Advice on partitioning & B//U routine

What size partition do you give Time Machine?
I've read where TM will use all the space it can eat. If I have a 320gb drive internal - do I make only a 320 partition out of a 1tb external - or does it need more?
Alternatively, would I just be better off scheduling/using Super Duper or Carbon Copy Cloner? I need a bootable backup or two at the least.
Do any of them take advantage of Firewire 800 to speed the process? Any other comments welcome - thanks!

Sorry I missed such a fundamental thing - so for me a whole 1tb would be needed for Time Machine with my 320 internal - as I do large files (photography not video),
Not necessarily, especially if the internal isn't (and won't be) near full. If you do a lot of editing of those photos, and discard the intermediate steps fairly soon, TM won't need a huge amount of extra space. That's because it, too, does "intelligent" discards. If an item was on your system for less than a day before being deleted, it's backup may be deleted after 24 hours. If an item was on your system for more than a day, but less than a week before being deleted, it's backup may be deleted after 30 days.
An alternative is to do the editing on a disk, partition, or folder that's excluded from TM (via TM Preferences > Options), then move the finished product somewhere that's included in TM. That will save both the disk space and CPU usage, but of course then you can't recover the intermediate steps.
What I'd suggest is, put your TM partition first on the disk (at the top of the diagram that Disk Utility will show), and make it fairly large. Then put your CCC or SD partition next.
Then use TM for a while. It's first backup will be a full copy of your entire system; each hourly backup may be fairly sizeable, depending on how much you've added or changed. But after a day, when it starts "thinning" all but the first backup of each day, the net growth won't be as fast. After a month, when it starts "thinning" all but the first backup of each week, it will slow even more. Then of course, it will grow by the equivalent of one backup per week until the disk is full.
If you see that it's going to keep more backups than you want or need, you can then reduce the size of the partition, and use the space for something else.
Or, if it looks like the partition is too small, you can delete the next partition (the one below it), and expand into that space.
The reason to put your TM partition first is partly to use the faster portion of the disk, but mostly because you can't expand a partition upwards, only downwards.

Advice on partitioning: PPC + Intel

I'm about to give away my PowerBook G4 and get a new MacBook Pro. In addition, I just purchased a new large external drive which I would like to partition so partitions can be used to be bootable for both my MacMini (PPC) and my new MBP.
Can I set up a GUID partition (for Intel Mac) and an Apple partition (for PPC Mac) or must I make a choice for the entire external drive?
Thank you.

You can do both.
When you set up the partitions, as you write, the one for the Intel processor must be GUID, at least to make it bootable. According to the Disk Warrior site, for a bootable partition for the PowerPC, "the drive must be partitioned as "Apple Partition Map" (also known as APM)."
When the computer sees a partition, basically all it sees is another hard disk.

Partitioning Advice on PRIMARY FILE GROUP

Hi,
I wonder if you can help. I would like some advice on partitioning within the PRIMARY file group. Basically I have a lot of experience on partitioning and in the past I have followed best practice is documents such as
Partitioned Table and Index Strategies Using SQL Server 2008 and the
Analysis Services Performance Guide so in summary when partitioning in the past I have followed best practice, e.g. have one file group per partition and have your partition key as a component within the primary key of the table you are
partitioning.
However following best practice in this way can require a lot of maintainence, and the system I am performance tuning at the moment has a limited life span.
So in this context I wonder if there are any advantages of basing partitioning on a PRIMARY file group?
Kind Regards,
Kieran.

