Win 7 Fails To Assign A Drive Letter To A Usb Drive


Windows 7 fails to assign a drive letter to a usb drive (in this case an olympus ls-10 recorder). I have a plug and play ls-10 recorder. It works fine on all of my xp systems. When i plug it into my windows 7 64 bit system, "nothing" happens. Upon further investigation, the disk manager sees the drives (there are 2), but no letter is assigned. I tried assigning, but i keep getting a message that asks me to refresh, restart or reboot, none of which works. I have tries to uninstall and install the devices - same result. I tried to assign the drive letters in command mode, but i get a "no volume" error. Ny suggestions?

Win 7 Does Not Assign A Drive Letter

Windows does not automatically assign a drive letter to any of my usb hard drives or flash drives, if i go into the disk management utility the drive is always sitting there online and active, and all i have to do is right click and assign a drive letter and everything work as usual. However that is super annoying and there is no reason windows shouldn't be doing this for me. I assure you there are no driver problems corrupted drives, jumpers or anything out of whack, i am an it guy myself. I have just never ran into the situation and couldn't find an answer after looking on here for 20 minutes and googling around and checking other sources.

Can't Assign A Drive Letter / Mount In Disk Management

Windows 7 shows external drive in device manage but cant assign a drive letter/mount in disk management. I have an external seagate 250 gig drive which currently works fine on my xp netbook and which worked fine on my vista laptop until i "upgraded" to windows 7 (manufacturer's upgrade via dvd).

Now the external drive (ntfs) is seen in device manager but does not mount. In disk manager it just labels this drive as "disk 1 online". If i try to assign a letter i get an error message that cant be done because the console is not up to date (ie the message tells me to refresh, restart the manager, or the computer). Of course none of those 3 options work!

Assign C: To A Usb Drive

I would like to be able to carry my system drive between office and home in order to use the same configuration of programs on either desktop. Is this possible? Is it practical? For example, will a usb drive be too slow for running the system and program applications?

I have bought 2 identical machines both with legitimate windows 7 installs. My idea was to be able to clone one to the other at will, thus ensuring both a reliable backup and a clean install (this seemed specially desirable after "easy transfer" scrambled my computer. ). I found however, that although i successfully cloned one (no1) to the other (no2), no2 lost the "activation". The phone call is automated so i wasn't able to ask if i would find after "activating" no2 that next time i went online no1 would automatically be remotely deactivated. Perhaps someone can answer this?

Matching Drive Letter With Physical Drive

I know there must be a simple way of doing this. I have 5 sata drives on my windows 7 system. The boot drive (c:) and another drive (e:) are 150 gb wd raptors. The two raptors are connected to the mobo's sata1 and sata4. But how can i tell whether the c: drive is on either sata1 or sata4? All in can see in the device manager is the drive s/ns. In disk management, all i can see are the drive letters and the drive type, but not the s/n. I know that i could power down, unplug one of the drives from the mobo and see what happens when i reboot, but i was wondering if there was some way to find out from the os.

The only other way i decided that it might be possible to find out is to use the bios to examine the s/ns and try booting from each drive using the bios and see what happens.

Drive Letter Changes

I recently installed win 7 on my computer. I have three sata drives in it. Every time i reboot, two of the drives switch letters. Any way i can control this unwanted change of letters? D and e. Disk "d: appears in explorer, however, i went to disk management, and even though disk "d" is shown only on the bottom part (without a letter), it does not appear on the top list of drives.

When i tried to activate the disk or change the drive letter, it tells me the disk management is not up to date. I tried refreshing and restarting, but nothing works.

Change Os Drive Letter From D: To C:

Can i change an os drive letter from d: to c:? I have a desktop with a dual boot setup. Vista ultimate 64-bit on c: and windows 7 pro 32-bit on d: these are two separate hard drives. I want to run with only the windows 7 os and do away with the vista os. I can simply disconnect the unwanted drive and run a repair from 'boot with cd' to write a new bottmgr, but i am uncertain if this will work? Also will this process effectively reassign the drive letter of the windows 7 os?

If it does change the os drive letter to c: will all the applications etc run properly as they were loaded whilst the os was in fact a d: drive?

