I had a problem, my thumbdrive was working fine last few months. I had transferred files into my thumbdrive, i had tested it by rechecking is it being transferred into it. Its was there but recently i insert my thumbdrive again, it cannot be detected and i totally cannot access files inside as its not even detected. Is there any way i can get the files inside the thumbdrive? Help help help.....
=(
ps: insert thumbdrive have light on the thumbdrive but its not detected.

Have you tried another computer?

Cannot be detected. You mean operating system doesn't notify you when it's inserted ? What operating system ?
So it's not visible in "Windows Explorer", "My Computer", or "Disk Management" ?
-
Yeah, i tried on alot of computers.
OS is XP, last time my OS will notify me but after few months later it doesnt... yup, its not visible... .
-
"Disk Management" ?
Your sure you tried this ? ?
-
Disk Management. If possible, view the thumb drive's disk structure within Disk Management to see how it's reported.
a. Disk(s)
o CD - represents system partition for U3 enabled thumb drive
o Disk - Fixed or Removable ? (Data partition for U3 enabled thumb drive)
b. Structure of Disk
o Partitions - Number and type (e.g. primary, extended, logical)
o File System(s) (e.g. Raw, FAT, FAT32, NTFS)
o Status - Healthy or ?
o Capacity - in MegaBytes (MB) or GigaBytes (GB)
o Free Space - in MB or GB
o Unallocated space on drive (how much, if any)
To access within Windows XP:
o select "Start" ->
o right-click "My Computer" ->
o select "Manage" ->
o within "Storage" category on left pane of "Computer Management" window, select "Disk Management".
Look for information in both the top right-hand pane and the bottom right-hand panes of Computer Management window.
2. USBView. This is a utility provided within the Microsoft "Debugging Tools for Windows" package. It should indicate whether the device has connected and is recognized (I believe it at least reports the information from the device necessary to support "Plug and Play".) From the help file provided within this package:
USBView can enumerate USB host controllers, USB hubs, and attached USB devices. It can also query information about the devices from the registry and through USB requests to the devices.
Download and install the appropriate version of "Debugging Tools for Windows" (either 32-bit or 64-bit). You should find the "usbview.exe" file in its installation directory, e.g. "C:\Program Files\Debugging Tools for Windows (x86)". Double click on the executable to run it.
Here is a link to the 32-bit versions: Install Debugging Tools for Windows 32-bit Version (http://www.microsoft.com/whdc/devtools/debugging/installx86.Mspx).

Yes. I am sure Disk management because i had done it. Its not visible, not detected....

Yeah, i used the usbview already dahlar.. its still not being detected...... =(

1. USB Thumbdrive Access. At this point I'd guess either:
o USB thumbdrive hardware/firmware/software issue
o USB subsystem hardware/firmware/software issue
o Resource configuration issue (IRQ conflict)
o Insufficient power to port
2. USBView. If the thumbdrive is not "detected" by USBView, you won't be reading any data off the drive in its current configuration. I would have thought if the drive is plugged in and lights up, that the USB subsystem would detect something (but haven't found much documentation on use of USBView).
So you've examined the USBView displays and verified that you can map every used port to a "known" working USB device. There are no "used" ports that might be the troublesome thumbdrive?
If USBView doesn't detect your thumbdrive, either the thumbdrive hardware is bad; or there's a problem with the computer's USB subsystem, resource allocation, or power distribution to ports.
Does USBView successfully detect any USB devices on your system? What USB devices, if any, are you using on that system?
3. USB subsystem. If possible, attempt to use a known working thumbdrive with same (or greater) power requirement in the port you've been trying. Does USBView detect it and display its properties? Successful detection of this device would suggest the original thumbdrive is broken/dead (hardware failure).
4. Device Manager. Any "unknown" devices flagged in Microsoft Windows Device Manager utility?
-
I suggest starting with point 4.

Hey guys, i had tried number 4 solution and its not detected. Have light but cant detect. If its hardware failure, is there any way i can retrieve the datas inside? i had important datas inside... =(

...i had tried number 4 solution and its not detected....
"number 4" asks a question which you did not answer.
