Hello! A friend gave me a WDC WD7500BPVT-80HXZT1 hard drive, which has got some problems. The aim is not to save the data but to use it as a hard drive without buying a new one. I do not own any of those expensive hardware/firmware tools or professional softwares. I was looking for a DIY solution using, if possible, free software only.
First of all, this is my S.M.A.R.T. table:

After a complete MHDD scan I found out that an area of the hard drive looks terribly damaged (physical damage?): blocks have high latencies when read and some give errors. You can see by yourself the MHDD scan result by opening this file:

File comment: MHDD scan report
WD7500BPVT.zip [227.36 KiB]
Downloaded 452 times
which has been generated from the ADVLOG.BIN file using a program I wrote. It contains HDD's info, scan summary, speed map, warnings and errors (along with block number).
I tried several times to low-level format the drive and see if the bad blocks decreased but when the damaged area is going to be formatted, the HDD gives ABRT errors and it is not detected anymore from the PC until I manually remove and re-insert the power connector again. Same thing happens when using REMAP or ERASE functions in MHDD.
As a "solution", I thought I could repartition the drive by excluding the damaged areas and then using the good partitions for personal use.
I am quite "new" to the hard disk world, so it would be great if you can help me step-by-step.
Thank you in advance,
