Public bug reported:

WDC WD7500BPVT 750GB Advanced format HDD
changing dirty_ratio or dirty_background_ratio prevents freezes but it slows down HDD R/W operations
deadline scheduler is selected
parted informs that partitions are aligned
logical sectors are 512B while physical sectors are 4096 bytes
hdparm informs speed 96MB/s
Programs startup is slow.
S.M.A.R.T assessment is OK.

HDD operations make system unusable.
