Question about Western Digital 250GB MyBook External USB 2.0 250 GB Hard Drive

1 Answer

No Allocated letter on HDD

I have a two year old PC that was running its original installation of WinXP pro SP2. I have an AMD 6400+ Dual core Processor and 2.5 GB DDR2 RAM, NVidia Geforce 7600 GS 512mb GPU and a 250 GB SATA 1 HDD.
It's the HDD that's giving me the headache. Boot times had reached 5 minutes plus! No matter what I did I couldn't reduce it. I had a lot of Photo's and music on the drive so unless I copied it all to DVD I'd loose it all on re-format.
I decided on a different solution and bought a second SATA 1 drive, 500 GB. Using a fresh WINXP Pro installation on the second drive, I placed it in SATA slot 0. I placed the original drive (250GB containing all my wanted data) in the SATA slot 1. This worked a treat and I was able to boot the PC and access all my data from the old drive without a problem.
As luck would have it the new installation developed a bug with the desktop and it seemed quicker to do a second fresh install of WinXP pro, than try and fix the bug. All went well except on completion the old drive didn't show up under 'My Computer'.... Nothing at all! However, if I went into 'Device Manager' it was there and was showing as working perfectly, (Which it certainly wasn't). Also, if I went, Control Panel / Administrative Tools / Computer Management / Storage / Disk Management, there was the HDD showing but no drive letter was allocated to it. Right clicking the drive did NOT bring up the option to change the drive letter or path.I tried removing the old drive altogether and reformatting the new drive and doing another WinXP pro install. Then re-connecting the old drive. Same result! I then bought a caddy and mounted the drive in that, hoping Windows would see it through a USB port as an external drive. No luck!I can pull data from it with a drive resalvaging program but its a mess. There is no file tree at all. Everything is completely random, plus every graphic the PC has ever seen is there even viewed web pages and the job of sifting through it all is endless. Also any file that spans two sectors is chopped in half so most of the recovered music is useless.
Can you help please?

    Thanks for the advice but if I boot from a second drive I can't scan the old drive as Windows XP can't "see it." Nor can I run an antivirus scan for the same reason. I shall try to "fix" the mbr and see if that does the trick.

i think you lost the mbr of old hdd. Or you have a virus problem on your pc. firstly you boot the pc with new hdd and then scan the whole drive by an updated antivirus and then boot prom old hdd. if it is not solve your problem then rebuild the mbr by any software which are avalable on net.
i think it can solve your problem.

SMART failure predicted on hard disk 0:

There is a big problem with newer conponents and Win XP versions prior to SP2. Especially with newer motherboards.

You have to make a bootable SP2 disk if you don't already have one. To do this use the slipstream proceedure specified on the Ms website. Many other websites describe the process with easier language.

Slipstreaming is a common practice now. Essentially, you copy your original install disk to the c: drive then download SP2 to C: drive then download the slipstream utility from MS. Running the slipstream utility then inserts the proper drivers (ide and HD drivers too) into the licensed copy you have. You then create a bootable disk from the slipstreamed files you have.

This approach is resolving alot of blue STOP errors and SMART errors.

ALSO, you want to make sure you are installing any drivers provided by the MB manufacturer AND Drive maker.

Good Luck

Seagate sata hdd error

Quick format removes files from the partition, but does not scan the disk for bad sectors, while a normal format does that. That's why the formatting takes so much longer.
You should definitely check your drive for bad sectors by issuing "chkdsk /r" in the command line, which scans for and attempts the recovery of bad sectors.

If there is a bad sector somewhere, your system might crash at any time and it might be at a very inconvenient moment.
If you find bad sectors, you should consider replacing the drive
