Hard drive issue
Hey friends, been a while since i had to ask for help but here i am .... Ok so here is the problem : i have 2 Seagate hard drives, both at 160gb each, these used to be in a raid 5 with 2 more of the same drive (4 total drives in the raid) i recently broke the raid up because i went to SSD's for OS and important applications and am now using 2 drives with no problem for storage, the other 2 that i am having the problem with is this : windows reports a cyclic redundancy check error and is reporting each drive as having 298.10gb of storage when in fact they are not that size. i have no data of importance that needs to be recovered from these drives so any kind of data destructive repair is ok. i can not run a chkdsk on these drives as windows will not assign a drive letter, disk management is unable to format the drives. these drives are just shy of a year old. i am needing these drives to do a new OS install to replace a completely failed drive in a laptop. So there it is, my problem. if there is a solution i am all for it if not i will have to RMA these things i guess. Thanks in advanced for any insight any of you may have. |

How about you boot off ,say, a Linux Mint live CD and run a disk manager. Will you be able to see/repartition/format the drives? |

So there it is, my problem. if there is a solution i am all for it if not i will have to RMA these things i guess. Thanks in advanced for any insight any of you may have. I could understand the OS seeing 298.10gb if the drives were in RAID 0, and you were using Intel Matrix RAID. But a single drive should never be able to report a capacity that goes past the physical end of the disk. The ATA/ATAPI command set supports SET_MAX_ADDRESS for setting a Host Protected Area. That would allow trimming a 160GB drive so it was 120GB for example. But SET_MAX_ADDRESS should not support setting the declaration of drive size, past the physical limits. As indeed, you'd get a CRC or other kind of error, as soon as the operating system tries to read that area of the disk. It makes no sense, for a drive to support such a thing. ******* What you could try, is to take the "defective" 298.10GB drive and actually make an HPA on it, use SET_MAX_ADDRESS and define a smaller drive. Then, the CRC errors will stop. http://en.wikipedia.org/wiki/Host_protected_area You boot a Linux LiveCD, and use hdparm. If you attempt to set an HPA, you can only do this once per boot session. Additional attempts to define the capacity, will require a reboot of Linux. I feel this is actually a feature of the hard drive - the hard drive refuses to accept more than one of these commands per session. hdparm --yes-i_know_what_i_am_doing -N p# /dev/sdX To determine what number of sectors to use, examine the capacity information of the existing disks. You can try "dd --list" on the working hard drives. This is a Windows program, and you can run this on the Windows machine having the remaining two "good and working" disks. http://www.chrysocome.net/dd ******* Not every disk interface on a motherboard supports HPA commands. On my current P5E Deluxe motherboard, only the Jmicron IDE chip allows it. The BIOS module for the Southbridge SATA ports, appear to be locking out the command. When I wanted to set an HPA on a SATA drive here, I used an IDE to SATA adapter dongle and connected the SATA drive to the IDE controller. And then I could issue the "hdparm" command from Linux. The capacity change from SET_MAX_ADDRESS is persistent across power cycles, so when I trimmed my drives down to 6GB and 4GB as an experiment, they would have stayed that way until using the "hdparm" command again later to correct the size. ******* The ATA/ATAPI spec supports "Secure Erase" option. Under your current circumstances, I would not try this on the drive unless you were absolutely sure it wasn't in RAID mode. And all other attempts to make the drive work, had failed. There is no magic about this command. If the control information on the drive is corrupted (unlikely), then a Secure Erase would get just as many CRC errors as your OS is seeing, and then the Secure Erase could stay "stuck" in that mode... forever. http://cmrr.ucsd.edu/people/Hughes/Secure-Erase.html Before using that program, *read* all the documentation! A password is set on the drive when you use Secure Erase, and using a wax pencil, write the password on the body of the hard drive for future reference (for the next Secure Erase attempt, using some other software).

Hi, A couple of possibilites come to mind to get your Seagates to be seen by Windows again for drive letter placement. I'd download and run Seagate's diagnostic tool 'Seatools for Windows' and check that the drives are OK or allow a repair if they aren't. Running a low level format if possible may get them back into running order and allow Windows to see each one properly. If Sea Tools doesn't pass the drives then I would be inclined to look for a RMA for replacement. The other thought is to get a partitioning program such as Easeus Partition Master Free http://download.cnet.com/EaseUS-Part...-10863346.html and see if it will delete the current partitions to allow creating new ones. -- Jan Alter |

ok so yea i have booted off UBCD and ran several diagnostics on these drives, surface scans, remaps, have partitioned them so on.. so on.. so on.... the drives are still show with the odd storage amount and a cyclic redundancy check error.... |

You write that disk management won't format the drives but what will it do? For example, does disk management 'see' the drives at all? If it does does it show any partitioning? If it shows partitioning of any sort then it should be able to kill the partitions and that may give you a starting point. A quick destructive fallback would be to run Linux from CD and use it to zap the drives to a null state. Or use the Seagate tools as someone else suggested. Or use DBAN to lobotomize them. |

Can you just plain delete them by using Disk Management? I'd do that and recreate. Otherwise I'd disconnect all drives but those two problematic ones and boot from a utility cd that contains dban or some other disk erasing utility. these drives are just shy of a year old. i am needing these drives to do a new OS install to replace a completely failed drive in a laptop.
