T41 not recognised USB Western Digital Passport 2.5" Ext HDD

My T41 used to worked fine with my WD 2.5" ext HDD. For the past 3 months, do not know what happen every time i plug my ext HDD it just not recognised. When i plug this ext HDD to other computers, it just work absolutely fine.
Can anybody help, please.

I had same issue with same type of pc and USB Western Digital Passport. Problems was on laptop usb ports that had gone broken. Laptop didnt have warraty anymore so i had to connect USB-DISK to docking stations usb port that is still working.
Other solution is to buy usb2 PCMCIA adapter.
Mouse worked on laptop port but no harddrive so i think its was some power issue that laptop usb cannot give enoght power to run harddrive.

Western Digital Passport not mounting

I have a western digital passport that I have used a couple of times. Today I was transferring my music and it said there were corrupted files in my music, and all of a sudden the drive will not be recognized anymore. I don't know what to do? I have been reading everything online. I have tried checking disk utility and it does not appear. Tried checking the hard drive on another computer and it didn't pop up. Please all suggestions are helpful.

The Western Digital Passport drives have a reputation for being power hogs. Your Macbook USB port might not be providing enough power to run the drive. This especially might be the case if you are running off of the battery only. Your PC ports might be giving slightly more power that is enough to run the drive.
I have a portable Simpletech drive (120Gb) that actually comes with a Y cable that plugs into two USB ports on my Macbook. This provides enough power to run the drive without needing a separate power adapter. The Western Digitals typically don't come with this Y cable, but one is offered. You can buy one off their website for about $20 that should allow you to use the drive with your Laptop. It's lame that everyone else provides such a cable for free while WD charges, but that's the way it is.
good luck with getting it to work.

Portege R700-17Z bios not recognising USB devices

Hi,
I'm after some advice about a problem I'm having with my R700, I can't get the laptop to recognise USB hard drives at the boot stage. I'm trying to use Acronis to create an image as I have 40 of these laptops.
The USB CD rom drive is recognised, and so is a Corsair USB pen (which unfortunately isn't big enough), but I have three USB hard drives (a Freecom Tough Drive, Buffalo MiniStation and a Western Digital Passport) and none of them are recognised by the BIOS. USB legacy emulation is enabled.
Am I missing something?
Thanks, Karen

In the past many people have noticed the same problem. External HDD cannot be used as bootable device. Paolo is right, you can use USB stick, USB optical disc drives or old USB floppy disc drives.
In my opinion you should create recovery DVD using Acronis and use this disc for OS installation.

Western Digital Passport 250Gb external drive and MacBook Pro

Hello,
Has anyone with the 15" 2.2ghz 120Gb hd MacBook Pro able to connect this Western Digital Passport 250 GB external drive to only 1 USB port and has it working?
I intend to buy both of these hardwares, but was told that I may need to get the extra Y-cable that can connect to 2 USB ports of the MacBook Pro since only 1 USB port may not have enough power to work the WD external drive? The WD drive comes with only 1 "standard" USB cable.
Thanks.

I've got the 120GB passport and it's worked when I plugged it into the right-side port. But I prefer my connections on the left (to keep room for my mouse) so I got a powered Kensington Dome hub that I run thru my left USB port and have plugged the HD into the hub and that also works.

Western Digital Passport 320 GB on macbook

Does anyone have any experience in using a Western Digital Passport _320 GB_ model as an external HD with an intel macbook?
Do you power it with 1 or both usb ports?
Had any problems with it?
Would you recommend?
Thanks, .B.

I have the 160 GB model, and it works fine. I only use 1 port to plug it in. I have two partitions- one for data, and one for Time Machine.

Western Digital Passport and itunes.

I recently got a Western Digital Passport external hard drive in order to put my itunes music onto it, so it would not take up so much space on my macbook. I found it relatively easy to move all my files the first time, but then as soon as I downloaded something from the itunes store, it put it onto my computer. Since the artist was the same as some music I already had, it did not recognize that I did not already have it, so I could not simply move the new music onto the Passport.
I was wondering if there was some kind of sync feature for the Passport to macs, because I know there is for windows. All I want is for my music to continually go to my Passport, and not take up space on my laptop.
Thanks!

