Brief synopsis; Three 652's, all used. #1 & #3 with stock 160GB drives. #1 was upped to a 500GB. #2 has a 2TB drive. No original. #1 & 3 no problem. The first was dome with MFSLive, #3 was done with WinMFS. I was concerned about Windows 'seeing' the drive, then writing to it, so I stayed safe and did it in DOS. I re-read further the documents I found on the subject(s) and decided to try WinMFS. This is with a XP Pro PC drives connected directly to a SATA bus, no USB adapter. I encountered this error when trying to swap a 2TB for a 1TB HDD in a "HD model 652": I'm using MFS V1.4 The drive being imaged is a 2TB taken out of a model 652 (HD). The destination HDD is a 1TB HDD which was never installed. Ythe 2TB will go in another 652 later. I have done this before (successfully) with the same boot CD. From what I have read on this, it seems it's something that happens inside the O/S, not from a boot CD. Does the source or the destination drive have anything to do with this? Is a 2TB drive a problem here?
