Problem reading available free space on HD

Second time this has happened this week. Computer begins to lag, so I run Disk Utility and repair prmissions. Then I verify the disc. See attached screenshot for the result. I've ran disk utility from startup and everything began to work normally until this morning. I attemped to verify disk and got the same result that the drive was corrupt. It seems the issue has something to do with determining the correct free space on the drive... any ideas? Thanks.

First, repairing permissions, althout hugely popular, is a waste of time unless you have a specific indication of a permission error involving system files, which you don't and probably never will.
Live verification of the startup volume in Disk Utility sometimes produces false errors. Boot from your recovery partition (command-R at startup), launch Disk Utility from the Recovery desktop, and run "Repair Disk" (not "Repair Permissions.") If you get the same error and it's repaired, repeat. Also select the icon of the internal drive above the volume icon and check the SMART status in the bottom of the window. If it's not "Verified," the drive has to be replaced immediately. If you get real directory errors more than once in quick succession, you have a hardware fault in the mass-storage subsystem, regardless of the SMART status.

4GB Micro SD - No Available Free Space, But Card is Empty..?

4GB Micro SD - No Available Free Space, But Card is Empty..? do l need to reformat sd card and if so how
Many thanks

Then there's likely a way to format the card on your GPS. I know that I format my phone and camera cards in my camera and phone - they mount on my Desktop as "NO NAME" and I just manually drag file where they need to be on my Mac. There should be some sort of command on your GPS to format the card - check your owners manual if you're not sure where to find the format option.
Good luck,

I have virtually no space left in my startup disk and it keeps declining in available free space?

Ok fellow Mac people - why would my 500GB start up hard drive suddenly go from 489BG of space free to about 2BG free, and it declines in free space until I reboot the computer. Even after rebooting though it shows I barely have 3GB of space free. It has declined all the way down to 19MB free on my computer at one point!
My time machine backup goes back until Oct 26th and I did not have the problem at that time. The startup disk on that date is at it's normal capacity. Since the 26th of October I have upgraded to OS 10.7 and installed a trial of GoToMeeting - no changes other than that and my normal use. I have emptied the trash and got rid of a bunch of excess files I didn't need anymore as well, but that hasn't helped really.
Any suggestions on what is happening? And, if I go back to the 10/26 startup disk image on the time machine will that affect any other partitions or drives on my computer? I don't want to lose any work that has been done and saved to other drives since then.
Thanks
Liz

I am not familiar at all with that software; however, since your problems appear to have started after you installed it, I would very seriously consider uninstalling it using their uninstaller (if there is one) and/or do a thorough search of the entire hard disk for files containing that name. I'd also consider getting Omnisweeper to check my disk:

If you find that you have all your hard drive space back, then there is obviously something going on with that software.

Restoring problem, Out of Free space

OK, here is my problem.
I am trying to restore from a backup and I get the following message:
iTunes could not restore the iPhone "iPhone" because the backup could not be saved on the computer.
Additionally my computer will say Low Disk Space:
You are running on very low disk space on C:......
The problem is when this first appeared I removed about 5GB worth of programs on my C drive and when I tried to restore the same problem again.
I think that maybe when you try to restore it starts to put the information on your computer before transferring to IPhone. If that is correct, how can I delete those restores that didn't go through? (I.e. I had over 5GB of space at the start of the restore process and now I have zero space.) I think part of the problem is I have tried to restore like 6 times thus, taking up more and more space.
Thanks in advance for the help, I am so frustrated right now. I tried looking up the answer myself online but had no luck.

AppleRunner1,
Right Click Start> Click Explore> Find your iTunes folder, this should contain a folder labeled previous iPhone Back-ups, erase what you need to. But be careful if you erase the wrong one you could lose alot of your most recent data i.e. contacts apps and music.
Hope this helps,

Problems with a free space on C: drive - Nokia N97

Greetings to everyoneMy phone tells me that his C: drive is full and ask me to delete some data from his. Thats nice, but when i accessing C: drive (of phone) via PC suite or file manager on the phone i can't see any huge files on it. But memory description tells me that there is 68 or something like that megabytes of messages on it. I has been setup email client with imap access to the server. Laster on i has found that he store all messages on C: drive and changed to Mass memory, but after i tell phone delete it in old place he didnt done it. The question - Why? and hw to manage it? I didnt found any solution, so i reseted phone totally (

You need to sort this out as low memory causes all sorts of other problems
the situation arises from two factors:
1. The phone comes overloaded with junk installed onto C
2. Because you won't yet know the phone's idiosyncrasies, you will do things to eat up C memory.
the (or at least my solution which has worked for at least three days - good going in n97 land) solution.
1. Fantasise that Nolia will send you meaningful help by email
2. Wake up
3. Back up your user data (contacts, images, sounds etc) onto a card or off the phone.
4. Hard reset if you're feeling brave and then Reformat E
5. Re-install firmware
6. Reformat E (just to be certain)
7. Practice safe installation by making sure everything stores or saves to E
8. You will need Y-browser from Dr.Jukka (who I imagine fleeing through the Finnish night pursued by .....), any way: http://tinyurl.com/yuw58e
9. Phone Info app to tell you how much memory
10. Keep checking that messaging hasn't gone back to c again
there are other less radical and probably more sensible routes, I chose this to make sure nothing popped up to respawn problems

