Well when formatted the card should have ~7.2 of that 8 Gigs available. And yes it is frackin impossible that the OS and preinstalled apps are using over 5 gigabytes...a freshly loaded desktop windows 7 won't even use half of that (depending on options).
win 7 takes 16gb and doesnt have options to reduce install size without using a very difficult to use advanced application.
anyways that asside i did notice that there is not a emmc folder in the system directory like on the incredile. also the camera doesnt function without the card unlike the incredible which leads me to believe this internal memory is meant to be used differentely.
Using: Thunderbolt (rooted+OC'd) Incredible (rooted+OC'd) Galaxy Tab (rooted).
Retired: Droid X (rooted+OC'd) gave to GF, Droid 1 (rooted+OC'd 1.25GHz) gave it to my lil brother, G1 (rooted) was stolen from me.
Noticed this. Kind of new to Android but did some digging with astro and a folder called proc was HUGE, I looked inside and there were literally hundreds of folders all containing the same 30~ files.

Just throwing this out there, but could it be virtual memory? I know computers do this (my mac has ~6GB of it) so maybe smartphones do this too. It could also be used for memory protection/ the fast boot thing. I know on my mac 4GB are used on the hard drive which are an exact copy of the DDR memory so that if the computer shuts off suddenly it can be restored and so that the sleep mode can use even less power. Maybe the quick boot thing on the Thunderbolt works the same way? Just some ideas.
Hey guys this was answered in another thread. According to htc this is a software problem and will hopefully be fixed in an upcoming update.

My guess is that there is a duplicate copy of the OS on the internal memory for security/backup reasons. In the event the phone is rooted, after the phone is reset, the duplicate OS is then rebooted, thereby unrooting it and returning it to factory condition. This was done on the HTC MyTouch4G for T-Mobile, and might be a common feature of HTC Androids moving forward.
Almost 70% of Internal Memory is Missing. - HTC Thunderbolt (Verizon) - Android Forums - HTC Community --- if you take the time to read this, near the end, it looks like it is 4GB and not 8GB, or it was 8GB and then half of it was partitioned to not be used, and then we get half of that (2GB).
Either way, I paid for 8GB and I'm only getting 2.40GB. After I get everything set up I have 2.39GB free. This isn't what I paid for. I realize a lot of it is partitioned up but again, I paid for 8GB, not 2.39GB.
