HDD Read/Write Issues

Hi,
I'm currently using a Macbook Pro 13" Mid 2009 with 4GB RAM and a Western Digital WD500GB Scorpio Blue HDD. Untily today everything was fine, but now my Macbook on Mac OS X 10.6.4 is horribly slow. AJA System Test showed me the following, I guess that's what slows down the whole notebook...

System Profile looks like this
http://skitch.com/epij/dhug1/systemprofile
But actually I don't know wether it's really the HDD or not, because Win7/Bootcamp is just running fine (about 45MB/s Read/Write).
Any advice would be great. (btw. I tried formatting the Mac OS X partition and installing 10.6.4 from scratch) And please excuse my bad english, it's not my native language
Thanks, Epij

~/oradiag_$USER/.. and "Directory does not exist for read/write" issue

Hi.
Recently I've discovered that ADR was creating a folder in one of ours Oracle 11.2.0.1 server, in the users home like ~/oradiag_$USER/.. The problem is that this logging files dont stop growning, and they are filled only with this lines:
Wed Apr 11 13:40:06 2012
Directory does not exist for read/write [usr/oracle/product/11.2.0/log] [usr/oracle/product/11.2.0/log/diag/clients]

Directory does not exist for read/write [usr/oracle/product/11.2.0/log] [usr/oracle/product/11.2.0/log/diag/clients]
etc
I've searched around internet about this issue all that I've found is a "workaround" by creating those folders. And yep, it works, it stops growning.
Then I checked the others servers that we have, and the problem replicates in some servers with the same Oracle version.
My question is: Why this? Why in some servers ADR is looking for that folder? That folder didnt exist in any of them, but only some servers tries to read/write on it (or, at least, log it) What parameter relies on it?
Regards.

Recurring Read/Write Issues (1 year now) - NEED FIX

My Macbook Pro Mid-2009 had a hard drive issue -- lots of weird errors, unclear. Essentially, switched out the hard drive for a brand new one, did a clean install on a 1TB 7200 RPM Hitachi HD. Continued to throw errors when trying to read/write so I was told the hard drive may have been defective out of box.
Since then, have replaced it with another 1TB 7200 RPM, then a 512GB 7200RPM and now finally a 320GB 5400RPM. ALL CLEAN INSTALLS. Still getting errors -- at this point, I'm being told when trying to Download Chrome that there is no room available when in reality there is ~300GB free, and when trying to change permissions to the Downloads folder am seeing "An unexpected error occurred (error code -50).
I've been to the Mac Store ~8 times about this already and still no fixes. One suggestion was maybe the Hard Drive Cable is broken? I had it replaced in 2012. Thoughts? Is there any way to check this?

Hi,
paramErr
= -50, /*error in user parameter list*/
It's not formatted Case Sensitive is it?
Sounds like other HW problem like RAM, Logic Board, cable, etc.

DV4-1125nr DVD Combo Reader/Writer Issue

Hi,
First, try the automated fixit from Microsoft on the link below.
Windows 7
Vista
Check if the drive is now working.
If the drive is not working, from the Start Menu, open the Control Panel and click on Device Manager. Click to open the IDE ATA/ATAPI Controllers. Right click on the first channel and select uninstall. Do not delete drivers if asked. When uninstalled repeat the process for each channel. Also if an ATA controller is listed, right click and uninstall this, again not deleting drivers if asked. Then open DVD/CD-ROM Drives. Right click the drive and select uninstall. Do not delete drivers if asked.
Reboot the PC and let Windows reinstall the devices. Check the drive again.
If it still isn't working, run the automated fixit from Microsoft on the link below again.
Windows 7
Vista
Next, from the Start Menu, open the Control Panel and click on Device Manager. Next click to open DVD/CD-ROM Drives. Right click the drive and select uninstall. Do not delete drivers if asked. When the device has uninstalled click on the 'Scan for Hardware Changes' icon ( usually just below Help on the toolbar ). Let windows reinstall the drive and see if it now works.

Weird HDD Read & Write Speed

Been running some tests on my relatively old editing machine as i try to squeeze the most out of it before i upgrade within the next few months. I was quite suprised to see these speeds for the G-Raid:
Raid0 2x750GB WD Green NTFS:       W158.4     R159.6
Single 2TB WD Green NTFS:              W77.6       R78.0
G-Raid 2x1TB Esata ExFAT:               W56.8       R134.9
Any ideas? System is as follows:
Q9550 @2.83ghz
Asus P5q PRO
8GB ddr2
250gb seagate 5400 system drive
Asus 670GTX 2GB
I appreciate that the WD Green's are crap, the system was built well before i was into editing, i'll be steering clear of them when i get around to my new build.
I'm trying to edit 4k scarlet footage and things just aren't going very well for me, understandably. I have been using the g-raid as the media drive so far and the raid 0 as the cache drive, will i see any performance increase swapping them over?
Cheers

Remoteman,
Regarding the R-RAID, your #'s are way low. You can try:
- format to NTFS
- update motherboard drivers and firmware
- make sure windows caching is turned on for your eSATA drive letter and that buffer flushing is turned off
I will assume that you have CS5, 5.5, or CS6 since you are trying to edit 4k Scarlet!
No matter what you do with your drives, your Q9550 processor, which was introduced in early 2008, is pretty lame compared with newer CPUs.
Make sure your playback window is way dubbed (i.e. 1/8 res) down and "render all" before you try to work on your timeline if you really need to nurse your old system along with Scarlet.