Hi Erland,
Many thanks for your advice which has helped me set a wider context.
I'm sorry, I think this question is drifting onto Analysis Services even though I started out asking a question related to Partitioning Advice on PRIMARY FILE GROUP.
Your answer increases my empathy with people who are skeptical about the performance advantages of partitioning very large tables even when these very large tables are the data source of a cube.
Is it possible for a question in these exceptional circumstances to be associated with 2 forums, i.e Transact SQL and Analysis Services? - since the scope of this question covers both areas.
I have had a lot of success in dramatically speeding up the processing of a cube with multi-billion record fact tables in the underlying data warehouse for previous clients. Where this cube had the partition key in the WHERE clause
of the Cube partition which was the same as the partition index in the underlying fact table. And where each fact table had a different physical file group for each partition. The cube, data warehouse, transaction logs, and tempdbs were on separate spindles.
However the partitions within the cube and the partitions within the data warehouse were not on separate spindles for each of the partitions.
A proven advantage of implementing the above design strategy is that it increases parallelism. Please see page 86 of the best practice document on
Analysis Services 2008 R2 Performance Guide.
So getting back to my question in the above context: If you slice on a particular partition with a particular partition key value, e.g. PeriodYYYYMM = 201408 on a relational database table, will it make a difference to performance if this table is partitioned
by the PRIMARY file group, or should the partitions have a separate FILE GROUP for each partition?
Kind Regards,
Kieran.

To partition or not in a new PB?

Hi,
I'm helping a friend set up their new 15" 1.67ghz pb and i was looking for some advice on partitioning the HD. I've never really done anything on a laptop, my main experience is with G4 towers and CRT imacs.
With my tower machines I usually have either a couple of HD's or if I have one larger drive, I partition it into at least two sections: one for system/apps and one for files.
My friends computer will have the stock 5400rpm 80gb drive, and will be used for a combination of word, email, internet, music, and adboe CS stuff (mostly indesign and illustrator).
So, I'm wondering if there are any pros or cons to partitioning drives in PB's or in tiger in general, because honestly, my habit of partitioning drives was learned in 9.0.4, mostly as a way to easily defrag the parts of drives that had a lot of audio recording files coming on and off all the time. having the system/application files on the part of the drive that didn't have so much data coming on and off all the time was always a big boost to disk performance for me.
these days I don't know, maybe it's less relevant in tiger? Or maybe not as neccesary when not in an audio recording environment with huge chunks of data coming on and off all the time? And I don't really have any experience using itunes/ipods. I am inclined to make a system partition, a files partition for word and design stuff, and then a partition that is just for itunes files...but maybe that's overkill. Any advice, experiences would be appreciated.
thanks.

When it comes to partitioning the choice to do so really comes down to how you use your computer and your personal preference. Even though there are less reasons to do so with Mac OS X there are still big benefits, and big drawbacks, of doing so. While there are more pros and cons than what I'm pointing out, not to mention millions of ways you can use those partitions, for me these are the main ones.
The cons
1) Fragmenting of disk space. This is probably be biggest drawback to paritioning your drive. The higher the number of partitions the worse this becomes.
2) Poor system performance. If you cramp your system partition and don't leave it enough space for its cache files etc you will find that system performance reduces and can potentially cause kernel panics. All it takes is a few unweildy applications, along with their own cache files etc, to give you problems in this area.
3) Higher maintenance. Having been a big fan of partitioning myself I always find instances where my paritioning is not optimal causing me to have to shuffle things around. This is just a huge waste of time.
4) Non-standard installation. For instance, if you wanted a second parition to be your home directory then your installation becomes somewhat non-standard and requires a lot more effort to setup.
The pros
1) Separation of system and data. You can choose to keep your data very separate from you system and applications. This scheme can make for simpler backup if you are only interested in backing up you data. Some people really like this and I used to do this with Mac OS 9 and earlier though now I find it too much trouble. If you're one of those people though
2) Separation of temporary data. Having had two partitions up until only very recently I found it very useful to have the second partition for temporary data along with data I'm not interested in backing up.
3) Second system startup. Two or more partitions does allow for a scond, or more, startup so if you want to mess around with a new piece of software or need an older version of Mac OS X, or Mac OS 9 for that matter, then this does make it very easy.
4) Cloning. If you split your drive into two similar sizes you can clone one parition to the other. Frequent travellers may find this incredibly useful as you would be self contained in an emergency. Being able to restore your system, excluding a drive failure of course, without any external devices is pretty neat.
EDIT: PS I've chosen to no longer parition because I find it simpler to just use an external hard drive.

How to compile Oracle Linux source?

