comment Daisy chain 2 external monitors on laptop without DisplayPort
Missed that... Sorry, but it's still possible. I'm finding it hard to find, but there are HDMI to Displayport adapters that you should be able to use. I don't know if you can chain with it, but I would check with StarTech regarding that. For example, StarTech HDMI2DP HDMI or DVI to DisplayPort Active Converter, Sadly it's somewhat expensive ~$80 USD - newegg.com/Product/…-15-158-264--Product

Why are you installing Python via macports? Python v2.7.10 is included with El Cap, and I think Yosemite... Is there something in particular that you are getting from Mac Ports?

comment Is it possible to detect the previous byte position on a hard drive after it has been overwritten?
@supercat, We could debate this forever going back over minuta. Instead I recommend Checking out Security Now podcast #419, where Steve Gibson discusses this issue in regards to Wear Leveling (specifically over SSDs). The point made is if the drive is whole disk encrypted before the wear leveling occurs, then the remapped sectors are still encrypted, and thus when the encryption key is "wiped" / erased, etc, the sectors are unrecoverable. Security Now Podcast 284 (grc.com/sn/sn-284.txt) also covers a bit of this too.

@JamieHanrahan, you are correct. I should of said, that you wipe it by destroying the key. I did not elaborate as well as I should have.

The only real answer to this would be to full drive encrypt the hard drive before it was used (or right after the Base OS install), allowing it to be encrypted completely. And then when you want to wipe the system, repartition / overwrite the drive. If the entire drive is encrypted, then even any mapped out sectors would be encrypted, and when the drive was wiped, and the encryption key unavailable, then the raw drive data is useless due to the fact that it had been encrypted.

Whereas if the drive electronics marked the sector bad, and remapped in a replacement sector, Chkdsk /r or /f shouldn't be able to read the mapped out sector. So I would believe that non-trivial to attempt to recover data from a mapped out sector.

@supercat We may need to agree to disagree here. I <b>agree with your core argument</b>. Where we seem to disagree is that your stating that a bad sector maybe easily readable. My argument is that sector was flagged as bad, thus it will be hard to read. 1) Since it is flagged as bad, then you will need specialized software or hardware to read it. I am referring to the drive setting the block bad, and not the OS. If the OS flagged it, then it could very well be a slow sector (and not a bad sector).

@supercat True. In that case, only a TRUE low level format of the drive could possibly resolve that, and most IDE / SATA drives will ignore a low level format request, unless you use the manufacturers software. On the other hand, that sector was swapped out for a reason. Recovering data from it may take some service along the lines of Drivesavers (or a specialized software like spinrite).
