The driver file details below seems correct and has a date of Bangladesh languages spoken. Checking it out in Device manager and it shows up as this. When the drive is plugged in with laptop switched off windows detects the drive incorrectly as there is no drive letter assigned and it is not visible in Explorer. I am not too concerned about this drive merely the principal of why Windows is either not detecting it at all or incorrectly detecting it. Maybe it is just on the edge of failing as it is about 7 years old and they don’t last forever.

I have a PNY 4GB flash drive which has given me years of service. There are a few other flash drives which work perfectly and they are a mixture of new and older drives. Let me give you a few examples relating to both flash drives and USB connected hard drives I own. I have experienced this issue over the years and am still no closer to a definitive solution. The problem of flash drives that usually show up in Windows suddenly creating a problem by either not being detected properly or at all seems to be fairly well documented on the Internet but there are a plethora of so called solutions which do work for some and not for others. Do you know what the problem might be? Thanks.Platform: Windows 7 Professional (X64) fully up to date with service pack 1 and beyond Could his chip number work for mine even though mine came up as unknown? Also, I saw the advice you gave him was to reformat it, would that prevent me from retrieving the information on my usb stick later? I did go to your links at the bottom and downloaded the pny reformat and recovery software, but the software wouldn't initiate when I clicked on them - they only flashed for a second, and thats it. However, when I did the ChipGenius it came up for chip part number as 'Unknown(?) - 0圎50B - F/W 9505'. I have tried so many different things but they haven't worked, just like Pierre tried to do. I can access properties and info says there is nothing on it. In the process of me trying to fix the problem, when I put the usb stick in, it recognizes it as the 'E: drive' but when I click on it, it says to 'insert a disk into drive E' and when I try to reformat it, it says 'there is no disk in drive E. I have the same PNY 32GB usb stick and I took out my stick at not the best time as guy Pierre did. Is my pend drive busted or am i doing something wrong? The DieSort tool recognize it and after the analysis this is the reportįinally, the last tool recognize it but but the sort stage of the alalysis come to 61.1% the application crashes and windows closes it. I´ve tried the tools on the dowload pack, the first one recognized it once but now it seems invisible to it. This is the info displayed in chip geniusĬhip Part-Number: Unknown(?) - 0圎602 - F/W 8509įlash ID Code: 8988244B - Intel - 2CE/Single Channel -> Total Capacity = 16GB My pny 16gb pend drive stopped working and windows would not recognize it.
