A customer brought an Ativa 4gb usb flash drive that does not recognize. It attempts to install the driver, but fails on Windows 7 and XP Pro. Linux does not see the drive, so I cannot attempt to mount.

Windows does recognize there is a drive in the usb port, but that's as far as it goes. Device Manager assigns a drive letter, D:, but it says the port is empty.

I have tried Data Extractor and GDB, but neither finds the drive.

R-Studio sees the device generically with the following specs:
Device/Disk: UFDUSB Flash Drive1100
FS: #3 USB(98:232)

Properties:
Drive Type: Physical Drive, Disk
Name: UFDUSB Flash Drive1100
OS Object: \\.\PhysicalDrive3
R-Studio Driver: WinNT\Handle\Physical
Size: -1 Bytes
Sector Size: 512 Bytes
I/O Tries: Default

Drive Control
Maximum Transfer: 32 KB
I/O Unit: 512 Bytes
Buffer Alignment: 4 KB

Device Identification:
Vendor: UFD
Product: USB Flash Drive
Firmware: 1100
Bus Type: USB

Am I overlooking something logical?

All that is being recognized it the usb controller, and not the data chip.

There is probably not much more you can do besides testing the circuit board components , like resistors.

The flash chip will most likely need to come off and read into a flash recovery machine.

If you do not have the appropriate hardware to do this. (PC-3000 SSD edition, or soft- center) then I would outsource it to a DR company that can do that.

Good Luck

Cleanroom is correct.

The device appears to have a problem, which will require the chip removing and decoding.
