Disc Drives Invisible (no Drive Letter)?
Jun 17, 2011
I just formatted and installed afresh Win7 Ultimate N on a WD1000GB. Since setup screen it recognized only 3 of 5 disk drive (all of same HDD).Before that I resized two of the drives with `EASEUS Partition Master 8.0.1 Home Edition` but I did so for the drives he actually recognized. (I accessed those drives through another OS which is installed on another HDD).It would see them in disc management but it can`t assign drive letter, it says : Disk Management Console view is not up-to-date... even the program can`t assign letter ot mess with the size of the drives

I have an *.iso file on my hard disc.What is the easiest was to map this �.iso file to a (free) driver letter (e.g. M ?I don't want to burn it on a DVD and access it in my DVD drive? Is there a Win7 built-in way?

When attaching a flash drive:
1. The autoplay pop up doesn't appear;
2. The device does light up initially;
3. The device doesn't show up in "Computer"
4. The device doesn't show up in Disk Management - just Disk 0 (system reserved, C: and I and 0 (CD ROM)
5. The device appears in Device Manager under USB controllers as a storage device but I can't access it.
6. This happens with all memory sticks and occasionally with ipod etc.. but sometimes for no apparent reason they work! All devices works ok with other computers.
7. 9 times out of 10 plugging in a device or turning on the USB attached printer will cause the computer to BSOD, usually with IRQL NOT LESS OR EQUAL 0X0000000A
8. Devices are never allocated a drive letter.
The only thing I can think of is that I repartitioned the external hard drive (which I attach to back up) which may have confused the computer with driver numbers? Possibly?! And I did fiddle with the System Reserved drive as I had back up issues and one of the solutions was to rename it, then I renamed it back again (I think).I'm running Windows 7 Home 64-bit, Avira anti virus and the computer is about 6 months old, working ok until a month ago. Can't think that we downloaded anything about the same time as the problem started but possible. I've tried to update all drivers that I can think of but the only one that needed doing was the Nvidia GeForce 7025 which was outdated.

I have 6 (2 internal, 4 external) hard drives, 2 CD DVD drives and one of those drives that read every kind of media card.
My external drives don't show in Widows Explorer unless they are turned on and they are always off unless I'm using them. So it normally shows my 2 internal drives and my DVD drives, but the media card reader shows up as 5 Removable Media Drives.
It there a way to make the media card reader not show unless I put a card in it.
It would clean up the view a lot to get rid of these 5 drives displaying all the time. I'd like to see only my 2 internal drives and my DVD drives. When I have all my external drives turned on and my USB stick plugged in it's just too much!

I lost my Event Viewer, and had to do a repair installation to fix it. Unfortunately, during the repair install, Windows decided to rename my second HD as the D: drive... it was K: before that. Now I cannot access any of my docs, pictures, music, or videos through the normal means... they don't show up in libraries or explorer, and apps like Restorator and Sure Thing (CD labeler) cannot find them. I think that means the paths are broken..?
It won't allow me to rename the HD back into K: (it's not listed as available). I can access the data by clicking Computer > D, and I can see the data is there, but its unusable as of now. Any ideas?

I still only have one IDE drive connected. On it there's an invisible folder, Boot, that contains a bunch of language folders, and a few additional files: BCD, BCD.LOG, BCD.LOG1, BCD.LOG2, BOOTSTAT.DAT, memtest.exe. The dates of these folders hasn't changed since May, which I suppose might've been when I installed Windows for the final time. So, what is this folder? Is it safe to delete? Did it have something to do with the hardware raid setup I used earlier? The motherboard is an ASUS P8P67 Pro.

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 have Win 7 home premium on an HP laptop with 4 usb ports. I have 2 Western Digital Elements 1.5 TB drives for backups. If I plug in one of the drives, Win assigns a drive letter, but if I add the second one it doesn't.
To troubleshoot, I've plugged each drive into every usb port on the laptop, and each port reads each drive alone, but if I plug in the second drive while the first is still in, it shoes up in devices but does not get a drive letter. I tried assigning a different drive letter to the device plugged in first, but Win still doesn't assign a letter to the second drive.

I decided to just revert to my old XP64. At first I was gonna try to dual-boot, but the fly in the ointment was all I had was an image on my external HD, which has about 100G of other stuff on it. My disc drive would not for the life of me burn an ISO image on any of my three DVD types. And the process of trying to find how to fix the drive problem and/or create just a bootable PARTITION on a HD without effecting everything else just drove me insane...which is kind of where I am now. After a week now I just have to get back to my project. lol And if that means no fancy windows 7 internet experience..while attempting a dual-boot scenerio workaround, I shrunk partition C and created a new 5G partition at the end of it. In EaseUS, I assigned it letter B and I set it to active, figuring it was to be bootable (wrong, I know). Additionally near the same time in Folder Properties, I unhid system files, folders...etc.
NOW the System drive showed as F! Then, attempting to use EasyBCD, it told me it could not find the BCD files to begin. So, naturally it had to do with that.I thought maybe it should have been B, but why would Ease US give me that letter option?After showing Easy BCD the file it seems to be OK....there. Also in Startup & Recovery it is listed in System Startup as the default system. But is it OK?Also, should it also be active. Did I inadvertently switch it by making the new partition active? What should I do to get it to boot properly. I AM planning on booting XP from a flash drive anyway, but still.

