MacPro slows down as adding external FW drives ?

Is it me or my Mac is now slower ? I have one additional 500GB internal drive plus 3 LaCie and one WD external FW Drives and My MAc is sort of "sleepy". I have a feeling that the additional drives are the culprits but what can I do to improve this situation? Thanks.

I would assume trying w/o the 4 FW units would be first off.
Issues with both makes get mentioned from time to time.
Even a bad cable can be problem, or daisy-chaining.
What are those drives doing? going to sleep? used sporadically? latest firmware from LaCie? LaCie FW/USB/eSATA enclosures also have slower than expected performance.
I've run with 4 OWC Mercury FW800 drives, along with 8 external SATA drives running on Sonnet controllers.

PSE 10 system slows down when adding files to catalog

I recently switched from PSE 3 to PSE10 and had issues converting the catalog. I never did resolve those so I decided to start with creating a new catalog in PSE 10. My first session of adding photos worked fine. When I restarted the task the next day, I was asked in participating in making the product better by sharing information about my use with Adobe. I agreed to participate and very quickly noticed that my computer slowed considerably when adding photos from my hard drive. The process still worked but I experienced a dramatic increase in the time it took for photos to be added (e.g. the cursor spins for a couple of minutes while the task is working). I went under my account preferences and opted out of the product participation program but the problem has persisted. I rebooted the computer to see if that would help but it has not. I have turned off all media analysis and both optimized and repaired my catalog and while this has provided some improvement, there are still instances where the system slows down. Now it seems that every other folder's worth of pictures (does not matter how many photos) I add causes this delay.
I appreciate any help anyone can provide in determining why this slow down keeps occuring.
FYI, I am running a new Windows 7, 64-bit system with 8GB DDR-3-1066MHz, and 2 TB hard drive.

Have you also edited the Preferences (Performance) to increase the amount of RAM that PSE can use?
Do you have many background processes running? Having a single HDD means that everything running on your computer has to wait in the queue for disk access.
How many photos are you importing?
What file types are the photos?
How large are the photos?

My macbook slows down after using external HDD

When I use an external drive via usb, my computer really slows down giving me no choice except reboot.
I watched memory usage with activity monitor. Free memory decreases by time and inactive memory increases with the same amount and others don't change much. If I continue using -esp. reading-, free memory comes below to 100MB and then increases a bit -I think it starts paging =other applications' memories= to system disk-, then continues to decrease. Closing the application -that use the external- do not relese memory from inactive to free but ejecting the external does. After unplugging and trying to use the other applications, I face very sluggish performance so that rebooting becomes a better-fast choice. Both NTFS and FAT partitions produce the same result and I don't have any other partition.
If I try to re-read the same file after the external drive stops spinning (sleeps), it does not start spinning but trying to read another file makes it start spining. This makes me think about some -overdone- caching problem, but don't know what causes it and how to turn it off (Tuxero's caching is already disabled in the preferences, although I think it is only for writing only).
I made some research and found nothing specific; they tell to reinstall the os or format the drive -to HFS+ -. What is causing this?
Note: All of my drives are in Spotlight's exclusion (privacy) list and using another usb slot did not change a thing.

Very slow transfer speeds with external hard drives through Firewire and US

Hi All,
My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little. Apple support suggested I post my issue here. Just to make a note, I measured my disk speeds with both AJA System Test and copying files between drives and reading the Disk Activity in Activity Monitor.
I have 3 external drives, all MyBook Premium or Professional, 1x 500GB, 1x 1TB and 2x 1TB in RAID 0. I had them on Firewire 400 and the RAID 0 2TB one on Firewire 800. My transfers on FW were all around 24MB/sec on all drives (much less than what I should be getting with FW400). I then read somewhere that the FW bus on the MacPro uses the slowest speed connected for all FW connections. So I unplugged everything but the FW800 Raid 0 drive and my transfer rate jumped to 40-60MB/sec. This is much better, but still about half or so of what I expect it should be producing from an external RAID 0 setup.
To keep my FW800 backup drive faster, I've plugged the other two into USB2.0. The transfer speeds on both drives are now hideous, around 10-15MB/sec. This is so slow, but I'm not sure what to try to fix my speeds.
The HD's in the external drives are all 7200rpm, and all should be transferring at a higher rate. Do you have any suggestions or ideas? Ideally I'd like to get everything transferring at rates they should be transferring at, but I'll settle with my current FW800 speed of 40-60MB/sec if I can get my other two drives transferring at a non-snail pace.
Is this a common issue? I can't believe I'm the only one plugging multiple external hard drives into their Mac Pro. I hope someone has a fix or solution for this. I'm all ears!
Thanks in advance.

