USB External Hard Drive Keeps Disconnecting?
Feb 14, 2010
Windows 7 x86 I've got an USB External Hard Disk Drive (Samsung S2 Portable 500 Gb). In the last 3-4 days it keeps randomly disconnecting when in use... So, Windows starts, it runs fine for an hour or so (in use), then the magic sound strikes. After a couple of seconds it's detected again, and the whole show starts again. Sometimes it reconnects for 3-4 times in a minute.My USB drivers are up to date, I've unchecked all those Power Management things, I've installed the KB976972 update (tho I'm not quite sure I was suited for it ). I thought it was the cable's fault, so I left it on my brother's Vista PC for about 5 hours playing movies, and it worked...

Me and my brother built me a new computer from scratch (he did the building - i did the watching). I purchased an internal hard drive from Overclockers UK. It's a Samsung 1TB drive. I also have a 64 Solid-state drive in there as my primary hard drive that Windows was installed on and a couple of programs are installed on. My storage disk (the 1TB disk) is for all my music/films etc. Whenever I drag and drop a file into the Samsung hard-drive - it copies it rather than moves it instantly.When I had a laptop, I had 3 external hard drives and this is the way it copied files onto them.how I can get the internal drive to stop acting like an external drive?

This one is really bugging me because I have checked everything, and I cannot fathom out what is causing the disconnection apart from, either is a MB issue or driver issue...?Whenever, I turn on my computer and Windows loads it will not load the USB External HDD which has been set to AUTO so it will load when Windows loads. I have tried manual switch but this does not work either. The HDD is a combo HDD with Firewire and USB 2.x although, if I use Firewire instead its fine...?What is happening is that Device Manager in disabling the device for some reason, and the only way in which I can get Device Manager to recognise the "EXT HDD" is to search for new hardware and then it works...?The only thing that I found to be a little odd was there is no set power showing for the USB Mass Storage Device 0 mA I know it is the right port location because it is the same number. There is something I forgot to mention and that is the battery needs replacing. I have never had a battery die on me on a motherboard ever. The only conclusion I can think for the reason why the battery has been drained in the ROC Logo on the MB I used to leave on and I think it drained the motherboard battery. If the power is terminated, example the PSU is turned off then I have to reset the BIOS.

I have a 1TB external storage drive that uses its own power supply and connects to my laptop via USB 2.0 cable. For months I've had absolutely no problem out of the device, until the computer randomly decided to forget the device was plugged in. Now I'm lucky to get the device to be recognized by the computer at all, and when it is recognized, if I try to move anything to/from the device, the connection is immediately severed from the computer.I use this device for my backup as well as holding on to things I would rather not get rid of. All my drivers are up to date, I've done all the Power Management checking and unchecking that I've read from other threads found via Google search, and still it won't work correctly for me.

I have a USB external hard drive that I keep all my documents etc on (had it for years)I upgraded from Vista Home to & Home Premium then had to upgrade recently to Professional to run my Sage. Through all these upgrades my ext. drive ran fine. Occasionally the drvie letter would change if I had something else plugged into the USB, this was always easily corected in disk management by changing the drive path.The connection on the case packed up so I had to get the drive put into a new case, now when I plug it in the drive is assigned G instead of F, I tried to change the drive letter allocation in Disk Management but it won't let me as the program still thinks I have a second ext. hard drive which is labelled F. I suspect this has happened because when the usb connection broke the drive was disconnected suddenly instead of a proper eject.How do I get Disk Management to remove the inactive drive - i can't find any obvious way - eject, delete etc are all missing when I click on tools or tasks.

I just got an external hard drive yesterday, and have been asking a few questions on this forum. So far, people have managed to be very helpful with the previous questions, hopefully someone can do so here too.Reinstalling all my games to external hard drive, need to know if they will / how to make them appear / function properly in my GEF, whether added automatically or manually.I am basically going to have EVERYTHING put onto my 1TB external, and by everything I mean "Music, Pictures, Videos, Documents, Games, and maybe Programs". So, I made a folder for each of those things on it,and only now that I am reinstalling my games into the Programs one have I realized something.I am a bit obsessive about having a fully functioning Game Explorer Folder (GEF) with all my games visible in it. It's my assumption that when I install into an external hard drive, none of those games will be automatically added into the GEF. However, if I add them in manually (using the regedit method in the tutorial), should everything function properly, so long as I have my external hard drive on whenever I use the computer?I just need this to be confirmed before I start reinstalling more. Also, if not, please let me know if there IS a way to get them to show up in my GEF properly, or possibly move the GEF to the external hard drive or get it to recognize things from a different directory.