Jim

Read only issue

It's read write on the laptop via router / network.
But when open now get this new message:
File is being modified by Kevs, open as read- only or choose to be notified or altered when available.
These network/read write issues never seem to end! I'm wiped out, any ideas? thanks!

Can't Read/Write to External HDD-Permissions Problem

I have external Seagate HDD, formatted as FAT32, connected to Airport Extreme Base Station. I am unable to Read/Write to this Drive because Finder says I "Don't have permissions" to do so.
Following are details that may be important:
1. I was able to read/write to this drive under Leopard but lost the right under Snow Leopard, after upgrade to SL.
2. In Airport Utility, I set up (2) accounts for the External HDD, "Dad" with "Read/Write" access and "Mom" with "Read" access only. I have Guest Account privileges set to "Read Only". It has been this way for (2) years.
3. Under "Get Info" in Finder, the only account listed is "everyone" with "read" permission only (this is same as Guest Acount in Airport Utility). I am unable to add new accounts because I get error message "The account name is not valid" even though I am using the account name that I am logged in under.
4. I can change the Permissions on the "everyone" account (in Finder) by changing the permissions on the "Guest Account" in Airport Utility. When I do this, "everyone" in Finder now has "read/write" access but my two accounts, "Dad" and "Mom still don't show up in Finder.
5. I also upgraded internal HDD to 1Tb and used Restore from Time Machine. I hhad problems with the restore and did new install of Snow Leopard.
Any ideas on how to make Finder show the two accounts I have set up in Airport Utility?

My apologies for bumping this but I still don't have a solution...any help would be greatly appreciated!

Lion server file sharing issue with windows API read/write ini file (GetPrivateProfileString)

Hello,
I try to config lion server as file server for a windows application we use at work. All other computers are windows 7 or XP, lion server is the only mac. I choose lion server because it's size, quality and personal love of apple products.
10.7.2 lion server's samba file sharing works almost perfectly with all my windows machines, I can copy, delete, modify any text files or office files without any issue, but the most important windows application for my business doesn't work with samba file sharing. After some digging, I found it is because windows program can't read or write INI file stored on lion share. Windows API GetPrivateProfileString always returns empty if the INI file is store on lion share.
You can download a small application for read/write windows INI file from codeproject.com to test this problem:
http://www.codeproject.com/KB/files/ini.aspx
I can open/edit the in file using any text editor without any problem. The only problem is with those windows APIs. ACL is turned on for my lion share and assigned "delete" rights to samba users.
I install samba3 on the same server; it works perfectly with windows API. My windows program also works. Looks like there is something wrong with lion server's sambax.
I'd prefer to use built-in samba even I have samba3 working. Built-in samba is very immature right now, but considered how young it is, I will give apple some time to make it mature.
Does anyone have same issue or knows how to fix it?
Thanks,
Michael.

All the memory is fine. The server rarely if ever goes down when there are only around 10-12 users connected. When there are 20+ users connected and working heavily it goes down often. When I say working heavily, I mean they are transferring huge files to the SAN (100GB+), sometimes 5 at a time per user, and there are a bunch of others who are reading large video files at a minimum of 220MB/sec from the SAN.
Though this worked on Snow Leopard without any issues, Lion just doesn't seem to be able to handle it. The odd thing is, on Snow Leopard there was only a single 1GB ethernet connection to a NAS system, whereas with Lion we have a much more powerful machine with a 6-port 10GB ethernet card and a 4 lane 8GB fiber card to a true SAN. You would think that the newer scenario with Lion would handle far more users with ease.
So far, very disappointing with regards to Lion's file serving performance.

To have great read/write performance, do you have to save all programs onto the SSD or can you save programs onto the HDD?

if I want to use the fast read/write speeds of my SSD, do I have to save the programs (Final Cut Pro X, Adobe After Effects, Microsoft Powerpoint, Steam, Counter-Strike, etc) onto the SSD? Or can I save all programs onto a 2nd drive which would be a HDD and still have fast speeds WITHOUT storing those programs onto the SSD? My 2012 mid Macbook Pro has a SSD as its main bootup drive and will be getting a 2tb HDD to replace the optical drive.
Any advice or comments is greatly appreciated,
Thank you!