Hi Kappy, thanks for the information.
So I rejigged my setup a tad. My RAID 0 is still FW800, the second drive is back on FW400 on the back port, and the third is USB 2.0 on the back as well.
It's interesting to note that I saw the FW800 taking a bandwidth hit if the FW400 drives was being read/written to. For example, if I was averaging 50-60MB/sec on the FW800 drives and copy something large to the FW400 drive, each drive averages out to about 30/MB second, roughly half the FW800 speed I was getting. The USB while the slowest didn't cause any slowness on the FW drives.
Here are my Xbench results. These results are from each drive being benchmarked individually with no other drives being tested at the same time.

Computer Suddenly Slow & Won't Recoginze External Hard Drive

Hey All,
My computer has been running really slow for the last few weeks. I can't even open Firefox 2.0 without it crashing. It also won't recognize my external 500GB GTech hard drive at all anymore so I can't listen to music or access a lot of my pics. It's connected via Firewire 800.
I have a 1.54 GHz Power PC G4 and I upgraded the memory to 1.5 GB. The internal hard drive is an 80 gigger with 17G left.
I ran disk utility on the internal and the below is what I got:
Checking volume information.
Volume Header needs minor repair
The volume Homebase needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
* The Repair option is not selectable. What do I do as I don't want to lose anything on my hard drive.
I'd really like to know how to speed my Powerbook back up and what I can do to have it recognize the external hard drive again? And if I should even be messing around with the disc utility?
Any and all help is appreciated.
Thanks!
Powerbook G4 Mac OS X (10.4.8)

In order to repair your internal hard drive, you need to boot from another drive. If you have your OS X DVD's, insert the first one, and reboot holding the C key. From the utilities menu, choose your internal hard drive and the option to repair the disk will be available to you.
Regarding the slow running, you might want to run the Apple hardware test. Insert the OS X DVD, and reboot holding the option key down. Choose the Apple hardware test, and choose the extended test. Does that identify any issues?
If you have OnyX, you might want to run the cleaning and maintenance tabs. In additon, under the utilities tab, run the check on the system preferences. OnyX is available from http://www.titanium.free.fr/pgs2/english/onyx.html

FiOS HD-DVR crashing since adding external eSATA drive

After the recent firmware update, I added an 2TB external eSATA drive to my FiOS DVR. I'd really been looking forward to this because our DVR had been perpetually 90+% full. After a couple of reboots, the drive was recognized and showed as a second DVR at 0% full in the DVR Status menu. Just to make sure everything worked, I scheduled a bunch of recordings to make sure it was utilizing the new drive.
A few days later, we found that the DVR had erased several of our recordings because it was out of space. Checking the DVR status again, the new drive had disappeared.
After a couple of reboots, it appeared in the status menu again, and the DVR started recording to the external drive. But a few days later, my wife couldn't find the recordings. Turns out it had disappeared again.
This pattern has repeated itself several times over the last couple of weeks. On two occasions, the DVR has completely frozen while we were in the middle of watching something, necessitating a complete reboot in order to watch TV, and interrupting any recording that was going on in the background. Each time, at least 2 reboots has been required before the eSATA drive appears.
Needless to say, this whole thing is a disaster. I spent a ton of money and the result is poorer service quality. What can I do to fix this?

After a few minutes searching I found the link of recommended drives.
http://www22.verizon.com/ResidentialHelp/FiOSTV/Other+Hardware/eSATA/129841.htm
Here's a snipet from that page...
Which Verizon FiOS TV DVRs are compatible with eSATA devices?
The following FiOS TV DVRs are compatible with eSATA devices:

Which eSATA external storage devices can I use with my FiOS DVR?
Verizon recommends the eSATA hard drives below for use with FiOS DVR. Customers choosing to install other drive types will assume the risk of compatibility with FiOS DVR and Verizon will not assist with compatibility or performance issues should they arise.

Adding external hard drive to airport extreme for time machine error

Hello,
I recently bought an airport extreme that I wanted to combine with an external hard drive in order to do wireless time machine backups. I hooked this up and the hard drive shows up in the devices menu.
However, when time machine starts to backup, I get the following error:
"The backup disk image “/Volumes/Blackmer External MyBook/Benjamin Crispell Blackmer’s MacBook Pro.sparsebundle” could not be created (error 1)."
When my computer is connected directly to the hard drive, it works fine.
Any ideas on how to fix this?
Thank you.

