Hard disk challeging problem!Need help!


Feb 23, 2012
Hello guys,I would like to describe my situation briefly. I have an Acer aspire 5920g laptop. Before some days I experienced the black screen of death. I tried to install the os from a DVD backup/acer restore point. The restoration failed. I tried to reformat the disk via DOS. I bought a new internal disk and I installed vista and linux mint.
I also bought an external connector to connect my previous faulty internal disk to a usb in order to save my D: partition that has data. The disk is not able to initialize (cyclic redundancy check). Moreover is not readable its capacity and format from win disk management. From data recovery programs (the ones that can recognize it) I get totally wrong capacity. The hard drive is WD 250GB and the program recognize it as 2TB!!
I cannot do anything on this drive (format etc).
My questions:
I've read somewhere that if the hard disk shows wrong capacity I am not going to be able to recover data.Is it true?
Is it better to use linux to recover data somehow?
In c: was the os and d: the data. I can't see any partitions or volumes at dos (and in third party programs).The restoration is supposed to format the c: volume,where is d:?
I don't care about the drive, I need some of the info only.The easeus data recovery needs some hundreds of hours to scan the disk and I am not even sure if I am going to get a result.
Any suggestion is welcomed!
It appears that your HDD has an internal fault, possibly a bad head or a firmware problem. WD drives often suffer from corrupt firmware modules.

If you feel capable, we could try to read your firmware MODs using MHDD ver 4.5. V4.5 supports scripting whereas V4.6 does not. You would need to connect your drive to a SATA port, and that port would need to be configured for IDE mode, preferably legacy or compatibility mode. Let me know if you are prepared to do this.

Otherwise, here is an online diagnostic service that may be able to identify the faulty module:

AFF Repair Station:

Diagnosis is free, but repair, if possible, costs US$50.
