I have a couple of SanDisk 8GB Cruzer Micro USB Flash Drives that don't display consistently in Win 7 Disk Management. They are labeled SANDISK 1 and SANDISK 2. They appear properly as a drive icon with SANDISK 2 drive letter M or SANDISK 1 drive letter K in Win 7 Computer - Devices with Removable Storage, but intermittently appear properly in Win 7 Disk Management. For example, in the Volume list in the top window, I see only an disk icon under volume, nothing under File System, but Layout, Type, Status, Capacity, Free Space and the remainder of the columns appear normal.
Also, in the graphical display in the lower portion of the center section below the Volume list section, the left column appears normal, but the graphical portion to the right only displays 7.50GB, Healthy (Primary Partition), the label and drive letter are not displayed. Also, when I right click the displayed device in the left column, I get a pop-up entitled SanDisk Cruzer USB Device Properties, but when I click the Volumes Tab, I can't select the Volume and click Properties, because only a drive icon and capacity are displayed, the Propertied button is greyed out.
Interestingly, the above description is for when I have only one of the USB devices plugged into the system. When I plug the second USB device into the system, it displays properly without any issues. I don't think it's a device issue, because I can get either to display properly if it's the second USB device attached as indicated in the attached screen shots.
Also, as depicted in the second screen shot, if I unplug the problem device, it will clear from the lower section, but the drive icon and information doesn't clear from the Volume list section. You can see the two icons with missing information, because I plugged the device back in. They are for the same USB device. In this case, SANDISK 2.
Is there a solution to his issue?
Thanks in advance for your assistance.