It is important to understand that Apple does not support Time Machine backups to a drive at the USB port of the AirPort Extreme. So, that may be an issue here.
Despite this, users try it anyway. Some appear to be successful for a time, some partially successful, some can't get it to work at all.
Even if it does appear to work initially, corruption issues may occur down the line without warning. Having tried this myself as a test a few times, I can attest to that.
If you want to try this anyway, the two important things to check are.....
The drive must be formatted in Mac OS Extended (Journaled). Other formats will not work
You almost always need to use a powered USB hub...even if the hard drive has its own power supply....because the USB port is under powered on the AirPort Extreme
You might also want to consider a secondary backup plan to protect your important files

Macpro slowing down cant access FB

Too often people with laptop think this forum is for them, it is for workstation though.,
It is hard to imagine a workstation with 4 or more cores and even a paltry 2GB RAM being slow unless it isn't maintained.
Reading page outs, free space, free memory.....
Of course everyone expects or doesn't know what to include, what they will be asked, so we play 20 questions to figure out why,. And know what? there are literraly 1000+ threads in OS System Software forums of the same nature, over and over with much the same 'tips' and such. And I'd say laptops are most frequent to have slow systems. Mayhbe not always.

Query slow down when added a where clause

I have a procedure that has performance issue, so I copy some of the query and run in the sql plus and try to spot which join cause the problem, but I get a result which I can figuer out why. I have a query which like below:
Select Count(a.ID) From TableA a
-- INNER JOIN other tables
WHERE a.TypeID = 2;
TableA has 140000 records, when the where clause is not added, the count return quite quick, but if I add the where clause, then the query slow down and seems never return so I have to kill my SQL Plus session. TableA has index on TypeID and TypeID is a number type. When TablA has 3000 records, the procedure return very quick, but it slow down and hang there when the TableA contains 140000 records. Any idea why this will slow down the query?
Also, the TypeID is a foreign key to another table (TableAType), so the query above can written as :
Select Count(a.ID) From TableA a
-- INNER JOIN other tables
INNER JOIN TableAType atype ON a.TypeID = atype.ID
WHERE atype.Name = 'typename';
TableAType table is a small table only contains less than 100 records, in this case, would the second query be more efficient to the first query?
Any suggestions are welcome, thanks in advance...

TableA now has 230000 records and 28000 of them has the TypeID 2.
I haven't use the hint yet but thank you for your reply which let me to to run a query to check how many records in TableA has TypeID 2. When I doing this, it seems pretty fast. So I begin with the select count for TableA only and gradually add table to join and seems the query is pretty fast as long as TableA is the fist table to select from.
Before in my query TableA is the second table to join from, there is another table (which is large as well but not as large as TableA) before TableA. So I think this is why it runs slow before. I am not at work yesterday so the query given in my post is based on my roughly memory and I forget to mention another table is joined before TableA, really sorry about that.
I think I learn a lesson here, the largest table need to be in the begining of the select statement...
Thank you very much everyone.

Video slows down after adding text

hello, would appreciate any pointers to solve my problem.....every time i add text to my video project, the video will play very slowly (jerks) until the text ends.
this never happened before as my previous projects ran smoothly even with transitions and text.
anything i can change to fix this? i have not installed any new apps, now notice any slow down of any other application that i use.
thanks.

I also experienced the same problem, regardless of long or short movies... I'm sure you are also experiencing this issue on your preview screens (both small and full screen).
Here's what I did... I just went ahead and exported the movie to media browser and iTunes. I tried playing back on iTunes and it works perfectly. I also tried burning the movie onto DVD and it works perfectly.
Bottomline, just go ahead and export the movie, then burn it onto DVD or whatever your preference is, and you should be fine.
I'm working on another project now, and it's doing the same thing again. But, I'm not really worried anymore because I'm pretty sure it'll be alright once exported.

Adding external hard drive space to eMac - help please??

Hi - I have just purchased a 320gb Seagate external HD as my 80G eMac HD is maxed out with pics, itunes, games etc etc...thanks to my kids!
I must be naive, but thought it would be as simple as "plug and play", but have not been able see the External Hard Drive (EHD) appear in Finder or Desktop, once tied in through firewire or USB ports.
When I follow the instructions available from online support, it's not enough to get a solution.
Can I please get some help....any ideas???
thanks Mac friends

