My suggestion is to dban the drive, it will take a while, dban stands for darin's boot and nuke, and has the ability to write the drive to all 0's. be very careful with this program however because if you run it on your pc it will erase all hard drives attached to it. so i would recommend swapping the 2.5 out with one in a laptop and running it. if you don't want to go this route, you can also try and use any of a number of free partitioning tools, to format it at a lower level. just search google for freeware partitioning tools. that should fix it.

Deleted partition on asus eee pc900

If you set the bios to boot from USB. Place your USB Bootable stick into the USB socket and boot from it.
Windows will find the hdd and format it before putting Windows on it.
What has happened is the hdd name is missing from the system and it requires initializing before you can see it.

I am unable to install win Xp. when trying to boot from a cd to install fresh win xp ser. 2. system reboot after copying few installation files. The Bios set up shows the Sata Hard Drive but unable to load...

your HDD may be bad. I have had a number of HDD that appear fine in the BIOS but won't format either via the install disk or separately via a Linux boot disc.(You can somtimes hear them clicking on and off [seeking])

If you are mad keen on the drive, then D/L 'Hirens Boot Disc' and boot into the DOS mode (it also has a Mini XP mode).and use the HDD format utlity 'killdisk'. This will remove anything on the drive, format it and set it up ready for a fresh install.

If Hirens Boot Disk can't see the SATA drive then its stuffed.. for sure..

My lacie (1TB - HI-SPEED USB 2.0)is not responding to opening(is not accesible)

Check to see if the HDD appears in the Disk Mgr (you are in Windows(!)) Click Start, Control Panel, Administrative Tools, Disk Manager and see if it appears in the right side screen there? If it does, you might need to write a signature to it so WIN can use it, Partition it so your computer can see it (Not all PC can 'talk' to HDD that big (BIOS thing) and you may only be able to use a logical part of the physical whole 1Tb HDD) Rt click the drive and see what is offered. If the tiny drive Icon is RED or Yellow - there is a problem... and you will need to sort this first. Example: the WHOLE 1TB is 1 partition, but your BIOS can only 'see' a maximum of 500, then it will not be 'able' electrically to 'talk' to the HDD, so it will never go 'ready'. Like a foreigner ;-) Until you get on the right level//terms of communication, it'll never fly. In that case, you MUST either upgrade your motherboard BIOS to handle really large HDD, or delete the 1TB single partition, and make 2 or 3 smaller ones. After you format these, you'll have 2-3 (or more) 'logical' drives within that single 1Tb 'Physical' drive. IF your BIOS can talk to the 1TB size drive, and everything in there is OK, check to make sure it is marked "Healthy(Active)' if not, Rt Click and format it. If you need to format, I strongly suggest you use QUUICK/FAST method, or you will be there all night waiting for it to finish. If all this has been done, the Partition is OK, formatted and has been labelled Healthy(Active), make sure that it has a driveletter assigned ;-) Just Right-click inside the drive BOX and select 'Change Drive Letter and Paths. This is not always done automatically and no driveletter can be a BAD thing. OK.. If it is Partitioned, Formatted, Healthy/Active and has a letter and you STILL cannot see it when On and plugged in... carefully put it to your ear - or your EAR to IT ;-) and Now flip the power switch ON.
Does it spin up, make clickety-clicking sounds and then get quiet? That my friend is HDD POST and Head0 track0 sector0 seek. It will try this 3-10x and then turn itself off - BAD HDD TAKE IT BACK!! If it keeps running, After all that POST stuff, the drive should be quiet for some 2-3 seconds and then make alot of noise. Some Ext USB drives MUST be connected to the host (PC/Laptop/MAC) in order to power on. If yours doesn't make any noise (except maybe the internal fan) turn it off and plug the USB cable to a different USB port (could be the one you are trying is dead) and retry the above. Immediately after it quiets, you will hear a loud click and then alot of noises as it reads off the files, scanning the HDD. This is always accompanied by alot of flashing of the read and write activity lights on the HDD. If still dead, get another USB cable and try that (there are alot of bad cables out there) I am assuming that the USB ports you are trying *used* to work? If they are on a new card or PCMCIA adapter, install that first, THEN reboot, THEN try the Ext HDD. Latly, if you ARE getting all the noises, lights and such, and still cannot see/read the drive, it may be jumpered incorrectly (Did you put it in the case?) Otherwise - Don't open the case, take it back and get a replacement.
Good Luck!

Windows XP stopped recongizing eGo external Hard Drive I just installed a new iomega eGo 1 TB desktop Hard Drive yesterday, got the bugs worked out and my Dell w Windows Xp seemed to recognize it, Today,...

2 things... the USB port is bad, or the USB cable is too long and the HDD isn't getting a good signal.

1. Try another port and see if that works

2. Nip over to WalMart, Circuit City, Micro Center, PC World or Best Buy and get a shorter, Thicker USB cable of the same type - a cable which can provide the signal strength your ext HDD requires.

Also a possibility... The HDD may be 'lost' as Win cannot accept one of that size or the label/signature fell off and it is an orphan. It MUST have a driveletter, and it MUST have a special WIN signature byte on the HDD for it to work.

Bootup as normal, let everything get quiet, then plug in the ext HDD

Rt Click My Computer, Manage, Device Manager and in the Rt side, highlight the TOP icon. Then under Help, click the Computer with magnifying glass icon and wait. This forces your OS to 'Look' for any new devices.

When it finishes looking, look again under My Computer to see if your new HDD is now there. It will have to be formatted and have a driveletter for this part to work. Jump down to Disk Manager and see if it is there. You may have to Rt. Click and import it as a foreign drive or Rt click and give it a Driveletter ;-) If it is not, use a shorter, thicker (more wires) USB cable and try again.

Windows doesn't like Any HDD without win signatures on them - aka:'foreign disks' so ANY time this happens, if OS doesn't see it, use disk manager and Import it, then Rt click it and give it a Diskletter.

Installing wd 750gb ext hdd

in 'My Computer' do you see a new drive appear like E: drive?

If so this is the drive you have attached. If you cannot put files on it - it may need formatting. Right click on E drive and choose format - Click Start. Once completed you should be able to drag and drop file on to this drive.

Format 320 GB HDD problem

Have tou tried the mangement in windows, My computer> right click>manage, then disk management and then right click on your hard drive and then one of the options is to format. Although only 127gb will show and the rest should show as a seperate partition, do the same with this to implement it. If no other partition shows you may have to upgrade your motherboard bios to suport large capacity disks.