My backup software's profile database is expecting to backup to H:, which was the drive letter for my external backup drive back in XP. This drive comes up in Windows 7 as K, because Windows 7 has given my four usb card reader drives the letters F,G,H,I.
Disk Management will not show these four card reader drives unless media is inserted (connected vs. disconnected). I have changed the letters for F,G,I to T,U,W, but only because I have those types of cards (SD, CF, MS)...I do not have an XD or SmartMedia card for the one dang drive I really need to change.
What are my options, other than buying the cheapest SM card I can find to make the drive visible for this task? The SmartSyncPro database has many profiles, so remapping all those to point to K would be a major hassle.

I am running Windows 7 Pro. Have a external dual dock connected to a estata port. One of the drives assigned letter K often comes up as E and I have to change as application is looking for K. Another disk in this dock works fine. No problems. why this might be happening or anyway to prevent? Seems like when I go to disk management and assign K it should stay that way.

I have a toshiba satellite L750 running Windows 7 home premium, when trying to burn anything onto a blank disc I get as far as selecting my items and asking it to burn but it keeps telling me to insert a blank disc (which obviously I have). I have tried several different types of blank disc but it dosnt seem to recognise any of them.

So I have an bit of an odd and I think unique problem (as many searches came up with no solutions). Simply put, my boot manager is missing, but only when my windows install disc is not in the disc drive. It started several months ago and I just left it be, let the disc it int he disc drive and it was not that big of a deal. But just did a clean install couple days ago I re-installed windows 7 ultimate 64-bit on my computer (using an upgrade disc if that makes a difference).I formatted the drive with what I guess is a quick format (the option the install disc gives you). I have tried doing a repair with the install disc but no problems are found every time I try.

I deleted my existing OS then created two new partitions on the same drive. Then I installed Vista on one partition and that partition was properly named "c" as ususal. Then I started Windows 7 setup.exe from a different hard drive and let Windows 7 install itself into its own partition. When I got to "My Computer" the Windows 7 partition was labelled as "I" instead of the expected "C" which had never happend before when I did the same thing.
Does anyone know a save way to label the Win 7 drive as "C" while in Windows 7?

I have a new copy of windows y 64 bit ultimate. I currently use w7 64 home premium and it is on C drive and the drive is a sata 2 drive. But when I build my new system I want to install onto a new drive which is sata 6.0 and I have made a partition on that drive (letter M) for the O/S to be installed onto ( ive allowed 150Gb ).
So my question is when I build my system and am ready to install w7 can I install onto drive M on the new sata 6.0 drive?
I will unplug the old boot drive as I understand windows will boot to that if I dont unplug it, then when I have installed new O/S on the new drive, partition "M", I will plug it back in and format the old boot drive.
So then windows will boot to drive/partition M, if that works, and C drive will just become a data drive. I understand I probably will have to do some messing in bios, so any help with that will be good.
this will be my 1st build but I am not to bad with computers and have changed cpu's/HD's/gpu's/fans etc etc. but not mobo's and cases. And never changed a O/S onto another drive with a different boot drive letter.

My © drive only has about 2GB left free for use but my partition drive/extra drive (E) has 90GB free,
My documents is the one taking up the majority of the room on the © drive, it is possible to operate my documents out of (E) drive rather than © or will this cause problems when using iTunes, installing programmes/programme updates etc.
Would there be any benefits or draw backs from moving it over to the (E) drive or would it be more hassle then it is worth?

I have tried these discs on two computers (they're Sony DVD-RW's) and brand new, I open them and put them in the disc tray, I press "burn" and it either pretends to write on one computer and then says error after 3minutes (no data is recorded) or it doesn't detect the disc it keeps saying "Please insert a Disc"? I've tried literally everything and I doubt it could be the disc's because they're brand new. The windows fix it centre program identifies an issue but cannot fix it?

I'm running Win 7/64 Home Premium on my media PC with 7 USB drives, all connected via a powered hub.
Whenever I reboot (warm or cold), the sharing permissions are lost, generally to all, although every so often one of the WD drives will maintain it (the Seagate ones always lose them). I've tried using different ports to no avail. I've changed the properties of the drives so that I am the owner (as an Administrator). That doesn't help either.
I've read that Windows keeps a list of dynamic shares (or something like that) and that this behavior is by design as drives can be disconnected when the PC is not running. Is this true? I never had a problem with Vista, so this is definitely a Win 7 thing.

