defective weak and bad sectors and drive needs to be replaced.
in theory mapping out a couple bad sectors with the right utility (not Disk Utility btw) might buy you some time or to use as a rare achive drive.
Buy enterprise. Buy quality. Scan drives before using, no guarantee they are perfect as shipped.
Use WD Lifeguard in Windows to do a full extended test and to zero out the entire drive is one of the best.
Go for WD 10K VR 1TB $220 for instance.
Windows is more likely to note RAM and sector errors actually and no NTFS is not causing and an OS can't, though faulty RAM can cause a file's contents to be garbage.
Invest in Paragon Clone OS... as I mentioned once again.
hi hatter. thanks a ton.
i will look into buying the velociraptors from now on. i /do/ have the Black Caviar drives for my 2 - 2 TB drives and the the drive i have is listed as failing is a "1 TB WDC WD1002FAEX-007BA0 Media" which is think is this drive http://www.newegg.com/Product/Product.aspx?Item=N82E16822136533
so if i am following you, from now on you would recommend that i zero out the drive and then run a DISK UTILITY scan on the drive after formatting is that right? or is it better practice to zero it out and then to run this Tech Tools surface scan on it?
also, if i run a Tech Tools check on RAM and it checks out OK i just chalk these two drive failures as bad luck??
That drive should be fine, is new-ish, RMA WD based on serial number.
The 10K models are $130 more though.
No to DU to zero a drive, better than nothing but you have Windows, you can run WD's own utility which is much better (works on non-WD also)
TTPro is not really doing you much good.
Do not use two tools - too much salt as they say - for the same soup - like scanning for SMART and disk errors. Use one or non (and do so from a not main system used for maintenace).
Buy and use SoftRAID to format your drives and esp. for RAIDs. Scans for those weak sectors.
SMART Utility got mentioned for checking for and mapping out bad sectors.
TTPro for RAM? no. AHT, yes when you buy. Monitor temps. Replace with newest FBDIMMs they are colder running by 10-15*C Memtest or Rember
I would have a lean mean system, no TTPro, monitor temps if you must, maybe boost the fans with Smcfancontrol 2.4+
Nothing non-essential is best.
Lifeguard can also detect a bad SATA data cable connection. Rare but happens, even in Mac Pro where cables got loose.
hi. i am not following a lot of this since it seems very technical and is too abbreviated a presentation for me to understand.
that said, i have /one/ WD 1 TB blue drives that have Lion installed on it with the Windows 7 Boot Camp workaround described by that url i got from you which failed in the last two or three months and i just now had a SECOND drive (it was simply a daily Carbon Copy Clone of the original drive described above) which failed within the last two weeks.
i am pretty sure i had one other new WD drive (a 2 TB black caviar one) fail in this machine within the last year and this seems like a tone of drives failing.
not sure i have anything special going on and the method of failure detection is simply Tech Tools reporting bad sectors which i am told is in fact indicating failure...
am i missing something?
also on this:
"No to DU to zero a drive, better than nothing but you have Windows, you can run WD's own utility which is much better (works on non-WD also)"
you are saying that downloading WD software is going to let me zero out my drives better than Disk Utility does? if so, how do i use this? i have mac OS and boot camp on my OS drive and MAC OS on my data drive and then i have two clones (one clone of each of these). you want me to d/l WD software while booted into Windows somehow before partitioning the drive or using DU to format it for Mac? i don't understand this very well apparently...