I accidentally downloaded source DVD "Oracle Linux Release 5 Update 2 source - DVD" instead of installable ISO image. Is there anyway I can compile it to make bootable ISO image?
I tried to search this forum as well as other places but couldn't find any information hence thought of opening a thread before I proceed to download correct file which will again take 10+ hrs with my Internet speed :(
Any help is highly appreciated. Also I need to know which packages are required to be installed for compiling the source if at all that is possible. I am using Ubuntu 11.10 Desktop.
Thanks in advance for any help and hope to get a reply soon :) I need to urgently install Oracle 11gR2 on it.
Edited by: user6582219 on Apr 12, 2012 1:10 AM
While browsing the forum for any possible solution I came to a thread that discuss installation of a package oracle-rdbms-server-11gR2-preinstall. When searched through search engine I came to know about recent certification Oracle 11gR2 on Oracle Linux 6, here is the link https://blogs.oracle.com/linux/entry/announcing_oracle_database_11g_r2
https://blogs.oracle.com/linux/entry/announcing_oracle_database_11g_r2
Thing is I already have Oracle Linux 6 Update 2 (the latest) installed on my machine in dual boot mode so I dropped the idea of installing version 5.2. As per the documentation 11gR2 was not certified earlier on Linux 6.2 so I thought of installing 5.2 but it is not necessary now.
I would still appreciate if someone could answer my question just for knowing the procedure compiling source. May be it can help someone else trying to achieve this.
I have another couple of important questions and need guidance from the experts over here. I am not sure if it is appropriate to open a new thread but for now I am posting them here.
Before proceeding here are my environment details:
Machine: x86 32 bit with 2 GB RAM/250 GB HD.
OS: Kubuntu 11.10 Desktop and Oracle Linux 6 Update 2 in dual boot mode.
Here are my partition details for your reference but as I am planning to do the installation from the scratch following new ideal scheme you can jump to last paragraph following the line "*********************************" for my questions.
Unfortunately my partition plan went wrong and here is what I have now:
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x3d5ba9e1
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 1002047 500000 83 Linux
/dev/sda2 151525080 361253654 104864287+ 7 HPFS/NTFS/exFAT
/dev/sda4 1003518 151001087 74998785 5 Extended
/dev/sda5 1003520 7002111 2999296 82 Linux swap / Solaris
/dev/sda6 7004160 11001855 1998848 83 Linux
/dev/sda7 11003904 51001343 19998720 83 Linux
/dev/sda8 51003392 110041087 29518848 83 Linux
Partition table entries are not in disk order
/dev/sda1 here is /tmp, /dev/sda2 is my data partition, I have separate /home / (root) partition for Kubuntu and remianing around 20 GB in extended partition is used for Oracle Linux 6.2 with default Oracle suggested LVM partition. I also have separate /boot for Kubuntu and I chose not to install grub while installing Oracle Linux. I later modified grub.cfg to add entries for Oracle Linux and now I can boot both OSs successfully.
My issue now is I cannot extend 20 GB space (in extended partition) that I have given to Oracle though I have around 40 GB space available. This is because I alreay have 4 primary partitions (one for /boot others for "data" and one extended partition). So I have to make primary partition out of free space and install Oracle in a single partition without following recommended partition layout scheme.
Now I want to do the installation of both the OS from the scratch and really need an advice on partition layout scheme. Here is summary of what I wan to achieve:
1. Keep the "data" partition (primary) intact and carve an ideal partition layout for both the OS with separate /boot, /tmp, /home, swap (and may be for /usr???). Also may be I can share swap?
2. How do I go about using LVM and is it recommended for this case? What would be ideal locations for each partitions and sizes? I already used 100 GB for "data" so now I want to keep 60 GB for Oracle Linux (and Oracle DB for which I will again make few sub-partitions) and remaining will be for Kubuntu.
Well, I am not sure if this is the right place to ask these questions but since I can see very knowlegeable top contributors here that are willing to help novice users I thought of posting these questions.
I would really really appreciate if someone can provide me rough draft of partition scheme in my case considering the sub-partitions needed for Oracle DB. I went thorugh number of forums and documentations to come up with solutuion and finally thought of getting help after much confusion.
I really need to carefully plan this time because it's third time I am doing reinstallation from the scratch because of poor plan I followed previously.
Thank you very much in advance and please let me know in case more information is needed from my side.
Regards,
Ramesh