Kieren,
Welcome to the Apple Discussions!
Use the Firewire connection; a USB 2.0 model eMac can in theory use a USB connection, but the drivers for USB hard drives is problematic. The Firewire connection will be both more robust and faster in practice (USB 2.0 is nominally rated faster than Firewire 400, but in real-world thransfers, Firewire wins).
With the external HD connected, open Applications> Utilities> System Profiler and check under the Firewire heading. Does the drive show up at all? Do you have any other Firewire devices attached? If there are other Firewire devices attached, dismount and disconnect them. If no Firewire devices shows up, or more tellingly, if the Firewire bus itself doesn't show up in System Profiler, it's possible that a power glitch may have caused the Firewire bus to latch up. Reset the Firewire bus triple fuses by removing all peripherals other than the keyboard and mouse, then removing the power cord from the side of the eMac (to remove the trickle current drawn by modern electronics even when nominally off) and waiting 15+ minutes. Then reattach the power cord only restart the Mac. Check Apple’s System Profiler (in Applications/ Utilities) and confirm that the Firewire bus is recognized. Reattach peripherals one at a time, checking System Profiler after each to confirm the addition is recognized.
If the external HD still doesn't appear in the Finder, open Applications> Utilities> Disk Utility and see if the drive appears in the leftmost window pane of that program. If it does, you can use Disk Utility to reformat the drive as Mac OS Extended / HFS+
If none of these steps help, I'd wonder if the drive itself is bad and should be exchanged. Check the drive on a different computer.
Once you have the drive avaialbale on your Mac, you can use Disk Utility to partition the drive. I'd suggest making the first partition a little larger than your present internal hard drive; you can then use a third-party utility such as CarbonCopyCloner or SuperDuper! to clone the internal hard drive to the first partition of the external hard drive as a bootable backup. Then if there's a problem with the internal hard drive, you can use Startup Manager to boot from the external drive.
You'll also want to look over:
iTunes: Moving your iTunes Music folder
iPhoto: How to move the iPhoto Library Folder
Try to keep between 1 to 5 GB free space on the internal boot hard drive (depending on whether you burn CD-R or DVD-R discs) to allow for necessary cache and swap files

Slow performance with Seagate External USB Drive

I have a 250GB Seagate external USB. The external drive is not a pocket drive and it has its own power supply. When I first got the drive (a few months ago) I mounted, paritioned and formatted the drive without any problems. I backed up my Mac HD with the included Bounce Back Express software and it took a few hours with around 60GB of data. I also updated the files a few times over the last few months with no problems.
All of the sudden my Powerbook stopped mounting the Seagate drive when I plugged it in. I went into disk utility and ended up reformatting the drive (with Mac OS extended) and then the Powerbook mounted the drives. However, now when I try to backup files to the drive it is extremely slow. It is only transferring files at around 25 MB per minute. It will take well over 24 hours to back up the drive at this rate when it used to take a few hours.
Seagate's website is no help, all they say is that Powerbook G4's have USB 1.1, not USB 2 which is why it is slow. I know this is not true.
Does anyone have any idea why file transfer to the drive is suddenly so slow?
Thanks.

Could you describe the cabling which connects the drive to your Mini, how the drive is powered, and what else is connected via usb to your Mini? Thanks!

Mail Send Speed has slowed down since adding 10.6

I updated on Saturday and now it takes much longer for a message to send. I tested with a small (64K) photo and it took 1.5 minutes to send it. I am no computer expert and need an easy fix.

I am also having this problem and it has been there from 10.6 and 10.6.1. The 10.6.1 update seemed to help - it about halved the delay in sending, but sending still takes a long time - about 30-45 seconds.
Anyone got any ideas how to solve this?
Thanks, Tom

BOOT FROM AN EXTERNAL USB DRIVE???

I know apple has made it clear about booting from an external USB drive
http://docs.info.apple.com/article.html?artnum=106474
but I know that there are people who are able to boot from an external drive, does anybody know how to do this?
It's just that id like to work on final cut studio on an external drive for various reasons:
1st: my powerbook's HD is small and slow (60gb)
2nd: my external usb drive is big (160 gb) and fast (7200 RMPS!)

"Actually, USB II is faster than FW 400."
In theory, probably. In real life Firewire 400 is much faster than USB2, not to speak of Firewire 800:

Slow down when using SHARE function?

Whenever I use the share feature to wirelessly transfer files from my Mac Air to my Macpro everything on my macpro slows down. the mouse moves slow- windows take forever to respond- or just will not close at all. I tried switching my wireless mouse to a wire and same issue. Shouldn't the transfer be a background task? Why is it effecting the overall performance of the machine?

Your explanation makes sense; I had not considered the output size because I thought that the application would make all the necessary adjustments to the size I chose.
I was not able to find the square pixel reference (below is the advanced area) but I did resolve the issue. At first I changed the output to be 400 x 300, and while the bars still existed, they were greatly reduced. So I took a screen capture and in Photoshop measured the height of the remaining top bar at 3 pixels. So, I reduced my height in PrE7 by a total of 6 pixels to 294 and that completely corrected the issue. Thanks for your help on this.
