The desired sectors are beyond the last full cylinder on disk. Not being within any filesystem, ordinary file viewers wouldn't be able to find them even if part of a file.
That is nonsensical. If the data in question is "part of a file" then by definition it's within a file system.
Yup. Been an intense day. Time to wrap.
As dmraid data, I didn't expect them to be within any file anyway. Formatting is a non-issue.
You asked for a "hex dump." That's data formatting.
To me hex dump just means looking at a sector's contents, typically hex gobbledegook unless formatted for human consumption.
Nonetheless, when using a raw device, such as /dev/hda, you are not subject to the boundaries of a file system or of the partioning of the device, only of its total capacity.
That's why I was looking via dd. Anyway, I finally got enough hang of the dmraid command to get what I wanted. 'dmraid -r /dev/sda' told me the size that hpt37x considers the device to be, and the location of the dmraid data - 10th sector of the first disk track. 'dmraid -D -r /dev/sda' created three files, one of which was a copy of disk sector 10. 'dmraid -E -r /dev/sda' filled sector 10 with nulls. RAID gone. Time for sleep.