If the WD drive isn't plugged in, iTunes doesn't know where your library is, and hence can't properly add the new music files where they should go. The passport MUST be plugged in to the mac before you start iTunes or a new library will be created and your new music files will go in to THAT library.
The simple way to correct this is to take the files you added that did not go where you wanted them and put them on your desktop from the folder they are residing in (if you're not sure where they are, just click 'Get Info' on the tracks in iTunes and it will tell you where the real files are). From there, close iTunes and plug in your WD drive.
Reopen iTunes now and make sure in your preferences that the music folder on the WD drive is selected as your music library location. Then make sure 'Copy files to iTunes Music Folder' is checked. Now drag your music files on your desktop in to the iTunes window. iTunes will then copy those files over to the WD drive music folder and add them to the iTunes database.

My macbook will not recognise USB devices, Help!

My macbook pro with OS Yosemite will not recognise USB devices such as tom toms, digital voice recorders or cameras. I find this frustrating as I can not update or download to my macbook. Any ideas on what I can do?

Have you checked the settings in FINDER PREFERENCES?
Have you checked with the respective vendors to determine compatibility with your MBP?
Ciao.

Latest Initrd not recognising USB storage devices?

Just installed 2.6.30 with all the necessary files. Everything seemed fine, except for one thing: my external USB hard drive is no longer recognised on boot. Here is my fstab and my mkinitcpio.conf.
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>

UUID=da9e741f-3525-47c6-8c7f-edf1ded00e7a swap swap defaults 0 0
As you can see from this, I originally had my external usb drive mounted on /iomega @ boot. However, since that no longer works, I have changed it to /media/iomega and let HAL mount it automatically when I fire up GNOME (the same way I have my flash drive set up). I used the original line with 2.6.29 with no problems.
The strange thing is, the device is there, because, when it fails, I go into single user mode, remount / read-write and then run mount -a and the device appears with no errors. If I change the line so it doesn't do an fsck on boot, it doesn't mount the device, but I do get an error saying the device is not there. I can then mount it manually at the command prompt.
The device is shown in /etc/blkid.tab and in /dev/disk/by-uuid.
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES="piix ide_disk reiserfs"
MODULES=""
# BINARIES
# This setting includes, into the CPIO image, and additional
# binaries a given user may wish. This is run first, so may
# be used to override the actual binaries used in a given hook.
# (Existing files are NOT overwritten is already added)
# BINARIES are dependancy parsed, so you may safely ignore libraries
BINARIES=""
# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in anyway. This is useful for config files.
# Some users may wish to include modprobe.conf for custom module options,
# like so:
# FILES="/etc/modprobe.conf"
FILES=""
# HOOKS
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'modload' may be used in place of 'udev', but is not recommended
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
# This setup specifies all modules in the MODULES setting above.
# No raid, lvm2, or encrypted root is needed.
# HOOKS="base"
# This setup will autodetect all modules for your system and should
# work as a sane default
# HOOKS="base udev autodetect pata scsi sata filesystems"
# This is identical to the above, except the old ide subsystem is
# used for IDE devices instead of the new pata subsystem.
# HOOKS="base udev autodetect ide scsi sata filesystems"
# This setup will generate a 'full' image which supports most systems.
# No autodetection is done.
# HOOKS="base udev pata scsi sata usb filesystems"
# This setup assembles an pata raid array with an encrypted root FS.
# Note: See 'mkinitcpio -H raid' for more information on raid devices.
# HOOKS="base udev pata raid encrypt filesystems"
# This setup loads an lvm2 volume group on a usb device.
# HOOKS="base udev usb lvm2 filesystems"
HOOKS="base udev autodetect pata scsi sata usb keymap filesystems"
# COMPRESSION
# Use this to compress the initramfs image. With kernels earlier than
# 2.6.30, only gzip is supported, which is also the default. Newer kernels
# support gzip, bzip2 and lzma.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
This is essentially the same as I had it in 2.6.29. I did initially use LZMA, since that gives slightly faster compression & decompression, but changed it back in case it was a timing issue (and rebuilt initrd). No joy. I also tried usbdelay=10 on boot, but again no difference.
This isn't exactly a "show-stopper", since the device functions normally otherwise and everything else is fine, but it is annoying. I would much rather have this device available automatically on boot, so that it gets checked when the max mount count comes up.

