Boy, is that weird! Are you sure it's the drive and not something about your laptop? If you want, you can try breaking that 1024-byte block up into smaller pieces. Like just the first 512 bytes, or just the last 512. Or 512 taken from somewhere in the middle. Then break that down to 256 data bytes plus 256 0's (writes are always done in multiples of 512 bytes). See if you can find the minimal byte sequence that causes the lock-up. Of course, even once we know what the minimal sequence is, we won't know why it behaves that way or how to get around the problem. But at least it's a start.
