Ext HDD transfer speed

I just bought a WD Mybook 160gig external hard drive with a USB connection yet the speed of the transfer is rediculously slow from the powerbook to the HDD.
ie: It took 4hrs to transfer about 10gigs of music. It also took about 3.5hrs to rip a full length dvd movie(~9gigs) to the external HDD.
From what I gather, it should not take that long to transfer items to an external drive. I was told that it was possible to rip a dvd in less than 30 minutes.
So if anyone would be able to provide me with some help, advice or what not with increasing date transfer speed, I would be greatly appreciative.
thanks in advance

Welcome to Apple Discussions!
First off, the rate of speed you are getting is typical of USB 1.1. USB 2 was not introduced in Macs until June 2003 with the PowerMac G5, and later with the rest of the Mac lineup in September and October 2003.
If you want faster speed move the hard drive out of the USB case and put it in a Firewire hard drive case (if the MyBook isn't one) such as those by Relax Technologies ( http://www.granitedigital.com/ ) or http://www.macsales.com/
If the MyBook has Firewire, use that instead of USB.
PCMCIA to Firewire and PCMCIA to USB 2 adapters also exist, but usually don't supply power to the drive, and are limited to 20 MBps. Better than the 12 Mbps of USB 1.1 which is limited to if no other items are on the USB bus. If other items are on the USB bus, then you will only get the speed of the slowest item on the bus. Use Apple menu -> About This Mac -> More Info to launch the System Profiler and discover what is on the USB bus by selecting USB in the Hardware section of the System Profiler.

USB vs. FW External HDD Transfer Speeds

I recently (yesterday) bought an Iomega minimax 250GB external HDD to go with my imac. I know that this is desined for the mac mini however I liked the USB/FW hub capability and the small footprint.
The main purpose was to clone my 160GB internal HDD and use the remainding space for DV capture and editing.
I have noticed that the transfer rate between the USB2 and FW conections is very different. I am getting approx 13MB/s from the USB2 and 30+ from the FW and was wanting to know why the USB2 was so slow. The HDD is connected directly to the back of the imac and the only other USB2 device conected is the keyboard.
I know the simplest answer is to forget the USB2 connection however to ustalise the USB and FW hub capability I need to have both connected and the system does not seem to allow me to set 1 as priority over the other and the USB2 is the default.
Any suggestions would be greatly appreciated.
Cheers

I was not aware that you could prioritize the usb/fw
connection. I just assumed that fw was the default
when both cables were connected. How do you
prioritive the connections? I am not sure what the
value of a hub is because both usb and fw devices can
be daisy chained. I have a combo ext. HD with a usb
hub but I only use the FW port. Keeping the usb
connection also takes up a port on my IMac.
Sorry been away for a bit. There is an Auto/1394a swith on the back to switch between the Firewire and auto. Has made a significant diff setting to FW over the USB2.0.

Advice pls: V.slow transfer speeds to external FW HDD ... but not always!

I've a WD MyBook Premium 320Gb external drive and I'm getting very poor transfer rates via firewire.
Most of the time I drag and drop multimedia files (mpg or avi) between Finder windows and I get transfers of around 300-350Mb/minute. However on two occasions recently the rate has increased to roughly 1Gb/minute. I can't account for why there is such a huge differential in transfer speeds in the same file type - and neither can Western Digital.
By way of comparison I get roughly 1Gb/m transfer speeds from a USB2 Sandisk flashpen to the iMac, matching the speed increase I've seen on two occasions via firewire.
So I guess the questions that arise are
1. what speeds should I get when transferring large files across firewire? I don't expect the theoretical 400mbps sustained.
2. would speeds be better using USB2?
3. what format should the external drive be and does it make a difference to performance? It's currently HFS+ Journalled though WD say that's not ideal.

I've been digging around a little more and I've found a CNET review of the most popular external drives and Seagate was worst but the MyBook wasn't too fast except for reading whereas the IOMega was the fastest for writing via firewire but not USB.
I think I'm going to have to live with the performance poor though it is for writing. Hopefully the format will improve things a little, if not it's one of the most attractive drive out there so I'll have to appreciate it for its aesthetics.

