January 16, 200917 yr Hey guys, My freind dropped my Parity HDD, she feels really bad for it, and accidents do happen so ill let her off:) ....anyway, it dropped about 30cm onto a glass table, i immediately fired it up and all is ok (it sees the drive, and no error when checking parity) .....please tell me a good application i could use to do a stress test on the HDD, and see whetehr or not its worth keeping in my array now, preferably something that will run overnight to check full integrity of drive. I have a flopy disk drive installed, so a dos app could work fine aswell, so long as i can specify drive letter:) Thanks, bad day for me today:(....
January 16, 200917 yr I would think you could do a long smart check...it will take from 2-4 hours to run smartctl -d ata -tlong /dev/sda Or check out the post from Joe L on preclear. You could it a few times but then you would need to rebuild parity. Erik
January 16, 200917 yr Good answer. I would obtain a SMART report first, for comparison with a SMART report *after* you test the drive. The SMART long test is a good health test of the entire drive and its mechanics and surface. For the most thorough test, also do the pre_clear script with multiple passes, and it will provide SMART reports at the end. With either test, you will know from the final SMART report if the drive is fine. As was mentioned, the pre_clear will require the parity drive be offline, and be rebuilt after testing.

Your female friend comes over and wants to play with your parity drive. You did have a bad day. ;) :o ;D (Sorry, couldn't resist)
January 17, 200917 yr I am afraid to ask how could such a thing happen. - Your parity disk is OUT of where it should be. Check. - There is a glass surface in the geek corner (unacceptable except if it's for some geeky construction). Check. - Girlfriend in geek corner (unacceptable except if she is cool with MMORPG and you cooperate, or if there is a case of sexual act involving webcams). Check. - You let her touch your part. I mean your parity disk. Check. ...of course disk goes over glass surface. ...of course she drops it. I hope at least the "sorry" was the proper one for the situation. (and yes you are allowed to pretend that she broke it, until acquittal is granted)
January 17, 200917 yr FWIW, The drives are designed to handle a certain amount of G's for situations like this. As long as it wasn't spinning chances are you are good. Smart long test as below is recommended. A pre-clear cycle, followed by a smart long test would also give peace of mind, At the very least, I would re-build parity on the drive just to be sure no bits fell off the platter
January 17, 200917 yr Indeed current hard disks (but 2.5" more than the 3.5" breed) can handle such things - usually.

(Whenever a SMART drive fails, it always predicts failure within 24 hours. You may have longer, but get the data off it ASAP.) It keeps having to re-try to spin the drive up to speed. Must have jarred the bearings or something. Next time, if you drop the drive, drop the drive from a distance less than 30 cm. (Nearly 1 foot... interesting...) Joe L.
January 18, 200917 yr Author Recently ive noticed....that even though the disk is set to spin down every 15minutes....it doesnt (theres definitely no read/writes to it aswell... Is this a sure sign that the disk has started to fail, since it doesnt want to spin down no more? Thanks
January 18, 200917 yr Author Im transferring files off it still....should be tommorow before replacement.
January 18, 200917 yr Im transferring files off it still....should be tommorow before replacement. I thought you said this was your parity drive. (No files to transfer off parity).
January 18, 200917 yr SMART overall-health self-assessment test result: FAILED! Is this a sure sign that the disk has started to fail, since it doesnt want to spin down no more? The drive is destined to fail in the "near" future just by reviewing the SMART report. If it were just a bad sector, you would be ok for a while, but the spin_retry count is showing issues too. take appropriate action if you have data on the drive.
