It all started with 'clearing disk space'.

Hey guys,
So i'm having this grey blank screen problem.
1) It started off while i was trying save some documents, didn't work so I went to Disk Utility, cleared the free space and then it was fine.
2) I then tried to surf the web on safari. Some sites couldn't load and some sites did and all of a sudden, my mac just hanged.
I tried to restart/shut down my mac through Finder and it just didn't restart/shutdown so I used the power button instead.
Lo and behold, it took so long to boot and when it did it came to a blank screen.
I did everything I could find on this support page.
1) Ran it in safe nothing happened
2) Ran it in recovery, nothing came out
3) Then it came to a grey screen when I tried rebooting it so i did the PRAM thing and that brought my mac back up.
So to check on it I did an 'EtreCheck' and here it is, seems to be... okay?

Problem With Low Disk Space - Message - Email and ...

Hi all,
I have a N97 and i noticed that when i have around 200 stored messages in my sent and my received in box then i get the e-mail disconnecting and saying to me that it's been disconnected due to low disk space.
So i tried changing the location of the folders for the e-mails and then i got a warning about the folders not being correct and had to restore them to the original settings.
I'm sure this is also related but some one tried to send me a small video via blue tooth and it told me that the memory was full but for the life of me i can't seem to change where a blue tooth message would go too.
Thanks in advance for any tips.
i know i may have 2 separate issues here but it's all the same low disk space or out of disk space etc etc
it would seem that it's a problem so how can i go about fixng it, it's poor...
The first offering is Nokia's new 'Messaging' client. If you really, really have been looking forward to this then by all means install it, but beware that it will, between application and messagebase, use up a lot of disk C: on its own. And you can't switch the messagebase to 'mass memory', because that gets locked out when you connect your N97 up to your PC or Mac, switching Nokia Messaging back to C:. As a long time Gmail user, I still find it easier to use either the 'old' S60 Messaging application (in IMAP4 mode) or just use the standalone Gmail (Java-based) application, which has the benefit of speed and of an utterly minimal footprint in daily use.
Also offered via 'Sw update' is Ovi Maps 3.1, which also insists on ensconcing itself on C:. If version 2.0 is working well for you then there really isn't a compelling reason to update, to be honest. Or at least not one that's compelling enough to warrant signing over at least 7MB of C: to it. If version 2 isn't working for you, you still shouldn't install v3.1, as offered, but go for the very latest v3.3, from the Nokia Beta Labs Maps page. It's faster and slicker and at least you'll be getting extra functionality for your lost Megabytes, including less troublesome GPS performance. See below for more on the GPS.
Next is Ovi Contacts, a beta-quality social integration system that's yet to take off in any meaningful way. Again, just avoided unless you really, really want to get involved. You don't need to lose the vital Megabytes.
Then there's the N-Gage games client, another C: biggie, seemingly swallowing up 6MB or so in a real world installation - if, like me, you're rather underwhelmed by N-Gage titles (in fact, underwhelmed by gaming on Symbian in general, but that's another rant for another day), then just say no and, again, give your internal disk a break.
The final optional 'Sw update' was Quickoffice 6, bringing compatibility with Office 2007 documents. This also takes up the best part of 10MB on C:, so unless you get a lot of Docx or Xlsx files by email then I'd strongly suggest holding fire on this update - you'll probably get it anyway in the v20 firmware in a few months time.

Solved!
Go to Solution.

Hi, don't know wether you've done this, but go into messaging/options/settings/other/memory in use/set as E:mass memory. If this causes a problem with email, simply delete mailbox and re-install it, it only takes a couple of minutes. One other thing , if you want to save any txt messages, sync with ovi first.Also to get C memory back delete all messages sent , recieved, reports etc before selecting Memory in use as E. Also go to web browser and clear privacy data regularly. One other thing to note is that usually when connected to computer via usb, messaging memory will revert to C, and you won't be able to see any messages , so reset to E again and they are all there. Best taskmanager from Ovi store is also a real help with memory on phone.
Hope this helps, and my appologies for the somewhat eratic layout nof the advice. Should have mentioned clearing messages from C before using E !
Good Luck

G'day. I am using iMovie 11 and need to clear disk space. How can I do that using an external drive, leaving me the option to go back and make changes or access old events or projects from that external drive?

G'day. I am using iMovie 11 and need to clear disk space. How can I do that using an external drive, leaving me the option to go back and make changes or access old events or projects from that external drive?