I accidentally downloaded source DVD "Oracle Linux Release 5 Update 2 source - DVD" instead of installable ISO image. Is there anyway I can compile it to make bootable ISO image?Google will be your best friend for such a question, for instance, "Creating a Custom centos Linux bootable ISO Image". There is no need to duplicate the effort. I recommend you download the correct installation DVD, e.g. 5.8
Thing is I already have Oracle Linux 6 Update 2 (the latest) installed on my machine in dual boot mode so I dropped the idea of installing version 5.2. As per the documentation 11gR2 was not certified earlier on Linux 6.2 so I thought of installing 5.2 but it is not necessary now.So you don't need to install 5.2 anymore, but you want the information how to compile a installation DVD from the 5.2 source anyway?!
I have another couple of important questions and need guidance from the experts over here. I am not sure if it is appropriate to open a new thread but for now I am posting them here.Questions may be important for you, but not necessarily for others. No one will complain if you create a new thread for particular questions or subjects. It is better to separate your topics and questions rather than creating a multi-mega thread, which does little to help anyone else but you. It means more work on your end, but it will be easier for anyone to participate or answer your questions, and it will allow you to better award answers.
Regarding your partitioning questions: It is generally difficult to address such topics in a forum. You are asking for a book of information. My advice is to drop the old fashioned concepts of dual or triple boot options and install Oracle VirtualBox instead. It will make all of these questions obsolete and you can use whatever defaults when installing your virtual machine guest OS. Its a far more superior way of dealing with multiple operating systems on one and the same computer.
I am using Ubuntu 11.10 Desktop.
I need to urgently install Oracle 11gR2 on it.For what it's worth, if you can combine the two source below you should be able to install and run 11gR2 on Ubuntu 11.10.

So I made the Switch, but.... (this is a long a read)

