I have the same issue, I even tried deleting the application and chaindata folder and installing it again. Same story, even with the geth --fast command it still takes several days to sync the whole chain.

Same problem. The wallet is basically unusable right now. I have tried to delete chaindata several times and also tried many different geth commands, but each time it will stop at a new block. The only time I was able to get in with an updated wallet balance was when i tried to run geth --light overnight, then launched the wallet. However after closing and restarting the wallet the sync was restarted from 0 again.

Had the same problem for weeks now. No one is working on it. Seems that Ethereum requires an SSD as a system disc. Large disadvatage to bitcoin. Will create a lot of unhappy first (and last) time users.

@NeunMalsechs Conspiracy theory but imo these people are trying to force others to store their eth on online wallets

same issue with me.. i have 2 machines ive been trying to load it up on. one is not an ssd and it downloaded 8-10hrs.. well up until 3,200,000 and change and then it freezes up... my other pc has an ssd but i dont want to dedicate my primary ssd on my primary pc to a wallet so i had the blockchain stored on a separate 10k drive and im on day 7 with 47,000 blocks left to go.... i do not understand this...

I have to run it in light mode. Full or fast is unusable even on SSD.
To run geth from the command line:
Go to the geth dir (default is C:\Users\YOUR_USER\AppData\Roaming\Ethereum Wallet\binaries\Geth\unpacked) create a shortcut for geth.exe. Right click on it. On the "target" field add:
--syncmode=light
Run the shortcut. Keep the command line window open.
Open the ethereum wallet as usual. It will sync in light mode. First time may take a little while. Next time is very very fast.

Everytime you want to open the wallet you have to run geth trough the shortcut first.

I dont know if there are any security issues with it or any additional problems. Perhaps someone else can comment on it.

I hope it helps.

@burdo3417 Thanks for the hints. With this I could at least see my current balance.

Nevertheless this is a best a workaround, feasible for a technician, nothing that can be asked from business user.

And I fear that this is a problem of Ethereums architectural design. Especially since the developer community doesn't even respond to those reports. Will not be easy to fix. Despite the good marketing the Ethereum Foundation is doing, it will come back to haunt them.

I guess I will have to take another look at Lisk if I want useable Smart Contracts.

Elsewhere I saw the workaround described that works for me on a normal HD:

  • install parity separately
  • run it as 'parity.exe --geth'
  • start up mist when synced
  • keep both running....

Hi, we have just launched Mist v0.9.1, with Light Client integration (beta).

What does that mean?

  • Sync times reduced by an order of magnitude while staying safe.
  • Much smaller storage required.

How to activate?

Mist app mostly freeze my PC, it always occupies 100% disk performance and also make it fragmented.
My HDD now is almost burnt up and going to be broken down.
