The Acer Aspire One A110 hard drive massacree, revisited

 This whole blog post looks far too familiar: I previously replaced the crappy 16gb SSD in my Acer Aspire One A110 with a Samsung HS030GA hard drive. I made the non-mistake of fitting a used drive (it wasn't a mistake because the only seller on eBay that was doing rapid shipping only had used drives, and the monitor on my desktop was awaiting replacement; it was either that or a week without any computer, so there), and quite predictably, that died a slow and painful click-of-deathy death. Oh well!

I replaced it with a Toshiba MK3008GAL, which is apparently compatible with 5th generation iPods and Zunes as well, and it works perfectly with Ubuntu 10.04. Once again, if you're doing this yourself, you'll want to go watch tnkgrl's dismantling video, especially if you're replacing an SSD. Also, as I noted in the previous entry, the standard cable that comes with SSD-equipped A110s is too thick for these drives, so you'll need a cable which is 0.35mm thick on one end (typically with a blue connector) and 0.22mm thick on the other. The thick end goes into the motherboard, and the thin end goes into the drive.

I did encounter one bit of weirdness, which was that I got an error message while booting from the Ubuntu 10.04 USB stick which went something like this:

(initramfs) mount: mounting /dev/sda on [something I forgot] failed: Invalid argument

Weird, because /dev/sda was the new drive I installed, and "invalid argument" is (as far as I know) what you'd get if the drive had a screwy partition table or something else gone really, really wrong; apparently whatever data was on that looked enough like a filesystem that it would try and mount it, but not quite enough like a filesystem that it actually could. So I pulled two numbers out of my arse (hey, 8192 is such a cool number that I'll use it twice) and did this at the (initramfs) prompt:

dd if=/dev/zero of=/dev/sda count=8192 bs=8192

(Note people coming here from Google: Don't do this if you're not totally, more-certain-than-you-are-of-your-own-existence sure that 1) /dev/sda is actually the hard drive you've just installed AND 2) that you're 100% okay with irrecoverably losing all the data on that drive. Alternatively, if you're not worried about nuking whatever random drive is /dev/sda, that's OK too. This command nukes the first few dozen megabytes of the drive, including the critical partition table, thus making all the data on it unreadable.)

After that and a reboot, Ubuntu booted off the USB stick, installed, and worked flawlessly. The craptop sails again, hooray! :D

Acer Aspire One A110 with Samsung HS030GA hard drive

UPDATE: This drive died and I switched it for a Toshiba MK3008GAL, which also works great. See my more recent entry, The Acer Aspire One A110 hard drive massacree, revisited.

So the 16gb SSD in my Acer Aspire One A110 craptop finally went to the glue factory this week, and I replaced it with a Samsung HS030GA hard drive, apparently compatible with the drives from 5th generation iPods. I don't have much to add to tnkgrl's dismantling video (if you're doing this yourself, go watch it, it's long but she does an excellent job), other than one major gotcha: The ZIF connector cable used in the A110 will not fit into the Samsung drive; it's too big. You'll need a odd-ended 20.5mm cable (which I've seen called "Type A"). On one end of the connector you need a 0.35mm-thick (typically blue) connector which plugs into the motherboard; on the other, you'll want a 0.22mm (white) connector to plug into the drive. The cable I used was 100mm long, which seemed about right (a little longer than the standard one). Also don't forget that you'll need a good pair of side-cutters to cut away some protrusions on the inside of the AAO's casing; this is all explained in the video. 

Otherwise, tnkgrl used thick double-sided sticky tape; I found that 4 or 5 Sellotape double-sided sticky fixers on both the top and underside of the hard drive were of about the right thickness and did a great job. To simplify dismantling it later on (if I have to replace the drive again), I didn't remove the paper covering the adhesive on the motherboard side of the hard drive; the hard drive is already held firmly in place by the pads on the underside, and this way the fixers work as electrical insulators (presumably) and to damp vibration a little.

Have fun!

Three hundred and eighty eight thousand shutter actuations!!

Nikon D2H, Nikon 18-70mm DX at f/8, 9 seconds at ISO 200.

So my Nikon D2H passed 388,000 shutter actuations today. Here's shot #388,003.

I don't think I have anything to add to that. :)
