Handling error code -8003 in Mac OS X?

"The operation can't be completed because an unexpected error occurred (error code -8003)” . The warning in other words may sound like this: You don't have enough privileges to perform the delete action.

Secure Wipe OS X El Capitan files with Mac wiping utility

The above code is one of the strange error codes occurring on Mac not letting you trash certain files. In spite of all your efforts in deleting the files from the trash you still find the trash filled with the files. In order to solve the issues the user firstly reacts by restarting the Mac hoping the same error won't be repeated again. However it is kind of hit and trial method which mostly sometimes works but on the contrary it is noticed that even the restart won't work at all.

Reason for error code -8003:

The error states that in Mac OS X you don't have enough privileges to perform a deletion of the file. This may be due to the files are present on an external drive but it is noticed this error bothers files even present on any drives. Another reason for the same error could be that the files present in the trash can are locked.

Possible Solutions for error code -8003:

• Open the trash from the finder to view the entire files present in the bin.
• Hold down the Option key and Click “Empty Trash” to do the rest of the job.
• Problem still not solved then attempt to delete the files through “Secure Empty Trash”. Many of the Mac users may not know but this option deletes the data from the Mac hard drive permanently through wiping algorithms. The spaces of files once deleted are immediately overwritten by meaningless data to avoid recovery of files at later point of time.

Solution through Terminal:

• Goto Applications->Utilities and click Terminal icon to open.
• Upon opening the terminal type the code sudo rm -rf ~/.Trash/ and hit enter.
• Above measure may sound sufficient to tackle the error code-8033. However, if all of the above measures fail to solve the issue then there are utilities which can be used to get rid of the trouble. You can select a wiping utility to erase the files, even locked files through right-click and selecting the files for permanently deletion.

How can I fasten my old Mac OS X?

At a certain point we have asked this question to ourself and many times we haven't been able to answer it correctly. When I bought my first Mac Mini home I felt like sitting next to a home version of a super computer. It was that fast and advanced. But a year has gone by now and today I feel like sitting next to a sluggish OS X. So what happened to my Mini during a period of year? Out of 365 days if I was able to work on say 300 days then I would have 10000+ times performed read/write operations on hard drive, install & uninstall plenty of wanted & unwanted applications. I truly belive now my Mac hard drive needs an over-hauling and for that I am going to implement several tips and will also take the help of a tool if necessary.

Test Machine Specifications:

Mac Mini OS X 10.7.2 Lion
500GB Hard drive &

1) Starting with Mac Restarts: My Mac remains ON for almost the day and during the first half of the day I don't find any of the speed complications. But after I had my lunch and I make my way back to the machine I certainly feel sluggishness playing around the OS X which is very undesirable. To fix this time-being sluggishness the OS X needs to be restarted. So, close down all the application and restart the Mac for further work. You will definitely feel a good difference. The reason behind a restart is simple: because many of the already on applications consume lots of memory space and makes the OS X to respond even slower.

2) A Clean Desktop looks good: Not only a clean desktop gives a refreshing feeling but it also help the system get rid of sluggishness that is caused by plenty of desktops icons.

Image Source: Cult of Mac

The above image is what an example of a cluttered desktop of a Mac user. Hopefully you and me don't prefer to have a desktop like the above image. Literally, It require even less than 15 minutes to organize a desktop and manage the unnecessary icons.

3) In any OS X, you can set the login items in the System Preference menu. Doing that makes the system to start the set items once you login into your Mac. Other than the usefulness of startup items in System Preferences, the same can be the cause of OS X's poor speed. If anyhow, some unwanted items get added to the list then it will certainly consume more of the CPU usage which in turn slow down the system. We as a user never know, after a new software installation the items might add themselves to the login-itmes which now needs to be moderated on regular basis.

4) Are Widgets really a necessity: Installing newly launched widgets and applications are one of the famous activity done by many of us. Widgets entertain us a lot but the fact can't be denied that the same of them eats up good amount of computer memory resource in the background. Here, I do not meant to get rid of all the widgets you have ob your Mac but cutting down their numbers, removing unwanted widgets will definitely help the Mac have some more of the space that were early consumed.

5) Time Machine needs to be schedules: I have gone through several forums where users are dissatisfied with the slow time machine back up process. Here's how you can set the scheduling of a time machine back-up:http://osxdaily.com/2012/02/02/change-the-time-machine-backup- schedule/. This will help you to take backup during non-working hours and would not halt when you sit on your system.