I just built a new computer which I am trying to set up identical to two of my present ones. The first terabyte hard drive is divided into 5 partitions, C thru G. Windows 7 is on C and Windows XP is on D. The other three partitions are categorized storage. I also added two more terabyte drives which are supposed to be H & I. Since my CD/DVD rom had assumed "H" in Windows 7, I reassigned the drive letter "J" to it. When I installed what was supposed to be my "H" drive, it showed up as "I". When I attempted to reassign the drive letter "H" to it, "H" is not on the list of available drives, So I tried renaming it to "Q" and then back to see if "H" would show up. It didn't. I went ahead and put the final drive in It was supposed to be "I" drive and indeed it came up correctly as "I" drive. So everything is in order now except for my "H" drive which still remains as "Q" until I can figure out how to make the "H" drive letter become available again. This si important to me since I do regular synchronization between my other computers and the drive letters need to be matched on all of them.I am not on the new computer right now, but on my last built one which has the same setup. I didn't seem to have any problem on this one since the drive letters are all on order. I've never had a lick of trouble getting them right on the XP partitions.What do I need to do to get "H" back on the list of available drive letters?

I previously shared my iTunes library from my desktop computer which was running Xp x64 Professional, and accessed the library through a M: drive that I could access on my laptop and other computers in the house. I set up the M drive following these instructions found here from LifeHacker and here from Microsoft previously.
I decided to try the same with 7 and everything goes according to plan until I get to the part where I go to add the new "M" drive and I can not click to "Assign the following drive letter" followed by letters that I can assign this new drive. I can only select "Mount in the following empty NTFS folder." Is anyone familliar with this issue and tell me what I am doing wrong?

I just got a couple of new HDDs to make notebook backups (clones) on. When I first formatted each one, using a USB dock, I set the drive letter of each one to U. Everytime I change the drives, the drive letter changes itself to E. I change them back to U but they change themselves back to E the next time I put them in the dock. What is going on here and how can I keep the drive letters from changing?

Recently I have found that when I attach an USB drive to my system I have to go into "Administrative Tools -> Computer Management - Disk Management" and manually change the 'Drive Letter and Path' for the drive.
Does anyone know how to get Windows to assign a drive letter to the USB drive automatically?

till 2 days ago, when I connected a USB stick or any other USB device, it was given a driver letter automatically and a window prompted for which actions I want to do.Now (after a windows update?), the drive doesn't receive a drive letter automatically. I have to go into disc manager a give manually a drive letter in order to be able to use the drive.

I had windows 7 on a SSD drive, assigned C: by windows 7, but it was full so I decided I'd clone it onto a bigger SSD drive using Acronis Disk Director. Went swimmingly I thought, both drives contained the same data. I wasn't too sure what my next step ought to be, whether acronis will have sorted it so that my new SSD now has the orginal SSD's drive letter or not. If it did, it will be mean a simple transition. But you guessed it, it left the drive letters the same, so when I booted up, it loaded from the orginal SSD. I then changed the original SSD drive letter, and used EasyBCD to remove the original boot and create a new one with the new SSD. Unfortunate now when I boot up Windows 7 I get a Preparing Your Desktop message for a couple of mins, but it's then followed by a screen with a cursor but no desktop icons or taskbar. It also seemed unresponsive to keyboard strokes.

I have a triple boot system:
C - Windows 7 Ultimate - SSD array D - Data - WD 640 spinner 1 E - Windows 7 Pro - 1st partition on WD 640 spinner 2 F - Windows 7 Enterprise - 2nd partition WD 640 spinner 2
Using Acronis True Image 2010, I keep 2 images of each OS on D.I'd like to put an image of C onto E, then make some changes to it. I think I tried this back in the Vista beta days, but can't recall if I ever got it to work, tempted to say "no".

My Windows 7 configuration is relatively bullet proof (ha ha, nervous laughter).My OS and programs are on C, which I image using RDriveImage every month after Patch Tuesday.My data is on software-mirrored D/F drives.So as long as I don't have a catastrophic event affecting my computer, a routine "drive failure" should be recoverable, with the worst-case being I'd be out a month of updates, but with a good recent image of the OS drive.Anyway, I was recently looking at my event viewer and I have "Disk errors" that occur whenever I run a full image of C.
The complete error text is:
Quote: Log Name: System
Source: Disk
Date: 7/13/2012 3:38:44 PM
Event ID: 11
Task Category: None
[code]....
There were two errors in February (none before that), three in March, four each in May and July.In April and June I did incremental images, so the "bad" area wasn't imaged, so no error.With all the above as background, what's the safest way for me to isolate and/or repair the area(s) of the disk with the errors?The errors are always logged within 1-2 seconds of each other, so I suspect it's just one bad area.And I have never, ever, seen signs of a disk error. No BSOD, no clicking noises, no impaired performance, even for a moment.