The slightly bigger question is whether you want to move all movie content to the external drive (essentially meaning that drive will always need to be attached when you're working with your videos), or whether you just want to archive older videos off to the external drive.
If you want to move all videos, then just move the 'Movies' folder in your home directory to the external drive, then create an alias of the external 'Movies' back in to your home directory. Now the 'Movies' icon in your home directory will point to the external drive and everything will just work (as long as the external drive is attached when you launch iMovie)
If you want to archive older movies then each Movie should have its own subdirectory within your Movies folder. These can easily be moved off to the external drive, and moved back should you ever need to work on those movies again.

RMAN9I HOW TO RESTORE ARCHIVE LOGS WITH LIMITED DISK SPACE

제품 : RMAN
작성날짜 : 2002-12-09
RMAN9I HOW TO RESTORE ARCHIVE LOGS WITH LIMITED DISK SPACE
==========================================================
PURPOSE
이 자료는 Oracle 9.2 이상의 RMAN에서 사용 가능한 MAXSIZE 기능에 대하여
설명할 것이다.
How to restore archive logs with limited disk space
Old Backup을 사용하여 RMAN으로 database를 recvoery할때, 모든 archived
redo logfile들을 Restore할 destination의 disk space가 모자란 경우를 종종 만난다.
이러한 경우 여러 개의 restore and recovery job으로 나누어 수행한다.
즉, 첫 번째 restore and recovery job이 끝나면 archived redo logfile들을 지우고
다음 적용될 것들을 restore한다. 그리고 다시 Recovery를 수행한다. 이러한 작업을
원하는 시점까지 recovery를 하기위해 반복적으로 수행한다.
Oracle 9iR2(9.2.0.x)부터 RMAN은 MAXSIZE option을 제공하는데 이것은 archive log
file이 restore될 disk의 space를 control할 수 있게 해 준다.
만약 disk space가 매우 제한적이라면, 즉 예를 들어 모든 archive log의 size 합보다
disk free space가 적다면 MAXSIZE option을 사용하는 것은 매우 유용하다.
이 OPTION이 기술되면 RMAN은 Media Manager에게 disk space 크기에 부합하는 만큼만
archive log들을 restore하도록 한다. 부가적인 restore operation들은 restore된
마지막 archive log가 적용될 때마다 발생한다.
MAXSIZE option은 이러한 작업들을 하나의 rman job으로 처리하게 해 주고
실수를 하지 않게 해 준다.
아래는 MAXSIZE를 설명하기 위한 예제이며 총 6 단계로 구성되어 있다.
STEP 1: Add data to the database to enforce log switches
STEP 2: Backup the database and archive logs and delete the logs
STEP 3: Add additional data to enforce new log switches
STEP 4: Remove the data file and simulate a database crash
STEP 5: Restore the data file from the backup
STEP 6: Recover the database using MAXSIZE
위 예제는 Unix와 Windows 모두에 적용될 수 있다.
STEP 6 는 다음과 같은 조건으로 두 번 수행될 것이다.
1) MAXSIZE가 archive log size보다 작은 경우:
이 경우 RMAN-6558 Error message를 만나게 된다.
그러므로 MAXSIZE를 archive log보다는 크게 설정해야한다.
2) MAXSIZE가 archive log size보다 큰 경우:
예를 들어 여러 개의 archive log를 포함할 수 있을 정도로 크게 설정하면
restore/recovery는 user에게 transparent하게 수행되어진다.
즉 archive log들은 restore된 후 applied되고 deleted되어 진다. 다시 새로운
archive log들이 restore되어지고 applied된 후 deleted 되어 진다. 이러한 작업은
recovery가 끝날 때까지 반복되어진다. 이러한 작업들이 진행되는 동안 RMAN은
아무런 Message도 발생시키지 않는다.
# Step 1: INSERT enough new data to generate log switches
create table rman_tst (col1 varchar2 (10));
begin
for i in 1..30000 loop
insert into rman_tst values(i,'test');
commit;
end loop;
end;
# Step 2: BACKUP the database and the archive logs automatically
# and then delete the input
run {
backup database format='/web01/usupport/krosenme/admin/backups/db_%d%s%t'
plus archivelog format='/web01/usupport/krosenme/admin/backups/arch_%d%s%t'
delete input;
# Step 3: INSERT enough new data to generate new log switches
begin
for i in 1..30000 loop
insert into rman_tst values(i,'test');
commit;
end loop;
end;
# Step 4: REMOVE users01.dbf file and crash the database
mv users01.dbf users01.org
shutdown abort
# Restore is now needed as the data file is deleted. The backup was
# taken before the new data was added to it, thus archive logs are
# needed to bring the database up to date
# Step 5: RESTORE the data file from the full backup
run {
restore datafile '/web01/usupport/krosenme/oradata/kro_920/users01.dbf';
# Step 6: RECOVER
run {
recover database delete archivelog maxsize 10 K;
# This will fail with RMAN-6558 as the archived log has a size of 16 KB,
# which is bigger than MAXSIZE limit of 10 KB. So the error is expected
# and MAXSIZE works as designed.
# Now rerunning STEP 6: but with MAXSIZE 50 K
run {
recover database delete archivelog maxsize 50 K;

