External Usb Drive Showing As Unallocated Space


I installed windows 7 rc on a brand new pc to try it. I got it running then plugged in my wd mybook 750gb external usb drive to copy some files onto the pc. That worked fine. I then shut down the pc. When i tried to connect the drive to my xp laptop it no longer shows up as a hdd. If i look in devices it's there but showing as unallocated space in the hdd management console.

I have over 300gb of backups on that drive and will be pretty *** off if windows 7 has trashed 2 years worth of data. I'm assuming the file allocation table or something has been corrupted?

How To Use Unallocated Disk Space?

I shrunk my c: by 40 gb and got this unallocated space. Now when i try to create a new volume out of this space, i get the message " the operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed operating systems from any volume on the disk(s) (except the current boot volume). Are you sure you want to continue?" On searching i found that windows 7 home premium supports a max of 4 volumes. This is my disk management image: http://goo. Gl/r4nd what do i do to make it usable?

External Hard Drive Space Discrepancy

I have a 500gb western digital external hard drive which shows i actually have a total of 465gb (i understand this). Currently it says i have 277 gb free but the files i have saved on there amount to no more then 100gb, so shouldn't it have 365gb available. Also about once a month it says there is not enough room to complete a back up even though on my c drive it shows i only have about 135gb of stuff, so i have to delete my previous back ups and start again, why is this  .

External Usb Drive Initiated To Late

Today i switched from vista to windows 7. Unfortunately i noticed some problem with my external usb drive: wd mybook 320 gb. When i log in, in 75% of trials there is a pop-up that new storage device was found (the same when you put usb flash into your pc). Strange, because the disk is plugged into usb all the time. It means that when i log in just for a second the system does not see the drive, which has some some nasty consequences:

- Shortcuts directing to files on external drive are damaged
- Outlook cannot open archive folders on external drive (i have outlook in autostart)
- At startup system cannot reopen explorer windows (path not found)
- Etc.

After this faulty second everything is normal, i.e. Disk are discovered properly and the are working well. I tried to turn on login password (to give system more time), but it didn't help. This issue appeared neither in xp nor in vista. Is there any way to make system discover external drive sooner?

External Usb 2.0 Hard Drive Not Detected

I am running windows 7 and trying to plug my 200 gb hard drive from an old computer with xp into my new computer via usb 2. 0 from an external enclosure. The external enclosure is has its own power source and does not require drivers. When i plug it in the usb port i hear the chime indicating window detects an external device and it will appear under usb devices in device manager but only for about 10 seconds and then disappears.

It never shows up under disk management nor under computer as a mass storage device. I have tried using other usb cables/ports. I have tried exchanging the external enclosure for a new one thinking the first was faulty but that didn't help.

My laptop does not recognize the built-in dvd or an external usb dvd drive. But if i configure the bios to let the laptop booting from the dvd drive then the dvd drive worked fine. It could read the disc. One time, i removed nero program from the system and i don't know whether some windows files got corrupted.

Access Denied With External Usb Hard Drive

I messed up on this one. I was removing advanced sharing on an external usb hard drive. First i turned off sharing, then i went to the security tab and removed "everyone" which was the only user listed. I got a warning that this would only allow the originator to access the disc. Since i was the originator i clicked okay. Bad move! Now i cannot access the disc. I now realize that i should have added "administrator" to the users when i deleted "everyone".

Now for the question. Does anyone know how to restore permissions on this ntfs external usb hard drive so it can be accessed? Since access is denied, i cannot restore permissions with the advanced sharing wizard in win 7 ultimate.

I keep getting change permission to open file messages when trying to access files. I had a pc with windows xp home addition on which packed up. So i've just brought a new laptop windows 7.

External Hdd And Dvd Drive Loose Usb Connection

I just bought an acer aspire asa3810tz with windows 7 pre-installed. In addition i have an external hdd (wd 500 gb) and a iomega superslim dvd usb drive. When i plug them in they are recognized, and i can sometime use them for a while, but then suddenly the connection is lost.

I have searched every where for a solution, but the solutions i have found so far was about nvidia chipsets and making sure that the computer was not allowed to turn off the usb ports. Nothing have though help.

I have tried updating windows until no more updates were available and updated drivers based on drivers from acers support pages but so far with no luck. In case there is other solutions out there, then please just point me to them and i will try them out.

I also saw an answer in which it was requested to create a log and so i did hoping i could use it, but unfortunately i did not understand it. In case someone can uses that usb trace i also put it on skydrive: http://cid-d6ee7fade4f53730. Skydrive.live.com/browse.aspx/. Public

Creating System Image On External Usb Hard Drive

Creating a system image on an external usb 2. 0 hard drive
Applies to: windows | windows 7 | system repair and recovery

We have a new hp g60-533cl notebook running windows 7 64-bit home premium. Attached to it is a new hp usb 2. 0, 500 gb pocket media drive (pmd). I use windows 7 to create a system image of the laptop's hard disk(s) onto the pmd. In the windows 7, create a system image dialog box you see the following selected drives:

Drive used space

System (system) 33. 66 mb
(C:) (system) 40. 76 gb
Recovery (d:) (system) 9. 87 gb

Space required to save a backup of the selected drives: 50. 66 gb

I watch the winodws 7 progress thermometer as it creates the image for these drives, and you see that all 3 drives are "imaged" to the pmd. Once the process has successfully completed, the pmd has a folder on it titled, "windowsimagebackup".