This was the bug update I received today:
FS#15282 - [mkinitcpio] Latest initrd not recognising usb storage devices?
User who did this - Thomas Bächler (brain0)
You can never rely on external hard drives to show up "in time".
The difference was that adding the "usb" hook to mkinitcpio used to add a 6 second delay on boot by default, this doesn't happen anymore. I think external drives simply don't belong in fstab, because there's too many possible race conditions. If you insist, you can try to force the usb storage driver to scan for devices sooner after detection, see the delay_use parameter to the usb-storage module.
You're going to have to modify the delay_use parameter to get it to work. Be prepared for race conditions, though. I didn't bother myself as it wasn't a show stopper for me, so I've advised that it can be closed as a non-bug.
ETA: usbdelay=10 doesn't work as that flag is apparently no longer recognised for some reason.
ETTA: I've always used UUID in the fstab because udev can remap devices on boot (I've had fstab not recognising devices because of this).
In case some people don't know, to see what the uuid for a device is, use the following:
sudo tune2fs -l <device-name>

Win7 connection driver instaled OK.
I see the HD in the "Printer and device" menu.
With Win7 Explorer i cant find it.
Have a suggestion?
Tank you.

Hello, what Format is the external drive?
Does OSX see the drive fine?

IMac G5 with OSX 10.5.8 does not recognize my Western Digital external drive containing the majority of my music library. Is there any way to access that drive and recover the music stored there?

I have an iMac G5 with OSX 10.5.8 that does not recognize my Western Digital external drive. I had no problems with this until I upgraded to 10.5. Most of my music library is stored on the external drive. Is there any way to access it to recover the music?

How is it connected? Have you tried different port? How about logging in as a different user then trying to mount the drive.

Mid 2009 macbook pro 13" not booting from Western digital hard drive

So i've gone ahead and purchased a Western digital 2.5 inch scorpio black 750gb 7200rpm sata 16mb internal hard drive to replace my critical status 160gb standard drive in my macbook.
I have followed a guide using a usb 2.0 enclosure, with my new hard drive then carbon cloner which does allow me to clone a copy of the existing hard drive, but... when i boot up the macbook holding the option key i get the external hard drive which i can select but then i go into a os x utilities screen and does not boot straight to finder.
I get four options and one of them is disc utilities, so assuming this process in't as straightforward as i'm led to believe?
I have partitioned the new hard drive with guid for intel macs so pleae can anyone help me before i just give up and take it to my local apple store?
Thanks matt.

I have just solved this problem, with a fresh head this morning i realised that the external drive was empty and the cloning process didn't complete for some reason?
Anyhow i ran the clone again and booted externally which worked so then replaced my old hard drive with the new scorpio black and wow what a difference! I had beachballing before as my old drive was critical but now with the with the new speed 7200rpm drive its flying, very happy:-)

External FW/USB Western Digital, Seagate Disk Drives and 'Sleep' function

As you are aware, most external disk drives be they FW or USB (and irrespective of the manufacturer, save for LaCie) have a 'sleep' function built into their Firmware. In the case of the Western Digital and Seagate Ext FW drives I have, this function cannot be disabled and this per both WD and Seagate.
Unfortunately this is extremely annoying if using Photoshop and Bridge...it takes about ten seconds for each disk to spin up while the latter programs search the drives. (In Windows this can be enabled/disabled. Not so with the Mac O/S I have been told). Multiply this by six of the aforementioned drives and it can be quite time consuming.
Is there an OS-X workaround for this?
Thanks again,
Lyman

I always avoid vendor cases. Might want to look at an Oxford 912 etc, or better yet, why use Firewire when eSATA works so well?

