CHKDSK // I Am Confused
-
CHKDSK and Windows Explorer "Properties" agree very well on disk capacity up to Four TeraBytes. Thereafter, CHKDSK appears to get flustered.

Chances are your friend is right: you have been ripped off. It's very easy for a drive to report a larger capacity than it actually has, and by not having any wiring for the more significant address lines (or more accurately the block number high addresses) can successfully write and read back from all of that capacity. Except ... When you come to read back the earlier stuff you wrote you find it's corrupt - because it's been overwritten by the later stuff. It's happened to me with some cheap large microSD cards, to the point where I only buy SD, USB sticks, and SSDs in general from one company (Sandisk) because I've never had a problem with them. If you go to somewhere like Fleabay, Alibaba, or Wish and see cheap large capacity stuff it's almost certainly a scam. Sorry.

There isn't a drive out there that's less than $double-digits per TB. $10 for a 2TB drive? You done got ripped off. These are going for $40 to $70 a drive. Anything less is suspect. $36 for a 16TB drive? Yon done got ripped off. 16TB drives go for $250 minimum. Those prices should have raised alarm bells after a quick search on NewEgg or Microcenter.

*Capacity numbers are estimates with OS compression. Your results will vary based on file types stored.
File explorer reports on actual disk capacity when looking at the full disk. When looking at a folder you're given actual size as reported by the file system and the space consumed on the disk. Compressed and Sparse files can thus report far more size than there is actual disk space.

Dave KreskowiakI was going to post exactly that. Over here in Canada, I've typically been looking at $30/TB as a semi-decent deal, and have found some good deals where the price got closer to $26+change / TB. Anything significantly lower is a scam, or misprint. We are talking about spinning disks, right?

No These are (Reputedly) Flash Drives and SSD I gave up on trying to guess what the acronym "SSD" means, several months ago "Some Sortta Device" is probably closest to reality. If it's okay to do so, I'll post links to them. All Three were eBay Red flag which I didn't observe: Delivery Times were far beyond typical eBay norms.

Thanks for the links. Seems that each one of those will take at least a day to provide useful results. These thieves have concocted a very shrewd scam indeed. And, from what I can infer, they are going to get away with it, and continue doing this, for the foreseeable future. But thanks anyway.

Their Facebook page only says "I am a 486DX-33MHz-64MB processing avant-garde chiptune, synthesized heavy metal & classical music." Can't really find anything else about it. I think it's mostly synths though since it seems to be one person.
