External HD Can't Detecting All Partitions?
Aug 15, 2012
I don't know what happen, but im having problems with my external hard drive. I have 3 partition in it, but only the first one is detecting, the other two doesn't appear at all then a sign pops up saying i have to format it, i hit cancel and all 3 drives disappear. seems like hard drive failure. I have a lot of important data on the other drives, is there any way to recover it myself? I really don't want to pay 500+ dollars to recover the data off the drive.

I installed Windows 7 64-bit on my computer which has only 1 hard drive (640GB). I partitioned it using XP to have 4 partitions: 1) XP Partition 2) Linux Partition 3) Linux Swap 4) Windows 7.The problem is Windows 7 cannot detect any partition besides it's own partition, so I cannot access any of my data from the other partitions (XP and ubuntu --- I don't care about ubuntu but I need the data on the XP partition). I know the other partitions exist since I can access XP still, and I believe XP can detect all 4 partitions.I went to start->menu then searched for partition and selected "Create and format hard disk partitions" and it actually detected all the partitions. The problem was the other partitions did not have drive letters associated with them.So I just right clicked and changed the drive letters.

After having no success doing it manually, I have decided to purchase this program Paragon Migrate to help me move everything onto my shiny new SSD...Now my problem is that my Windows 7 Laptop will not recognise the SSD (I have it plugged into an external enclosure). Very strange as I can access it perfectly fine from my old Win XP machine upstairs..Question being - Is there a reason that windows 7 won't recognise this drive? and what can I do to solve the problem? It's a pain in the ass because I thought that buying that software would be the end to my ongoing upgrade issues

I've just had a new mother board installed in my tower, now it's a Pent 4 3.4g. I used to have my two external HDD's connected to the old system configuration but now at startup, when it gets to Auto-Detecting External HDD's it takes for ever to do anything. I have to unplug them, then do a reboot and all is fine, but then have to plug them back in again.
I know from reading some post's that it's in the BIOS startup sequence but I'm not quite sure where and what to change in the startup.
In the BIOS Boot Device Priority I have: 1st - Floppy Drive, 2nd - [3M-ST3200800AS], 3rd - [ATAPI CD-ROM], 4th - [Disabbled].

I've just experienced my 'external hard drive' not letting me access any data. I put 'external hard drive' in apostrophes, as it's actually an old SATA Internal Hard drive, in an external case.The hard drive was partitioned into two partitions. One about 100GB large which had Windows 7 installed on it, from when I used it inside my desktop. Another which was encrypted with TrueCrypt and was about 800GB large. I tried loading the second partition with Truecrypt, but the computer locked up. In the end I had to turn off the computer manually by the power.I booted up and I couldn't see the hard drives at all - not even in Computer Management. I turned the HD power on and off a couple times and eventually they were viewable - only they'd turned into three partitions, with an extra 24GB partition as the active, primary partition. It might've been that way before but not viewable in My Computer. Now I can see the sizes of the partition in Computer Management, but they show as 0MB in My Computer, as if I'd not formatted them. When I try open them in My Computer though, it lets me open them - it doesn't tell me they need formatting.I'm currently running TestDisk, but it can only see the 24GB partition. how I can recover my data?
Edit: TestDisk Results: No Recoverable Partition Found.Also noticed file system now says RAW.

I work with three kinds of computers. One is on my desktop, new windows 7, dual core, that I use for lesson planning. The second are the computers in the classrooms. I am guessing that they are all almost identical, xp purchased 4 years ago. The third is a server used in the computer lab. I would like to buy an external hd and partition it 3 ways - and install win 7 (english) while it is hooked up to my desktop, install xp (english) while it is hooked up to one of the classroom computers and then install another OS while it is hooked up to the server. I want to be able to connect the hd to the computer, power it on and choose either either partition d:, e: or f: depending on the computer it is hooked up to. I know that I can boot from an external hd but I have never tried putting 3 OS, one to each partition, on an external HD.