Remotely access usb western digital 2tb storage connected to airport

Hi everyone, just wanted get some feedback on this set up, if it is possible, and how to configure the settings properly. I want my Netgear n600 router Version 1 + Airport Express + WD 2tb hard drive to = a personal cloud that I can remotely access. I have a netgear n600 WNDR3400 that has a 2.4ghz and a 5.0ghz wifi network capability. I 30-30-30 flashed the netgear n600 router so that I have dd-wrt firmware( DD-WRT v24-sp2 (12/08/11) mega) running on the router instead of the restrictive built-in netgear web interface. I have an Airport Express 802.11g version 6.3 that I have connected to the netgear n600 router via ethernet cable. Connected to the airport express, via usb 2.0, is a Western Digital 2tb hard drive (externally powered). When I am booted up from the internal macbook pro hard drive mac side (I also have Bootcamp Windows 7 installed that I can boot from) my mac's time machine application starts backing up to the WD hard drive when I connect the usb hard drive to my macbook pro. The entire WD hard drive is formatted as HFS+, however I am considering partitioning the WD at least 3 ways, 1250 gigs HFS+ for mac storage, 500 gigs NFTS for windows storage, 250 gigs for unux / linux storage to host my website. I want to remotely access the WD storage space connected to the Airport Express, specifically, each individual hard drive partition based upon what remote system I am using and the respective partition storage format. If I am on a windows computer, I want to have a 500 gig "cloud" that I can access any computer via a windows Start -> Run or map the network drive. I want the same home server ability as a 1250 gig cloud that any mac can access. I want to have remote read or write priviledges when I connect to this server through the mac finder. Similarly, I want to connect through a linux terminal to have access to my 250gig partition for unix. One last thing, I want to host my website on the WD plugged into my Airport Express. Does anyone have any suggestions what dd-wrt settings I need to change to make this work? I do not understand port forwarding very well at all. I think I understand that I need to have a static ip address and then forward the ports. I just do not know what to set my static ip to, or what settings I need to change in the dd-wrt web interface for forwarding ports. Can anyone please tell me which ports do I forward to remotely access my usb storage and personal website? Any help would be greatly appreciated!
Much obliged, Keento

The Express doesn't support HDDs.

Files not deleting on Western Digital My Book Mac

Hello,
I recently deleted some time machine backups on my western digital my book mac. Unfortunately these files was not been deleted from the drive (the remaining disk space has not gone up circa 300GB). I have looked online and the issues seems to be the afp connection rather than using the smb connection.
I have reconnected using this type, but I am still unable to see the files to delete. I have tried to connect using terminal, but to be honest I have no idea what I am doing. The file path is smb://WubberTimeCapsule.smb.tcp.local/My%20Book...
Has anybody else seem this problem also, does anybody know of a way of deleting these files?

Thanks, it is an external hdd (Western Digital My Book Mac) connected to my old time machine (too small to fit everything on way) via the usb cable. The time machine is connected wirelessly to my network. Unfortunately I can not see the sparse bundle files anymore.
Just for the sake of clarification, that's a +Time Capsule,+ Apple hardware combining a wireless router and hard drive. +Time Machine+ is the Apple software that does backups, to various destinations, including +Time Capsules.+
This originated because I originally created the time machine backup with the external hdd connected directly to the mac. When I transferred the disk to the old time machine, it did not reuse the previous backup but created a new one. Hence in my ignorance I deleted the old files.
Ah, yes, that's a different critter. Time Machine stores backups differently when they're done directly vs. over a network. The backups done directly were stored in a Backups.backupdb folder at the top level of the drive; the ones done over your network have that folder placed inside an odd container called a +sparse bundle.+ You cannot switch back and forth.
Which ones did you delete, and how?
It sounds like you deleted the Backups.backupdb folder, and didn't empty the trash, so they're still in the (hidden) trash folder on that drive. If so, disconnect it from your TC via +Airport Utility > Disks,+ connect it to your Mac, and empty the trash. That will take a very long time, as there are at least a few hundred thousand files there, perhaps many more.
A quick alternative would be to simply erase the drive, via Disk Utility, while it's connected to your Mac. That will erase all the new and old backups. If you just started the new set, that might be easiest.
If you decide to do that, see the green box in #Q2 of [Using Time Machine with a Time Capsule|http://web.me.com/pondini/TimeMachine/TimeCapsule.html] (or use the link in *User Tips* at the top of the +Time Capsule+ forum), for a way to speed up the first full backup.

1.8Ghz G5 (late 2004) can not recognise my sony digital camera

My PowerMac G5(Mac OS X 10.3.9) can not recognise sony digital camera,but my friend have same model G5 with no problem,what shell I do?

Did you use the very same camera on either Mac or just the same model? When my Mac (also G5 1.8 Dual, though the earlier spring model) had problems recognizing my Sony, it was a question of setting the USB mode on the camera: E.G. my camera allow to set its USB mode to either Normal or PTP, the PTP setting caused problems at times, though its too long to tell, of which nature they were. May be woth a try
