Re: [hard drive] Cloned drive... now hanging issues That information helps a lot -- thank you very very much!
Attribute 0xC5 is what I referred to as "suspect" or non-readable LBAs. That means you had (actively) 2 LBAs which couldn't be read. So Spinrite telling you there were no errors is hilarious -- there were absolutely 2 LBAs (1024 bytes total) it couldn't read. These LBAs have not been remapped yet -- they're "pending" to be analysed by the drive, which as I described, is only done when a write is issued. Macrium should have told you the same. How a program handles an I/O (read) error is up to its code -- most tend to fill the unreadable portion with zeros. There is the possibility that the firmware on the drive is buggy (have seen this many times) and that the number (2) should actually be zero.
Attribute 0xC6 is a counter that tracks the number of sectors which when reading or writing to, failed. For reading, this means the ECC portion of the sector couldn't be read or couldn't be used to auto-correct the data. For writing this means a sector which is just downright screwed -- as in dust on the platter, a magnetic substrate anomaly (surface damage), or something along those lines.
Anyway, my point is (with attribute 0xC5) that there's a chance the lost/unreadable 1024 bytes of data could have resided in something like a device driver file, or something "key" to the OS itself thus causing you the problems you're having now. The only solution is a checksumming filesystem, or since there isn't one for XP, reinstallation. :-( I know, it sucks. This problem affects most OSes though, barring those with checksumming filesystems.
If you're at all concerned about the health of your current drive (the Toshiba), please install HD Tune Pro (trial version is fine; please do not use the Free version) and provide me a screenshot of the Health tab and I can tell you if there's anything anomalous there. You may need to resize the window to make sure all the attributes are shown.
Sorry I can't be of more help.
