Yes, the wallet.dat file is from the bitcoin client. I did a rescan at the terminal and it said command not found.
First, close bitcoin-qt and stop bitcoind if it's running. If there is a wallet.dat in ~/.bitcoin, back it up and then replace it with the one from your USB drive. The restart bitcoin-qt (or bitcoind) with the --rescan flag, and give it a few hours (depending on your system) to rescan the blockchain for transactions in that wallet. Example: "bitcoin-qt --rescan". If that returns something along the lines of "bitcoin-qt: command not found", make sure you're in the same directory you compiled bitcoin in and run "./bitcoin-qt --rescan", or make sure it is installed properly and try again without the "./".
That didn't work either. More suggestions please, I need to resolve this. Thank you all thus far for your help.
Try running these commands, in order, from the directory on your USB drive containing the wallet:
1. killall bitcoind; killall bitcoin-qt
2. mv ~/.bitcoin/wallet.dat ~/.bitcoin/wallet.dat.old
3. mv wallet.dat ~/.bitcoin/wallet.dat
4. bitcoin-qt -rescan &
The first one closes any copies of bitcoind and bitcoin-qt, the second one make a backup of your old wallet (make sure there isn't another backup with the same name there first!), the third one copies in the new wallet, and the fourth one starts bitcoin-qt with the -rescan flag.
Let me know if any of the commands return errors, so I can help troubleshoot further.
Hope this helps!
I only have the wallet.dat file on my usb, that's all!!
Do you have bitcoin-qt installed on the system you're trying to copy it to? If so, those commands should work; if not, you'll need to install it first.
