Yeah I think you're right. Still, it's strange that seedoubleu is reporting to have more than 14GB of 'bad sectors', what would be hidden there?
I still think this has something to do with the device's memory controller, because the 3+ GB really isn't accessible.
Hmm nice work HTC Not very neat
So I guess we might get in to problems when using a large amount of the supposedly available capacity
Just to clarify to everyone:
The bad sectors seen by chkdsk aren't broken sectors. But chkdsk is right in windows terms, it are sectors marked with the wrong property or a property unknown by windows. Knowing windows can perfectly handle FAT32 I will take a wild guess and say it is a wrong property.
To explain more:
If you delete a file, it is not thrown away, the sectors were it is on get the property "overwritable" so the OS shows them as "free space". Sectors assigned with a wrong property or not writable due to hardware error get the property "bad sector". Therefor it is theoreticaly possible to recover "bad sectors" if windows notices that those sectors are still readable AND writable. This is triggered by chkdsk /f /r
Like windows, your phone does NOT recognize bad sectors as writeable and ignores them as usable space, therefor you WILL loose that space on your phone.
Does that mean if we use pc to delete the files on phone'SD will cause those deleted space is locked and can not use any more? For instance you delete 1G on sd from PC but SD free space not change at all.

If you are lucky, the free space is go down just the same size of the file you copied to it.
I noticed yesterday that after updating Dark Meadow and my phone going funny and seemingly downloading twice I had lost 1GB of space and dropped to my last 200mb. I hooked up to my pc and checked the size of all the files and folders and it turned out I had lost 3GB of space!
I did the transfer data and format and have also restarted the phone twice and now I have my 3GB back but the phone is taking ages to do anything?
Looking at SystemPanel all four cores are working, my memory usage looks about the same as previously and the loaded applications and processes looks fine so what could be causing this severe slowdown?
I formatted to Fat32 and 16kb clusters as recommended.
