Strange problem with FREE

Whilst checking the output from a FREE command on my gaming PC (to see whether or not I got any negative values, per the recent thread) I got something that was even more of a surprise:

Code:

AFAIC the output from DIR is sensible (I have a 128GB SSD, which is almost wholly taken up by the primary partition from which this system boots, plus a 1TB HD which is filled by a single partition). Why would FREE report the same usage data for both partitions??

Not reproducible here
Well I wish it wasn't reproducible here either, but it is consistent and I cannot think of anything unusual about my setup at a disk partitioning level. Which API gets called for this?? I'll knock up a little test program and see if I get similar results directly.

Do you have an alias for FREE?
Nope, but it matters not:

GetDiskFreeSpaceEx().

This would be extremely noticeable if it was widespread, so I strongly suspect it's something specific to your system.

(Did you try it with 13.03.45? I made a couple of changes to work around redirector bugs.)

Well GetDiskFreeSpaceEx returns the correct values on my system, so I strongly suspect that it is something specific to Take Command ;)

I grabbed the sample code from this Microsoft support page and compiled it unchanged (as freedisk) and herewith the output:

Code:
C:\Users\Steve\AppData\Local\JPSoft>p:\d\develop\c_source\freedisk.exe c:

I tried but having (very briefly) sampled the v13 beta last August I find myself unable to run an unregistered version as my trial has expired.

And yet you're the only one with the problem, so I'm throwing it back on your system ... :p

Try downloading TCC/LE 13.03.45; it has the same code for FREE as the full TCC.

Touche :)

Okay. It returns the correct result for C: so you've fixed it (either with the latest change or some earlier change made to v13, since I've no idea whether or not it happened with previous builds). I guess now you're going to suggest that I upgrade to get the fix??

I've been racking my brains trying to think of anything on this system that might be 'getting in the way' and I wonder whether it is the Intel 'Rapid Storage Technology' software that was pre-installed. I'd uninstall it but I'm unsure as to how essential it is (eg. I think it handles TRIMming the SSD, but suspect that perhaps native Win7 does that too, but the information I can find is somewhat conflicting)

I made a change to v13.03.45 to work around a bug in some redirectors, which may or may not have affected your particular problem.

I might do a v12 update in a couple of weeks (to include a half-dozen fixes for various Windows & third-party bugs). If there isn't anything else in v13 of value to you, I wouldn't recommend updating just to get this fix. (But if you did decide to upgrade, we're running a 20% off special this week to celebrate the new web site; just enter "newsite" in the coupon code field.)

I was only joshing anyway (perhaps I should have added a smiley) but for me there doesn't seem to be anything compelling in v13 (as a keyboard jockey all of the /= stuff leaves me stone cold) with VIEW being the most likely real benefit (but I'm contemplating getting the full version because as a mainframe techie there are several features in there that would make it a very useful tool)

if you did decide to upgrade, we're running a 20% off special this week
Hmmm, interesting. How long until v14 is likely to be released?? I'd previously decided to wait and jump from v12 to v14 and if the new version is coming along inside a few months I'll probably wait.

Well, your 20% discount nearly snared my cash for the upgrade but then the web site wanted to add back 20% for VAT, so I ended up passing (I didn't think that VAT applied to goods purchased outside of the UK, but the law is so complicated and changes often enough that I might well be wrong).
