Problem using exfat drives for backup

Topic

New Reply

I have 3 (cheap) external drive with the exfat format I got to use as backups. The problem is the image file always checks bad and I can’t use it.  I can use a drive with a ntsf format and no problem.  I also have several flash drives with the exfat format that I can’t make a rescue usb with  but again works with other formats.  Any ideas as to what’s up with the exfat format?  I did also try on two different computers with same problem.  This is on windows 11 computers.

Pros and Cons of File Systems used with Internal and External Drives

I read through the pros and cons of filesystems about two years ago when I was having no end of problems getting a USB drive to boot into Ventoy.

I reformatted as NTFS, rather than exFAT… and haven’t had any further issues.

Hope this helps…

Do NOT use cheap drives for backup. As you have discovered, this may not produce a “backup”.

Spend money on a standard USB HDD and use that as the backup destination. You can store multiple backups on one drive.

cheers, Paul

p.s. I would test your drives with GRC Validrive to see what you actually have – this will not be fast.
