    Hi,

    I have a problem with my 500GB SATA HDD.

    I was using it as secondary internal HDD in a Win XP system, and it was partitioned into 3 partitions (200GB + 150GB + ~150GB).

    When I attached it externally to a Win 7 system, it didn't show up in My Computer. It was labeled in Disk Management as dynamic disk. I used the method shown in the following link to change its state:
    https://www.wilderssecurity.com/showthread.php?t=191006
    by changing the 1C2 location from 42 to 07, and rebooted my system.
    After that in Disk Management it shows me a healthy primary 500GB partition (just one partition). The explorer shows only the first partition (200GB) and doesn't show the other two.

    I have really important non-backed up data in the remaining two partitions, and don't want to lose them.. Does anybody know a way to show the other partitions without losing my data?

    Thanks in advance.

    selo,

    Can you make a BootIt BM CD and let us know what you see in Partition Work?

    Download BootIt BM. There is a 30 day trial usage. Unzip the file and make a boot CD.

    double click makedisk.exe, next
    dot in BootIt Bare Metal, next
    dot in I accept the agreement, next
    don't select Image for DOS (GUI), next
    dot in Mouse Support Enabled, next
    dot in VESA Video, next
    dot in Video Mode 1024*768 - 64K Colors, next
    dot in Partition Work (Don't put a dot in Normal), next
    don't choose any Device Options, next
    tick in Enable USB 1.1 (UHCI), next
    tick in Align partitions on 2048 Sectors, next
    ignore Additional bootitbm.ini Options, next
    select your CD burner drive letter (you can use a CD-RW or a CD-R disc)
    Finish

    1. partitions on your HDD maybe cross-linked.
    2. your HDD is identified as a wrong dynamic disk, because of the '42' partition type

    my suggestions:
    1. change '42' back to '7' to recovery your first primary partition
    2. google a disk/partition management freeware to recovery the other two partitions. most of this kind of freeware usually have the ability to recovery lost partitions.

    caution:
    to avoid damage your important data, you should double check the partitions found before applying the recovery
