I just bought a 'cheap' (which may indeed be the problem) 128GB flash/zip drive. Generic. In attempt to access the drive windows prompts me to format the drive first, yet is unable to do so. I have tried exfAT32 and NTFS to no avail. The Window states, "Windows was unable to complete the format". It shows up under 'Computer' yet properties shows 0 bytes used and 0 bytes free. Can anyone help me here? Lotsa thanks to any advice!
Windows 7 doesn't see 128GB flash drive
- Thread starter 20725
- Start date
Try the following procedure (copied from here) -
Open Command Prompt with admin rights.
*Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.
Or
*Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.
As I was on an Admin account already I just hit Start key + R. Then type in cmd.
First type DISKPART and hit enter. You will see a text block saying version number. Takes a second depending on number of drives.
Next type LIST DISK command and note down the Disk number of your USB flash drive. it will be listed as disk 0, disk 1, and so on. My thumb drive was Disk 4 with my other four drives before it. You can also see the total size as well as free space for each drive. Here my Thumb drive was ** bytes, 0 Bytes free. While the windows manager displayed a 0 bytes, 0 free.
Replace the drive number “#” with the correct drive number for the following commands.
SELECT DISK #
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
(here you put the file type you wish to format in to. NTFS, FAT32, FAT16. FAT32 is standard.)
FORMAT FS=NTFS
(Format process will take a few seconds)
ASSIGN
EXIT
If the above doesn't work, look at some of the other suggestions in the above link.
