256Gb SSD HD only shows 238GB?
Is 238Mb free for use of a 256Mb SSD blank Hard Drive normal?
Perhaps you can help me with a concern: I purchased this Micron RealSSD C400 2.5HD 256GB SATA 6Gb/s SED off ebay as new, knowing it would not be in a sealed box. It is from (supposedly) a wholesale case OEM batch.
The seller said new, but I noted some blue lock-tight in two of the six screw holes, plus a faint mark along one edge. These two suspect issues (blue & mark) make it appear as if it had been instated once. Is this normal or should I be "more than usual" suspected?
When I installed windows 7, it showed 1 partition reserved for system 100mb with 70mb free, the other partition with 238MB. I reformatted the second partition (238Mb) but not the first one (with 100Mb). I did Google the SSD HD and saw that only 238Mb would be available. My concern is with a Trojan Horse or spy ware. I've scanned with Norton but concerned it only sees the primary, as far as I know this stuff is above my pay grade.

The capacity is normal. 256G is in decimal - multiply 256 * (10^9/2^30) and you get 238 binary gigs.
1 binary gig = 2 ^30 bytes; 1 decimal gig = 1,000,000,000 bytes.

So what about the 100Mb in partition one. Was this set from the factory?

That's the "SYSTEM RESERVE" Created by windows during installation...so Yes in a sort of roundabout way you could say it was set from the factory. It should NOT be moved, deleted, resized...in short, perform no disk management functions on the SYSTEM RESERVE partition.

Windows creates that System Reserve partition during a clean installation to a blank drive. If you are going to format and re-install, I find it simplest and cleanest to use the Windows installer to delete all partitions, and then select FORMAT and okay the warning from the Installer about "windows will create new partitions etc etc.
