1361907 2013-12-06 02:54:00 Here is an odd one.
I have a 2gb flash drive which has decided not to show up in a win7 system.
Makes the sound when plugged in but dosent show up in Computer.
Shows in disk managment as offline.
Tried font & rear usb slots, same.
Works fine in other systems, Vista & Linux.
Other flash drives work ok in the win7 system.
Have reformated it & even gave it a workout in Easeus Partition Manager.
Am I missing something obvious here?

1361908 2013-12-06 04:57:00 If it works fine on other systems there is probably some problem with the system it doesn't work on. Check for higher than normal USB voltage (should be 5v) or noise. Could be your PSU 5vSB rail is failing. Agent_24 (57)
1361909 2013-12-06 05:11:00 I have had the very problem you speak of and it applies only to Windows7, it is well known and plenty of stuff on the web if you google Win7 won't show flash drive.

You need to give the drive a name in Windows Drive Management.

1361910 2013-12-06 07:04:00 It's only that drive that won't work on the win7 system.
Everything else I plug in does.

1361911 2013-12-06 07:06:00 Can't get in to change the drive letter.
It comes up as off line.

1361912 2013-12-06 07:35:00 Try the 2nd post (en.kioskea.net) Speedy Gonzales (78)
1361913 2013-12-06 07:41:00 No.
Are you referring to a previous problem I had?

1361914 2013-12-06 07:42:00 Oh ok. well the 2nd post above may fix it, using diskpart

1. Click Start and type Diskpart in the search box.
2. Right-click diskpart in the search results > click Run as administrator.
3. Once diskpart loads type list volume, press enter.
4. You should notice that you will see your 2 TB Western Digital Hard Drive, it should not show a drive letter assigned to it. <- in your case, the flash drive
5. Type select volume 1 (replace 1 with the volume number assigned to the Hard Drive in question). <- in your case, the flash drive
6. Type assign letter Z (replace Z with the letter that you want to assign to it).

"I found I could right-click the "Offline" notation and choose Online from the menu that appeared"

1361916 2013-12-06 09:17:00 Just tried the Diskpart method with the suspect flash drive.
Drive was not shown.
Tried again with another known to be good flash drive.
No problem, showed up as it should as the next numbered drive.

In disk management, the only place it does show up, as "Disk 1 Removable" offline.
Hovering the mouse over brings up (The reason the disk is offline cannot be determined)
R mouse shows the online as greyed out.

Personally I think the fault is with that particular flash drive.

On the other hand the win7 is a gaming system which rarely goes on-line & has been tweaked a bit.
It's also mildly overclocked & does throw a wobbly occcasionally.