In order to make upgrading via a clean install easier -- and because I've been considering one for awhile anyway -- I'm looking at picking up a decent external hard drives right now... and can't seem to find a clear answer to something:
Will I see any drop off in quality of playback or computer performance if I use a drive like this (external, USB) to store all of my recorded videos. The tuner and Media center would save everything directly to this drive and play everything directly from it. Would that cause any problems at all? I notice that it requires no power adapter since it's USB powered, and it has a Interface Transfer Rate of 480 Mbps -- not sure how either of these apply to my potential use of it.

I have a 2TB Seagate hard drive that keeps dropping out in Windows 7. I use it as my main backup drive and when writing to it using either of the two backup apps I use the drive usually "disconnects" and I have to switch it off and on again to use it.I've tried using a different USB port and a different USB cable - same thing. I have run Windows 7 error-checking checking which reports no errors.When it disconnects, device manager shows that it is still connected and working but it definitely doesn't work. For instance, I can double click and open it but it shows no folders. Switching it off and then on fixes this but only temporarily.

Whenever I try to eject a certain external hard drive using the little icon in the task window, I get a message that it is in use. I am very careful to be sure it is not in use but still get the message. This is a data storage disc. I am not aware of any programs on it that may be running in the background. Is there a way to examine a disc to see just what is being used on it at any given time?

I've recently spent 2 days indexing an external hard drive and now the index has appeared to have gone, for most of that drive.
1) if I index an external drive and remove, re boot, and re attach the drive, will the index still work for the external hard drive?
2) if the answer to question 1) is yes, why can I not search all but the most recent files on this re attached drive?

I'm trying to backup my data on my laptop to an external hard drive. Windows isn't recognizing it for some reason.
The laptop is an HP running windows 7 and the hard drive is an Eagle Cansus. Using the windows commands in the control panel don't seem to help.

I have been using a commercial company to back up my computer for the last 2 years. Now I have decided to do my own backups. I already did the first back up to the external drive. Now its time to back up again, when I back up again, will everything be backed up again? Or just the files that have changed?

I was using Win XP on my Toshiba Satellite A215 S5818 until yesterday, now im using windows 7, so i insert my Transcend Storejet external hard drive, it was working perfectly like it used to. So i left my lap top running through the whole night because i was downloading something. I get up this morning and my disk isnt working. I was looking for a solution but no use, i tried to initialize the disk with disk management and i get the "incorrect function" error.
I noticed that i have two drivers that are not installed, both of them are "base system device", i tried to upgrade them automaticly online but windows cant find the drivers. The thing is i have valuable stuff on the drive, so i just need the files, i can get rid of the drive right away with the guarantee and get a new one.

Motherboard: Asus A8N5X
So after the hard drive fiasco that I reported in another thread, I got clever and decided to create an "Emergency Boot Drive" that would have Windows on it as well as some utilities for data recovery. I took one of the many old hard drives that I have floating around and plugged it into the computer AND unplugged my other two drives. Then I ran Windows Install off the DVD and installed Windows to the old drive. I installed my software. All was good. I plugged in the other two drives and tried to boot from the "Emergency" drive and it worked fine.Last step was to unplug the emergency drive from the motherboard, connect it via USB and try to boot. The BIOS sees the drive and I tell it to boot from the drive. So the computer is booting. The "Starting Windows" message comes up and then the system reboots. This happens everytime I try it.Does Windows reset the USB ports so that the drive suddenly vanishes?

I've been using a 1TB iOmega external hard drive with my laptop for about a month and a few days ago it stopped working and isn't being recognised, the power light comes on when i connect the usb cable to the laptop but there is no noise from the hard drive at all and it doesn't show in disk management.
I took it into work with me and connected to my work PC (which runs XP) and it works fine, also tried it on another laptop which is running Vista and it doesn't work.
Laptop is an HP Pavilion DV6

I have an 1T external drive plugged into esata port. It used to work and now it doesn't? When I boot up bios correctly identifies the drive as a seagate sata drive. When I look at device manager is says its a seagate SCSI drive and therefore the system doesn't recognize it at all? In device manager under drive properties it say " this device is working properly" I checked in disk management.
