Drive Recognized But Size Is 0?
Jul 30, 2010
I had Windows 7 installed under Western Digital 400 Gigabyte Driveat first I got the BCD error message so I tried a repair with the rescued disk. When I use the repair tool the drive is recognized as Windows 7 followed by the letters zero. If I boot to another drive both drives are listed but I cannot open the damaged drive and under properties it shows 0 GB. I tried using the command prompt and the bootrec commands and they appear to complete but still the drive will not boot and is listed as having 0 GB. I can not understand how I could have lost all the files unless the repair utility in trying to fix the disc wiped it clean.
what to do next short of reinstalling window seven.

My C: drive has been displaying a size of around 60 gb with 40 free even though it's a 300 gb drive. I thought the issue would resolve with a clean install, so I did that. Now I have a fresh install and i need to reinstall everything, but the problem isn't fixed. Below are some screen shots of the drive size:Disk Management, showing my C: Drive's full size ^Any suggestions of how I can reclaim this space?? I've tried a few things already to no avail. If you need any more information about my computer to help, let me know. This is pretty annoying, 'cause I want to use that extra space to install Ubuntu.Oh, I just rememberedWhen I look at the drive in Paragon Partition Manager, it shows the full Drive size, but says that the space that is missing from Windows is in use...

I'm having a bit of a problem with my DVD drives not being recognized. In a prior post, one of the fellows on this stream (Randy) solved the problem I'm having by suggesting that I edit the Upper and Lower Filters in the Registry. Unfortunately, I've lost this information. This time, I'll put it in a Jump Drive and lock in a safe!

The other day, my computer seemed to totally stop recognizing that my CD/DVD drive even existed. No icon in my computer, with or without a disc in it.

Why are SAN drives recognized as local drive while NAS drives aren't?I knew that SAN uses block level transfer to transfer data while NAS uses file level transfer. Does this has anything to do with why SAN drives and NAS drives are recognized differently by the computer?

After removing a virus, my 3rd hard drive is no longer being recognize. Myapologies if this should be in hardware, but I didn't know if it was something that had to do with windows 7The virus was anti-virus protection 2011.I used antizeroaccess, stopzilla,avg(which is my normal antivirus), malwarebytes, and kaperskyYes all of them. It was a nasty virus.My main hard drive c: shows up as well as my second drive. e:. My other drive used to show up as well as f: but since all of this it hasn't. Nothing else was changed besides resetting the cmos battery and a couple of disconnect reconnections, becasue the drive wasn't showing up.Ide channel 0 master and Ide channel 0 slave (set to cable select). are the 2 hd'sIde channel 4 is a disk drive.The 3rd HD is also set to cable select. but that shouldn't matter cause that's what it was set to before.I also tried another spare hard drive I had with the same connections as the 3rd hard drive ( marked as slave and cable select). It was not found either.not in my computer or in bios

I have THREE Hard Drives.
1) XP. Old PATA hard drive
2) Windows 7 SATA
3) New Hard Drive (E; with program files, back up, images, music.
Sorry, I had to edit this message as every time I went to type E colon, slash, it gave a smiley face. so the E; = E colon, slash to indicate E assigned hard drive letter, the new hard drive.
When I boot to XP with the new hard drive (E; shows up fine.
When I disconnect XP and boot to Windows 7, the new hard drive (E; shows that it installs fine (lower right in windows, shows that the OS see's it and says it installed fine), yet I cannot see it.
The configuration that does not work is two (2) SATA drives, one with Windows 7, the other, the new hard drive.
To be sure, I disconnected the Windows 7, connected XP (PATA) and booted again, sure enough, the new hard drive (E; is fine and shows up.
I then disconnect and attach the Windows 7 hard drive with the new hard drive, (I even tried moving the SATA cable around) and Windows 7 boots fine, shows me that it installs the newly found hard drive (E; but does not show up on my computer.
Now, here is what may, or may not be a bug.
The new hard drive was formatted NTFS in WINDOWS XP, the drive letter assigned was E:, when I boot to Windows 7, I have a Virtual Clone Drive which also has the letter E: assigned to it. Could it be possible that Windows 7 does not know what to do since the Virtual Hard Drive was there first and therefore, doesn't show the new hard drive when running Windows 7?
I have tried everything I can to get it to be seen in Win 7 to no avail. Again, it works fine in XP, but does not show up in Windows 7.
Has anyone heard of this problem before? Do I need to rename, or assigned a different hard drive letter to E:? If so, how do I do that?