Dvd Refuses To Take On Drive Letter

I just recently upgraded my windows vista 64-bit to windows 7 64-bit. After the upgrade, a problem came up. My dvd drive no longer appears in my computers, but it does show up in the device manager. I have tried all methods listed on the internet like reinstalling the driver, but to no avail. Then i tried microsoft's mats_run. Dvd and it identified a problem. The problem was that my dvd drive was not assigned a letter. However, the dvd drive "refuses" to take on a letter. I even tried assigning a letter to the drive myself via "disk management. " So my question is, why is it doing this and how do i fix it?

Upgraded from windows xp to windows 7. Before upgrade i installed a new larger hd. It was the only hd in computer. Installed windows xp and no programs. Followed by installing windows 7.

Mystery Drive Letter In Windows Explorer

I have a strange problem with windows 7. When i open "my computer" i have a drive named "local disk q" which seems to be a phantom drive. I can't get any information on it and, while i can rename it, that is all i can do. It does not open and there are no clues as to where it is located or why it is appearing. (It does not appear in the drive management area, only in windows explorer and any box that refers to the drives on the computer. ) Does anyone have a clue as to how to get rid of this or where it may have come from?

Win7 Change The Drive Allocation Letter

I have a dual boot system vista 64 bit on c: (which i would love to get rid of) and i allocated b: as the drive letter for my windows 7 64bit op which is the default boot system. I've had one or two problems with installing ati drivers for one but my main problem seems to be the inability of w7 to recognize large usb drives (iomega- seagate freeagentgo) both should but won't be recognized.

I've tried disk management to change the drive letter (as b is supposed to be reserved for floppy drives) but it won't let me. I have tried to remove vista and restore images of 7 but they always fail, so without a massive reinstall how can i change the drive letter to anything but b. I do have a lot of drive configuration and cloning tools so if any ones ever been in the same boat help me i'm sinking fast

Programs Not Functioning Properly After Drive Letter Change

I am running windows 7 home premium 64 bit. When i first partitioned my hdd, the 2nd logical drive was labeled j:, which was the next available letter after all the optical drives and built-in flash memory readers. I prefer to label it d: (to immediately follow from the boot partition which is c:). I used the disk management feature to change the drive letter from j: to d: (and of course moving the rest of the optical drives and built-in flash memory ready by 1 letter).

When i run some programs, i get this error message: "there is no disk in the drive. Please insert a disk into drive deviceharddisk4dr4. " The options to click below that message are "cancel", "try again" or "continue". For some programs, like google chrome, microsoft works word processor and spreadsheet, clicking on any of the 3 options will allow the program to run normally.

For other programs, like windows live movie maker, clicking on any of the options will result in a "drive not ready" message and lead to more problems. For example, i cannot load any of my existing projects because i cannot get to the screen that allows me to navigate drives and folders to choose my file.

I uninstalled and reinstalled movie maker, but the problem is still there. Seems to me that it is not the individual programs that are causing the problem but something in windows 7 itself. How do i get rid of the error messages and get the programs to function normally? Do i have to edit the windows 7 registry? If so, what exactly needs to be changed?

Can't Eject Usb Hard Drive, Drive Always In Use

I have a 500gb maxtor onetouch 4 external usb backup drive that is set to do weekly backups with windows backup. This works great except that everything and their grandmother wants to spin the hard drive up whenever possible. This is not an ideal situation: with exception to backup, this drive is not used for anything. So i had a great idea, i'll keep the drive unmounted until i need to backup which then a newly created scheduled task would mount, backup and unmount when done! Well, turns out, windows doesn't think so. And this makes me a sad panda.

Backup Fails Due To Corrupt C: Drive

Recently backup failed claiming a corrupted c: drive prevented some user files from being copied. On startup disc check is run automatically and reports a fault due to recently installed/upgraded software application and states that the solution is to restore to an earlier point. This fails on a series of restore points citing corrupt c: as the problem. (Some loop huh!)Regcure has been run and sped things up (a lot!) But not resolved the issue.

Windows 7 family premium is being run as an upgrade from the originally installed vista. Ny ideas please? I really don't want to reboot and start again if i can help it, especially as its an upgrade not original installation. (Most of me wants to go back to xp if i must stay on windows!).

