How do I tell if I partitioned my SD card right?

---

I prepared my 8gb SD card (that came with the Desire) to receive LeeDroid's well-loved Froyo ROM, using ROM Manager. I specified 512mb for the EXT and 0mb for the swap. Windows shows 6.92GB free. I understand it can't see the Linux part, but the Quick Info app and HTC sees 6.92gb. Shouldn't they see about 7.5gb? Where did the 512mb go? How can I even check if RM put a 512mb EXT3 partition on the card (oh... I don't do Linux!).

Should I go ahead with the A2SD LeeDroid install or worry some more?


(Btw... my username is for sale. But if anyone wants it to name a ROM they created... I give it for you gratuit ).

An 8GB SD card only really has 7.456GB of usable space

Quick System Info, the phone and Windows all see the FAT partition of the card, so when they report 6.92GB it's accurate

That 512mb missing shows that the ext3 partition was successfully made, it should be reported as 512MB free in the A2SD storage bit in quick system info

Thanks. In A2SD storage in QI it says "Information not available". But could that be because I have not yet installed the LeeDroid ROM, and am still on the original Android 2.1 the phone came with?

Most likely yes, a custom ROM that supports A2SD+ creates symlinks between the internal storage and the sdcard, as these obviously aren't there in the stock Eclair rom then there is no link to the ext3 partition and free space isn't being calculated.

After partitioned my SD card, Quick system info shows me that A2SD storage only have 113MB. I checked with Windows 7 disk manager and see that there is a 488MB linux partition. So where is the rest space? Could any one help me out?

You want something that can read sd-ext like root explorer and that will tell you. A2SD is weird and it depends on how the scripts and stuff are done and installed. Sometimes you can look in storage settings and it will tell you there, sometimes you use an app like Quick System Info, and sometimes it is just useless and won't tell you. If you have an SD card partitioned with a primary FAT32 partition first, then a primary ext3/4 partition second, it will work.
