Is there a good safe way to shrink the primary windows partition on a gpt drive?

Samsung Magician and Windows Disk Management won't do it.
Disk management can shrink your partition? That is strange.

EaseUs partition master home edition should be able to do it for ya.

Over provisioning is not really needed tho.

Perhaps, but this makes a pretty strong case for it:

I figure it can't hurt the drive to over-provision. And I can always undo it later if I ever really need the space.

Anyway, I just tried to reproduce the error to get a screenshot to show you, weirdly enough Disk Management worked this time. Something else must have been trying to access the disk the last time I tried, or at least that's the only thing I can think of.

Now I ran the benchmark with my new motherboard, drive is amost full, 92% full, its about a year old:

WOW! What a HUGE drop in performance....what's up guys? It can't be the motherboard switch, my guess is either the drive is slowly going or the SSD performance REALLY drops off when the drive fills up... I'll be doing a complete reformat here soon and a fresh install of windows 8 in a few weeks. Hopefully that will give me back my performance...I hope.... headscratch.gif

After deleting BF3 and all its expansion packs on the SSD I went ahead and reran the benchmark. Speeds are right back up to my original speeds. I guess provisioning more space on the drive is a huge deal for a 64GB drive...Now I know... Sorry bf3, you go on the HDD now. I can't really spare 20GB for 1 game on the SSD... Especially if it makes that much of a difference.
I'm now considering a SSD for my 2ndary storage drive.... HDD is too big and too slow for my Mini-ITX case...
Oh and little info, that 2nd test was from when the drive was 94% full. When I deleted bf3 It went down to 54% full, benchmark was right back up to original benchmark results. I can get a SS of that 2nd benchmark if someone needs it but the numbers are pretty much the same.

Good read.

I'm still wondering if I somehow borked my drive using the windows disk optimization function or something. Gonna give it a few more days for some proper GC now that I shrank the partition, but I genuinely can't figure out why my drive is writing ~150mb/s slower than it should. Shrank my partition down to 192GB and have 131GB free, so I don't think it's a capacity thing.

BLAHHHHHH. I suppose if nothing else I can just Secure Erase and reinstall.

Aww, shoot, never seen this before. Or I'd have joined already. Go ahead and add me to the list! thumb.gif

I just ordered a 500GB 840 last night, and am actually trying to sell/trade my 256GB 830. I have a listing on the forums if anyone is interested, and hope y'all don't mind me posting a heads up here about this.

Woooo for Samsung SSD's! tongue.gif

This is interesting can you do it without loosing data on the drive ? Its not as simple as shrinking the partition ? correct ? You have to shrink partition then enable it in Samsung software ?

My drive was formatted GPT, which the Samsung software doesn't like, but yes, it's as simple as shrinking the partition. If your drive is MBR, I'm pretty sure you can do it directly from the Samsung Magician. Since I did it in Disk Management, I also went ahead and quick formatted the remaining space into a partition and then deleted it just to make sure windows sent trim commands, but in theory it should do it automatically. Now I just have to let it idle for a while and wait for garbage collection to process.
post #1319 of 5733
What does optimize this drive do under the Samsung software doesn't that do the Garbage collection. Can you do that manually.

I've actually been trying to figure out what it does myself. It clearly takes a lot longer to run than the Windows "Optimize" function which sends Trim commands, but it's unclear what it actually does differently. One thing I find annoying is if you run Optimize Drive in Magician, if ALWAYS runs a benchmark immediately after, which to me seems kind of counter productive.