Hi Everyone,
I've been debating to switch for the past year now, and been visiting all the Mac forum sites. After all the hype and fun of Macworld, and after watching Steve's keynote on Tuesday, I decided it was the right time to buy. I bought a 12" iBook G4 stock from an Apple Store (not the closest Apple Store, but the second closest, which will be a factor as you read along), along with the Apple Care plan and a .Mac account.
3 days ago I booted up my iBook and was amazed at what followed: cool 3-D boxes flipping around, "welcome" in a variety of languages, etc.... I went through the complete process, then upgraded all the Apple software and started exploring Finder as well as a few aps. Around 30 mins into the experience, I noticed that the trackpad wasn’t really responding to my touch as the trackpad does on my friend's powerbook or the store's display iBook (by this, I mean that with my finger pressed on the trackpad, the cursor arrow still lagged a bit as I moved my finger; I even changed the speed of the cursor arrow under Preferences, but still experienced the lag). I thought nothing of it. "New computer, cold feet," I thought. "It will warm up soon enough."
I installed the driver for one of my compatible HP printers. Then I started to mess around with Safari. That's when I noticed that the ibook was bit slow to open Safari (the only things that were opened at the time were Finder and Dashboard, so I thought 512 gigs of ram would be enough to handle 3 aps at once....right?)..... played around with Safari, then closed it.
I went to open my Hard Drive, and doing that was also a bit slower than when I first opened it.
I then went on to install software for another compatible HP printer. At the last step, I got my first "spinning beach ball", and that ball kept spinning for minutes. At least 10 minutes. So something was not right. Using the key commands for Force Quit, the Force Quit Box popped open. But every time I tried to move my finger to force quit the application, the arrow cursor did not move. So I rebooted, pressing the power button.
Once the system rebooted, the final installation step for the HP printer appeared on my desktop. So I went through the same steps. Again, spinning beach ball for another 10 mins. Again, tried to Force Quit. Again, the trackpad failed to sense my movement, leading me to believe that the Fore Quit window froze, too. Again I had to reboot holding down the power button. (Am I wrong to think that the Force Quit box should respond as quickly as Window’s Task Manager box?)
Once it rebooted, I was able to uninstall the HP software, and I sent it to the traschcan. To end the day on a good note, I decided to move some photos and set up my desktop background pic. I am totally in love with the idea that my desktop background image will change everyday!
so day 2..........
Started off much more promising than Day 1. I installed office 2004, but had a bitchy time trying to install VPC. After realizing that I really don't plan to use VPC on this machine (it's free software b/c my school has an agreement with M$), I just uninstalled the set up assistant. I was able to set up a wireless network in my lab via the Airport Extreme I got a while back. No problems there.
I went out to buy a Logitech wireless mouse (the one that's Mac compatible and boasts " up to 1 year" battery life). Went home and downloaded the driver for the mouse. No problems with the cursor movements at all; in fact I had had no problems with the cursor movements all day. I thought that ibook got over the problems it had the day before. Man was I wrong....
I installed Firefox and Palm desktop. No problem. Then my friend---the one with the powerbook--- called to see how I was doing. He then helped me set up iChat. Then he totally freaked me out when he "called" me using the voice feature. I was blown away.
But about 20 minutes in, I couldn't hear him anymore. Then iChat froze while I was having a total of 3 buddy conversations. At this time, iChat was the ONLY ap open, so I was little confused as to why my desktop froze again.
Again, I tried to Force Quit using the key commands, and again, the Fore Quit Box did not respond to my movements. So I rebooted holding down the power button.
Once the system restarted, I noticed that the cursor arrow started to lag in time compared to my actual mouse movements. I double checked by using the trackpad, and low-and behold, like the night before, the cursor was slow to my finger movements.
I decided to shut down for the night and hopped back onto my PC to converse with my powerbook friend as what to do next.
Then it hit me: my HP laptop was being MORE reliable than my new ibook!
Today is Day 3. To my disgust, my first post on AppleNova is not about how great my new ibook it, but rather a post for help. It's a little ironic that I am typing this up right now on my HP, not my iBook!!!
so, any advice? is this the "routine" experience for breaking in an Apple product? Where might have I gone wrong? Or is this the computer equivalent to a "lemon" car?
should I use the Deluxe disc that came with the AppleCare package? Or should I just call Apple Care anyway? OR should I just march back into the AppleStore and demand a new machine? If so, the apple store I bought it is 30 miles away, but the nearest Apple Store is 12 miles away (can I return it to the nearest Apple Store, even though that it is not the store I bought it from?).......
sorry that this is a long thread, but from reading the posts from this forum during the last 6-7 months, I got the impression that this community was all about helping other Mac users, and I'd like to be part of the Mac faithful even if I'm having a bad first time
I've heard everything from "it could be HP drivers" to "take it to the Genius Bar" to "reinstall Tiger" to "Use the Hardware Check".........
iBook G4 Mac OS X (10.4.4) bought this brand new iBook --my first Mac--- this weekend

Frist tip, after installing software updates (I assure your machine started off with 10.4.2 and when you first used it, you were promted to update to 10.4.4.), go into the utlities folder (under applications) open disk utlitity and verifity and repaire disk permissions, this will greatly boost preformace and may fix your problem. (In fact do this once a week) Go ahead and run the Techtool (Applecare hardware test CD) and check for any problems. If these come up with nothing, I'd call Applecare and tell them what is happening. Applecare will cover you at any Apple dealer and some Apple resellers as well. Going elsewhere will kill your warrenty BTW.

SL and Boot Camp - new installation

Just purchased another mac book pro and upgraded to snow leopard. Need to install a windows vista and MS office using boot camp. Need advice - what size partition should I give to the windows partition? System HD is 250 GB. This is a complete office install with project and visio. Only to be used as needed so no gaming, itunes, etc.
This is a spare system for me and the mac environment will be my primary working environment.
Any advice on partition size? Thanks.
Also - if this should be posted elsewhere please reply with the correct group!

