Question

USB drive not showing in "My COmputer" but found under disk management

Asked by: d_melnyk

Hi folks:

   I have a USB 250 GB HD that was "initialized and formatted" under Windows XP Pro (SP2). The system is using system commander to allow for dual booting. When I boot to another version of XP also XP PRO SP2, the usb drive is not found under my computer, although it does show up as a disk under Disk management but with a comment that the partition is unknown. There is no option to "initialize" the disk - i.e. it is greyed out. When the drive is plugged in (or out) XP plays the appropriate "Beep" noise indicating a USB device has been plugged in, but nothing shows up.

Anybody have any ideas as to how to solve this issue?

Best regards, Dave Melnyk

Try deleting the USB driver in device manager and let it re-install on reboot.

one option is to plugin ur usb drive in some other computer and try to format it first and then make partitions on it, after performing these task plug it back in ur own computer with XP pro SP2 i guess this will help u.
d_melnyk can u tell me if u are plugging both cables of usb drive(i.e one for data transfer and one for power) in computer or not, because the most of the usb HD
cases have two inputs one for power and other for data, and both inputs are usb based.

You can also change the Drive Letter of USB, it could be possible that same drive letter is assigned to other local or network drive, which is conflicting with USB Drive. You can go to Control Panel > Administrative Tools > Computer Management > Disk Management Check the USB Drive what is assigned or might be not assigned (Please insert the USB Device in Computer).

Please change a drive which you will never use or have used before.

Also if you have many other ports try switching USB drive in that.

Kamlesh

Hi guys, sorry i did not respond earlier - few problems over the weekend and then an exploding UPS!

I tried deleting the USB driver - and then rebooting - it finds and installs the driver and finds the drive - but the drive is listed under disk management as "Unknown partition - Healthy" - the only available option is to "Delete" the partition - which I do not wnat to do as I have data on it that I require.

I cannot change the drive letter as that is not an available option. The drive is listed as "Online".

I do not have any wierd drivers installed - like "sptd.sys".

I have partitioned and formatted the drive under this system and it seemed to be working fine until a reboot - when it could not find the drive again.

Any other options?

Thanks in advance - Dave Melnyk

Hi kamleshgwalani:

   Thanks for the reply - unfortunately the only options available are "properties & Help" - "convert to dynamic disk" is greyed out and that is the only choice.

Could the problem be because this disk was made a primary partition initially?

Regards, Dave

Do you have the same user set up on both OS'es?  If you boot to the OS where you initialized the drive, is it visible?

 

by: kamleshgwalaniPosted on 2006-09-08 at 00:38:55ID: 17477553

In that case you do the following or may be try out :

* Try plugging this in some other PC / laptop. If it works then it could be driver problem. if doesnt work in other system, then hardware fault could be also a reason behind that.
* Check the updated drivers for the hardware drive from its manufacturer website.
* You can convert it to dymanic disk and see if the above doesnt work at all.

Regards
Kamlesh