Recovery Manager Reference, Release 2 (9.2)

cold backup means offline backup, you shut database normally and copy datafiles to another location.
i think operating system does not matter that much but it is RedHat Linux Enterprise Server.
backing up archivelogs whith rman script which is:
run {
allocate channel c1 type disk format '$BKUPLOC/arch_%d_%u_%s_%p.bkp';
change archivelog all validate;
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
backup archivelog time between 'SYSDATE - (30*60/(60*60*24))' and 'sysdate';
release channel c1;
so here is the details.
1. because everything is lost, we restored all files(datafiles, controlfiles, redologs etc) from offline backup meaning copied all files from another location to corresponding location.
2. want to apply archive logs which were created after cold backup till disk failure and we have these archive logs with backups which were taken by rman.
So
first of all, we want to register these archive log rman backups(because these backup information does not exist in restored controlfile)
and then restore them and then apply them.
we need rman commands to register these backups and restore them.

Kamil

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

NO power on my MacbookPro: it all started with Battery of my MacBook Pro saying it was not charging (even if the pro was plugged) and it then switched off and now wont turn back on. There is no light on the magsafe and no startup noises at all.

If you have Apple Care or your computer is still under warranty, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Need help with Low disk space issue and blue screen

Hi Everyone, just seen a message stating a low disk space on my Mac pro bought last November and tried plugging in an external hard drive to remove some pictures to free up some space but it seems that the computer did not have enough space left to start up and run the hard drive. I then tried to restart and ended up with a blue screen and have no knowledge now how to fix this problem. I phoned support but they say I have no technical support left but do have warranty and I would need to either try with the community here or take the unit to an apple store for an appointment. The store is an 1 and 1/2 from me and I really want o see if there is another fix that could allow me to start again then remove some files and then add external drive to remove more. I was blown away at the low amount of storage.....looked for the icloud option last night to upload there as i was told about this by a UK client of mine and now see it is not up and running. Any advice or help by the communtiy would be greatly appreciated as this is my business and travelling laptop. Cheers, Dean <")))><

Great to hear Dean, thanks!
Further notes: OSX needs about 15% or 10GB Free space minimum, but will run mucch faster/safer with 30-40% or 50GB of Free Space... Free Space is no longer ours to use.
Another tool to help clear up assorted things is Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

Encore 1.5 Transcoding could not start not enough disk space

Dear all,
I have a relative new raid 0 with four Hitachi (HDS721075KLA330) disks. At the moment I've got 2794.54 GB capacity (quite enough) and 1825.83 GB of free space. When finishing a Encore 1.5 project for making a DVD folder there is the error message: "Transcoding could not start there is not enough disk space available. 0 is available on E:\, 237.55 is required. Please free up disk space." Also messages during saving: "No disk space".
The weird thing is I've hadn't had this error before using the same raid disks, but since a few days I am stuck.
My OS is Windows CP Professional (SP2), 2 GB RAM, Radeon X1650 video card, Matrox RT.X100 video editing card. Thanks for your help.
Hans Hermans

If I remember correctly, this is a bug caused by the sheer size of your target array. In the olden days when 1.5 was the released version, Terabyte drives were uncommon, and the package could not actually see it as this large, and will throw this error.
The workaround was to partition the target array into smaller sizes (less than 1 Terabyte) and you should be able to return back to normal.

Migrating a 300GB Aperture library with limited disk space.

