October 4, 200619 yr I'm sure it was asked before, but I cant seem to find it via search for some reason: Why can windows see the full size of the Linux format/partition on any given drive , i.e., of a 400GB drive, Linux formats and shows it as 390GB available, whereas Windows sees only 372GB? Is the remaining space still available/accessable? or is it an optical illusion? FYI, I'm familiar with the way drive geometry/HD manufacturers see total drive space available vs actual full size partitions; this is a win vs linux question.
October 5, 200619 yr I think he is talking about the total size after format of NTFS and ReiserFS. Basically both have different overhead as far as formating goes. Each filesystem is different so the byte values are rarely going to be the same if the drive is formated differently. One thing that may be confusing also is that the sizes reported on the main page of Unraid are kilobytes and windows property pages report bytes.
October 7, 200619 yr Author Actually, hypyke that is not at all what I was talking about, but that was a good guess . I'm talking about just the mounted UNRAID ReiserFS shares in windows, showing up 18gigs shy. Seen in windows in My Computer, in details mode of course, under the total size column. It's a consistent 18GB delta in storage between whats shown on the UnRaid web interface and windows; 372 vs 390 gigs of the WD 400GB drive(s). Should I try to overwrite the windows 372gb?
October 7, 200619 yr Let 'size' = the size of the disk shown on the Management Utility (this is in units of 1024-byte blocks)... When Windows asks for the share size in bytes, we return 'size' * 1024. Windows takes that result and divides by 1,073,741,824, drops the fraction and shows the result in units of "GB".
October 7, 200619 yr Author I'll buy that , math certainly works... Just for ***** and giggles, say in the future we can mount an NTFS drive as a partitioned Unraid share, would it report any different than RFS (mounted in Windows)? and hypyke, I owe you an apology, you had the jist of it in your second sentence.
October 7, 200619 yr I'll buy that , math certainly works... Just for ***** and giggles, say in the future we can mount an NTFS drive as a partitioned Unraid share, would it report any different than RFS (mounted in Windows)? It would report exactly the same. and hypyke, I owe you an apology, you had the jist of it in your second sentence. Any place windows does not display the full number of bytes, it uses the following units: MB = 2**20 = 1,048,576 GB = 2**30 = 1,073,741,824 And this has prolly been a never-ending source of questions from billions and billions of users who wonder why their hard drives are smaller than it says on the box. There has to be one head guy over there who refuses to change this particular quirk about Windows out of pure spite...
