External HDD Not Appearing In Disk Management - Drive Letter Not Assigned
I have an external HDD that works on any other machine I test it on, except mine. It was working and for some reason I recently needed to use it and it didn't work. It appears in device manager but not in disk management. A drive letter might not be assigned to it, I can't see it in disk management to assign a drive letter to it.

A Disk Read Error Occured On External USB HDD
I install Windows XP to external USB HDD and Windows 7 to other USB HDD. I have been using boot from ext. USB HDD for years because internal HDD is too small at that time and I keep it that way until recently I got problem.

I change from Dell620 to HP8560 and immediately it cannot boot from WinXP on USB. The only message is "A disk read error occured. Press Ctrl-Alt-Del to restart". I try to install again without any error during the installation process, but same error once it boot from ext USB HDD. I still can boot Windows 7 on other ext. USB HDD. I upgrade it to Win8 Release Preview and work smoothly. When Win8 RP expired, I keep using it without upgrade because I usually use it for less than 2 hours. Suddenly it cannot boot again like WinXP on other USB HDD. "A disk read error occured." I cannot find anything wrong with USB HDD. I can still access all files on USB HDD from any system. I just cannot boot from it.

How can I know if this is hardware defect or recently Windows apply patch/update that make it cannot boot from USB anymore ?

Bringing A HDD Online In Disk Management Does / What To MBR Of That Drive
I needed to copy files between two PCs and didn't have a USB big enough so I took the HDD out of my Dell Vista laptop and used it as an external drive to transfer the files I needed moving. When I connected it up to the destination PC running windows 7, the drive couldn't be seen in explorer. I had to bring the drive online in Disk Management in order to be able to explore the drive and take the files I needed off of it. All was OK until I put the drive back in the Vista laptop and then found that the drive wouldn't boot. All I get is a blinking cursor after the initial Dell logo screen. like as if the BIOS can't load the drive or something.Can someone please tell me what bringing a drive online in Disk Management does to the MBR of that drive?

Disk Management No Longer Automatically Assigning Drive Letters To External Usb Hard Drives
I use a lot of different usb hard drives in my shop. I have two basic enclosures, a generic one that uses pata drives on a usb 2.0 cable and an Apricon USB SATA 2.0 adapter.Suddenly when I plug in a new drive device manager does see the drive and installs it in device manager. I can see the drive in Disk Management but it has no drive letter assigned, and therefore doesn't show up in Computer. I can easily just assign a letter in Disk Management and the drive immediately becomes usable. However, I would like to get Windows 7 to resume automatically assigning a drive letter.

I have tried a program called USB DriveCleanup. What it appears to have done is remove all installations of prior USB drives and when I plug in a drive that has been in the machine previously it then goes thru the install again. Yet still no drive letter. I think the program is doing what would manually be done by going into safe mode and cleaning out all the entries that build up there that don't appear in normal mode, then removes them. Basically it seems like a shortcut to manually doing it.

I also tried a registry fix that essentially asked me to delete the upper and lower filters. This seems similiar to fix for CD/DVD drives that no longer appear in Computer. This fix also didn't work.I tried removing and reinstalling the chipset drivers. Still no go.Running Windows 7 Pro SP1, H55 chipset.

Unable To Open Some Files On External HDD
I recently purchased a laptop and hooked up my Seagate HDD to access different files on there (music and videos mainly). The HDD was originally connected to my desktop. Both systems run Windows 7 Professional 64-bit.

However, on the laptop, there are some files (it seems to be older ones) that I can't run from the hard drive. I have to copy them to my actual hard drive in order to run them. Trying to rename one of these files yields " File Access Denied: You'll need to provide administrator permission to rename this file" even though I only have one account on here which is the admin.

Is there any way just to do a clean wipe of the security restrictions so I don't have to worry about this?

Unable To Install McAfee Virus Software Due To Windows Update Error
I'm having a major virus/malware issue as my McAfee firewall protection stopped working suddenly. Called McAfee to reinstall the virus software and they were unable to install it. They said that since my Windows Update feature is not working (there is a big red X and updates are not downloading and installing) the McAfee installation is failing. Asked me to fix this issue first and then try McAfee installation.

I have an WD Elements 1023 external hard drive which I want to connect to my laptop which runs a 64 bit Windows 7 Home Premium. When I connect the device, it shows up in the device manager and the driver is installed properly.

However, it doesnt show up as a drive and in the Disk Management, it shows as Disk1 unknown. When I try to Initialize the disk, I get a error that the "The Media is write protected".

