It took 6+ hours to scan and mark the approx. 6GB D: partition. I really needed that area of data to be a primary partition. So thinking DD had written the info on the bad blocks to a partition table somewhere, I ran Partition Magic (at this point having upgraded to 8.0) to convert the D: logical drive to a hidden primary drive for doing tests with various flavors of Win98.
*blink* *blink* OK I missed something ... why do you need it to be a hidden primary?
I have a habit of keeping partitions with different copies of Windows OSs hidden from each other. I seem to recall warnings about doing this in order to prevent one getting into the other and playing havoc.
Ah IC ... OK it makes sense now :-)
Hmmm... the 2nd run through didn't report any problems even though I heard the drive scartching away at a few classic spots in the process. And the 1st error log that found problems was wriiten over with a blank one. :-/
Off for a 3rd try... then maybe another run at NDD marking the bad blocks.
Without an error file reporting failure code of 0x70 representing a "Defective Device", I won't be able to return it for a replacement for another to fail again... :-/
Nah that doesn't matter, you don't actually need that file to prove anything, I brought it in just in case the store came back with a "It looks OK" when they plug it in ... IBM's service center will be able to tell in an instant if the drive has that bug (IIRC those drives actually have a bit of flash memory on them that stores error codes and it would have had that error written to it somewhere).
If that fails, it'll tell you if it is the dreaded 75GXP bug in which case the drives are pretty much a writeoff, the bad clusters will slowly keep increasing in number, taking random chunks of data with them (at least thats what happened in my experience) ...
How 'bout herding the bad blocks into a hidden partition and not using it. Think the cancer will spread anyway?
I think the cancer will spread anyway if it's got that bug ... it certainly did for me. On the flipside, I've had two other drives (not 75GXPs) where I've partitioned around bad clusters and they've been fine ever since (they've been going strong for at least 2 years since!).
PS: As I recall, there was a problem with these IBM DeskStar 75GXP drives. Wonder if IBM will replace it gratis 2+ years after the purchase.
....replacements! Given that the 75GXP is long since discontinued, you might get lucky and get 120GXPs or better :-D
Oooo... that'd be great! I've probably got about 9 months to go on the 3 year warranty.
Better jump in quick then so you've got as much warranty cover on the new drives as possible to test it, IIRC the replacement drives get the remaining original warranty or 3 months warranty, whichever is longer.
I'm running NDD after the 3rd run of DFT found no problems in 1/10th the time the 1st run took and about 1/5th of the time of the 2nd run for some reason. Will report back later
Probably because it tried to reallocate (I think at least one model of IBM IDE drive does some reallocation like high end SCSI drives do) and it detected that the drive knew it had problems? *shrug*
Good luck!
