+description = """Error: "SSD Read Error"
+
+Something about the contents of the disk causes qemu to wildly misdetect the disk geometry.
+This disk started as a blank disk, and had a FAT filesystem written to it from inside it; thus
+writing the detected geometry to the disk. And this caused the detected geometry to change to
+something nonsensical."""
+reproduce = """1. Unpack the attached [hd.bz2](/uploads/53f5bb00cdd563223bea1f7a0f86fe1c/hd.bz2) to hd.img
+2. Run qemu -hda hd.img
+3. Observe error"""
+additional = """The following command appears to fix the problem; however it is wrong:
+
+qemu -drive if=none,id=dr,file=hd.img -device ide-hd,drive=dr,cyls=1023,heads=16,secs=63
+
+The problem with this command is this command yields only 504MB instead of the 512MB the
+disk is actually formatted to be. CHS translation should be enabled on this disk but won't
+be with this command.
+
+This command was copied essentially blindly from "Removed features" because that's what comes
+up for a google search for "qemu specify geometry" and I don't understand the command well
+enough to correct it."""