Go 32 Gigs, its plenty of room for Windows and your windows only office apps.

Can we have everything about Oracle in one drive?

Hello, everybody,
We got a backup database server. Since it is just for backup, we don't want to spend too much $ on this one.
My question is: can we have everything about Oracle installled in the same drive?
It means that Archive, Redo Logs, Oracle system itself, the data, etc will be loaded into one single drive.
Is that OK?
Any input will be highly appreciated?
thx.

It means that Archive, Redo Logs, Oracle system itself, the data, etc will be loaded into one single drive.Here's a piece of advice though, partition it to look like your prod server... it will make life much easier when moving datafiles.

Best hardware for oracle

I have oracle database that contain more than 70,000,000 recoreds
my oracle is 9i .
my os is microsoft windows server 2003 .
which kind of hardware i need for having good performance ?

I can advice using partitioning to improve delete operations if it is possible.
From my experience, SQL tuning is better then increasing CPU, memory, even better then RAC... if it is possibel too :)
Finally, for hardware advice, you should monitor sys.v_$system_event in order to determine what is the wait event most painfull.
If it is an event related to I/O, then i will suggest improving I/O performance, by spreading IO to many more disk. How much working HD Head you got, that much performance is you have. Also you should configure your storage LUN and partitions in order to balance I/O on all disks.
If it is an event related to memory, then better to add much memory as possible and try to play with memory parameters. However, determining what consumes memory is impotant. Let say if you have many more sessions consumes little memories, then maybe using pooled connection will solve your problem.
Good luck

How to create Delivery from VA01 wich split on the basis of line item count

Hi Frnds,
I have this requirement where I have to split a single sales order into multiple deliveries whenever the line items count exceeds 10.
Kindly advice if there is any routine/ any exit for this OR any other soln to this...
Note : Splitting only takes place when the Line items count exceeds 10.
for eg : In VA01, for a sales order having line items
01, 02, 03, 04, 05, 06, 07, 08, 09, & 10 ---> One delivery
11, 12, 13, 14, 15............................ 20 ---> second delivery
Your help will be truely appreciated..
Thanks,
Kamal Sehrawat

These are called copying requirements. If you open VOFM, you will understand better.
The routine is a 3 digit number which corresponds to one particular scenario. There are many standard routines for each scenario. Ex : sales orders, deliveries, partners etc.
There are 2 cases:
1. copying the data from one scenario to other. Ex: orders to delivery, delivery to billing etc
2. Moving the data while creation.
You can choose anything which depends on your scenario.
To code, copy the routine and create a custom routine. Select the routine and Press F5 (Second Icon to see the source text) to write the code. You can write/modify the code in the copied standard include it takes.
If the standard routine is not suffice, you can also create a new custom routine which starts with 9XX.
You need to explore more to understand better.
Thanks,
Vinod

Backing up HD and Panther upgrading step by step request

new to forum, just want to ensure I do everything right..
I've had and used my iBook for 5 years now and I believe have been running 10.2.8 for the majority of that time.
I have the following items-
-iBook (meets requirements)
-WD My Book Pro edition 250GB
-Panther upgrade discs
and would like to do the following procedures-
-back my current HD onto the external drive (I do not want to lose my music,photos, and mail when I upgrade)
-upgrade to Panther
-use new OS with music, photos, and email intact
I've read through the discussions for tips, but I would appreciate a simplified step by step walk through if someone would be so nice... I have zero experience backing up, running disk repairs and permissions stuff, etc. so any steps that are helpful along the way are appreciated.
also I believe I need to format the WD My Book to run properly in 10.2.8 before I can backup HD prior to upgrading..? sound right..?
forgive any terminology mistakes.
thanks,

