This is a great idea.

Can I use seek on a raw device? The problem we run into if we're going to read the whole device, of course, is that the system (burly as it may be) does not have 4.5gb of ram, and 3.5gb of swap is unweildy. So we can't just slurp the whole disk in and checksum it... I was thinking that if we can read in the first gig and the last gig and provide two checksums, we can be reasonably assured that the middle 2.5 gig are okay.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
