USB Drive on DVSDK 4.00 - Invalid FAT filesystem

Glenn Wainwright

Moving to DVSDK 4.00, and I'm trying a couple of USB removable drives that worked under 3.00. For both of them, I'm getting a bad media value. Below is an example of the full debug log. Any ideas what might be going wrong here?

Thanks,
Glenn Wainwright

Glenn,

This could mean that the media is corrupt? Can you re-format the media and try mounting it?

Thank you for the response, I appreciate any help you could give. Both of these devices I use frequently to move data to/from the OMAP board (under 3.00). As a test, I reformatted one (double-checking that the format was set to FAT) - unfortunately, it came back with the same result as before: "FAT: invalid media value (0xb9)".

Glenn,

I assume that you have re-formatted the media on a Windows PC. If not can you try your test once again. Further Can you try with a bigger usb media say usb hdd.

Yes, it was formatted using a Windows PC. In the interim, I have also been going around the office here borrowing others' flash drives to see if they work - with the same effect.

However, when I formatted one of my drives as ext3, it was recognized and I am able to browse the filesystem.

I do not have a usb hard drive on hand, but I will inquire with IT to see if any are available. Hopefully, though, the above information might give you some clues.

Thank you,
Glenn Wainwright

I should have a usb hdd to test tomorrow. Any other ideas that I can try out in the meantime?

USB hdd did not work either.

I'm pleased to say that - after trying several other filesystems and going back to FAT again - I discovered that though the kernel claims that it "Can't find a valid FAT filesystem on dev sda.", I can still actually mount the disk and browse the filesystem. It complains every time I do so, but it actually executes all the commands after all and I can read/write to the disk. So, I guess that means this is "solved". Bit odd, though.
