[QUOTE="espi, post: 1250047, member: 204100"] Er... just checking that I'm understanding you here: this procedure would test to see if the external drive has a healthy boot sector, yes? Re. the PCI card: it appears to be OK. I've checked all of its ports and it's connecting fully with other devices (flash drives, scanner etc.). This morning I did a command-S and ran Applejack on the system drive, and all went well. The machine appears to be working perfectly - it just can't mount that external drive - so it is starting to look like it's the drive or possibly the caddy that's compromised. Thank you both for your continued input on this, it's really helping. ADDED LATER: I am now at my friend's office and have plugged the external drive into his iMac, running Snow Leopard. At first it didn't mount, so I went into Disk Utility and hit the "Mount" button. A dialogue box came up telling me that the drive (or was it the volume?) could not be repaired, and that it would be mounted "with limited functionality" (at least I think that was the wording - I tried to get a screen grab, but the message disappeared before I could). Also, another box came up asking if I wanted to backup the drive with Time Machine. The drive then mounted. I opened it and tried doing some write functions on a few unimportant files - and so far, all my file modifications appear to have been successful. Interesting! Clearly Snow Leopard is pretty good at making compromised drives accessible. I'm not sure what the "limited functionality" is, TBH, as everything I do to files on the drive appears to succeed. I've just tried "Verify Disk" and "Repair Disk" on the volume, and it tells me all is fine. I'm not getting up any false hopes that this has somehow magically fixed the drive - no doubt when I get it home, I'll find that Panther still can't mount it - but at least I now know that it is the drive that's got the problem, and not my Mac! ...or at least, let's hope it's just the drive... :D [/QUOTE]