This morning I decided to migrate my 300GB Aperture Library to the new Photos app on my MacBook Air. I have 20GB of remaining space on my internal drive and thanks to Apple's use of hard links I was hoping this wouldn't be an issue when migrating.
After choosing to use iCloud Photo Library I was prompted that I would need to upgrade to the 500GB plan which I did. After completing the purchase I was then prompted that there wasn't enough space on my drive to download the current contents of my iCloud Library (13GB). Having 20GB available I thought this quite odd but proceeded to use optimised storage. It's worth noting that the entire contents of my iCloud Library already exist in my Aperture Library which I'm attempting to migrate. I was hoping the Photos app would be able to determine these duplicates before downloading everything!
The real kicker came when Photos app began processing the library. After reaching 3% I was informed that I would need approximately an additional 53GB of space in order to migrate this library! Freeing up that much space on my internal drive isn't a possibility without removing my Aperture Library so I'm going to have to complete the migration on an external drive.
Side note: It would be nice if Apple assed all space requirements before requiring me to pay and upgrade my iCloud space. It might be several weeks before users are in a position to actually utilise the space if such barriers occur at this point in the migration workflow.
I have now copied my Aperture Library to an external drive and I'm performing the migration on there.
I'm assuming that the additional 53GB of space the Photos app required is purely for the purposes of migration. It seems a hefty amount of disk space (roughly 18% of the library size) to be consumed otherwise. After migration is complete I'm hoping the Photos Library will only consume a small additional amount of space considering the master images and previews are hard linked. If this is the case then I should be able to copy the library back to my internal drive.
Couple of questions:
1) Is this 53GB of space required purely for migration?
2) Will I be able to copy both the Photos Library and the Aperture Library to my internal drive, preserving the hard link relationship between the two? If so, would this need to be achieved via the command line or should the Finder resolve this?
I'm worried that initiating a copy from the Finder, will in effect see the hard links for the original files, therefore requiring space for both full libraries. Ideally I would like the files to behave in the same way they would had I carried out the migration on my internal drive giving me the freedom to preserve (and therefore open) the Aperture Library in the future on my internal drive.
Thanks in advance.

Some, many, most IT Professionals would run sample benchmark tests to see for themselves what occurs.
Are you incapable or unwilling to run your own simple benchmark test to learn how Oracle's behavior might impact your database?

How to migrate from my old MacBook Pro to a new one with less disk space and an external hard drive?

I have just bought a new MacBook Pro and an external hard drive.
Yet I have problems migrating data from my old MacBook Pro (more internal disk space with around 500 GB data) to my new one (internal disk space less than 500 GB).
I have connected all 3 devices but it seems the Migration Assistant does not have an option for us to select to migrate to an external hard drive.
Any other way to do it?
Kindly help me. Thanks.

For your situation, Target disk mode may be the most efficient method:

HT201612 clearing disk space in mac drive in windows partition

I am using MacBook Air and having both the operating system installed (Windows and linux).
My windows partition "BOOTCAMP" is having 79 GB (30 GB is still free) and Macintosh HD is of 32 GB (only 19.6 MB is free).
I am not able to login to Linux operating system because of low disk space.
I am able to login to Windows OS. I want to clear some dispace in Macintosh HD.
I would request for some help in this regard.

It is not clear how many operating systems you have, two or three. If you have a Bootcamp partition for Windows you can not have three partitions because Bootcamp won't work with more than two partitions. If you want to remove the Bootcamp partition to free up hard drive space you must use Bootcamp Assistant to remove the Bootcamp partition and return your hard drive to a single OSx partition.
So try to better explain what you have and what you want to do.

File with appropriate disk space, but with nothing on it!

Hi!
I have this friend whom accordingly recorded some her stuff. Everything was fine then somebody did something with it (and can't explain what exactly) and now it's still as big as before (like 700 Mo of disk space) but when you open it, well there's nothing!
Do you know what probably happened? Or if there is a software which ccan help retrieve the lost data (if indeed this seems the case)?
Thanks a lot and sorry for the bad english, good night to you all!
Miranda.

BRAND NEW Macbook Pro with decreasing disk space

I recently bought a Macbook Pro with supposedly around 750 GB of disk space. However, when I checked it before I installed windows on it, I noticed that there was only about 430 GB available.
I downloaded less than 10 apps, and only brought over less than 50 GB worth of pictures, audio and movies from my Windows.
Can someone PLEASE explain to me how I managed to acquire almost 300 GB worth of this 'other'? An explanation besides 'things that don't fit into other categories' would be very helpful.
This is less than a week old and there's almost nothing new that I've created or worked on with this Macbook. My apps don't take up that much space, I don't have backups, Time Capsule is NOT on, and the most I've done with changing system preferences is to change my wallpaper and screensaver. So where is this all coming from? I honestly feel that I've been cheated of the 300 GB which was almost the disk space of my PC that ran Windows! And I never even used up that much since I bought my Windows!
At any rate, how do I get RID of it?

See if these Links offer any Insight to your issue...

Prime Infrastructure 1.4: Clear Disk Space

In order to reduce disk space usage on Prime Infrastructure I will reduce the System Data Retention period (for aggregate data) and "Background Data Collection Task" raw data retention (for non-aggregate data). If I now run 'ncs stop / ncs cleanup / ncs start, will this inmediately clear the disk space or does some other event clear the disk space?
Thanks.

ncs cleanup should be able to retrieve some disk space.
You can check the details of how it works from this document here.