How can I solve the problem with a free space

How can I fill empty space where I have pointed to in the screenshot. It irritates me

It still irritates me, help if it possible to change this parameters or something like this

HT4137 No Free Space available to restore back up

My iphone 5 's power button stopped working and the battery was shot. I went to the apple store and they replaced it no questions asked. They told me to come home and restore from back up. Well, 2 hours later I'm still not restored. I keep getting an error saying iphone can't be restored from back up because no available free space. Can someone assist me in freeing up space?

Restore as new and sync back the desired content.
Just curious, did you confirm it was replaced with the same capacity device?

How do I erase the free space on macbook pro retina?

I went to erase the free space on my MacBook Pro Retina in the Disk Utility but it says not available for this type of drive. Is there a way I can get around this?

You can't use Disk Utility to securely erase a Solid State Disk drive, because of the fact that SSD's have limited write capability, unlike hard drives, thus have to protect the sectors from as little writes as possible.
In fact TRIM (wear leveling) is enabled to write new data to the least used sectors on a SSD each time.
The NSA guidelines for secure data destruction on SSD's is to grind them into a fine powder.
If you don't require this level of data destruction, you can do this trick below, but not often or you'll premaurely wear out your SSD.
Finder > Duplicate a small file repeatly in a folder until slightly more than 50% of the remaining free space on the SSD is used up, (use Activity Monitor) then delete this folder.
Then duplicate a different small file repeatly in another folder in the same manner.
What this will do is, because of the small file, OS X will fill the smallest unused spots on the SSD, the duplicates will fill the remaining free space half way, then the second folder will (because of TRIM) fill the other remaining 50% of the free space.
You can't fill your boot drive or the machine can refuse to function or boot, but because of the wear leveling this should overwrite all your available free space on the SSD once.
If you have a laptop and TimeMachine, there is a hidden database on the boot drive which will store a copy of the deleted data.
Then there is "versions" and it's possible a copy of the deleted data is stored in that cache file still on the SSD.
I can advise how to delete the TimeMachine backup file on the boot drive, but not the "versions" database or what it contains.
How do I securely delete data from the machine?
If your really paranoid it's likely best to reformat the entire MacintoshHD partition from recovery and then with a new user, then do the Finder > Duplicate procedure to overwrite the deleted data off the SSD, this way the "versions" and TimeMachine databases are also overwritten.
Nothing is safe anymore.

Need more free space

My kids are playing Sims 2 and occasionally the game will not load because the Imac says that we need more available free space. Does anyone know how to remedy this?
Also, would increasing the amount of Virtual Memory resolve this? If so, how do I do that?
Thanks,

The reference is to disk space not memory. Apparently your hard drive is too full. You either need to delete some data to make more free space or put in a larger hard drive or get an external drive and move some files from the internal drive to the external drive to free up space.
Virtual memory is under the control of the OS and expands or contracts as needed. There's no need for the user to modify the amount of VM.

Free space of mdf and ldf does not match with database free space

In SSMS i saw file size related properties and found below details for one database.Here values does not match with other properties. Here size of the mdf, ldf and total size matches with other values under each window. But Available free space of mdf and ldf
if added then it does not equal to Available free space shown in shrink database window and free space shown in database properties. This is true for any database. Why is it so? Please can anyone explain the logic behind this?
Under database properties:
Size: 91.31 MB
Space available:13.40 MB
Under database file properites:
mdf size:17 MB
ldf size:75 MB
under shrink database:
currently allocated size:91.31 MB
Available free space:13.40 MB
under shrink file-for data file:
currently allocated size:16.38 MB
Available free space:12.63 MB
under shrink file-for log file:
currently allocated size:74.94 MB
Available free space:55.62 MB

Hi,
Database properties and database shrink show the total (log+data) values. Others show the individual sizes, log and data separately.
I hope it helps.

This does not answer my question. If you add allocated space of mdf and ldf it equals to database allocated size.But i am asking why this ldf and mdf free space together(when added 55.62+12.63 ) does not equal to database free space?

Blocks have much more free space specified by pctfree moved off freelist.