6) Cleaning a hard drive: In OS X, many of the settings have to be changed to grab some more free space. Similarly, hard drive is a huge segment where we can regain Gb's of free space by performing the below following activities:

• Wiping out the pool of stored caches and temporary files from volumes,
• Removing useless applications from the hard drive which are not accessed for months and does not add too user's productivity.
• During a software installation, many of the languages get installed on the system and other than the default language all of the rest are unnecessary. Removing these unwanted packs of language files can make the OS X take full advantage of the free space.
• Duplicate files and data are a complete mess which needs to be removed at first glance. Not always, but many a times same file or software is saved on different logical partitions which is a burden on the hard drive. Here, the user can also choose a cleaning utility to dig out bunches of duplicate files from the Mac hard drive.
• With help of a speed up tool, the leftovers and trashes on the hard drive can be located for deletion.

Before I end this article, I would say that the above tips helped me get the crap cleared from my Mac Mini hard drive and have gained good amount of speed and performance back on Mac. There are plenty of more tips to implement which I would share in upcoming posts.

How to safeguard the private data during a computer repair?

Just in time you encountered a problem with the system and don’t know how to fix it. You make a call to the support and they recommend you to leave the computer in their service station for few days. Isn’t it a general scenario during a computer visit to the service center? I remember when took my brother's DELL Vostro 1410 Laptop to the service center that took it for a whole day and returned me with the ready machine next day. I wondered, although the technician being an honest person doesn't bother to look into your hard drive. But what if someone in curiosity or a person with bad intention tries to access your photographs, images and other confidential data during the repair? If it occurs, this could be very nasty for the user.

I am sharing some of the information through which the user can prevent the data getting into someone’s hand. Here's the process:

• Take backup of the partition.
• To take the back-up use either cloning, imaging.
• Mac users can take time machine backup on an external hard drive.
  

This will ensure that even your hard drive gets tampered during the repair; you still have the access of your data through proper back up measures. But let’s not forget the data is still in open for any third person to gain access. Now what to do with the data that is accessible even during the repair.

• Organize a small data management campaign and prepare the list of private data needs to be secured.
• When all the data files, even the smallest of them is complied, make them write either on a large capacity BD disc, an external drive. If you have server connectivity then it’s too good to store data safe and secure over there.
• If you are a cloud user then use the online data storage facility.
• Formatting the hard drive will definitely erase the data from the hard drive but to guarantee data deletion from the drive one must secure clean it.
• How to secure wipe the data from the system: To do so hard drive needs to be erased using several passes. These passes are provided by the set of wiping algorithms that ensure safe deletion of the data beyond the scope of recovery. Here, Mac & Win users can run a third party wiping software to erase the confidential data through several passes.
  

RAID 5 Data Corruption: Symptoms & Precautions

Since the discovery of RAID (Redundant array of independent disk) Data storage technique, user follows the trends of having mass storage capacity as well as ability to recover his/her data from any failure conditions. The most widely used and famous RAID Storage technique is RAID 5, require minimum of 3 disks and have some key features, such as:

• Fault Tolerance means increase data protection and integrity
• Increase storage capacity
• Faster performance

Many users believe that RAID drive has been made to not fault but in reality, it fails. In most of the cases RAID 5 array become failed or corrupted due to various unavoidable facts. For details, look around the topics mentioned below:

1. When one hard drive attached to RAID servers become failed, eventually the RAID arrays will start to run in degraded mode. After which, other disks in the array will have to suffer an equal stress which results in failure of second hard drive. So, consecutive failure in two drives attached to RAID arrays will leads to RAID 5 array failure.
2. RAID 5 controller failure
3. Any power surges, occurs with RAID 5 controller can malfunction RAID elements, RAID configuration or the hard drive itself.
4. Sometime, in an attempt to rebuild failed RAID arrays, you may enter wrong RAID parameters, which causes a sudden breakdown and complete system failure.
5. Logical corruption such as virus/malware attack, hard drive crash, human errors, RAID partition table corruption etc. Though, RAID Drives are made with fault tolerance which protects only physical failure but could fail in case of logical failure.

You should avoid doing any of the following activities to stay away from any data loss situations:

1. Stop using RAID drives in case of a single hard drive failure. Any remedial actions on such conditions will leads to damage on second hard drive and failed RAID arrays.
2. Don't try to remove or alter any hard drive attached to RAID arrays while system is performing any read/write operation.
3. Always remember or note down the various RAID parameters which greatly helps to successfully rebuild corrupted or failed RAID 5 arrays. The possible required RAID parameters could be :

• Disk Order
• Stripe Size
• RAID Header Size
• Parity Rotation
• Parity Delay

   4.  Do not operate any chkdsk or similar disk checking operation, as this command will run 

        in write mode and heavily responsible for overwriting the failed hard drive data.

   5.  If you've loose any important data from failed RAID arrays, it's advisable to wisely 

        choose any data recovery software.
 
P.S.: To recover data from failed RAID arrays using RAID recovery software, you are 

        also required to enter the correct RAID parameters which I have already described in #3.