Is that silly to configure a thunderbolt RAID ext HDD with partitions

I have bought a WD my passport pro 4TB thunderbolt ext HDD. My original idea is to use the two HDDs of the my passport pro (in JBOD ) embodied through thunderbolt and expecting twice the transfer rate from that of usb 3.0 hdd, and 2TB one for storage and another 2TB as time machine.
Disappointingly, it only provide a barely surpass USB 3.0 performance.
Hence, I am considering the following, so as to utilize the Raid 0 setup in order to get a better speed performance.
1) Part the two HDDs into A1A2 and B1B2 (each partition 1TB)
2) Map A1B1 into a raid 0 setup, while A2 left idle and B2 as time machine for the my macbook pro and (A1b1 raid 0 set-up)
3) The speedtest result of A1B1 raid 0 and the indviudal A2, and b2 is apparently ok.
My questions are:
1. Would the setting in this way become unstable? and create silly bugs?
2. I read that Raid 0 demand a whole piece of disk to be used? why I could setup in this way through disk utilities?

BLF call presence is not yet working and I haven't identified the buddy watch or the lines in the config file that address this
You have feature.1.name="presence" feature.1.enabled="1" included in your <PHONE_CONFIG></PHONE_CONFIG> It is "generic enable" for so called "buddy watch" feature. But then, you need to configure who's your buddy.
It is part of phone's directory, e.g. [MAC address]-directory.xml file, but you have no such file. I assume your directory (so buddy list as well) is empty. The file in question looks like
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<directory>
<item_list>
<item>
<ct>110</ct>
<lb>Toby Flenderson</lb>
<bw>1</bw>

</item>
<item>
<ct>106</ct>
<lb>Edna Abbot</lb>
<bw>1</bw>
<sd>2</sd>
</item>
</directory>
The bw is acronym for "buddy watch". Phone directory records with bw=1 are your buddies. It's status is monitored by Polycom phone then.

Why does ext HDD / time machine run slow?

Apologies if this is answered else where, but I can't find any answers.
I have a MBP running OSX 10.6.8. Connected to it as a Time Machine is a Freecom 400GB 28147 uk, external hardrive connected over USB 2.0. I also have a Mac Mini running 10.6.8.
When connected to my MBP, I have found that it is extremely slow to read files. I gave up using it for Time Machine a while ago as I thought there was a problem Time Machine software causing it to run slow. I have also tried to read the time machine backups through finder and they are still slow to read.
Today (don't know why i didn't do it before now) I plugged it in to my Mac Mini with USB 2.0 and found that I can read all the time machine files at lightning speed, far quicker than my MBP which can take 2-3 mins to open a folder. I have noticed that the hard drive doesn't make its usual whurring noise when im trying to open a folder using the MBP, right up until the last minute before the folder opens.
Does any one have any idea about what might be causing the problem when the the ext HDD is connected to my MBP?
Any thoughts or suggestions greatly appreciated.

How are you connected to it? Network problems could explain at least some of what you're seeing.
More often then not I don't know how long the backups take because when it becomes to annoying I stop the backup.
That guarantees that Time Machine will have to do a "deep scan" the next time, comparing everything on your system to the backups. That does take a while, but if there are no other problems shouldn't have a major impact on performance.
All of that said, I can't say for certain that there isn't something else going on. Generally the way I notice the slowdown is when my keyboard inputs come out screwy -- ingB instead of Bring, pplAication for Applicaton for example. When I know that this is happening I can work "around" it by typing the first letter, pausing for a second or two, then typing the remander. Does any of this ring an bells?
I've not heard of that specifically, but if you're connected to the Drobo wirelessly, and using a Bluetooth keyboard, there are reports of interference between the two. Try a wired keyboard temporarily, and/or different WIFI channels.

How to identify damaged files in ext HDD?

