I have the WD tera byte hard drive and I plugged it in after many months and it will not show that it is working?? Also, a lock is showing up above the one bright light on the hard drive...any advice?

schmuck, under my computer, what does that hdd show?

Very comm in with wd drives. You need repair the firm ware and it may start working for about 10-15 days.The fw repair has to be done by a data recovery expert.

If you have a 32bit system, it is expected to have miscalculations, a 32 bits can only go up to 4Gb for calculations (that is, 2^32 = 4'294'967'296 bytes) a 64bit system can make calculations to 2^64 bytes this is also why you couldn't copy a file larger than 4Gb in a 32bit operating system...
So, if you are running a 32bit OS, you should expect a discrepancy for the total space of the Hard Drive and the amount it shows (that's the 93Gb you are missing as total capacity).
Another reason why it can show you incorrect calculations are damaged sectors on the hard drive it-self. These will present themselves either as occupied memory or missing memory.
So, you should expect some miss calculations and you can expect some damaged sectors on the hard disk (a external drive spins on and off too often, eventually damaging sectors... its a problem of physical drives).
In the end, your disk might be fragmented, so run a disk analysis and a defragmentation on the disk so it can recalculate.
A note: A disk is like a shelve, you put things where there is space, if you remove things, that space will be open, and if you want to put something there it has to be the exact size or small enough to fit there. This effect, when things are small enough leaves blank spaces unusable, consuming space on the hard drive and making the access of files slower, this is fragmentation. In order to expand your disk life expectancy you should run defragmentations...
To run a defragmentation, go to START, write "Disk Defragmenter", choose your disk and run and analysis and defragmentation.

4 GB pen drive show property as 0 byte used and 0 byte free..when subjected to open show insert disk please help!

WD has had issue with eir enclosures if you fixed the partition there is the possibilityt that you lost information in the process.

On thisng that you can do is remove the drive from the current WD enclosure and buy an new one. Then try to see if youa re able to locate any of your files. Also check to see if it reports any available space if it still does not then the actual hard drive hase the issue and you will need to buy a new one.

plug your drive in to your computer, right click
on my computer and bring up disk manager,
open disk manager and see if your wd drive
shows up. then reinitialize the drive and this
will hopefully solve your problem.

Hi, Take the drive to a pc store and ask the techs to move the HDD into a new shell and test it for you. Most likely it's ok and you can just buy a new shell/enclosure for it. If that doesn't work it may need the help of a recovery pro. If that's the case comment back here with your country/state/city and I'll pass on a recommendation for a nearby facility that can assist you in retrieving the files. Chris

Hi...ok lets try this..go and click the Control Panel then find and click the Administrative Tools then (double Click) find Computer Management(double click) and find the Disk Management then (once) then find what HDDrive you need..Thanks and GOD Bless..^_^

hi...if you want to see again the files on the external hard drive i suggest you make to re-install the windows or repairs the windows you`re using or try to update the mother board drivers..thank you...^_^
