Hardware: A embedded computer system is using Windows xp as an operating system and it has a 40 Gb hard drive, whih has multiple partitions.
Symptom: The hard drive had 3.9 Gb of "missing" memory space on one of the logical drives.
Actions: Removed the hard drive from embedded system, connected hard drive to lap top computer (windows 7) as USB connected auxiliary drive to use lap top operating system to search the embedded system's hard drive for issues. Located a 3.9 Gb error log file which was deleted. Reinstalled hard drive into embedded system.
Result: The embedded system has windows xp operating system could not access the reinstalled hard drive. It saw that it was present but had a size designation of 0Mb. Investigation revealed that the lap top windows 7 had "upgraded" the partition format structure which could no longer be read by embedded system's windows xp. Windows 7 uses a "CHS" for drive partition format structure while windows xp uses an "LBA" drive partition format structure. There was no warning, information, or challenge question of any kind when the drive was installed into the Windows 7 environment.
Remedy: Unsuccessfully attempted to convert the "CHS" back to "LBA" format. Installed new blank hard drive into embedded system and reloaded ghost disk image. So the question is, how can I backwards format the structure of the hard drive without having to resort to clearing the drive.
Or please give me some suggestions on how to troubleshoot this problem so I can provide some more information.
Thanks.
