So there is the case: I’m using WD external drives for quite a long time (totaly I own 14 of them). Recently I’ve noticed slight incresing of 01 (“Read error rate”) and 197 (“Currently Pending Sectors”) S.M.A.R.T. attributes on two of my external HDD. According to the Ashampoo HDD control RAW values (in DEC) of (01) and (197) attributes now are:
(01) - 2
(197) - 2
(01) - 1
(197) - 6
HDD are being used for one year at the moment.
It seems Both HDDs work fine - no screeching noise or whatever. Managet to do backup of both HDDs without any problems. Values of attributes (01) and (197) so far are stable - neither increasing nor decreasing. I’m a bit worry about (197) attribute, normally for WD it should be on zero. Last time when I’ve got (197) rise on My Passport it ended with HDD death, but that was quite different case - there were screeching, constant rising of (01), (197) and (200) attributes.
Both HDDs were tested by WD LifeGuard and WD Drive Utilities - extended test showed no problems.
So my question is - is non-zero (197) attribute is an occasion to worry?
Should I call RMA now or just watch over this two HDDs for a bit?
Sorry for my rough English.