I'm having a problem not being able to access 2 out of 3 partitions in an external HD.
Samsung HD753LJ (USB) 700GB
Partition 1: 200 GB / NTFS
Partition 2: 200 GB / NTFS
Partition 3: 300 GB / NTFS
I once had a dual-boot Windows XP Professional SP3 and Windows 7 Professional. Partition 1 could be accessed from both OS, but Windows 7 could not and still cannot 'see' Partitions 2 and 3. While it was still a dual-boot, switching back and forth between the systems was the only way I could access the data in Partitions 2&3 from Windows XP. Now that I have a clean install of Windows 7 only, (stupid me to have forgotten this problem) I cannot access the files at all. I have tried restarting the system, reinstalling the HD driver, replugging the HD, and the problem still persists. What I have managed so far:
> Under 'Device Manager'
>> No warning. All drivers are updated.
> Under 'My Computer'
>> Only Partition 1 is listed and accessible
> Under 'Computer Management' > 'Disk Management'
>> All three partitions are in the disk's table. The 2nd and 3rd partitions are listed with blue bars, total space allocated and no other information. An attempt to get Properties or assign drive letters produces an error message "... Disk Managaement control view is not up-to-date ... ".
> Under 'partdisk'
>> 'list disk' shows correctly sized Disk at 700 GB
>> 'list volume' shows only up to Partition 1 of the external HD.
>> After selecting the external HD, 'list partition' shows all 3 partitions with correct sizes and offsets.
> With MiniTool Partition Wizard Home Edition
Disk 1_______
G: Partition 1
*: Partition 2
*: Partition 3
>> All 3 partitions can be explored (whew ...)
>> The two 'missing' partitions were not hidden.
>> However, when assigning the drive letters to the partitions, the drive letters only stay in front of the partitions' names until I clicked Apply. After which, the asterisks came back again. (I haven't found any way to assign the drive letter in Partition Wizard Bootable CD

I have Asus N55SF laptop, with Windows 7 SP1 64 bit. Also, I have 2 external hard drives. One with USB 3.0, and one USB 2.0. Following problems, I am going to describe below, happen to the both of them. Just to mention, external drives are tested on desktop computer and following problems do not happen.
Let me now describe what happens when I try certain actions:
- When I try to copy large files (10 or more GB) I get an error that destination is no longer visible. External drives disappear from My Computer and I can't do safe remove. But when I copy files using programs FastCopy or TeraCopy everything copies well and drives do not disappear.
- When I try to do Windows Backup and encrypt them using BitLocker drives also disappear, and are not visible within OS.
There is a difference between external hard with USB 3.0 port and the one with 2.0 port:
- When one with 3.0 disappears after described actions I can't see it from Device Manager, I can see it only after windows reboot. USB 3.0 disk connects to one USB 3.0 port on laptop.
- When one with 2.0 port disappears I can see it from Device Manager, and I only have to unplug it, and plug it in again to see it. USB 2.0 disk connects to 2 USB 2.0 ports on laptop.
Common to both disks is that when then disappear from My computer the diode on the external disk cases are still flashing, what probably means that they have some power. Both disk are formated to NTFS, and Allocation unit size is set to: Default. Their removal policy is set to: Better performance (default). On laptop I only have Windows, Office and Asus drivers. Antivirus is: MSE.

Partition 1: OS + programs
Partition 2: home partition for himself
Partition 3: home partition for his mother
Partition 4: home partition for his sister
Partition 5: home partition for his other sister
Partition 6: shared partition for some photos.

