The interface in the case would seem to have failed. They are usually not the same standard as those used in a computer.

I have a toshiba 500gb external hard drive and suddenly it has been making a clicking noise and not working as far as reading how can i fix this fast?

You can't. When you hear the clicking noise every time it attempts to read, the sound you hear are the read/write heads striking against the edge of the enclosure. The drive has most likely failed. The only thing you can try is to open up the case and remove the drive and directly connect to your desktop computer. Another thing that sometimes works is to wrap the drive in plastic and place in the freezer for an hour, then connect it. IF it starts working, quickly save what data you can off of it because it will fail again when it warms up. I don't think that usually works with head failure, but give it a try.

Remove Write Protection From 3tb Toshiba Canvio

I was using XP and windows 7 with my Toshiba Canvio 3tb external and all the sudden I got a "write protect" message from XP and a "bit error" message from windows 7. After trying all the things I found online such as diskpart chkdsk, and changing the registry key, I decided to look elsewhere for my problem. None of these things worked at all, so I realized that the problem must be with a boot file of the Toshiba external drive. Since my drive is partitioned using exfat instead of NTFS, I hooked it up to my Mac (10.6.4). I opened up disk utility and selected the Toshiba drive. It would not allow me to repair permissions so I went to "verify and repair" instead. I ran it twice. After the second time I could now write to the disk and delete from the disk. I hooked it back up to my pc and it works fine. I lost no files. I still don't know how it happened, but its fixed for now anyway.

Suddenly, my 500GB Seagate external hard drive couldn't mount on my iMac. It was working fine till yesterday. I connected them to the Mac USD port, and the light in the seagate is blinking... Any

I can only comment generically:

I would try to uninstall the drive on the OS. Then re-start the computer. After the re-start, connect the drive and see if the drive re-installs itself.

If the error persists, then the drive is indicating failure. To absolutely verify if it has failed, take the drive to a store where there are MAC computers and try the drive on one of their computers to see if it works.

A continuous flashing LED on most devices where the LED does not normally continuously flash is an indication of a failure of the device. Some devices will flash an error code when designed to do so, and if possible.

My hard drive is suddenly undetectable by mac. when i plugged it in windows, it said "the drive is not formatted" how do i retrieve my files?


The Mac and the windows file system are different. So if you will connect a Mac file system formatted hard drive to a windows system then it may occur. To retrieve your data from your MAC hard drive you have to connect the drive to a Mac system.

Check the cables of the hard drive or replace them. You can try to connect with another port of the mother board. If the Bios don't detect your hard drive then check the bios settings. If the bios detects your hard drive but you can't access it then try to repair the OS to retrieve your data.

My toshiba calmee titan cannot be read modified with Mac

The hard drive needs to be either a) reformatted with a file system the Mac can manipulate (HFS+ would be ideal) or b) install MacFUSE NTFS-3G.

I cannot copy files FROM my Western Digital 500GB


Check the file system of your hard drive. If your PC is recognizing it, check if its a FAT or NTFS. If it is NTFS then you have to reformat it using your Mac and choose FAT. Mac OS recognizes NTFS as a read only drive. If you plan using it with your PC and MAC you should format it using your mac and choose MS-DOS in disc Utility. You cannot format the drive using your PC Computer with a FAT file system because of the capacity. Only Mac can format it with a FAT file system.

M-Audio Keyboard 49e disfunctions after some time

Sounds like it might be a power supply issue. Unless it is mains powered.

Try removing all other USB devised. If that doesn't work its worth try a Mains Powered USB hub.
