DU says I have 18 EB (exabytes) in movies on my 120GB SSD (I don't actually have any, well aside from the ones the system installs). Anyone else seeing this? That's more room than the drive advertises... feeling lucky.

Weird... probably a bug as that is impossible. Of course, it could have been photoshopped but no, I'm not doubting you :)

No, no Ps. I hope it's nothing to worry about. I have little faith in my SSD these days (especially reading all the firmware problems, etc.)...

Lol! From the size of the bars it looks like GB.

To me, it looks like it should be 18 MB.
 
That crappy bar thing doesn't work for me either. My entire Time Machine drive is classified as "Other" while it should clearly be in "Backups". Also, it sometimes tells me that 500 GB of 500 GB is free, when actually the disk is almost full.
 
Yet another secret Apple prototype out there? Virtually infinite storage anyone?
Anyways, like someone said, the bars don't work too well for me either.
 
My 32GB jump drive shows the exact same 18.45 EB for movies in a small piece like that even when there are at least 6 GB of movies on it.
 
Looks like an overflow to me.

18.44674EB is the value that can be stored in an unsigned 64bit integer word, so it looks like it's using a 64bit word to store the size of the data and for whatever reason, the variable is overflowing and getting set to all 1s. I wonder whether, if you booted with the 32bit kernel, would it show the size as 4.29GB (the size that can be stored in a 32bit integer).

You should report it as a bug, it's probably just a display issue, but you never know.

Thanks guys. That's much more reassuring! As I said, starting to getting paranoid about my SSD... that's what FUD will do to you ;)

I'll file a report.
 
Wouldn't a 18EB SSD be awesome?

Price point 32 000 000 000 000$, lol

Not so long ago, when having a clearout in the office I came across an HP pricelist from 1991. At that time, HP server memory was roughly £250 for a 4MB SIMM. (I'd guess the $ prices would have been roughly the same - $250). So the 16GB RAM that I have in my current system would have been £1,000,000, I paid £60 for it.

Prices are always on the rise. I payed $40 for 4KB (4,096 bytes) of RAM in 1980 and that was a bargain price. My company paid about $10,000 for 32KB of core memory for a DEC minicomputer in 1974. The 8GB of RAM in my iMac would be about $2,000,000,000 (and take up much more space) with that core memory.

You got it! But it is more likely an "underflow." If the calculated value is negative, by even 1 byte, it would display as 18.4 EB.

Apple either needs to check for a negative value in the calculations and make it zero or needs to display signed values. At least the graph gets it right!
 
I bet if you created a small movie it would go to zero. It's just interesting that it can create a negative value (and that their display routine treats it as unsigned).