FPGA Read/Write Control Issues

Hello all! Rather new to using FPGA, but I have an interesting issue that's popping up.
Currently pulling in RAW voltage data from a set of sensors (Pressure Transducers, Load Cells, etc) through a cRIO DAQ. Have the FPGA file setup to pull in that data already and have the main VI and all the sub-VIs working just fine.
What I'm trying to do is save the raw voltage data (TDMS files) on the lower level and the convert and display on the upper level so that I don't have to convert and save (speed up saving data). So that leaves 3 distinct levels/sections:
On FPGA that pulls in the raw data
On FPGA that saves the raw data
Main VI that does all the controls/conversions/displays etc.
Number two is where I'm having an issue. I want to save all the data in parallel so I'm creating a save FPGA for each I/O device (8 Relays to command solenoid valves, 3 Pressure Transducers, 1 Load Cell, 4 Thermocouples). To do this I want to create a separate VI for each device (not sure if that's a smart thing to do).
The issue I'm having is when I use the FPGA Read/Write control to read in from the Target and save to the TDMS. When I only use a single FPGA target reference the lines are broken, but as soon as I switch to two targets, it now works.
Any reason why it might be doing this? Any ideas/suggestions at all on how to go about setting this up in general?
Thanks!

Could you take a screenshot and post this part of your code? I'm having trouble understanding what you are describing.

HySoR,
You might check the documentation for "data" terminal of "TDMS Write" (http://zone.ni.com/reference/en-XX/help/371361H-01/glang/tdms_file_write/). One DBL element is not accepted, but 1D DBL array is accepted.
data is the data to write to the.tdmsfile. This input accepts the following data types:

After reinstall, permissions issues even though they say read-write for owner

So I spent all day yesterday rebuilding my system after a power surge from a tripped breaker fried my old hard drive (so much for surge protectors).
Now when I try to register a software plug in, I get an error saying "Access denied. Please check permissions on /Library/Preferences/ [the software in question, it doesn't matter]".
And then, with Safari, when I try to access any website that requires Java applets, I get an error saying that the applet won't load properly, even though I've updated to the most recent version of Java. I'm pretty sure this is because the Java applets are not being allowed to write data to my /Library/Preferences/ folder (or maybe just any folder in the /Library/ folder).
When I run Disk Utility and repair permissions, I'm getting the exact same messages every single time, so even though it's saying the permissions are getting repaired, clearly it's not saving those repairs.
I'm 99% sure that this is a permissions issue following the restore from a previous Time Machine save -- I've seen this before and found a fix involving Terminal commands, but I can't for the life of me find the fix anymore.
I have temporary workarounds for the moment (though it's kind of a pain to have to re-register this software every single time I open the application, and I can have co-workers access the websites that require the Java applets to work, but that's inconvenient for all around), so it's not a pressing issue, but any help tracking down what Terminal commands I should use to solve this issue will be greatly appreciated.

Found the solution...basically the permissions are not automatically cascaded down to sub folders and files so you have to do the following... modified from https://discussions.apple.com/thread/2743520?start=0&tstart=0
On the folder that you would like to change, select the Get Info and then click on the cogwheel at the bottom of the Get Info dialog.
Click on the menu pick "Apply to enclosed items ..." and confirm the warning message.
Then the same read & write permissions are applied to all the subfolders of the selected folder.

G710 hard drive read/write speed

Hello,
I have a brand new Ideapad G710 with 1TB Serial ATA 2, 5400rpm with advertised speed of 3 Gb/s (= 384MB/s).
I am running Windows 7 ultimate x64 with SP1.
When I test hard drive read/write speed (I used CrystalDiskMark) I get results of about 100MB/s, which is 3-4 times slower than it should be.
I am not running any resource heavy applications (Resource monitor reports Disk I/O to be 0 most of the time in idle state). I have 3 partitions, each with 16-32GB paging file size and all are >90% empty. All partitions have been defragmented before testing.
Is this normal? Are there any lenovo drivers or utilities than I might be missing or that can slow/speed this?
Solved!

hi Daew,
Welcome to the Lenovo Forums.
The results that you got while running CrystalDiskMark is normal. The SATA 2 (3Gb/s) that you mentioned is actually the SATA interface support, not the actual read/write performance.
If you have a Seagate HDD (eg. ST10000LM024), check these specs
From the above specs, the unit has a cache that has a read/write max speed of 145 MB/s but there are environmental factors and power requirements to get this speed (eg. read/write speed on AC power is differente from battery power).
AFAIK, if this is the specs that is design for this drive, there's no way to speed it up.
If you're planning to upgrade in the future though, you can get an SSD for faster read/write.
Regards
