Hardware :: Extremely Slow Transfer Rate In WD Elements External HD?
Sep 30, 2010
I am trying to use a WD Elements external HD formatted to Mac OS Extended, and the box says that the HD should have a USB 2.0 adapter, meaning it should transfer over 400 MB/s. Unfortunately for me, I've had many problems with this HD and it is now crawling at around 2.5MB/s, slower than 1.1 speeds. At the moment, it is at 750MB/93.51GB - About 21 hours. This is unexceptable, and I make HD videos, which are usually from 200 - 500 MB, and this would take AGES! I had no problems on my PC with this drive. Please help me! Should I format it to something else, get a new one, or something else? Please leave your suggestions below. Also, if you have an HD that works well, please leave it below,
P.S. All ports are free, except for the one with the HD in it. All that I have hooked up to my Late-2009 21.5" iMac is my wireless Apple keyboard, and my Magic Mouse. Nothing else hooked up to the computer AT ALL!

I am wondering why my MBP takes about 7-8 mins to copy 700 mb files from the external (Seagate FreeAgent pro 500 Gb) and of course, it takes about 1 hour to copy 7 Gb files.
However, this problem has occurred only copying file from external to my MBP, the transfer rate is fine when copying files from MBP to external
Note : I've already repair the disk by using disk utilities, but it doesn't help me at all.

I have used the disk for a number of years - all appeared to work fine - I am now backing up my data and only get Very slow transfer speed using firewire 800 - 2 hrs to transfer 1.36 Gb. Disk is connected to a Dual 1.8 Ghz Power PC G5 with firewire 800 - another d2 disk is connected to it with firewire 400 and I have just connected a Maxtor disk using firewire 400 to that. I have tried Updated the firmware (it did require it), tested the device alone on both 800 and 400 connections both slow. Restarted everything and used disk repair to check and repair the disks - repaired permissions on the startup disk.
Connected all the devices together again | LaCie 800 - LaCie 400 - and Maxtor 400. It sends data to all the other devices fast (~ 3 min for 1.6 Gb) through the LaCie 800 disk connection!, but does not send data to the LaCie 800 fast at all. Tested the other devices alone as well - they are all fast. Have also performed a TechTool Pro Ver 4 test on the the disk (Disk type ST325082 3A 232.89 Gb LaCie d2 External LUN0 revision 3.03) Passed the surface scan, disk controller and read write tests. Is the disk failing?

This ended up being pretty long but I tried to include as many details as possible. If any more information is needed please just let me know in this thread. I have been trying to figure this out all day and it has been driving me nuts. First of all I have a Macbook with a 2.4GHz Intel Core 2 Duo processor, 4 GB of RAM and am running Mac OS X Version 10.5.6. Also this is the last generation of the "white" macbook that came out in February I believe of last year.
My external HD is a 1TB Rock Mobile Disk. For some reason when I try to transfer files to or from the external HD to my Mac I am getting nowhere near the expected 480MB/s. I do use a Swiss Gear 4-port USB splitter. When I use the splitter I am getting a transfer rate of about 120MB/s and without it I am only getting about 300MB/s. This is of course if I am only trying to transfer one 800MB movie. If I attempt to transfer multiple seasons of television shows it will drop to as low as 40-50MB/s. Also, if I were to be transferring a single season of a TV show. The transfer speed is much faster to click and drag every episode from my HD to my Mac than it is to transfer the entire folder at once. The whole folder might take 25 minutes but one at a time it will only take about 5.

I did some experimenting this evening to assess data transfer rates to various storage items in my home network which uses a new Time Capsule as the router/hub.
Connected to the Time Capsule are the following:
- Mac Pro (GigE)
- Vista Machine (GigE)
- MBA (Wifi)
- Raptor Drive (USB 2)
- Time Capsule Drive (Internal)
Transferring a 650MB file between devices yielded the following results:
MP > Vista (GigE) = 288 Mbps
MP > MBA (5GHz) = 52 Mbps
MP > MBA (2.4GHz) = 43 Mbps
MP > Raptor (TC USB) = 38 Mbps
MP > TC Drive (Internal) = 38 Mbps
MBA (5GHz) > TC Drive (Internal) = 22 Mbps
It seems that transferring files to a USB drive or the internal drive on the Time Capsule is painfully slow. It took 2:20 to transfer the 650MB file to the Time Capsule over GigE vs. 0:20 seconds to another machine. What's worse, is that the data transfer speeds to the TC are a function of link speed, the slower your connection, the slower your transfer rates. It's not simply limited by some bottle-neck in the TC. It took 3:45 to transfer the same file to the TC from the MacBook Air over the 5GHz WiFi connection. When I complained about this the other day at the Apple store, the "Genius" said that it's due to QOS built into the router to ensure it doesn't kill my web browsing.