Early 2008 iMac - iMac8,1 - Intel Core 2 Duo - OS X 10.6.8 - (int) Samsung SSD 840 EVO 500GB - (ext) OWC Qx2 enclosure w. 4x2TB TOSHIBA DT01ACA200 - Wacom Intuos Pen&Touch tablet (no mouse) - DSL - Flash Player.
I think hardware is the place for this question.
I inherited this iMac back in May/June, spent a month or two with it, did a fresh install of Leopard, and then Snow Leopard on top of that. Everything seemed fine. Speedy response. Decent browsing speed, even with my crappy 3 Mbps DSL.
I added two separate HW upgrades: a SSD int hard drive + RAM to 4GB (installed by reputable local shop), and added a 4-bay ext HDD set up as 4 independent drives, JBOD (purchased from OWC). I feel I made a mistake in doing both of those things at the same time, as I immediately encountered glitches that have been hard to troubleshoot. The worst was the ext HDD / enclosure suddenly un-mounting all by itself, complete with error message ("was not ejected properly"), promptly after which the drives reappear on the desktop, with their contents seemingly in place.
I'm not looking for help troubleshooting; I think I've found the problem, at least for the un-mount issue (bad FW port, thankfully there are two). There might or might not be lingering stall-when-opening-folder issues, too soon to tell. Both vendors have been helpful with their responses.
What I'd like to know is how (or if) the contents of the ext HDDs can be scrutinized for damage? This un-mount thing happened at least a dozen times, and several other times I was forced to manually shut down the HDD enclosure when everything else was frozen. I have to think something's been corrupted or damaged with all of that un-ejected off-and-on activity.
Any input is appreciated. Thanks in advance!

The only meaningful test of whether there are "corrupt files" is to use the computer. If it behaves normally, you can assume that the operating system and applications are intact. As for your other files, open the most important of them and see whether the contents are what you expect.
Though swapping the FW port SEEMS to have stopped the sudden un-mounting (maybe not enough time spent scrutinizing that yet), there is still problematic behavior. Just this evening, after the desktop was on all day but saw little use (Safari, iTunes), I tried simply opening one of the hard drives:
- 8 minutes to simply open the window. Spinning beach ball. Window changed dimensions from prior use, appeared as though it was opened for the first time. It showed no contents.
- 20 more minutes to show contents. During this time, the spinning progress wheel spun. Contents finally showed up.
- 8 more minutes to open one folder. Spinning progress wheel.
Contents appear to be there. This is a storage disc, no backups ever performed. This new 2TB drive contains only 100GB.
This stall seemingly caused other stalls elsewhere. Namely, a simple text copy-and-paste function in TextEdit. When the HDD finally decided to finish, TextEdit was available to me again.

Ext HDD seen by 2011 MBP but not 2014 MBA

Hi all
My GF just unboxed a new 13" MBA. One of the models refreshed last week
She wants to set up fresh & just bring over some data from ext HDD's she used with her old MBP.
It is a 2Tb Seagate Drive (USB 3), which has an external power supply.
The drive is formatted into 2 partitions, a 1.5TB OSX Journaled and a 500Gb FAT-32 (for when she needs to transfer files to/from a PC).
The drive shows up fine on her MBP just fine. In Finder & Disk Utility.
However on the new MBA, there is no signs of it at all. Disk Utility & Finder shows nothing.
Both left & right USB ports on the new MBA work ok. I can see a different Western Digital (USB 2) powered ext. HDD no problems.
The Seagate drive LED lights up when plugged into the MBA and you can hear it spinning, it just won't show anywhere in the OS.
Any ideas brains trust?
I've done all the usual troubleshooting.
Could it be something to do with the firmware on the MBA needing upgrading?
Thanks, Luke

hi
typo mistake, what I meant to say is that your external HD is recognised by you old MBP and it is running in MBA but not shown (not being recognised as external USB) as you said that "The Seagate drive LED lights up when plugged into the MBA and you can hear it spinning, it just won't show anywhere in the OS." , have you checked that the power for the exHD on? because as I said ealier that I have ex HD imation 1 Tb used as backup for TimeMachine and someday forgot to turn on the power supply but when the exHD was plugged, the LED ON and I could hear the drive running, unfortunately not recognised by me MBP until I turned the power on. If the power is ON in your exHD then I suggest to contact apple customer service not the community only as you MBA is 2014 and under warranty

