I can not get my SanDisk Cruzer Glide 16GB or 64GB to work on my HP DV6 Laptop with Windows 7. The same flash drives work in two other computer I have tried them, but NOT in my HP Laptop. When I plug them in it take about 60+ seconds before they appear in the “My Computer” display. If I double click on the “Removable Disk Icon (I:)”, after about 60+ seconds, as a gray bar moves across the second line at the top, “This Folder is Empty” finally displays. If I Click “New Folder” an error comes up stating “Item Not Found”, “Could not find this item”, “This is no longer located in Computer, Verify the item’s location and try again”. It appears about like a DVD drive with no disk inserted.
Disk Management shows a Removable Disk at I: with “No Media”.
Again these Flash Drives work fine on other computers, and do contain files.
My other 16GB flash drive (not SanDisk) works fine on the same computer.
SD card reader with SanDisk SDHC cards work fine in the same USN ports.
Does anyone know what I need to do to fix this problem?
12-04-2012 Additional Information
I found out today, that if either of my SanDisk Flash drives (16GB or 64GB) are plugged into the USB port BEFORE I start up the computer from a total shut down they come up in a totally normal readable state. I can read or write to the flash drives with no problem. However, if I Eject / Safely Remove the flash drive, then reinsert the flash drive the state is in the unusable form as described in the paragraphs at the top.
If instead of doing a complete shut down I only do a Restart the flash drive stays in the unread / unusable state as described in the first paragraphs.
A complete power up from a full shut down, with the flash drive already in the USB port, is the ONLY way I have been able to get the SanDisk Flash Drive in a usable state on my Windows 7 64 bit HP DV6 Laptop.
I thought the 16GB flash drive had worked on this computer in previous weeks, but I can’t swear to it. The 64GB flash drive was a Black Friday purchase, so wasn’t tried earlier.
