**rthardin** · 10-30-2012

Just purchased used e-studio 452. When powered on, screed said "could not find hdd data." Purchased firmware. Tried 4+9 but screen says "please set correct usb storage device." Any suggestions? Thanks in advance

Need to make sure the USB stick is 2GB or less and formated in FAT, not FAT32 or any other format.

done. 256 and FAT, not FAT32.

I have seen some USB sticks come with a partition that has software on it and this can cause this issue. Have you tried a different stick??

Also make sure the firmware is installed on the stick correctly, you should see a 352_452 folder and a file called mentusb.o in the root dir on the stick, but I suspect your problem is that the original firmware was too low (ie. v010 or v020) which requires a pre-install firmware to get it to v110, you must do this install before any newer version, then I would always go to v232 before upgrading to v355 or whatever is the newest (not sure v232 is required, but has always worked for me). It's been a while but if I'm not mistaken you have to do the pre-install with fat, but the later versions with fat32.

The stick does not have a partition like you said. I wiped it, formatted FAT, put the correct folder and the mentsub.o file. How do I get the older firmware to pre-load? Thanks!
