Re: WD actually listens?
RPM is pegged as "Intellipower"... could that mean those are 5400RPM as with the green drives (only time will tell, maybe)? And a MTBF of 1,000,000 hours is kind of unusual in juxtaposition with a 3 year warranty (IMO), even though MTBF says little about lifespan by comparison. Good to see the red drives are rated at 600,000 load cycles like the WD notebook drives and VelociRaptor drives, too.Last edited by Wester547; 07-10-2012, 06:35 PM. -
Re: WD actually listens?
But how does it handle errors?
Does it go away and contemplate life for many seconds and cause the RAID controller to fail it, or do they allow it to let the controller handle the error?
These days drive manufacturers make you pay the "enterprise tax" to get that "feature"36 Monitors, 3 TVs, 4 Laptops, 1 motherboard, 1 Printer, 1 iMac, 2 hard drive docks and one IP Phone repaired so far....Comment

Re: WD actually listens?
Green WD are rarely 5400 rpm
In their papers they said they're factory set at speed between 5400 rpm and 7200 rpm, depending on how good the motor is and where they find the motor won't go over a certain wattage.
I personally heard the majority are at about 5800 rpm.
Seems like this is the case with these drives as well, check the datasheet:
Intellipower = A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance. For each drive model, WD may use a different, invariable RPM.
Other than this, apparently they have some NAS related stuff in firmware - maybe stuff that can be used with some NAS boxes that license the tech from WD.Comment

Re: WD actually listens?
I was always of the impression that "Intellipower" was just an opulent front for being 5400RPM. If I remember correctly the Green drives always vibrated audibly at 90Hz (5400RPM), whereas 7200RPM drives vibrate at 120Hz in terms of sound, though I could be wrong on that. And I don't see how "Intellipower" could be a power saving feature since varying between 5400RPM and 7200RPM defeats the very idea of doing that. ^^; (spinning up and down a drive costs the most in terms of power) I also thought that it was physically infeasible for a drive to "change" its RPM speed in any other manner other than spinning down and up completely (like a drive going to sleep and being "woken" up), for the same reason why users cannot set 5400RPM drives to operate at say, 4200RPM.
I might be wrong, but I thought for sure that like Scorpio Blue drives, all Greens were 5400RPM and Intellipower was just marketing prattle. Needless to say, I don't know what "Intellipower" means in the case of the Red drives; it could mean 5900RPM or anything like.Comment

Re: WD actually listens?
This is just RE edition cut down to 5400RPM... Wonder how much they'll be.Comment

Oh wow.
As in the other thread I was trying to revive/re-bootstrap an old Apple IIe and wasn't successful reading or writing any disk. Both drives behave similarly.
Then I was wondering, what about my PC floppy drives? I have a HH 5¼" HD drive and a combo 5¼+3½ drive. I tried formatting the disk that wouldn't work in the Apple and it didn't work in the PC either!
Then I tried a HD 5.25 disk ... it won't even touch the disk either! Just like the Apple DD disk, "Not Ready!"
Weird. Seems the PC drive is having trouble clamping... -
With the discussion about water pumps failing when cars sit for a while, I wonder what people have seen with hard drives. Do people see hard drives failing after being sat on the shelf for a long time unpowered versus a hard drive that's at least powered up at least once in a while, say, weekly?
Wonder if it's worth spinning up the spare spinners once in a while to keep the bearings lubricated?
Wonder how I should best keep my cold spares for my RAID "fresh" for eventual failures of the working drives. Was thinking about keeping a hot spare but that's another... -
I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.
Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present... -
i have several dead/bricked (not detected, doesnt show up or making constant clicks of death) and faulty bad sector hard drives. im moving house soon and need to get rid of some dead weight.
i thought of selling them for parts or not working but they are quite heavy and shipping each drive internationally via local post is US$23 each. im using some of the drives as gym strength training dumbells by putting 4 of them in a box to make a 3kg dumbell. but since im moving i cant carry the deadweight with me. any ideas what to do with them that is cost-effective for ppl like me... -
Recently I was given for free a Sony RCD-W3 with the following symptoms, CD recorder drive reads CDs without any issues (haven't tested recording function yet because I don't intend to burn CDs on that machine) but the reader drive shows disc error after some seconds of it trying to read CD. Tried both CD-Rs and commercial audio CDs with same results.
First thing to do was to clean the lens but that didn't change anything. Googling the issue revealed that this is a common issue on several Sony CD recorder machines and the culprit is SMD electrolytic caps located on the PCB bellow...05-05-2024, 02:04 PM