So I have a late 2008 MBP and the battery is draining way faster than it should. Coconut battery says that my battery capacity is at 93% and it only has 73 cycles but the battery has only been lasting 3 hours at best with a full charge, but most typically, it only lasts 2 hours while using the 9400m GPU and at idle. I have reset the battery per apple's instructions 2 times now and I have reset the SMC multiple times. this is what the system profiler says about my power capacity and consumption:
Model Information:
Serial Number:6N839TV313EB
Manufacturer:SMP
Device name:bq20z951
Pack Lot Code:0000
PCB Lot Code:0000
Firmware Version:002a
Hardware Revision:000a
Cell Revision:0100
Charge Information:
Charge remaining (mAh):3522

Charging:No
Full charge capacity (mAh):4226
Health Information:
Cycle count:72
Condition:Normal
Battery Installed:Yes
Amperage (mA):-1449
Voltage (mV):11830
This all happened out of nowhere one day, I used to get a solid 5 hours on each charge a month ago and now this.

The hard drive on my iMac is filling to capacity at an extremely accelerated rate. In order to have functionality, I had to delete some unnecessary files and used WhatSize to try and determine the culprit. When backing up my hard drive yesterday, Mail was showing to be 91G. The hard drive filled up again a few minutes later so I copied iTunes to an external drive for safe keeping freeing up 85G.
By this morning that was gone as well so I copied contents of Pictures over to external hard drive freeing up 189G. Mail is now up to 244G on my 500G hard drive. I rebooted at that point to see if that would stop the growth and it has currently, but it may start again. WhatSize says there are no duplicates. I am receiving and sending the same amount of mail that I usually do on a daily basis, so that is not the problem.

My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little.
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!

I just installed Vista on my Mac Pro (2.8 GHz Octo, 4 GB RAM, 8800 GT, 500 GB Caviar SE from WD) and I get 5.9's for everything but "Disk data transfer rate" - which is a 5.7. I know that is nothing to complain about, but I am just wondering what would earn a 5.9? Would it take a raptor to do that? Or just mine is not all that fast or something?

Not sure what I did to cause this, but all of sudden the front side USB ports have reduced transfer rates.
What can cause this issue all of sudden?

I just installed a new Hitachi E7K1000 1GB HD into my Powermac G5. I then found out my Powermac only uses drives at the 1.5GB transfer speed rate... i checked the specs for the hitachi drive at OWC and it says it is 3.0GB, not a 1.5/3.0GB hybrid. Could this cause trouble? The drive seems to be working fine so far... but does this mean this hitachi drive is not compatible with my mac?

I am transferring my iPhoto library to an external hard drive and it is agonizingly slow. Â
I am attempting to make room on our iMac so am moving our 193 GB iPhoto library to our Seagate 2TB external hard drive. The drive is brand new AND is formated properly as Mac OS Extended (Journaled) but the current copy estimate is for it be completed in over 80 hours. I dont beleive the drive is broken as data is continuing to be transferred and not completely hung up. Â
When I transfer other folders/files the process is much much faster. Problem only seems to be with iPhoto library that I have found. Â

I am deciding to buy a TimeCapsule within next week because my Seagate FreeAgent 500 Gb is already full. But I still not sure about its functionality and warranty coverage.1. How about the file transfer rate in wireless mode(802.11n)?2. Can I use the USB port of TimeCapsule with my old Seagate FreeAgent to expand the capacity?3. Is there any way to install a bittorrent software on TimeCapsule? like Asus WL-500W4. Is it fully support Windows XP?5. Can I use it as a repeater? Is this an option provided in Airport utility?6. I have just purchased an AppleCare for my MACBook pro but I am not sure about it coverage.

My 2.4 ghz IMac is showing a transmit rate of only 78 on our wireless network while my Macbook seems to work fine in the same location with a rate of 130. Is there any way to increase the speed or is their something wrong with my airport, should be faster. When selecting the option key and clicking on the aiport symbol it shows the following data.

How can I find out what my transfer rate is for ethernet and wireless. I switched over to Time Capsule and all N network?
Also, how can you tell if you have the gigabyte cable or the regular cat 5 cable?

Has anyone come across any Firewire memory keys? (Similar to the USB Keys we have now days). Firewire has a much higher transfer rate than USB 2.0, so I was wondering if any company made the firewire memory keys. I did a quick google search but didn't come up with anything recent. All the articles I read were from years ago.

I am doing an initial back up for Time Machine. I've got 56Gigs worth of data to back up from my 2Ghz Uni Body MacBook (with 4gig of Ram & running OS 10.5.7). I have a newly purchased Airport Extreme base station to which is connected to a Western Digital 1 Gig External HD. I am getting a transfer rate of about 1 gig per hour. Is it really this slow? I am using a 5Ghz network to reduce interference and they are very close to each other.
I tried connecting the WD drive to the MB. After I switched off Virus Barrier V5 and stopped Spotlight indexing it was quite fast. However there didn't seem a way of tricking this backup to think it was done via Airport Extreme. How could this be done?
It looks like my MB is going to have to be left on and stay at home for the next couple of days!

my Mac's start up is fine, until I get the the window with the bar that says "OS X starting up". This is the *really* slow bit. I am grateful for the fact that my old Power Mac is yet still faster at starting than my PC, but it is a whole lot slower than it should be. When I say "should be", all the Macs at school, or at the apple shop barely show the start up bar window. Ok, granted that they are a great deal newer and faster, but after a clean install of OS X on my machine, that bar was there for a maximum of 5 seconds. Now it usually takes 20-30 seconds.
Right, on to the things I have already tried:
* Cleaning out login items
* Turning off auto login
* Checking all my fonts
* Disabling the unused fonts
* Cleaning cache files and restarting twice
* Unplugging all of my hardware, bar the monitor
Even after trying everything on this list, plus a few hundred restarts, it is still booting up slowly. Does anybody have anymore ideas? Also, if somebody could please let me know where the log for system start up is stored, I will look through it and post it. Also, I should note that I am running OS X 10.4.11 'Tiger'.