Too slow transfer speed for Toshiba 3.0

Hi there
i just purchased a toshiba 3.0 external hdd.
I use windows 7 genuine.
My pc specs are pretty ok cos i am able to run heavy games like crysis 2.
The problem is, My external hdd has slow transfer rates. This problem i started facing aroung 3 months ago. My hdd is out of warranty.
My USB ports are ok and i connect it to primary port.
The transfer speeds are just around 10MBPS and sometimes it drops to KBPS!!!!
Also, it does not copy some files and gives error "Failed to read from source disk" or something like that.
There is no Virus in it, I have enabled write-cache. I have defragged it.
My OS is fine and also, i checked it on other OSes.
Also, i have tried using "check disk for errors" with proper procedure but it hangs somewhere in the middle after it processes 500000 sectors or so.
I got my HDD from my cousin as he no more used PC and without any cover so i dont have any idea of model (although if there is any utility to find model then please notify me).
Also, it worked fine during then. Me and my cousin are from India only.
How can i fix this issue?
Please help me.

Questionable transfer speed of Zen Stone Plus over

I'm going to make this short and sweet. Ever since I purchased this (4 days ago), every single transfer I've made via the 0cm long usb cable provided with it has been rated rather low.
USB 2.0 has a maximum potential TX speed of 60MBps, however with the miniscule cable I was provided, TX speed is no faster than .MB
ps.
I did my first TX before firmware upgrade and it was rated at .MBps, I then not long ago upgraded the firmware, but no change.
Any reason why this is such?
Btw I'm on Vista Ultimate 64bit, and the firmware version I upgraded to is .03.0
Other than this, It's all fine (except the stopwatch has choppy framing when used and while playing music at the same time, but that's another matter).Message Edited by Capt-Irrelevant on 09-07-200708:52 PM

hi there!
ih have exactly the same problem! (I also have this choppy stopwatch only while listening to a song) I think my Player is a bit slower: for ,3GB i need 40minutes....
I received my player today and searched hours in the web for a solution. I tried different ways of transfering the data, nothing worked. Every other USB2 device (Stick, HDD, Mini HDD...) works perfect!
I have a Kubuntu Li've-Boot CD (u dont have to install this OS it only boots from CD) and while using this OS i have the full transfer-speed in both directions. In Windows XP SP2 i only have the full speed while copying data from the player to my disk.
Well.... i think it's a driver/config issue cause thats the only thing that have change in the Unix system but i cant figure out what exactly cause this problem: i used different ports, changed the energy options in windows, updated chipset driver, reinstalled player, unplugged other devices. i think the players ressources are used by something else or another thing already use something that the player needs.
Tommorow i will test the player on other PCs and Unix systems and with an USB-hub.

plz someone who ever experience or know the solution help me
thank you very much before

Hi,
Have you installed ALL the drivers before you made any tests?
You might also want to Clear the BIOS (Copied from Troubleshooting Guide V1.0 as I couldn't find the link for just clearing the Bios):
Quote
Clearing the CMOS chip
Disconnect the system power cord and push the case power button to drain all remaining power in the psu for approximately 15 seconds
Then move jumper jbat1 and wait 10 seconds and move it back to the original position. You should ensure that the jumper has metal inside of it when removed, sometimes (rarely) they don't. This process resets or clears the CMOS chip and is shown in most motherboard manuals.Now connect the power cord and restart your system.
Some motherboards require that the battery must be removed for 20 minutes before putting the battery and jbat1 back for the CMOS chip to be cleared.

