Advice on Reliable SSD Chipset?

Monday, November 9th, 2009

I spent the weekend transferring my data and applications to a new Crucial 256 GB M225 SSD, and after about 10 hours of operation, the hard drive simply failed. It failed while “hot” even — the hard drive lite jammed on, my MP3 stopped playing, and the system froze up — like my worst nightmare come true. How is this possible? It’s supposed to be solid state. It’s supposed to have greater than 1,000,000 hours MTBF. Yet, it’s true. No matter what laptop I put it into, I now simply get this on boot:

2100: HDD0 (Hard disk drive) initialization error (1).

The drive isn’t 100% dead per se. There is a little switch on the drive that puts it into configuration mode, and it will identify itself as a Yatapdong Barefoot device (instead of a Crucial device) in this mode. So presumably, the embedded controller is still alive and kicking, but even in this mode I can’t seem to reflash the drive’s firmware or re-initialize it to a state where the normal mode is functional. When I switch it back out of configuration mode, the BIOS refuses to enumerate the drive, and without enumeration I can’t even run a diagnostic on the device. It’s definitely not an OS issue — BIOS-level diagnostics simply refuse to recognize the drive.

Searching around in the Crucial Forum, it seems these drives “have a high failure rate”. So much for a million-hour MTBF. I’m not sure exactly what’s causing it, because it is entirely solid state, and the SMT process used to build these drives are a very robust and well-proven technology. My guess is it’s got something to do with the firmware or the controller chip; they already have three firmware releases out for this drive, and disturbingly you can reflash these from inside the native OS — seems like a great candidate method for deeply embedding malware into a PC. Well, hopefully I can just return this drive for a full refund, since it failed so quickly.

At any rate, I’m wondering if anyone can give some advice on a good, reliable brand of SSD to use. The few hours I did spend with the SSD were quite positive; the performance boost is excellent, and a large number of my common work applications greatly benefited from the extremely fast access times. I’m still a bit spooked by the idea that these drives can fail so easily, but then again, fundamentally if I were in a jam I am equipped with the tools to recover the data — these devices use simple TSOP flash memory, so I suppose in the worst case I could dump the ROMs. Fortunately this one failed young, so the quickest solution is to just return for a refund and try something else.

Poking around a bit on-line, it seems that this Crucial drive uses the same Indilinx controller and firmware as the OCZ Vertex, the Patriot Torx, and the Corsair Extreme series (based on the “Yatapdong Barefoot” ID in configuration mode). On Amazon.com, I can see other users are experiencing exactly the same issue with a Corsair Extreme Indilinx series device. So I think it’s safe to say I’d like to steer clear of a solution based on the Indilinx chipset, at least until this issue is patched — ironically, the Indilinx website’s motto is “Beyond the Spin” (who are these guys, Fox News?), but it seems to me like their website’s got a lot more spin than substance. A link to a datasheet or firmware spec would be nicer than the marketing fluff.

Thanks in advance for the advice!

Site Down — Note Changes

Wednesday, September 2nd, 2009

Site has been down for the past few hours because my poor little shared server can’t handle the slashdot traffic that has recently been pointed at my article on H1N1. On the one hand, I don’t have ads on this blog; on the other hand, it means I can’t afford a server strong enough to handle the occasional slashdot DoS.

I have reconfigured the permalinks and caching behavior in an attempt to bring it back up. If you encounter broken links to this site or if you observe strange behavior, I’d appreciate a note here as to what you are seeing. My impression is that this caching plugin causes the pages to look a little bit nasty at first when you load them when the server is under load, and eventually they get a bit prettier with all the images and backgrounds when things lighten up, but I could be wrong.

Thanks for your patience!

Update: post backlog limited to 5 posts and images removed from the latest name that wares to try and keep server load down. Will restore normal reading settings once the slashdot attack is over.

Update #2 (9/3): I thought the traffic would be down by now but my ISP is still recommending I keep the blog in lock-down with “ugly” pages and no images otherwise they might have to pull the plug again. I’m not particularly fond of tinkering around with the mechanics of wordpress, php and mySQL so I’m just going to hunker down and weather the storm for another couple of days.

Update #3 (9/5): Looks like traffic is down, I’m gradually re-enabling features of the blog. Hopefully, now if you see the blog it should look “pretty” i.e., the header is loading properly and the CSS is being served. I will try turning on images on the front page tomorrow if things are still going well. Thanks for your continued patience.

Update #4 (9/8): I think everything is back to normal after the holiday. Hi-res images should be back now. If you do see anything amiss, please do report it. The backlog of posts shown on the front page is trimmed to 5 instead of the usual 10.

Blog Upgraded

Monday, April 6th, 2009

Well, I’ve upgraded to the latest WordPress, cleaned up some spam and gave the database a once-over. Hopefully the annoying spam comments are gone for everybody.

Looks like everything made it through the upgrade okay, but if you see something amiss (in particular with how comments are processed) please let me know. Sorry about the disruption, and thanks to everyone who called the problem to my attention. Since I don’t check my blog with an RSS reader I probably would never have seen those hidden links…

Blog Compromised

Sunday, April 5th, 2009

Sorry about the ads that some of you are seeing on RSS feeds. It looks like over this weekend a script leveraged a vulnerability in WordPress to promote a draft post (hence the broken video), attach a bunch of ads to it, and publish it. I’ve demoted the post with all the ads but I’m still getting emails from readers that use RSS saying that they see ads appended to their feeds, so perhaps the hack has modified some of the core scripts for syndicating RSS feeds. I probably have to wipe and re-install wordpress to remove this problem, and probably manually edit the database as well, which will take some time…which seeing as I’m already late on posting last month’s Name that Ware you can tell I’m not having a lot of time these days. Thanks for your patience…

In the meantime, if someone can confirm that their RSS reader is still seeing ads in-line with content after this post is up, I’d appreciate it.

RSS Issues?

Sunday, March 9th, 2008

I got a note today from a reader that my WordPress blog’s RSS feed outputs XML with invalid syntax. I’ve been unable to reproduce this bug; has anyone else encountered this?
