Google Health, a portal from Google to keep track of your health records, sport activities and anything that could be related one way or another to your health, is going to be disconnected at the end of this year, after 3 years of service.
This is very symptomatic. Truth is that I never even looked at it. I wonder how others like Microsoft Health Vault (4 years old) are doing but my guess is that not very good and this link seems to think the same:
http://news.cnet.com/8301-10805_3-20080403-75/microsoft-offers-transfer-tool-to-google-health-users/
They try to point to issues with privacy or hospitals not adopting it... Others say that Google simply couldn't make money out of a service with so much privacy constraints. But to me, this is just one more proof of our behavior as humans about health. It is something that we don't care about till we lose it. Maybe we are even program to forget about it because we don't want to be obsessed either about the idea that we are not immortal. We want to enjoy life without worry about those things. Of course, I am talking in general, but taking care of our health is something that is seen as "we need to do", not as "we love to do". A warning to many of those "solutions" where people is pouring resources to develop...

Fixing SD card corrupted
Note: I didn't recover the file, so, this is just for my documentation... No solution in here :(
So, my key file on the SDHC card is corrupted. When I try to copy it I get an error saying: "the file or directory is corrupted and unreadable". It is an Excel file, so, when I try to open it, I get "the file may be read-only, or you may be trying...". Whatever.
I run chkdsk and get: dadada file "is cross-linked on allocation unit" da da da, "cross link resolved by copying". It asks me if to convert or not lost chains. I say Yes, it says it did, but I can't really find the 344064 bytes that he claims to have saved in a file. Not sure where he put it. I can't find it either in the root directory ?!? And still can't open the file...
So, the digging starts... Checking the drive in my computer I can see that it is a 3.75GB. I can also see that I bought it at MicroCenter. Then I found this link:
http://usbspeed.nirsoft.net/?g=4gb
Which says:
Isn't the web nice! Thank you guys! By the way, notice that 3.75 x 1,073,741,824 = 4026531840 bytes. I guess that's why they call it 4GB. C'mon!! Anyhow, back to the error.
You can read here http://technet.microsoft.com/en-us/library/cc975110.aspx a small explanation on what cross-link means. Not that it helps, but...
The next thing I want to try, before attempting any fixes is to save an image of the SD card somewhere. Not easy to find a freaking software that does that, but then I found the dd command in Linux. And as I have no Linux around, I found that there is a version of it for Windows: http://www.chrysocome.net/dd. AWESOME!
Open a DOS command window where the dd.exe is sitting and execute dd --list which will give us a list of all drives (here is what I got on mine):
C:\Program Files\dd>dd --list
rawwrite dd for windows version 0.6beta3.

3,850M
3850+0 records in
3850+0 records out
I do it with blocks of 1M (recommended), so, it takes about 5 minutes and done! Now that I got the image, I want to recover the file. Ideally would like to work on the image, not the original, but do not know how to do that. So, I'll trust I have the image and will mess with the SD card directly.
I tried all kind of stuff but didn't work... :(
Testdisk seemed powerful but I only saw that it can do an image. Didn't see that it can help me recovering my file...:
http://www.cgsecurity.org/wiki/TestDisk_Download
Got this one that is supposed to help you get the files you want out of the disc, but didn't seem to work?!?
http://www.powerdatarecovery.com/power-data-recovery.html
Recuva gets to the point of listing the file, but says that 85 clusters are written on top by some other program... Trying to recover it with it gives me a bunch of garbage.
http://www.piriform.com/recuva/download
Also tried this but didn't go very far. Seems limited to 1GB so, didn't get to see anything:
http://www.easeus.com/datarecoverywizard/free-data-recovery-software.htm
Got the Zero Assumption Disk Space Visualizer. Nice to check the disk:
http://www.z-a-recovery.com/download.htm
From the same link, we got too ZAR9. Looks very nice and powerful. Unfortunately, what he recovers is pretty messy with fragments from everywhere :(. Couldn't get the file.
A last trick was to look for temporary files of Excel in the HDD of the computer. Unfortunately, couldn't find any in my home or work one. So, I am doom. Looked for my backup, 4 months old, and live with that :(. SUCKS!!
PS.: For those curious, I used DD to restore the image back into the SD card, as it was before running CHKDSK /f and it worked nicely.

Tyres for the GTI V
Got 225/45R17
Original tire: Bridgestone Potenza RE050 BW 91W (I guess this is the speed rating W:168mph, one day I'll check them... he he he j/k)
Retails for $243, installed in VW dealership: $289. Discount tire lists: $485 for a pair. (By the way, price is directly proportional to number of tires, nothing hidden...).
UTQG ratings: temp: A, traction: A, treadwear:140
This tire does NOT have warranty and wears out like hell. First set gone after 15K miles, second after $20k. I drive the car a bit hard and Texas heat must not help, but c'mon!
Time to change, so, looking in Discount Tire at:
Total: $416.24 for two tires. 500 A A Z*, 45K miles warranty.
Total: $275.54 for two tires (this is the price of one Bridgestone!), 50k miles/5 years warranty, treadwear: 420, temp A, traction A, Z speed rating (149mph). By the way, VW dealer cost was $348 and needed a rebate...
All tyres got good reviews, so, I had to pick one and I went for the Continental. Just didn't want to risk to get the cheapest one, in case I notice it on the handling. So far, as I am not racing, I didn't feel any difference, even with aggressive street driving. Paid about $720 with all the insurances...
UPDATE: tires lasted easily 30k. I am changing them again for the same tire. They are now called

Continental ControlContact Sport AS (some marketing deal with Discount Tire), and retail for $149. Should be $376.22 without including the warranty rebate for the previous tires which didn't last 50kmiles...