Welcome to Apple Discussions.
If I may expand on roam's very comprehensive response a bit, just by way of fleshing it out.
You said you have an external HDD, but you did say whether is was Firewire or USB or FW/USB. If you want to make a bootable clone you need firewire.
As roam indicated you will need to format and partition the HDD before you can clone to it. Dr. Smoke's FAQ Backup and Recovery has excellent advice on partitioning.Now to
Formatting, Partitioning Zeroing a Hard Disk Drive
Warning! This procedure will destroy all data on your Hard Disk Drive. Be sure you have an up-to-date, tested backup of at least your Users folder and any third party applications you do not want to re-install before attempting this procedure.
Boot from the install CD holding down the "C" key.
Select language
Go to the Utilities menu (Tiger) Installer menu (Panther & earlier) and launch Disk Utility.
Select your HDD (manufacturer ID) in left side bar.
Select Partition tab in main panel. (You are about to create a single partition volume.)
Select number of partition in pull-down menu above Volume diagram.
(Note: 1 partition is normally better for an internal HDD. External HDDs usually have more than one)
Type in name in Name field (usually Macintosh HD)
Select Volume Format as Mac OS Extended (Journaled)
Click Partition button at bottom of panel.
Select Erase tab
Select the a volume under Manufacturer ID (usually Macintosh HD).
Check to be sure your Volume Name and Volume Format are correct.
Select on Security Options button (Tiger) Options button (Panther & earlier).
Select Zero all data. (This process will map out bad blocks on your HDD. However, it could take several hours. If you want a quicker method, don't go to Security Options and just click the Erase button.)
Click OK.
Click Erase button
Quit Disk Utility.
Now your HDD is ready to accept your clone. Dr. Smoke has a preference for Retropect which I have found diffcult to use. SuperDuper will do an excellent job of making an exact backup of your HDD on the external drive.
Your computer is already connected to the external HDD.
Launch Super Duper
Select the Source (your iBook) and the Destination (external HDD)
Click copy, and confirm.

Trying to install SL on a new hard-drive for my iMac, when asked which disk to install on it gave me no options, i followed advice from another forum and created a partition, now can't boot from the new drive at all. Help?

I've had **** with my iMac, the hard-drive failed so i replaced it with a new 1TB Samsung drive. Then when i tried to install SL from the install disk, all went to plan until it asked me which drive i wanted to install it on, where it came up with a box where my options should have been, but instead it didn't give me any options to install it on any drive i.e. it asked which drive i wanted to install it on but no drives came up to select.
So i followed the advice from another forum, look at the 'Extended Hard-drive preparation' response
( https://discussions.apple.com/message/10576009#10576009 )
After following these instructions i have now got a new partition, but when i restarted my computer to install SL on the drive, the option to boot from the drive is now not available, now i must boot from the install disk, whereas before i was able to boot from either the install disk or the hard drive. The hard drive is still visible in disk utility as it always has been, but i am now unable to boot from it, let alone install SL.
Please help my iMac has been broken for months and i've been trying to fix it for so long and am getting problem after problem. Thank you!

Hi db2
That off the shelf MS-DOS / FAT-32 drive needs to re-partitioned GUID Partition Table / Mac OS Extended (Journaled) before you can install OS X and Startup your Intel iMac from it.
1. Boot from your original install or retail SL DVD and open Disk Utility.
2. Highlight the new HD in the list of drives and select the Partition tab.
3. Under Volume Scheme select 1 Partition and click on the Options... button.
4. Select GUID Partition Table in the drop down window and click OK.
5. Set the Format to Mac OS Extended (Journaled) and click the Apply button.
6. Once thats done, then you can do a clean SL Install, Restore from TM , your old HD or Bootable Clone.

Advice on abap routine in update rule

Hello Experts,
I have written a routine in update for replacing some 'not allowed characters' with space.
The abap code is correctly working as a standalone program as is giving the correct results.However,
when i write the same code in update routine, no change takes place in data, i.e. 'not allowed characters ' are still there in my data.
Please advice if there is any special change that is to be made while writing the code in update routine.
if STRLEN( CHECK_TEXT ) <> 0.
    ALLOWED_SPECIAL_CHARACTERS = ' &()*+,-.:;<>=?!@$%~'.
    ALLOWED_CHARACTERS = 'ABCDEFGHIJKLNMOPQRSTUVWXYZ_0123456789'.
      TRANSLATE CHECK_TEXT TO UPPER CASE.
    strl = strlen( CHECK_TEXT ).
    IF CHECK_TEXT CN ALLOWED_CHARACTERS.
       WHILE len1 LE strl.
        IF CHECK_TEXT+len1(1) CN ALLOWED_CHARACTERS.
        CHECK_TEXT+len1(1) = '.'.
         ENDIF.
       add 1 to len1.
      ENDWHILE.
    ENDIF.
Regards
Priyanka