Secondary Drive Or Any Usb Drive Is Not Accessible

After installing windows seven on my primary drive (followed the installation procedures for 7 on 32 bit xp pro) all works fine except my secondary drive or any usb drive is not accessible.get error message they are not available. They are in the setup bios and in devices, but in my computer if i left click i get the error message.

However my secondary disk is a sata 500 gig drive. Windows 7 will recognize dvd/cd drive but only the "c' drive (of hard drives)> i have tried usb drives in addition to the sata but it does not read them, only tells me they are not accessible. The one exception was the windows easy transfer data sent to a usb disk made prior to loading windows 7.

Usb Flash Drive - Usb Device Is Not Recognized

I have tried 4 different usb flash drives from different manufacturers and my usb hard drive from western digital. Windows 7 recognizes it until i start transferring files. Then it can't find the drive. When i unplug it and plug it back in, i get a notification that the usb device is not recognized. After i restart the computer, it does the same thing all over again. I ran vista before windows 7 and never had this problem. I am very frustrated. I must have access to my flash & external drives or windows 7 is useless to me.

Usb Shows Up As Cd Drive

I am on an hp pavilion dv7 notebook pc running the current windows 7 ops. I have my lacie drive plugged in and when i look in the device control panel i see it. Windows says it is running properly.
When i try and access it i cannot because it tells me to insert a blank cd. It thinks it is a cd player. Details of device shows it to be a disk drive. How can i change it to a usb? This is shown right below the disk drive, but how do i engage it? Simply clicking on it does not work.

Usb Drive Not Accessible

I have several external drives, all of which worked just fine under windows 7 originally using default drivers. About 1 month into working with windows 7, two of my external drives are now inaccessible, giving the following error message.

"Usb device not recognized: one of the devices attached to this computer has malfunctioned and windows does not recognize it. " Device manager shows it as a flagged "unknown device. "

Worked fine for a month or so, stopped working, doesn't sound like a driver issue to me. First one drive stopped working under windows 7, then about a week later the second stopped working under windows 7. Both drives still work just fine under xp. Any suggestions?

Can't Copy From A Usb Drive

I can copy files from a cd why can't i copy from a usb drive? I know this is hard to believe but i'm having even more trouble with windows 7 security than i had with vista. At least with vista it was easy to turn off uac. So far with windows 7 i have only succeeded in turning down message levels so i get fewer messages for each failure.

I am trying to copy files from a windows 7 desktop to a usb drive and then to a different machine's windows 7 desktop. The target win 7 os say's i don't have permission even though i'm using an admin user account not a standard user account. The files on the original desktop were copied their from a cd without any problems being encountered.

Usb Flash Drive Problem

I have windows 7 on a dell inspiron 1525 (originally came with vista). Every time i use my flash drive to read or play files, or even just view files on windows explorer, it freezes up. The only way to fix it is to unplug it and wait, otherwise it will just sit there with a blank white screen. This never happened on my xp desktop. But what i wanted to do was back up my system. It seems to work until it reaches 25%.

That's when it freezes again. This also happens with a blank cd. The only external memory (besides an external hdd [i never tried that]) that works is a sd card. I don't have a high enough memory card so i'm stuck. I need something to back my system on.

Boot Up From Usb Dvd Drive

I know it can be done, but my bios only has the option, apart from the 'obvious' ones, of booting from usb flash - is that the same as the external usb dvd drive? (Have to use external dvd drive as one in laptop defunct) if not, i will have to boot from a usb stick - have copied the instructions from http://www.Istartedsomething.com/20081104/tip-make-your-pdc-2008-usb-hard-drive-a-bootable-windows-7-install-disk/ to make my usb drive ready, but some sites say it has to be ntsc formatted, and also made bootable with the bootsect utility. Which is correct?

Save As To A Usb Thumb Drive

My usb thumb drive is not cooperating. I can drag (or send) a file to it from the desktop if i "provide administrator permission to copy to this folder. " I can create a new file on the thumb drive. I can even open and edit the new txt file - but "access is denied" if i try to save the file (to its original name and place).

Some applications will save to the thumb drive with an odd message, but the real trouble is an application that flat out refuses to save to the thumb drive. Wordpad says "you don't have permission to save in this location.contact the administrator to obtain permission. "

How to fix the thumb drives?
