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

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).

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.

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.

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.

What's the difference between BitLocker Drive Encryption and Encrypting File System?
There are several differences between BitLocker Drive Encryption and Encrypting File System (EFS). BitLocker is designed to help protect all of the personal and system files on the drive Windows is installed on (the operating system drive) if your computer is stolen, or if unauthorized users try to access the computer. You can also use BitLocker to encrypt all files on fixed data drives (such as internal hard drives) and use BitLocker To Go to encrypt files on removable data drives (such as external hard drives or USB flash drives). EFS is used to help protect individual files on any drive on a per-user basis. The table below shows the main differences between BitLocker and EFS.

Two installations of Windows 7 in one computer
I currently have 4 drives in my system. Drive C has a copy of Vista, F is a 1 TB Internal Data Drive, H is a 1 TB Internal with Windows 7 and G is a 3 TB external. I currently have dual boot but don't use the Vista start up ever.

I am looking to replace the C drive with a SSD and put my windows 7 on it and use the other 3 drives for data. After I have installed windows on the new C SSD drive and I reconnect the H drive also with a copy of windows 7 on it will this cause any issues.

The Bios would point to C drive first so I would not think there would be an issue but just want to make sure or do I have to Clean off that other drive first.

External Advanced Format 4k sectors Hard Drive for Win 7, XP, Ubuntu
I'm currently looking for a new external 3.5" hard drive to pair with external eSATA+USB enclosure, to use across Win 7, XP and Ubuntu. I borrowed from a friend and tested a new WD 1TB EARS green drive as single partition storage drive connected internally at Win 7 and XP, it is fast, cool and quite compare with my other 4 internal drives, performance seems on par with my 1 year old WD Black. However, I also saw bad comments about this new technology of advanced format 4k hard drive for XP and Ubuntu.
Now, I'm searching for a good external 3.5" eSATA+USB enclosure and very soon going to buy the WD EARS hard drive because I'm out of hard disk space for my data storage. I need at least another 1TB, but I'm afraid that I may have degraded performance for using across Win XP, Win 7 & Ubuntu.
All my current hard drives are WD, so far so good. WD is my choice for good warranty service.
Shall I get this EARS drive as external cross platform single partition storage? If I buy it, which partition tool to use to ensure that it will get optimum performance across all abovementioned platforms?

How to Set A Custom Icon & Label For Removable Drives (Memory Sticks, Hard Disks, etc)
Geek or not, there is a time when you become bored with the standard icon used by your USB memory stick or your external hard disk drive. Each time you plug it into a new computer, the same boring icon and name are displayed? What about changing them to something fun and cool? What about using a Mario inspired name and icon? It is entirely possible and this tutorial will show how it is done.

USB Drives not displaying the auto run / popup
Whenever I used to insert a USB stick into a port, it would bring up a window that asked if you would like to open files in windows explorer. Now when I insert a USB stick nothing happens, you have to go to computer to open it.

Hot Swapping Drive Issues
I have two Hard Drive Docks for external drives. Just recently last couple of weeks, I've noticed that every time I change one of these external drives (movies, music, etc.) for another one it changes the drive letter and makes the old one unavailable until I've rebooted my system.
Before the computer would simply recognize the new drive and assign the same letter to it. But now it cycles through all the available drive letters until none are available and then the drive will not show up in my Computer, but does show up in Computer Management but without an assigned letter.
Also, if I turn off the hard drive dock and leave the same hard drive in it and then turn this back on it will give the drive a new drive letter. This is passing strange to my way of thinking

Behavior of Windows 7 with retrotech floppy drives
I've searched on my own for how Windows 7 assigns drive letters to floppy drives, but I've not hit the magic keywords to give me an answer. The reason I am asking is this, my current machine was an Windows XP machine for 8 years.

Then I decided to go to Windows 7 back when it was still in beta. Up until Windows 7 went RTM, my true floppy drive, cabled to the motherboard's floppy disk controller, was my "A:" drive.

My 'SuperDisk' LS-120 drive, cabled to a add-on UltraATA controller card, was my "B:" drive. When I clean-installed Windows 7 RTM, suddenly these two drives 'swapped' drive letters.

I'd like to put them back the way they were, but these two particular drives do not show on DiskManagement's drive list.

Is the only way to force a change the drive letter assignment for floppy drives in my case to power down the box, disconnect the SuperDisk drive, power up to login, then power down again,reconnect the SuperDisk drive, then repower the box again? Or is there a way from within Windows that I can force a drive letter reassignment?

And yes, I do still have a couple of hundred still-readable floppy disks, tho not so many 'SuperDisks'. If I burn them all to a pair of CDs, then what do I use the floppies for after that?

Help protect your files using BitLocker Drive Encryption
You can use BitLocker Drive Encryption to help protect all files stored on the drive Windows is installed on (operating system drive) and on fixed data drives (such as internal hard drives). Your can use BitLocker To Go to help protect all files stored on removable data drives (such as external hard drives or USB flash drives).

How To Make a Bootable USB, CD or DVD to Install Windows Using an ISO File
Did you ever format a hard drive, only to realize that the computer doesn’t have a DVD or CD drive? And now you need a bootable USB flash drive? Or maybe you thought the computer could be booted from a USB drive, but the version of the BIOS doesn’t allow for that?
Even if you don’t need it right now, go ahead and create your bootable Windows USB or DVD with us now. It’s not something you’ll need often, but that one time you do, you’ll be so glad you already have it!

How do you change hard drive icon images?
I have an odd problem that just occurred in Windows 7. I have several internal hard drives and 1 external hard drive. The external drive has always had its own unique icon and the internal hard drives all have the same icon image.
But somehow, the external drive now has an icon image of an internal drive, and my largest drive, a 1.5TB HD, is showing the icon previously used by the external hard drive.
I can't figure out why this happened, or how to change this back to the way it was. There is no performance issue, its just confusing since I've seen that external drive image so long I automatically go for the image when in my computer or explorer, and now that means I'm often selecting the wrong drive.
