Hi,

 

I have mounted a HDD(Fat32 format - 160 Gb HDD) using following command,

 

"mount /dev/sda1 /mnt/usb -o dmask=0,fmask=0,iocharset=utf8"

 

After few read/ write of files in binary mode, I am getting following error,

 

 

 

FAT: Filesystem panic (dev sda1)

 

invalid access to FAT (entry 0x61726f66)

 

File system has been set read-only

 

I get this issue very rarely and hard to reproduce. Anybody have any insights on this issue.

 

Board: BF527

 

uClinux Package: 2009RC1

 

Thanks in advance,

 

Regards,

 

Jai

What processor, what version of software? Who formatted the drive? (Windows or Linux?)

Robin,

 

I am running it on BF 527 and using 2009RC1.

 

I formated this 160 GB HDD in Windows using a fat32formatter utility.

So, how do you have the hard drive connected? USB or memory interface -- if memory - what else is on the Async bus?

Robin,

 

MSC HDD is  connected to BF527 through Port 1 of USB Controller (Renesas R866597) interfaced on AMS 2 space.

 

Other Async interfaces are NOR flash on AMS0.

 

I am using a custom board with BF 527

It is likely it is a problem with the USB controller driver - I couldn't reproduce the issue when I tried.
