One thing needed to know is the OS your running. The sony splash is A: your monitor? B: your bios screen C: a slpash that some videocard's have on them. When the D drive partition is shown on a other computer when the drive is master and boot drive its possible that the boot record of the C: partition is bad. 1st you got to save al you can from the D: part. 2nd you can run defrag on the whole drive when in other PC as an slave drive. But to say and give more advice i realy need more info. At this point there about 1000.000.00 reasons why you got this problem. Chris
