Quick question for those more informed than me.  I had 38 BTC in a wallet backed up on November 7th.  Today, I loaded that wallet up in Bitcoin QT and sent 36 BTC.  I then deleted the wallet and put my normal wallet back in place, assuming my November 7th backup was all I needed.  However, I then put the November 7th wallet back into Bitcoin QT and the balance is zero instead of the expected 2 BTC.  The 36 BTC transaction from today also does not show up in the transaction history.

To see if rebuilding the block chain in my client helps, I copied the November 7th wallet to a fresh install of Bitcoin QT on another computer, but it will be hours before the block chain is done downloading.  What would you say I should expect to find after it's done rebuilding?

The reason I ask is because I remember reading once that when you send part of your BTC balance, the whole balance is sent and then part of it is sent back to you.  Would using the November 7th wallet make it so I don't have access to coins that the more up-to-date wallet I deleted contained?

Thanks in advance!



Edit: Well, the block chain finished rebuilding and my 2 BTC are back.  Woot!

Hello. Thanks for looking.

I have 131,000 American Express reward points.

I will buy anything for you that can be found in the following categories:

I'm asking 2 1.8 BTC per 1,000 reward points.  Other denominations of points are also fine.

eGift Cards are delivered via E-Mail in PDF format.  I believe I can specify your E-Mail address for delivery.  If not, I'll forward it on to you.  The two times I've ordered eGift Cards, it took less than 5 hours.

I believe that I can specify your mailing address for regular gift cards.  If not, I will mail the cards to your address after I receive it/them.  I will also E-Mail you a printout of the receipt from Amex.

Here's my eBay profile, in case it helps inspire trust.  If necessary, I can change the profile name to prove it's mine.

Although you can use Amex reward points for more than what is in the following list, I have filtered the list down to include only items that are a good value.
That is:
1,000 points  = $10
2,500 points  = $25
10,000 points = $100
etc...

Hello. Thanks for looking.

I have two $50 Old Navy eGift cards for sale at 10 9 BTC each.  I received them in PDF form, so I can simply E-Mail them to the buyer.  They can be used online or they can be printed and used at a brick & mortar store like a regular gift card.

This is the first time I've ever sold something for BTC.  Are PMs the best method of exchanging info?

Here's my eBay profile, in case it helps inspire trust.  If necessary, I can change the profile name to prove it's mine.

Thank you in advance for stopping to look at my post.

I mine using Bitminter's Java client, and up until a few days ago, I used an AMD 5970, which was giving me about 745 MH/s at 825MHz.

Then I swapped it out for an XFX 5970 Black Edition.  The only reason I swapped is because the XFX has an Accelero Xtreme 5970 cooler installed, which is substantially quieter.

When running the XFX at 825MHz I only get about 670 MH/s.  So at the same clock speed as the AMD card, the XFX does about 75 MH/s less.

I'm running Win7 Pro x64 and using Catalyst 11.10 drivers.

Has anybody here seen this sort of hashing speed difference between two video cards of the same model clocked at the same speed?

Thanks,