I've got a relatively new 1tb Buffalo drive connected to a Laptop.Its been working fine, but now Windows 7 wants to format it.On connecting the USB cable the disk spins up OK, but then the Win message comes up saying it wants to format the disk.I'm far less keen on reformating the disk than Microsoft are because there's data on the disk that I want to keep.

I installed the Chrome OS IMG file on my flash drive and tried to boot from it, but it turns out my flash drive is now un-recognizable. I tried assigning a different drive letter in computer management, but it doesn't show up there. Sometimes it will show up and Windows will say that I need to format it, but the format always fails.Other flash drives are recognized by my computer. I am using a Lexar Jump Drive, but I'm not sure what model it is.

I'm using a Dell laptop Studio XPS 1640. Ok, I was about to upgrade to Windows 7 and it listed a couple of programs that needed to be deleted, so I uninstalled them. The 2nd or 3rd time I was required to restart my computer, it froze at the "Shutting Down..." screen for about 20 minutes. I waited and waited and decided to power down. I turned it back on, and it didnt say Windows was not shut down properly, so i figured it was ok.
However when I booted back up, I was going to eject and re-insert the upgrade CD. I hit eject, nothing happens. Hit eject again, nothing happens. I go to Computer to try and view the CD thats in my CD Drive....NOTHING SHOWS UP! MY CD drive is now UNRECOGNIZED by my computer! Now I cant complete the upgrade. Not to mention, the upgrade made me uninstall itunes and my virus protection, saying a new version will be installed automatically after the upgrade.

I have two hard drives; an older 20gb hard drive that is was forced to use to install Windows 7 and a 1tb Seagate Constellation ES ST31000424SS SAS hdd. Neither my bios nor the disk manager in Windows 7 are recognizing the 1tb drive. I have checked and rechecked the connections and power and both seem fine. In all my computer has in it:
-Gigabyte GA-X58A-UD3R mother board
-8 gigs of ram
-an i7 quadcore bloomfield processor
-nvidia quadro workstation graphics card
This is my first build but i have been looking for some time at different threads and i can not find a solution to the problem. The Constellation is an SAS drive that I'm using a converter cable to change into SATA connections. The url for the converter is: [URL]

I recently got an Acer 1810TZ with win 7 installed. My desktop runs win 2000 and the OS is currently less than 2.5Gb and I consider that bloated as originally it was more like 1.4Gb. I like to image and can easily put that on a dvd even without compressing the file.
On my new Acer the OS is taking up between 12 - 14Gb depending if I have a restore configured. I have partitioned the HD into several partitions. I only keep the OS and absolutely min stuff on my C drive and I have one partition dedicated to the page file only, 3Gb, and have all my programs etc installed on another partition. The recycle bin has also been reduced to 256mb on the C drive
Is there a way to significantly reduce the OS (C drive) to say less than 4Gb ?

I have an HP laptop which I recently upgraded from Windows XP Pro to Windows 7.
The flash drive (Lexar Firelfy 2GB) I was using on the XP OS can no longer be read under the Windows 7 OS. Information are stored in it (I am able to access it with computers other than mine), but my computer does not see them.
I have also tried different flash drives with the same results. Under disk management, my computer detects the flash drive but is unable to read it.

I've been using a 1TB iOmega external hard drive with my laptop for about a month and a few days ago it stopped working and isn't being recognised, the power light comes on when i connect the usb cable to the laptop but there is no noise from the hard drive at all and it doesn't show in disk management.
I took it into work with me and connected to my work PC (which runs XP) and it works fine, also tried it on another laptop which is running Vista and it doesn't work.
Laptop is an HP Pavilion DV6