We have a table with pctfree=0 and pctused=90 and experienced high session against it. During the high session, we saw lots of "read by other session", cbc chain, and "buffer busy wait" caused by the same sql (INESRT). The row size of of an average 4K with long raw. After got the block info for the "read by other session" and "buffer busy wait", I dumped the block. The strange thing is that all the of blocks dumped are not in the freelist and the available free space is over 1K.
My idea is: When the session named waiting_a experienced "read by other session" to find the block to insert data, that block must be in the freelist, otherwise the waiting_a wouldn't try to read it in buffer and wouldn't be waiting for it to be ready. Very shortly other session reading_b which was reading the block put the data in buffer and did the insert operation, and the reading_b completed its work of insert. My dump should be after reading_b completed. So the dumped block should contain the data inserted by reading_b. After that the block was got off from freelist.
But why blocks with 0x520 (1312)and 0x104c (4172) freespace got off from freelist? As pctuse is 90, a block will be got off from freelist when free space is less than 10% of the block size, and these two blocks have much more freespace.

knowing Oracle specifically warns against using multiple blocksizes
Nope. Oracle does not warn against using multiple blocksizes, anywhere in the documentation.
The only warnings I've seen (By Daniel Morgan, and unverified) claims that Oracle was negligent and only tested the SQL optimizer with an 8k blocksize.
I'm not sure that this is true, since it would constitute misfeasance.
I know that Oracle does extensive tesing on their new features, and the docs offer the multiple blocksize feature without reservation.
Uisng multiple blocksizes is a well established, proven concept.
DBA's have been using them for decades with IMS, IDMS and DB2 before Oracle came along.
I first saw multiple blocksized used with great success in the 1980's, and they are still in use today on many large databases.
provide a measurable idea what 'lots' constitute, and how much I/O is reduced in the shops you saw?There is load of verifiable evidence out there:
http://www.google.com/search?&q=site%3Awww.tpc.org+db_16k_cache_size
This UNISYS Oracle benchmark used multiple blocksizes to achieve optimal performance
db_cache_size = 4000M
db_recycle_cache_size = 500M
db_8k_cache_size = 200M
db_16k_cache_size = 4056M
db_2k_cache_size = 35430M
http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP100883
The IBM Oracle Technical Brief titled "Oracle Architecture and Tuning on AIX" (November 2006) notes that careful evaluation is required before implementing multiple blocksizes:
While most customers only use the default database block size, it is possible to use up to 5 different database block sizes for different objects within the same database.
Having multiple database block sizes adds administrative complexity and (if poorly designed and implemented) can have adverse performance consequences. Therefore, using multiple block sizes should only be done after careful planning and performance evaluation.

Disparity in Free Space Reported

I don't know if I am the only one who is experiencing this, but there is a big disparity in the available free space on my hard drive being reported by the Get Info window and Disk Utility.
I took a screenshot and attached it to make what I am saying clearer, essentially, it appears that the used space and available free space is either incorrectly being reported or is swapped in either Disk Utility. I have already repaired both the permissions and the disk and rebooted multiple times. The only thing I can think of is that I did have a Boot Camp partition for a little while, but it was removed by the Boot Camp Assistant. I am going to report this to Apple, but I am curious if this is something other people have found.

The "Local Snapshots" that Time Machine makes on laptops aren't counted by the Finder or Get Info, because they'll be deleted if necessary in most circumstances. See #30 in Time Machine - Frequently Asked Questionsfor details.

Automatically hard disk is loosing its free space space

My macbook pro is automatically filling it`s free space....Now it`s showing "your start up disk is full"....
But i calculated the total files and folders, am using only nearly 200 gb...but my Harddisk have 320 gb capacity
I tried deleting some files of 8 gb....then it`s show 8 gb free space available ..again after sometime it shows "your startup disk is full" and available free space will below 1 gb.

Emptying trash is only recommended, if you are certain the data in the trash is no longer needed, or if uncertain, you have it backed up elsewhere. Many people drag files to the trash assuming it is safely stored elsewhere. One of the most common misconceptions is that items sent to the Dock or Sidebar are safely stored. This is not true, and if someone were to trash a file they dragged into the Dock or Sidebar, it would be gone for good unless backed up elsewhere as the full file and not just an Alias (Shortcut).

Large, sudden loss of a lot of free space

Last night I got a warning that my start-up memory was under 1 gig. I looked at my available free space on my Macbook and saw that it had gone from near 30 gigs to about 770 megs. I've looked everywhere I can think of and can't find any new folders or anything that has transfered to it to cause such a change. Any ideas?

I would start checking around my hdd trying to figure out what is taking up so much space. Start with your hdd folder, checking the size on each internal file, trickling down to find what really big on your hdd. if you get into a folder that says it contains a large amount of data, but you don't see anything big in there, it may be hidden stuff, i've had that before. in that case, try this out: http://guides.macrumors.com/Viewinghidden_files_on_aMac

TS3992 My iphone will not back up with iCloud. it keeps popping up a push notification telling me that i do not have enough storage available for the back up. but in my settings and storage it tells me i have 2.8 GB of 5 GB free space, help!?

My iphone 4s will not back up with iCloud. it tells me i dont have enough iCloud storage available, that i can manage my storage in my settings, when i click the settings it tells me i have 2.8 GB free space out of 5 GB. i dont know what to do about this problem. it hasnt been backed up in 3 weeks. and if i still have icloud space avaliable on my phone i do not need to purchase more. i have very few aps backed up on my icloud. i do not understand this help me please

Go to Settings>General>Usage and see how much space is available on your phone (listed at the very top). The pop-up might be telling you that you don't have enough space on your phone to perform the backup, not that you don't have enough space in your iCloud acount to store the backup.
