WARNING: uLE v4.31 writes corruptly to USB drives !!!
Like the title says, using uLE v4.31 to write any files (or to delete any) on a USB drive may cause corruption in the FAT32 filesystem of that drive. And for large files this is almost certain to happen.
Please avoid using uLE v4.31 to write on USB drives.
If you must write to such drives on the PS2, use uLE v4.30 instead, since that is not affected by this problem.
The problem is caused by some bug(s) in the new USBHDFSD driver version which was used for the first time in uLE v4.31. I will be working with radad, the developer of that USBHDFSD version, to fix this bug ASAP.
