Hello, I own an HP 6730s notebook running w7 32bit. the hard drive had just 19gb of space left, so I decided to get an external Hard drive (WD Elements 1TB).
I succeeded to transfer some data into the hard drive and freed about 30gb but the process froze midway until I had to restart. But it got sour and cannot restart.
Start up repair prove unsuccessful after two attempts running for about 6 days.
Trying command prompt, I realised it started in drive X instead of drive C and going further to view all drives present I can see all the drives C, F and H plus drive X which I did not have. Drive C however cannot be accessed with the message "command cannot be performed due to an I/O error"
Is there a way I can recover my data from this C drive or repair the hard drive? will appreciate some help.

I was using the copy/paste command after creating 3 partitions. My intention was to transfer all my documents to one partition, hen do a full backup on another partition. But transfer could not be completed. presently the computer doesn't start, it flashes the blue screen and restarts when I attempt to start normally. Thus I cannot access the HDD even using another computer.

The bad drive's model number is WD250BEVT-60ZCT1. I haven't used CrystalDiskInfo yet, but the bad drive is not detected on another computer.
Reinserting the HDD into the laptop and running start-up tests gives a hard drive failure report with the following info:
FAILURE ID: OK7U84-0007JS-XD6XGJ-60SV03
PRODUCT ID: KU359ET#ABF
HARD DISK CAPACITY: 250GB
HARD DISK 1
Is it possible to view the SMART REPORT before startup?

ISTM that the "startup repair" may have killed the drive. When WD's drive develop head or media problems, this often results in damaged firmware modules (eg SMART, defect lists, LBA-to-CHS translator) in a hidden system area on the platters. The drive then fails to come ready. I'm not aware of any easy DIY solution to your problem. :-(

Oh no, isn't there any possibility for me to recover just the data in the drive. I can actually get another hard drive later but I don't want to think I lost everything.

Please I got another development on the bad drive.
It is not recognized by another computer when connected through a USB cable but I reinserted it into its original computer and opens command prompt before start-up.
Here using DISKPART, all partitions are seen and are "healthy" with the right size allocations, but the C drive appears as RAW.
Am I wrong to think that "Healthy" means good? and why is it not being recognized on another computer?

"Raw" means that the OS cannot under the file system. This usually means that one or more of the critical sectors is damaged, either logically or physically.

If you can see several partitions on the same drive, then this means that sector 0 is readable. That's where the partition table lives. This in turn means that the C: partition has a corrupt file system, either due to logical problems or physical ones (eg bad sectors). A SMART report should tell you the physical state of the drive.

If it's a physical issue, then I would clone your drive with a tool such as ddrescue, but I would first apply the "slow fix":

You can also purchase a one-month licence (US$10) for WDMarvel to "deal with slow responding".

Thanks for your responses. On command prompt, the DVD ROM (drive F) is sector 0 while C partition appears as sector 1, and the other partitions follow in serial order.
I'll try the slow fix and revert.
Thanks again.