I then right-click on this folder and select properties. It provides me with the following information.

Location: f:
Size: 33. 9 gb (36, 501, 698, 638 bytes)
Size on disk: 33. 9 gb (36, 501, 749, 760 bytes)
Contains: 21 files, 4 folders

My question: why are there only 33. 9 gb of information saved to the image, when the 3 drives listed above required 50. 66 gb of space? Is all of the information listed above actually being saved? What's happening ?

External Usb Hard Drive Problem, Hotfix Won't Work

When transferring larger files from my computer (windows 7) it stops, and then won't recognize my usb device. Another forum identified the nvidia chipset and found a hotfix, http://support.microsoft.com/default.aspx?Kbid=976972. I downloaded and ran it but unfortunately i get the message "this update is not applicable to your computer".

I have an acer aspire x1800 (new, which the retailer replaced thinking the usb issue was a motherboard problem), but the same problem still exists on my replacement computer when copying files to a usb external drive. My processor is intel 2 quad cpu @2. 33 ghz. Ram is 4gb. My ide ata/atpui controller is nvidia nforce serial ata controller.

Excessive Space Being Taken Up On C: Drive

(b) drive not showing up after windows 7 64 bit install. Drive (c) also has less than half its capacity available after a clean install. I just "custom" installed windows 7 ultimate 64 bit after running windows vista ultimate 32 bit. I followed all the defaults for the "custom" install and didnt do anything fancy, pretty much just clicked "next". Everything booted up fine but now when i go to my computer folder, only one of my internal hard drives is showing up (c). It is also showing my external hardrive - but not my second internal hard drive (b). Also, (c) has only 112 gb free of 298 gb after a clean install of windows 7. I know windows 7 cant be that big.
So:
(1) cant find second internal hardrive (b)
(2) excessive space being taken up on (c)
What gives?

Not Enough Space On Partitioned Drive

I have  a partitioned hard drive and "c" drive is only 29. 2 gb. What, if anything, can i delete in windows vista to get the required space i need to upgrade to windows 7? I have 7. 62 gb free and need another gig. I don't want to screw up vista in case of a problem with the installation and i don't want to do a clean install because i don't want to lose any programs.

Cannot Manage Backup Space On More Than 1 Drive At A Time

Cannot manage backup space on more than 1 drive at a time; can view backups on more than 1 drive at a time. I make image and regular backups to 2 different usb drives - because you do not know when a backup drive will fail. Win7 backup and restore gui allows one to view backups on multiple drives at same time via "select another backup to restore files from".

Manage space only allows to manage space on the currently configured backup drive. Further - if modifying the configuration to select a different drive - you are forced to start a backup before you can manage space on that drive. - "Save settings and run backup" there may be little space on the drive - so i will have to either cancel the backup after started or configure a useless  small backup so that i can then manage space on the drive.

Hard Drive Space Usage Under Win7

I just upgraded to win7 (64 bit). My c drive (intel ssd) has ~75 gb space. When i click on "computer, " it says that the total free space is 25gb (i.e 75gb is used up). But the space occupied by all files/folders adds up to only ~24 gb (~21 gb of this is occupied by "windows" and "windows. Old" folders, ~2. 4 gb by "program files" and "program files (x86)", and very little by other folders/files).

How can i find out what is taking up the rest of the space? I have emptied the recycle bin and have done disk cleanup. In addition, in the advanced settings list, i made sure that "show hidden files, folders and drives" is selected. I also unchecked "hide protected operating system files. ".

Low Disk Space On Recovery (d) Drive

I just switched my dell studio 15 from windows vista to windows 7. Once i got everything set up, i started receiving an error message that reads "low disk space on recovery drive". I have already gone and changed the program files to default to the c drive by going in through the registry (?) But am not sure what else i can do. I have tried uninstalling programs, but it tells me that i don't have enough disk space to do so. I only have the following folders in my recovery partition: dell, perflogs, program files, sources, tools, users, windows. Any suggestions of what i should do?

Will Upgrade Installation Require More Space On Boot Drive ?

I have a very small 32gb boot drive with vista premium installed. Will upgrade installation require more space on the boot drive? The boot drive i have is an 32gb ssd. Since ssds are so expensive i ordered this small one as a boot drive only. So will i need space available on the c drive to upgrade my windows vista premium 64-bit to windows 7 64-bit? I have a secondary hard drive as my f drive. It is 320gb and contains all my programs and games, leaving about 200 gigs left.

If space is indeed required from my c drive, is there an alternative way to upgrade?

