On some occasions, when powering up, the Zip stalls and above the Rockbox logo there is a ATA Error -1, then after a few seconds it turns off. Powering on again, it seems to work ok, until the next boot.
Sometimes also, the ZIP just stalls, and I have to hold the power key down for 20 seconds or so, then it turns off.
Any help here is appreciated. Using Rockbox 3.13