I recently installed Windows 7 Professional 32 bit on my computer. I actually installed it clean, because I had Ultimate on it; unfortunately, the copy I obtained was not genuine, so I got a genuine Professional in its stead. This problem started in, but I figured when I got a genuine copy of Windows, it would be fixed. No such luck.n is pressed; I have to stick a paperclip in the manual eject hole. The Device Manager doesn't even show that a CD Drive is installed, neither does any other program. I tried editing the registry myself and deleting the "upper filters" line, or whatever it is, but that didn't work. I have been attempting to find drivers, tools, or anything else that could help with this, but nothing seems to be working.Here are the specs for my computer: Product Specifications HP Pavilion dv2945se Entertainment Notebook PC - HP Customer Care (United States - English)

my external Seagate hard drive is no longer being recognized by my system. The information on this is absolutely critical to me- I am a DJ and Producer and this particular drive contains all of my song stems, acapellas, instrumentals, sample kits, and also backups of every program I use (as well as my OS backup).
I just recently moved into a new apartment and my drive worked fine before the move 2 days ago. I do not think I bumped it or damaged it (seeing as how I always put them in safe places on the go) and it is now no longer working.

I have a My Book Essential 1TB External. I'm on Windows 7 x64. After I updated I've been getting a lot of bugs and extreme lag. I would click on the drive in My Computer, enter my HD password and the drive would open up with all my folders, etc. But then when I wanted to drag folders from my External onto my PC hard drive it would freeze up and automatically quit? Windows would no longer show the External as attached to my computer. No matter how many times I click on the icon in the task bar for WD SmartWare, it will never come back up. I have to restart my PC everytime so I can renter the External. I then installed all WD software from the Control Panel, didn't change anything or help at all.I have no clue what to do or what has happened, but my External HD is pretty much useless right now. I have very important files on there, I need to get access to this immediately.
EDIT: Now my PC has trouble recognizing the External. I tried it on my Laptop also, it doesn't show anything. It shows up under disk management sometimes. For example it'll show up then simply disappear.
Finally after restarting my PC a bunch of times and switching USB ports back and forth, this CD DRIVE E: icon appeared for the WD UNLOCKER. Whenever I try and double click on it to open it up, the green bar appears to load as seen below, then the icon just disappears, it will not open anything. When the "CD Drive (E:) WD Unlocker appears like above, my external HD will briefly appear under DISK MANAGEMENT. It shows up then just goes away along with the E: drive icon. I don't know if the USB cable that connects the External to my PC is bad or not? My external was working an hour before all this happened, so I don't understand what is happening? Also, when I click on "Devices and Printers", an icon appears with "My Book 1130". This is what is shows.
My External does light up when plugged into my PC and turns off when removed. I can hear a ticking sound which sounds like the HD working? All these problems seemed to start after I updated to WD SmartWare 1.5.1.6. I even unistalled all the WD software. For some reason whenever I try to install "WDSmartWare_Software_Upgrader_for_Windows_1.5.1.6 " it just sits there and hangs, doesn't do anything.

I have a toshiba external 200G hard drive. It was used on a Dell computer which ran Windows XP. I now have a new computer which runs windows 7. However when i connect the external hard drive to the new computer i start to experience problems with the files on there.
So there are a number of directories, my pics for example. When I click on it you can see the pics on some of the sub folders when you view via icons. Some you cannot see the pic, just shows a generic shot. When you try and open the pics / jpegs you get an error saying image not found, check 'full pathname / file' exists. The same is true for all files, docs etc
I have been able to load the same pics and docs via a cd, so it is a problem with my new pc recognising the hard drive as opposed to a problem with the files

I'm trying to install either the 32bit and 64bit version of Windows 7 Home Premium via DVD onto my system. I am booting from the DVD and setup automicatically runs. The Windows 7 setup GUI loads and it allows me to choose the language settings and then I get a prompt for,
LOAD DRIVER
"A Required CD/DVD device driver is missing...."
My System is
ASUS A8N-SLI Deluxe motherboard
AMD Athlon 64FX-55
3GB RAM
ASUS DRW-1814BLT DVD-RW drive (SATA)
2 x Hitachi Deskstar 250GB HDD in Serial ATA RAID 0
I have tried multiple drivers but there is nothing on the ASUS website for the DRW-1814BLT only a firmware upgrade which I have done.
This is extremely frustrating as both the motherboard and DVD-RW driver are from ASUS but there doesn't seem to be any support for Windows 7 on the download site.
My system passes the Windows 7 upgrade Advisor Report