Upgrade To Win7 Wrt Hard Drive Space

I've been thinking about upgrading to windows 7 for a little while. I've been reading the system requirements (i meet all of them) but i noticed that i have to have 16gb of free space on my hard drive. My laptop is a basic (ish) spec so hdd space is at a premium. Will it always use this 16gb when everything is finished or is it just temporary.

What happens to vista? I've seen on some other forums that it keeps it installed. This is doesn't make sense - why would i want this and how could i stop it from doing this. Please bear in mind i would prefer to use an upgrade disc rather than a full copy to save money.

Full D Recovery Drive Disk Space Warning

I'm having a somewhat similar problem as a previous poster but. Have a newer computer and i upgraded from vista home premium to w7 home premium . My backup d drive is full . I guess the backup has not removed former backups . Now processing is slower and i worried about a total freeze. I used the disk manager and tried to add space onto my d from c but only ended up with an unallocated partition of 20g's .couldn't figure out how to add to d.

In the previous solution " press a special key combination when the computer starts, you can use the recovery partition to restore the computer to the way it was when it was new. " Would that remove windows 7(don't want to do that" or. Do i have to remove the partitions letters for the d? Would that just make it one big c drive? . Would that effect computers performance? How can i get that unallocated partition back to c . Or to d? Sorry for being so wordy but i could sure use some help.

Win 7 Reports Wrong Free Space On Hard Drive

I have 4 partitions set up on my hard drive. 1st partition has my windows 7 installation and some other microsoft products such as the office suit and visual studio and such.

2nd partition is empty and i'm not using it right now
3rd partition i have encrypted with the bitlock and use it for important files
4th partition i use for everything else. This partition is 219 gb in size. I have movie files, music, pictures, software iso's and the program files folder with lots of software.

Total all that data is exactly 48. T gb. I got this number in two different ways both equaling 48. 7 gb: first i manually calculated the sizes of all the folders and then to verify i used a utility called jdiskreport which confirmed my calculation.

The problem is that windows tells me that my 4th partition is completely full and only 1. 3 gb is left when clearly that doesn't make sense. I am missing 160gb which is a large number. I looked at all possibilities: hidden files, system restore files but there's nothing there. I would like to know if anyone out there has any idea as to what's going on and how i can fix it. Absolutely any ideas are welcome.

Usb Drives, External Hd Not Shutting Down

When i finish using my usb thumb drive, or external hard drive and click the icon for "safely remove hardware and eject media" and click "remove", the message pops up saying the drive can be safely removed - but the drive light stays illuminated on the thumb drive or the external drive. If i pull the thumb drive out, the next time i use it i'm informed that there may be errors and i'm given the option to scan and fix the drive or continue without scanning. Because of this problem, i always shut the pc down before removing the external hard drive (its light stays on as well).

Is there some way to correct this?

External Usb Drives Disconnect

Regardless of the usb drive i connect to my desktop pc windows 7 continualy disconnects the drives. I have tested numerous drives, however when tested on my laptop which is using windows 7 ultimate 64 bit all of these exact same drives work perfectly. My desktop is using and intel core2 quad, q6600  2. 4ghz with 3gb of memory. I have read this complaint all over the internet and i have tried several fixes with no positive results. All drivers are up to date. I have uninstalled and reinstalled until i am blue in the face.

From what i have read during my research it appears this is a common problem that 64 bit users are complaining about alot, however this obviously is a problem with the 32 bit windows 7 version as well. Numerous tech sites on the internet are also stating that this is only a problem on desktop pc's and not on laptops, which i guess i confirmed during my tests. Has anyone else experienced this and has anyone found a fix?

Cannot Find External Usb Hdd

I have just bought a new dell inspiron n5010 with windows & 64 bit. However i cannot get it to connect to my maxtor basic 500gb external usb drive. The drive works fine with my other vista laptops and when connected to the dell the light comes one and the drive spins suggesting the drive knows it is connected. The hdd has its own power supply. However nothing shows up on the dell.

Nothing in disk management and nothing in device manager. I have tested all the usb ports on the dell with a flash usb drive and they recognize that no problem. All the ports also recognize a usb mouse. I have raised this with dell who told me to reformat the usb hdd to ntfs (!). Needless to say that made no difference. Anyone got any ideas?

External Usb Hdd Not Recognised By Win 7

External usb hdd not recognized by win 7, and no longer recognized under win xp. Maxtor usb 300gb external hdd working fine on windows xp. Unplugged and attached to new windows 7 pc. Os responds by saying device found and working properly. I use the disk to download assorted files.

Then moved cpu a few feet (did not switch off or move usb hdd). Reboot, and usb hdd not seen as a working disk. Seems very unlikely that hdd damaged at this time. Manage disks shows the disk apparently working but not "initialized". Right click to initialize. Hour glass shows for ~2 seconds, and goes away, but disk not initialized.

Reattach to old win xp computer, and now looks the same as on the win 7 machine, not initialized and not unrealizable.gots lots of data on that hdd which i would like to keep, so have you guys got any new ideas?
