Mac format fat32 command line

Windows 7 Professional bit: John, does your computer recognize the drive when it's connected? It sounds like the drive is broken to begin with. Did you try any of the tools? Tina, nope. The first basic advice just doesn't work. The cmdline tool starts the process, it's true, but ends up with a "volume is too big for FAT32", even with a 64GB.

Please correct. The method worked fine on Windows 7 back when I wrote the article in If it no longer works, I recommend using one of the third-party tools. The article above is your guide. I would try this tool: Downloaded the FAT32 utility, which promptly formatted the drive in 10 seconds. Hope future visitors see this! This does not work.

It is true that Windows won't mark "weak" sectors, however this is not guaranteed using any other "proper" software for the job either. I haven't used them in a while but SeaTools used to have problem with those sectors too. If the sector was found weak and the data couldn't be read and relocated it would be marked as pending until [any] data was written to it again. I would rather use Check Disk than some third party software simply because in addition to mark bad sectors it is able to detect File System errors.

Unless the tool is able to do that it would just relocated the same bad data. All drives nowadays come pre-formatted.

The only reason to re-format is because you want to have another file-system. Using the format tool to determine whether the drive has bad sector or not is very unreliable it does not even check if the written sectors can be read and also only writes zero-bytes. If you are in doubt your drive is still OK you should really use the manufacturers test tools. Those work much more reliable and are also able to properly mark the sectors as bad. Doing a quick format on a brand new drive is asking for trouble because it doesn't actually verify that all the sectors can be written to.

Yes, formatting a 1 TB drive can take a while, but it's less time than doing a quick format and having to recover your lost data when you find out the drive is bad. Also pretty much all digital cameras use FAT32 on their memory cards.
