hi guys iv just bought a 64GB USB flash drive mainly to use for a bootable usb for installing win7/8.1...a bit overkill i know. it came formatted with exFAT and im finding impossible to format to FAT32 OF NTFS. every software iv tried to use to make a bootable 7/8.1 usb fails. am i missing the ovios??.any help will be great.
Does the usb stick comes with flash memory with software from the manufactory perhaps ? Sandisk has such usb sticks and you only can format trough the software implanted on the stick itself !!
tried it this mourning. says its done but stops responding. probably explains why i get a error with diskpart "virtual disk service error the volume size is too big" when formatting to FAT32. also i get "diskpart has encountered an error the parameter is incorrect" when formatting to ntsf. no idea whats going on
For "write protected", sizing or partition type errors, I've had good results with the HPUSBFW app. It's free. I can't recall if you need to run it elevated/system admin, but I would anyway. And after you run it, I think you need to disconnect and reconnect the flash drive before using it again.
Wipe the flash with diskpart clean all command and then create a new partition, format from diskpart too, if it errors you have a bad flash. diskpart> sel dis x (where x is the flash memory) diskpart> clean all diskpart> create partition primary diskpart> format fs=fat32 quick or fs=ntfs quick (depending what you need) diskpart> assign diskpart> exit
That's a myth only. The limitation of some old win9x software, probably fdisk itself. The real limit is 2TiB if you have a sector size of 512 bytes and it can grow as large as 16TiB if you have a 4096 bytes large sector size. Go ahead and try it in a virtual machine, even good old pqmagic is able to create larger fat32 partitions, not to mention today's more advanced software.
exFAT should be bootable for win8, just like FAT32. And you can have files larger than 4 GB - the FAT32 limit. Same instructions like FAT32 above, remember diskpart -> active - make partition Active When the exFAT USB boots, it will slowly say 'e x F A T' on the screen
well iv tryed all the diskpart commands but with the same errors i previously posted. after i attempt to format anything other than exFAT it seems to screw things up...everthing stops responding for ages. the usb could be faulty but once im back to exFAT everthings fine. are you saying use diskpart but substitute fat/fat32/ntsf/ for exFAT then copy the win files onto the usb??
I would go back to the store with a usb stick that works like the one you have And BTW try to convert to ntfs maybe that works
i would but i got it about a month ago. put it in to check it and because it opened up i thought it was ok. so i dumped the packaging ......didt think of trying to fomat it to ntfs. read my first post.........
I would try to clean the drive with RMPrepUSB and then use Easy2Boot to create the installation disk. Go to the Easy2Boot site for details.