I don't really know what is wrong, it's a fresh installation and it's just extremely laggy, liquify is slow as heck, drawing and doing anything is just choppy or buggy. Heck, my MB is more than decent for PS, so I don't know what is going on!
CS4 ran fine with no lag, and CS3 on my old p4 with 512mb ram runs smooth as silk with no lag, even when I use liquify, and even then it's only allowed to use 170mb of it.
I know this is a well known problem and I am not the only one, but I just wanted to know what exactly is the problem if anybody has managed to fix it, and a lot of the menu's and window structures are a bit off/messed up as well, it seems to me that a lot of unneeded yet subtle changes were made, and it's annoying as well.

I was wondering if there was any improvements choosing an Express Card to eSata over using Firewire 800?
This card states a transfer rate on the card up to 300 mbps which is nowhere near the 800 mbps that Fw800 will give?

So i just got my macbook air today, and im loving it. The only problem is that the internet on this thing is SLOW. I have pretty decent internet at home, both my pc and macbook pro (2007) is fine. But on the MBA, a normal website takes minutes before being completely loaded. I just tested all my computers on speedtest.net, and my mbp was able to get 11.86download and 0.84upload, while my MBA get 0.45download and 0.15upload Is anyone else getting this problem?

I just did a clean install of the mac and I'm noticing it is extremely slow at copying files back from an External HDD. It is on USB 2.0 connection, and still going maybe 10MB/minute. This is the speed I'd expect from a 1.0 connection. I've checked the wires, everything is connected. I thought maybe I'd speed it up by using an External DVD drive to copy the 20GB music library back from the DVDs rather than the external -- but the external DVD drive showed the same slow speed. The drive didn't even seem to spin up to read faster (like it normally would, it reads/writes quicker than the slot drive on the imac).
It just ran as slow as possible, with the same slow transfer rate. I've been going for a couple hours or more now, and only have 4GB of 16 copied over. I'm guessing there could be a reason for this that I'm missing. It's a fresh install, all updates installed on this Tiger 10.4.11 OS X. External is formatted HFS+ and the iTunes library does not contain any single file over 4 GB, or even close to 1GB. (just music/library files). There has been no problem with the media before.

I just dropped in a WD Scorpio 7200 320GB drive in my mid-2009 mbp. I successfully cloned my previous drive. It took forever to boot the first time and every subsequent time. It takes hours to install the os fresh after wiping it. Not at all how I expected the swap to go. What do you all think? Swap it out for another because this one is a bad egg?
I have done a guid partition and it is formatted in mac os x extended and journaled.
When i boot from my old drive, now in a usb enclosure, everything is fine. However when I access the new internal drive it hangs and just doesn't play well with it at all.

My '08 mac pro has a pioneer dvr-112D in it and it seems to be extremely slow when ripping DVDs in windows/bootcamp. It will take 30+ minutes to rip a DVD whereas it only takes 9 minutes on my PC. I ran the Nero discspeed benchmark and it says the drive is only reading at ~10X max at the end of the test. The drive should be good for 18X right?
This happens in both XP and windows 7.
I've checked that DMA mode is enabled so it's not an issue of it being in PIO mode.

Yesterday morning during working on the mac, the system started to become extremely slow till the point that even the mouse didn't respond any longer and I only got the spinning ball showing. No webpages opened up any longer and closing the program I was working in (Sibelius 7), took a very long time. Â
I did a system clean with Onyx (for Lion), did a virus and trojan check and followed the advice on the Viruses page in this forum on checking the firewall. It wx After that everything seemed to be OK and the system was fast again. Now after about 1 hour working, again it styartys to show the same symtoms, getting slower and having the spinning ball showing up more ad more.Â

I was recently given a (supposedly) non-functional iBook. I reinstalled Tiger on it, and it did fine through the installation and initial startup. However, everything runs really, really slow. It will work normally for about 5 seconds, and then slow to a crawl. Opening system preferences just took 5 minutes. The beach ball shows up with nearly every click.
Anyone know what this means? Bad ram? Bad HD? It is the 14" 1.42 ghz model with 756 mb ram.
Oh yeah, the reason it was presumed dead was because the previous owner smacked it on something, and the LCD screen is bashed up. The rest of it seems physically fine, but it was subject to some sort of impact.

So when I use internet to connect to my WiFi connection, the speeds are at dial-up levels. My MacBook is almost right next to the router. After plugging ethernet in to it, it's going as fast as DSL should be.. 10-15x faster than it is over wireless. I understand that wired is always a little faster, but the difference shouldn't be this drastic. What should I do?
