Browse All TopicsLast week I added a WD20eads 2T hard drive to my HP m8200n that was running Vista Home Premium. It seemed to install correctly, was seen in set up, device manager, etc. But then the PC lost files that I saved to the new 2 T HD. Chkdsk found the files again and reindexed them. The second time this happened I decided to start over with a new install of Vista Ultimate on a new WD 1T HD. After this install, I added the 2T HD. The new OS recognized only one of the two partitions on that 2 T drive. Boot dialogue reported one partition (F:) "file system clean". But for the other (G:) the message was "file type is NTFS. Unable to determine Volume version and state. Chkdsk aborted". Disk management saw G: as a raw partition. Here's the weird part. When I set up the PC again with the old HD that has its old Vista Home premium OS it reads the G:partition without problems. Where would you start to troubleshoot this? The 2T drive has the data files I want to transfer to the new Vista Ultimate 1T drive. Thanks. Olivia

1. Re bios:
A) I have the highest bios recommended by HP. There is a later bios for my motherboard, but this group has suggested that my motherboard might have been customized by HP, and that the later bios might make my computer inoperable.
B) This 2T disk works right now on the same computer with the same bios(I checked). I merely switched back my C drives and it still works. The New 1T main disc is the same WD model as the one that is working now. The Big difference is that the new drive has a new Vista ultimate OS and a bunch of updated drivers while the older drive has an older install of Viista Home Premium, but should that matter?
2. Re GPT:
The article says "You can convert an MBR disk to a GPT disk and vice versa only if the disk is empty." I have 638 gigs of data on that drive that I need, so I'd sure like to find a work around. The article also says "MBR disk partitioning style supports volumes UP TO 2 terabytes in size, which may mean I am pushing the limit (at 2T). But why can I see one partition (the one that is almost empty) and not the other. Should I try to move half of that data to the readable partition? Should I decrease partition sizes and leave more unallocated? (w Acronis Disk Director?) I could make that change while attached to the old C drive... Thanks. Olivia
WD seems to say that the 2T limit is per partition, not per disk. See http://wdc.custhelp.com/cg
here a easier fix.
Try getting a sata to usb adapter and transfter the data this way. http://www.cooldrives.com/
