Shrunk my external 1Tbyte hdd in windows into 900gig partition, and I formatted the remaining space in OSX into Apple Extended volume, it didn't work (no errors at all, just somehow formatted into a wrong filesystem) formatted again and it seems to stick, but the other partition got unmounted, tried remounting and somehow my shrunk partition becomes unrecognizable, booted back into windows and it tells me the entire drive is unallocated even the partition osx formatted, great, downloaded an app and it rewrote my lost partition table and my 800gig of data is back! hurray!
All these trouble just because I wanted to shrink a volume, **** it. I wish I have everything recorded and see if it was me that did something wrong, perhaps I formatted the wrong partition? But it still shouldn't be unrecognizable and becomes unallocated in windows. Whatever, I'm happy the data is back, but I have no extra hdd or internal space to back up this 800gig of data incase something goes wrong, sigh.
