Bitstamp only has two reports for btc withdraw: pending and finished. Those with finished will have their btc back. However, due recent events they go trough scrutiny to avoid ripoff attempt. What is a smart move on their part, i wish mtgox were smarter reagarding this
Bitstamp is standing on the shoulders of giants, to misquote Newton. They know (now) they have to be careful to not fall into the same trap as another well known exchange.

so there is no difference how both exchange give status of the withdraw,however mtgox had thousands stuck transactions and continue to allow it for more then 20 days. You really can not compare bitstamp and mtgox how they handle things not to mention huge backlog in support what mtgox has vs bitstamp.
Again: Bitstamp got a solid warning ahead of their problems. I am a little surprised by the fact that they didn't disable withdrawals at once, but let it go on for hours and hours before doing something about it. The situation at MtGox was very different. In the beginning only a few withdrawals were affected, and most of the stuck transactions got successfully double spent and reissued after a while. And noone knew what was happening. Not even the core developers noticed what was going on, until phantomcircuit managed to get a tweaked raw transaction through and warned MtGox about it.
I got an answer from Bitstamp support after a little more than 24 hours, btw. They quoted the news release. That's it. Nothing specific about my BTC.
On bitstamp account history there is enough information to find out is your transaction in blockchain or not. So not really a difference in my opinion.
Where? I can only find a timestamp and an amount. I can't find any transactions based on that alone.
I think i was clear about other questions and dont know what context to add it. So i will consider it as you do not want to answer ( at this time).
You could e.g. specify if you asked about BTC or fiat withdrawals.