Ethernet intranet transfer speed issue

I followed these directions after suspecting my transfer speed was not what it used to be. I remember when transferring files via ethernet that the speed was quite astounding.
directions:
Network>Built-in Ethernet>Ethernet Tab>Configure drop down>Manually (Advanced), then manually set the Speed to 1000baseT on both, and the Duplex to full, then Apply... sometimes a reboot is needed.
After this resulted in no speed difference, I noticed my cables were regular cat 5, not cat 5e or 6.
So I bought some name brand cat 6 cables.
I am using a gigabit router Dlink dir 655 i believe, with cat 6 cables, but it takes about 1 minute to transfer 1 gig of data between my macbook and my G5 dual 2.3.
I believe this is not optimal speed, it seems i am still stuck on 100mbps.
Help?

External hard drive, error -36, corrupt files and slow transfer speeds

This is a long post but stay with me.
I've got an external 250GB Lacie drive connected to my 24" Intel iMac via Firewire 800. I have approximately 80GB worth of files (including my iPhoto library) on the Lacie that I'm trying to move over to my iMac but have run into some frustrating problems.
Overall, transfer speeds are erratic – fine at times and SUPER SLOW (5 minutes to transfer a 3MB file) at other times. At first I was transferring entire folders, but after always getting errors (error -36 to be exact), I was having to transfer individual files. This works fine as long as the files aren't too big (which makes the transfer speeds SUPER SLOW) and not corrupt (which gets me an error -36). Is my Lacie crashing on me? Is there any hope?
Here's what I've done to try and salvage my sanity with no resolve to my problems (not exactly in this order):
1) Ran Disk Utility to repair Lacie. Everything came back OK
2) Ran Disk Warrior on Lacie. Found a handful of bad items that Disk Warrior was able to repair. Had Disk Warrior replace the old directory of the Lacie with the new directory.
3) Ran Drive Genius: Raired and Rebuilt the directory, did an Integrity Check (came back OK), attempted to Defrag but could not because of errors to the drive, did a Scan for bad blocks (which after running for 3 days! it was only 20% complete and had found over 150 bad blocks, at which point I quit to try something else)
4) Checked that my Firewire cable was properly connected and replaced the older one I was using with a brand new one.
5) Disconnected all peripherals except for keyboard, mouse and Lacie.
6) And at times, even viewing a file on the Lacie has caused my Finder to crash, requiring a restart of my iMac.
I'm sure I've left something off I've tried but you get the idea.
I've read that maybe I can transfer my files using Terminal. Yes/No? Does this bypass any corruption the files may have?
What about creating a second partition on the Lacie and moving files over to the second partition? Does this solve anything? I don't know anything about partitioning so maybe I'm talking crazy.
I've also read that iPhoto tends to corrupt files which makes me hate iPhoto, and myself for not backing up.
And I've read a lot about error -36's and none of it sounds good so I'm just hoping that someone might have other suggestions for me to try and save my files (especially my iPhoto files which include baby pictures that if I lose, my wife will kill me).
So if anyone has any ideas, let me know. Please. I'll try anything.

Hi Aaron Thompson-
I am fairly certain you have a bad power supply brick to the LaCie drive. This is a hard problem to troubleshoot as generally when the bricks go bad they do so slowly and the drive appears to power up and stuff but it just doesn't work.
If the drive is under warranty LaCie will replace the brick at no charge. Otherwise they sell them for around $20US on their website.

Problems with Photoshop performance and data transfer speed on iMac

Two months ago, I started noticing slow performances using Photoshop (above all using clone stamp tool) on my 27" iMac (late 2012). I did the AHT and I found that 8GB of 32GB RAM were broken.
I removed them but the problem didn't disappered, I also noticed that data transfer speed (both copy and paste from/to internal HD and from CF card/external HD) was really slow.
I tried many solutions suggested by Apple support, none of them worked out. At the end, I tried uninstalling and re-installing Photoshop: no more problems!!!
10 days ago, I received a new 8GB RAM module and so I installed it back... suddenly, the problem came back, I tried re-installing again Photoshop but the problem, this time, still persist!
Does anyone had the same experience? All other CC programs work well (LR, AE, Premiere...)