Its been a real pain as I have a lot of data init and unable to access it. [URL]

Initialize Disk Failed Logical Disk Manager?
One of the hard disks suddenly failed to initialized. The first problem I found on this disk was unable to open one of the zip files then the machine crashed. After I restarted the machine the HDD drive was missing from the Computer. My computer has 6 hard drives including the missing one. One is Corsair SSD for the OS and the rest are Samsung, Hitachi and WD all of them are 1TB. When I checked on the Device Manager the Drive is there and the device status is properly working. I checked on the Disk Management and I got a message to Initialize the Disk then I followed the instruction. Again I got an error message " Virtual Disk Manager - The system cannot find the file specified." On the Disk Management windows the status of the Disk is "Unknown 931.51GB Not Initialized- Unallocated". I tried to initialize but the same error I got. I did not name this drive but it named automatically RV 01 and the Location is 0.I use Acronis Disk Director to fix the problem but it cannot change the status to online. What I did last week was I installed some programs to the Drive X instead of Drive C.My computer OS is Windows 7 64bits all the drivers and software are updated.

WD 2TB External HDD Is Not Recognized Under Disk Managment
My external HDD (A WD 2TB My Book) just up and quit on me while I was using it today. My computer was no longer recognizing it, and I could no longer access my files. My computer still acknowledges it under drivers however, and it claims all the drivers are up to date and that the device is working properly. I tried going into to Disk Management to see if I could do anything from there, but it isn't even recognized there. There is however a Disk 1 but it is unknown and not initialized. I'm assuming this is my external HDD since its the only external disk I've used on my computer. When I tried to initialize it, it failed due to an I/O device error although the error prompt didn't refer to any specific problem.

Cannot Initialize USB Hdd?
I have several old Western Digital hard drives with many files on them. I tried to access those files by connecting the hard drives using a IDE/SATA-to-USB connection that I bought for this purpose. The instruction said to put the jumper in the "Master" position.The HDD did not appear in Windows Explorer. However, the IDE/SATA-to-USB is recognized by Windows 7 and the hard drive appeared as "Disk X" in Control Panel's Disk Management with a note "not initialized". The HDD was spinning. Under "Volume" it also said not initialized. So, I tried to initialize it and a screen appeared with a check mark on MBR type. When I click "initialize" an error appeared "Device not ready".I changed the jumper settings but with the same result.The same results when I connected these HDDs with the IDE/SATA-to-USB on a another computer with Win XP SP2.What needs to be done?

Data Recovery - How To Initialize Drive / Unable To Access
My power supply on my old comp died, so it was time to upgrade computers, I went from running windows XP to windows 7 now. I saved my old "previously upgraded" 320g wd internal drive to recover the data to my new machine. I got an external drive enclosure, installed everything but windows is telling me I don't have "access" to the drive. When I go into disk management, it sees the drive but it's not initialized, nor will it let me initialize it when I try.

HP Windows 7 - Sata HDD - Disk Read Error?
that the system doesn't recognize the Sata HDD on which Windows 7 is installed. I first thought the the HDD was done, because the system recovery couldn't be started and every action was followed with "disk read error". The next step I took was booting with Ubuntu live and there was the surprise, Ubuntu recognized the HDD and all the folders were there, so it seems the problem is not with the HDD but with the OS. What next step should I take

Replace Disk 1 With Disk 0 In Computer Management?
Its a bit complicated to state my situation, anyways, I have 2 HDD, and the PC won't boot if I removed the old HDD even though I've formatted the old HDD and win7 is on the new HDD.I have 2 physical HDD in PC

(1) 80GB old hdd and noisy. (not SATA)
(2) 500GB SATA hdd and sexy.

My powersupply only supports 1 SATA connection, and I don't have a DVD-Rom.I've unpluged the (2) and replaced it with my dad's SATA DVD-Rom to clean install Win7 64bit on the old (1), after I've finished, I removed the SATA DVD-Rom, I plugged back the (2), installed Win7 64bit ISO again from the (1) on (2), then I organized everything and split the (2) to E: and F:.

Everything's fine until I wanted to remove the old noisy hdd. When I did that, the PC started to bitch on me and didn't want to boot from (2).I've tried to rename (2)'s letter to C:, but it gave me 'invalid parameter' error. I doubt that it'll work by itself since it'll need to rename all the softwares' locations and I went through another way, renaming (1) to a random letter like K: and wishing that'll work, I've restarted, shutdown'ed, and unplugged (1), didn't boot from (2).So it left me with only and only solution is by clean install, -but- I can't do it since I don't have an old dvd-rom nor do I have 2 SATA PSU cables... so I go back to the begging and...know that I have only 1 option by installing the win, is by the iso.

Now, what I'm thinking is that there's a possible way(maybe?) that I can replace Disk 0 box by Disk 1 box.Here's a picture to clarify it.So that's it, notice the 2 boxes down there? I'd like to switch Disk 0 by Disk 1 and then remove the old crappy 80gb hdd.

Disk Numbers In Disk Management Matters?
After adding two new SATA hard drives in my computer, I noticed that Disk Management lists SATA Drive C (which contains Win 7) as Disk 2. The other two drives are listed as Disk 0 and Disk 1.Since I connected SATA Drive C in SATA port 1, I was expecting to see it listed as Disk 0. SATA drives D and E are connected to SATA port 2 and 3 but are listed before the one connected in SATA port 1. And since the computer seems to work fine, I'm wondering if the disk numbers listed in Disk Management matter at all?
