Bad Hard Drive

[FAKHAR]

Hello,
My drive is 2TB WD Caviar Green.
Full Model is WDC WD20EZRX-00D8PB0
NTFS-MBR-NON Boot
This is my data drive and have very important data on it. I am using OS Windows 8.1 on SSD. Some days ago my drive suddenly crash after reboot. Windows was loading very slow and after loading windows i checked the smart status that shows me that there are 1600+ bad sectors. Now this drive is readable through windows but copy speed is very slow and its partitions loads 10 mins after windows. Its copy speed is very slow round about 900 kb which is very painful. I only want to copy data from it. Please guide me, how to copy data from it with high speed and even it is possible to copy on higher speeds or not? I have tried ddrescue and clonezilla but clonezilla is not cloning my first 2 drives gives some error and both software are giving finish time like a month.
Please tell me efficient and good tool to copy data. One of them drive is BitLocker Encrypted.
Here is a power shortage in our country so light goes after every 3 hours for 1 hour. So I can not copy data for long please suggest me any way or software to copy my drive.
I have also tried Linux boot discs but those were not detecting my drive.
And also tell me the cause and problem with my drive. There is no clicking sound or any type of sound coming out of it.
Running chkdsk or hdd regenerator make condition good or more worse? Please answer it too.
Thanks in advance.

Avoid CHKDSK, HDD Regenerator and SpinRite.

Instead apply the "slow fix" and then use ddrescue.

Thanks for your reply. Is there no way to copy data from any bootable File managers or something like that. I mention the issue of load shedding.
I forgot one thing it disconnects on windows after 15+ mins.

Ddrescue can resume after an interruption if you enable a log on a writeable device, eg a flash drive.

Please give me command according to my condition that saves log on usb.
Last time I used sudo ddrescue -v -r 3 /dev/sdb /dev/sda logfile from Ubuntu rescue remix cd but I cant resume after interruption, it always start from 0.

I didn't understand the slow fix issue. Is it the use of chkdsk command with /f or something else please explain.

there is common FW problem with western digital drives "slow responding"
the best and free option is ddrescue.
BTY which city you are from ? may be we can help.

good luck

The "slow fix" involves editing the drive's firmware. A tool such as WDMarvel (US$100 outright or US$10 for a one-month licence) can do this.

As for ddrescue, you need to mount a writeable medium such as a flash drive and then specify a logfile on the mounted volume. You may find that Ubuntu automounts the flash drive, but I haven't tried it.
