My [URL=http://www.sony.net/Products/Media/Microvault/usm-e.html]Sony USB 2.0 Micro Vault Flash Drive Storage Media, model no. USM-256EV[/URL], also called a [URL=http://www.sony.com.my/sonystyle/cat_accs/micro_vault.asp]Sony Micro Vault ELITE,[/URL] cannot be seen by my windows xp professional sp2 operating system in "my computer." I have tried SONY's Trouble Shooting page and read SONY's FAQ, Knowledge Base Articles 325653 and 318654 and Notes on use for the 256E, but so far nothing works.
The [URL=http://www.sony.net/Products/Media/Microvault/download_usm-e.html]SONY formater[/URL] will not recognize that my SONY USM-256EV flash drive is connected; and neither EZRecover 3.0 for PL-2515 nor EzRecover_Stormblue recognize that it is connected. Nevertheless, my SONY USM-256EV flash drive shows up under "device manager," is detected by [URL=http://www.lavalys.com/]EVEREST 1.51[/URL] and the folders & files written on my SONY USM-256EV flash drive by another computer which using a windows 2000 OS can be recovered by [URL=http://www.active-undelete.com/]Active Undelete[/URL] on my windows xp computer.
I clearly cannot write to my SONY USM-256EV flash drive from my windows xp computer (although at one time I could . . . I have no clue what happened, if anything, to make it quit), because it is not recognized as a disk drive by "my computer" in windows xp. The Windows 2000 computer can both read and write on my SONY USM-256EV flash drive.
Using a flash light, and looking at an angle on the middle translucent part my SONY USM-256EV flash drive, the controller chip is identified as a [URL=http://www.ktc.com.tw/download.asp]KTC-FC1325N USB Flash Drive Controller[/URL] manufactured by [URL=http://www.ktc.com.tw/about.asp]Key Technology Corporation[/URL] out of Taiwan.
The flash drive came with the following software: Password Lock, Auto Zip, Auto Login and PC Lock, and includes drivers for Windows 98/98SE, but I have not installed any of this software (I do not want to make the problem worse than it is).
I sure would like to be able to read and write on this flash drive with my windows xp as well as my windows 2000 (located at the office). Now . . . although I can bring files home, I cannot work on them at home and then take them back to the office. It is a one-way street, and the only off-ramp at home is by using Active Undelete to locate the files and folders on my SONY USM-256EV flash drive, recover and copy them to my C drive at home.
Windows 2000 installs driver version 5.0.2183.1 for my SONY USM-256EV flash drive and windows xp uses driver version 5.1.2535. It does not appear that my windows xp will permit me to install 5.0.2183.1 drivers.
Both Active Undelete and EVEREST 1.51 report that my SONY USM-256EV flash drive uses a FAT16 file system. Active Undelete reads a serial number of E4DE-3250 on the flash drive but there is also a number D33021 which appears on the outside of the SONY USM-256EV case.
I AM STUCK and have no clue whether this is an original SONY product, a FAKE SONY product or, and more to the point, if I can every get the thing working on both computers again. I would appreciate any help. Thanks,
Sojourner.
