Is to make one big NTFS partition on the drive using nothing but Microsoft's drive/disk management tools. I've seen your issue but the person was tinkering with partition tools other than MSFT so no one could say what was going on. They were upset over having to go with one partition and not using their choice of partition tools.
A 72.8GB exFat/160GB NTFS partitioned Western Digital WD2500 BEV shows up on the computer I created the partitions in with both partitions present, but on a home laptop, it only shows the exFAT32 partition. On the PC at work, only the NTFS partition shows up and on the laptop at work, only the exFAT shows up.
The comptuer I made the partions in is a standard issue desktop, only it's running Windows 7. The home laptop also runs Windows 7. The PC at work runs XP SP2 and the laptop runs XP SP3.
I created the partition with the W7 PC at home after I began experiencing this issue with the same drive, which had been formated on an XP box at TAFE. Bearing in mind that this issue was not always present... for a while, the disk showed both partitions to all machines.
So I reformated it on the W7 PC and reversed the order of the partitions. Still the problem persists.
I've been searching the net and forums, but I'm yet to find anything of use. Has anyone heard of this issue? Have any ideas on where I can go for a solution or maybe you've dealt with this yourself?
