DSO Quad 2.7 error reading BMP images

Hi all!

DSO Quad 2.70 has original SYS Ver 1.52 and APP (PLUS A1) Ver 1.00 firmware

1- Saved some BMP images
2- Attempt to move them to Windows 7 notebook with Error 0x80070570: The file or directory is corrupted and unreadable.
3- Formatted USB MINIDSO
4- Rebooted DSO
5- Saved 3 BMP images
6- Thumbnails in windows explorer are all ok
7- Same error as before on IMAG001.BMP and IMAG002.BMP; IMAG003.BMP copyed ok
8- Mounted on linux box
9- Copying in linux brings up error FAT: Filesystem panic (dev sdb) - fat_get_cluster: invalid cluster chain (i_pos 515) on IMAG001.BMP and IMAG002.BMP; IMAG003.BMP copyed ok
10- Saved IMAG004.bmp - Not readable in windows platform
11- Rebooted DSO - Now IMAG004.bmp is readable but parameter file not found.

Would there be anyone willing to try the steps above or is this a reported bug?

Thanks