Thanx a lot for a quick reply .
The main problem that we are facing is this simple code is working fine if it is executed as a report program but if no changes takes place when i move this same code to my update routine.
(1) According to you i should write this routine in the start routine instead of update rotuine ??
(2) how would function module help in my case...kindly elaborate a it.
Here is the complete update rotuine.
data:
len1 TYPE i value 0
R_TEXT(60),
CHECK_TEXT(60),
R_TEXT = COMM_STRUCTURE-/BIC/ZC_NTXT1.
if STRLEN( R_TEXT ) <> 0.
ALLOWED_SPECIAL_CHARACTERS = ' &()*+,-.:;<>=?!@$%~'.
CONCATENATE 'ABCDEFGHIJKLNMOPQRSTUVWXYZ_0123456789/'
              ALLOWED_SPECIAL_CHARACTERS
              INTO ALLOWED_CHARACTERS.
CHECK_TEXT = R_TEXT.
TRANSLATE CHECK_TEXT TO UPPER CASE.
strl = strlen( R_TEXT ).
IF CHECK_TEXT CN ALLOWED_CHARACTERS.
      WHILE len1 LE strl.
      subs2 = CHECK_TEXT+len1(1).
        IF subs2 CN ALLOWED_CHARACTERS.
        CHECK_TEXT+len1(1) = '.'.
         ENDIF.
        ENDWHILE.
endif.
    ENDIF.
RESULT = CHECK_TEXT.

Need advice for erasing disk/partition

Hey everyone,
I currently have a Mac Pro that is partitioned with both Lion and Snow Leopard. I'm trying to un-partition the computer and wipe it clean - thinking of updating to Mountain Lion but would like to stay with Snow Leopard for now if possible.
I erased the Lion partition by using Disk Utility but now I'm wondering what the best way to clean the computer is.
When I go into Disk Utility and go to "Erase" it won't let me select Snow Leopard. I went to Disk Utility Help and it says "To erase your computer’s startup disk, you must start up from another disk, such as a Mac OS X installation disc."
This means that I need a hard copy of an OS installation disc before I can erase/clean Snow Leopard? Is it possible to buy the disc from Apple or are the OS systems only available for download through the app store now? Are they only selling Mountain Lion?
Any tips or advice here is greatly appreciated!
Thanks!
~ Hugo

What is wrong with your 10.6 Snow leopard installation that it needs to be "cleaned"? Macs generally do not need to be cleaned, as they do not accumulate filth.
How did you get 10.6 snow Leopard onto your computer in the first place?
What model mac Pro ?

Installing OSX Lion on OSX Mountain Lion Partitioned drive-Help/Advice please

I have my late 2009 27" iMac running OSX 10.8.5 Mountain Lion but need to install OSX Lion on a separate partition and would appreciate help / procedure advice as to how to do this safely.
I need to do this because I have found that running FCP7 Studio under 10.8.5 there's some missing or odd keyboard and Timeline functions that were not there under Lion and FCP7 is a valuable tool for me that I don't want compremised. I'd like to be able to run FCP7 / Lion in a separate partition on the iMac.
I have partitioned the HD and there's about 700gigs of clean space on the second partition. I also have downloaded from my account on the App Store a copy of Install Mac OS Lion to my Applications folder and I also have a copy of it on a USB Thumbdrive.
So, what do I do now to safely install the second OS without messing up everything else that's on the machine in the prime partition?
Thanks!

Ok….I managed to work it out…..Installed Lion on the second partition, working fine now.