yes, it does!
what seems to be very strange to me is how data trasnfer speed could be affected!
(just to say, I've already tried reset of SMC and PRAM, I've tried with different accounts and I've also re-installed the OS, next step would be formatting the disk and installing the OS from zero)

Airport Extreme freezing when accessing ext HDD

My Airport Extreme keeps dropping the connections when I try to access files on the WD 3TB external HDD connected in the USB port.
I am able to connect to the internet at all times using either a newly purchased 2012 Mackbook Pro, iPad, iPhone or Windows 7 laptop. But when I try to access my files on the ext HDD, it works 1/10 of the time. I am able to access the drive and partitions, but when I select files, mostly movies (avi & mp4), it will more often then none freeze up and drop the network/internet connection. It will then indicate in the Airport utility that the Airport Extreme is no longer in range and there is no more internet until I disconnect the power from the Airport Extreme, wait a few seconds and reconnect the power. 3 minutes later the Airport Extreme is back on-line and Internet and network are restored. I have had to do this more then 8 times this morning alone.
The Airport Extreme is currently using firmware 7.6.1.
Saw many posts dating back to 2008 and have tried changing configs to recommendations, but nothing is working.
Not sure what to do to correct this, need help.

Lebruny,
Did you happen to find the cause of the freez up of you AE?.
I have mine connected to a WD 2TB, and when I heavily access the drive, I encounter the same problem you described.
Thanks,

Very slow network directory listing - but fast data transfer speed once listed?

Hello,
I have really tried to sort this myself before opening up to the community, however I have run out of ideas, and hope someone can offer the magic solution I have missed.
I am currently using the 3.4ghz i7 iMac on a 1GB LAN, running OSX10.7.2 - connecting to a Windows Server 2008 (Running Release 2) over ethernet.
If i go to a network directory that i haven't recently accessed it can take up to 60 seconds to show the contents of that directory. Once i have accessed that folder, if i come out of it and go back in it will be instant again - but the first time it lists the directory it looks like i have opened an empty folder - which after anything from 10seconds to 1 minute will suddenly show the files that are there.
Internet connectivity is fast through the network, and file transfers across the LAN are fast. (showing as approx 300mb per second) I can play and edit HD content across the network with no slowdown so I am confident that this issue is not related to the network speed itself, and is more to do with a setting on this mac.
Symptoms are very similar to this post: https://discussions.apple.com/message/12245148?messageID=12245148&amp%3b#1224514 8 - however i understand that in OSX Lion - SMB was removed - so i cannot find this file to edit.
I have tried bypassing additional hubs in the network by wiring direct cables to the switch that is connected to the file server, this made no difference.
I have also tried disconnecting the ethernet cable, and running over wifi. This fixes the listing problem, but when editing HD content over a network drive, this connection is not fast enough to carry the data without interruption (some projects are linked to up to 900gb of hd video content!)
Using ethernet, I have tried DHCP, DHCP with manual address, and manual mode. All reproduce this problem. i have tried using the windows workgroup, and tried without it.
I have also followed this suggestion: https://discussions.apple.com/thread/2134936?threadID=2134936&tstart=45 and used OpenDNS. this did not fix the issue.
For argument sake, I have also just tested a Macbook Pro running Snow Leopard to see if it was OS related. This reproduces the exact same problem, near instant directory listing on the wifi, a long and arduous wait on ethernet.
I cannot work out why directory listing is instant over wifi, but not over ethernet on 2 different macs, running 2 different versions of OSX. I also do not understand why if the network is having trouble listing the directories - the data transfer speed is 300mbps when i copy files across the wired network from the file server to the mac.
Does anyone have any other ideas as to what could be the problem here? We are about to start work on a very large project, where the content we are editing is spread out across around 200 different network folders (different shoots captured over the past 2 years). We really don't have the time to wait 60 seconds each time we need to access one of those directories to look for a file, and I am very close to pulling all my hair out!
I really look forward to hearing from anyone who can offer any insight.

If you are suspecting that the Windows update had something to do with your LAN going slow, then try the following:
1. Look for updates for your clients LAN NIC driver; or
2. Un-install the updates.