Ok, I have run out of ideas on this..My setup is Windows 7 64, P35 chipset, 4g ddr2,Evga 8600GT dual dvi with dvi to vga converter s-video out, Q6600, 160g pata hdd and a Gateway EV700 (17").
I cannot get Windows 7 to show the desktop, or detect the monitor. I have an LCD TV hooked to the S-video connector and that is the only way I can see the desktop.
The main monitor will show everything up to the point of showing the desktop..that is where the mon goes blank and I have to look at the TV.
Someone suggested I try XP driver for the monitor, but it will not install and just gives a dialog saying that winxp and above already has the drivers nessesary.
I have tried the Windows 7 64 drivers from MS update, Nvidia, and EVGA (both Windows 7 and Vista 64 drivers).
I have tried both monitor outputs. nothing.
I have a KVM which was not an issue for XP, but I am not sure about Windows 7.
Taking out the KVM is my last resort, as I am running out of ideas.
I also tried using an old Diamond Stealth PCI card to no avail....It wouldn't even post with it.
If I had a VGA to S-video converter, I would try that, but for now, I am stuck trying to use Windows 7 on a tv screen that is only 12".
At 1024x768 it's not much fun trying to read anything on it.
I forgot to add that the Nvidia ctrl panel does not show multi display menu.

Recently i upgraded win XP to win 7 with a format and fresh install. Though after the install, Win 7 did not pick up my onboard sound card or my usb modem. I have the drivers for them but how can i install them if Win 7 wont pick them up? they dont appear in the device manager at all. Win XP had no problem at all with this. Is it possible that they hardware is to old to be recognised by windows 7? i dont have the XP software to switch back so hopefully ill be able to fix this with assistance.

My brother was trying to restore his friends laptop and during the process the power got disconnected and the C Drive got wiped--I believe. I decided to fix it I would do a fresh install of Windows 7.
Everything was going great and I got the recovery disk to install, but my problem was the Hard drive wasn't showing up as unallocated disk space. The drive did show up, but not as any free space. I tried to do some tutorials in diskpart to fix the drive, but to no avail.
Now, I can't even get windows, or BIOS to detect the drive. The last diskpart command I did was to reformat it. It wasn't the quick reformat, but the one that takes an extremely long time. That's when I noticed it wasn't detecting anymore.
Here's some pics of what I'm seeing:

I've lost all my usb drivers and windows will not connect or recognize any usb device when I install it. Here's the message I get from device manager:Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39). I've tried everything possible to correct the situation even reloading the intel chipset from Asus web site. Windows no longer will detect a flash drive or external usb drive. I'm at the end of my rope and I don't envy the thoughts of a reinstall. Is there a way to reinstall the usb drivers?Any one can point me in a direction.

I run a Nvidia GTX 275 Works flawlessly even if i use both ports on the back to use dual monitors.
If however i plug my Nvidia 8800GT in the second PCI-E x16 Slot the computer only recognizes the 8800GT which is in the second port and there is no GTX 275 showing in the Device Manager or Boot Menu.
So basically i plug in my second video card and my primary card just vanishes from the computer like its not even there.
Has anyone got an idea what could be the cause of this?
I have checked the drivers and its the same drivers at the moment for the 8800GT and the GTX 275.
I want to be able to run my 19" Widescreen Monitor on my GTX 275 and use my 8800GT Card for my tiny 15" Screen so i can play Games on my Primary card and be able to have Website open and viewable all the same.
(I'm not trying to run SLi as i know you need 2 of the same GPU and your motherboard needs to be able to support it, I don't like SLi so its all good so far.)

I'm trying to plug a USB camera into the back of my computer, but the computer won't acknowledge that I plugged it in. I don't get an error message or anything, it simply doesn't seem to notice anything. (I've tried it with a flash drive, too—same deal.)
I'm not missing drivers for the device itself, as I've plugged them both into other ports and they work fine. It seems that the port itself is the problem. I just reinstalled Windows yesterday after getting infected with a System Fix virus, so that may have something to do with it.
EDIT: It may have something to do with my BIOS, as I changed my boot order for the reinstall. I'm not aware of anything else being changed, but it's possible.

I no longer can stream media from my PC to my PS3. It used to work a couple of months ago and it still works with my dads computer. Both mine and my dads PC are windows 7. I've compared the settings between the two PC's and could see no difference. I've tried several different media server programs including vuze, ps3 media server and windows media player and none of them work.
I've made sure all the media streaming and advanced sharing settings are correct and the proper services are started and temporarily disabled windows firewall. As far as I can see its an underlining issue and not one on the surface.
