Computer Doesn't See External USB Drives After Disconnect & Reconnect

Computer Doesn't See External USB Drives After Disconnect & Reconnect
Views: 5
Just upgraded to Windows 7 Home Premium from Vista. Vista saw the connected USB drives after disconnect & re-connect but W7 doesn't. Is there a setting I need to use to correct this? I've been using 'Computer Management' to assign drive letters in order to have the drives appear in Computer.

Working with the Computer folder

From the Computer folder, you can access locations such as hard disks, CD or DVD drives, and removable media. You can also access other devices that might be connected to your computer, such as external hard drives and USB flash drives.

Windows 7 and AutoPlay: CD won't start automatically

I have external USB hard drives. If I do nothing, ever time I start up my machine the "Options" box pops up for each partition / drive.

If I disable autorun per the above link, the drives still work, but do not open up the 'Choices" box.

But now if I insert a CD, it won't start automatically.

Is there a way to have external hard drives' and USB drives' autorun disabled but still have the CD players' autostart work?

In the Autoplay of the Control PAnel, I have the CD set to play/start with realplayer.but it doesn't.

Should I install USB 3.0 card?

2 of my recent USB hard drives are USB 3.0. My Win7 computer however only supports USB 2.0. I am thinking of purchasing and installing a USB 3.0 card to get better speeds when using these recent portable 3.0 hard drives.

Can't access USB drive

I have an older HP m7680n computer running Win7 x64. For the last year or so I've been using two 500GB Segate FreeAgent Go USB drives as backup media for my system. Normally I plug in whichever drive I need then boot the computer.

On start the computer boings/dings/whatever and an autostart window pops up asking what I want to do with the drive. During the day if I need to access the drive, I'd use Windows Explorer where the drive would be listed with it's name and a drive letter.

Three days ago my system stopped identifying the USB drives in either Win Explorer or in Computer.

The system will still ding/beep (whatever that sound is called) when the drive is connected (like a hot swap) but will not show the drive and I can't access it. Went to device manager and it showed up there by name under disk Drives and I could populate the drive (under volume tab of properties).

Setting up Epson LQ-570+ printer using parallel to USB adapter

I am running Windows 7 32-bit Home Premium. The computer has no LPT ports, so I bought a parallel to USB adapter in order to get this Epson LQ-570+ dot matrix printer working. Plugged in the adapter, powered up the printer, Windows auto-installs drivers for the adapter but says no printer is present. I downloaded and installed drivers for this printer (they do have a Windows 7 driver). Now, the computer seems to know that the printer is present, but it will not print. I have selected the USB virtual port as the port for the printer. I also tried selecting, one by one, all other ports (i.e. COM1, LPT1, etc.) but it would not print anything on those either. I tried plugging it into a different USB port, that didn't work either.
Interestingly, when I have the devices & printers open, and I unplug the USB cable that is coming from the printer, the printer is then greyed out. So, it is as if the computer knows that's where the printer is, and is aware that it is not currently connected. Once i reconnect the USB cord to the computer, the printer shows up normally (as in, not greyed out). But still not able to print anything.

USB Drives Wont OPEN!

So I put in my usb drive, so it shows up in my computer. But when I double click on it, it just hangs and doesn't do anything, the mouse looks like its loading something but nothing happens, so I have to enter the drive letter into the address bar and then it works.

External Drives not showing

I have used multiple external hard drives and secure digital cards on Windows XP, Vista and now 7.

However, on the Win 7 laptop from time to time I will plug in one of the ext hard drives and it doesn't show up. I know how to find it and get a drive letter assigned but does anyone have any idea why this is happening.

I have two ext hard drives and it has happened to both of them.

Ghost Drives ?-

I'm using Win 7 Home Premium x64 on an HP m7680n machine with 6GB Memory, 2 HDD (C and D), DVD RW (E), DVD ROM (F), 4 Card Readers (G, H, I, J) and a Segate Go Removable HDD (K).

Don't know why but recently in Win Explorer and/or in My Computer there are two (2) additional drives listed. In Windows Explorer #1 is listed as CD Drive (L) and #2 is listed as Removable Disk (M).

In My Computer both are listed as "Standard Disk Drives on USB Mass Storage Device" but, when I use the properties tab in Device Manager they are listed as Generic USB CF Reader USB Device.

I don't have any USB device connected except for the Segate Go HDD and the CF Card Readers (G through J) are hard wired into the system since day #1.

How can I get rid of these Ghost Drives ? and what made them suddenly appear ?

Please Select Program To Open: F:\ (external usb drives)

My Windows XP computer keeps asking me what program to open my external usb drives. I know to open them with "explorer" in the WINDOWS file on my hard-drive. How do I set it so that it will use the "explorer" program each time I try to open it? (p.s. It will not let me select "use selected program to open this type of file.")

USB suddenly very slow

I'm not sure this is a Windows problem, but since it's happening on my Windows7 (Ultimate - AMD Athlon 2core x64) machine,

For over 3 years I've been transferring large folders (about 4GB) onto one of my four WD MyBook Essential 2TB USB external drives (only one is connected at a time). It usually takes 10 to15 minutes to complete, but since last week it's been taking over an hour.

I tried it on the other MyBook drives and it was the same, so it's not the external drive.

I do not have the slowdown when transferring one of these folders to another internal hard drive.

Since this happened just after a Windows update, I attributed it to a glitch caused by one of the updates. I used system restore to back to before the updates, I keep a periodically updated clone of C: handy in case of disaster, so I plugged that one in, booted on it, and the problems was gone - for one day. Then it was very slow again.

It looks like something is reverting my USB 2.0 system to working like 1.1 or worse.
