerful computer for Christmas, but the disk drive doesn't appear on the My Computer menu. I have checked the bios, and it is there, but Windows 7 doesn't seem to find it. I have Windows 7 64 bit and a Gigabyte 870A-UD3 motherboard.
I have a pen drive having 4gb of data. After I plugged in that pen drive in one PC the datas are not showing. Kindly advice how can I recover the data. I also try to see hidden folders option but after that it also not showing. In properties it is showing 4gb of data in use.
I recently ran into a very weird windows 7 bit problem after installing it on my desktop. I cannot copy large files/ holders into usb flash drive or write large files to cd/ dvd. The copying/ moving process would stay on for about 5-10 seconds then freezes then I get an error message. That is:
H: refers to a location that is unavailable. it could be on a hard drive on this computer...
I have all the latest drivers.
And windows/ nero 9 can't use my dvd drive to burn files.
Some info about my system: AMD X4 630 CPU. MSI KA780G (AMD 780G chipset) mobo. I have 2 sata hdds, non raid mode. The DVD drive is IDE. 4gb ram ddr2 ram. windows 7 64 bit.
My External USB Hard Drive doesn't show up in My Computer Win 7 64bit.
I've just received my Western Element 2,5Tb today. When I first plugged it in, it worked normally. But due to my over-excitement, I copied too much files at the same time and it wasn't working anymore. I regretted doing this immediately.
I have searched on the internet to find some solutions but all of them didn't work. I've checked the Computer Management, Disk Management, but nothing about my External HD showed up. In the notification area, my laptop still detected it and I can removed it properly [even though i can't use it at all].
I tried to connect to my USB and another Samsung 500Gb HDD. And it worked perfectly fine. Then, I tried to connect my new HDD to my sister's lap [she is using Window Vista] and it worked perfectly fine too.
Such as a mouse, a mobile, or an external drive.I mean make them visible (in My Computer) even though they're not connected so it's easier to remember what devices I use. My memory is awful, don't ask.Obviously I know I wouldn't be able to access the files unless the devices were connected, but the point is to make their icons show up as if they were connected even though they won't actually be of any use.
