Cant access some of a Partition
It appears that one of my hard drives is going to crap. It's my second
(slave) drive, which has 3 partitions on it. 120gb IDE drive. Formatted to Fat32. This is a Win98se computer. Oddly, from Dos, I can see all the folders in that partition. From Windows, I only see about half of them. This partition contains storage files. Most are backed up, but there is a large folder containing some valuable info that I do not have backed up. In fact I first noticed this problem when I wanted to backup that folder to am external HDD. I ran Scandisk, first the fast method, which told me to use the thorough method. I ran the thorough one, which took hours. While running, it got to one cluster and said that one can not be fixed. The rest of that partition tested ok. When scandisk ended, it said that it could not fix that one error, and when I tried to close Scandisk, Windows locked up. Temporarily, I removed that drive. Since it's all storage, I can still use the computer. I intend to buy another drive of the same size and type. However, I really need to save that data, especially that one large folder, which contains many sub folders. Like I said, I do not see that folder from Windows, but I can see it from Dos (I dont understand that). Of course in Dos, all the filenames are truncated. I can either stick it back in this computer, or probably connect it via USB to my XP laptop. What software can I use to extract the data I want to save? I do have Partition Magic (not sure if that will help). If there is a bad cluster, I'd expect a few files getting lost, but I cant see many of the folders that according to Dos are still there. Please help!!! Note: I am not a Linux user, but maybe I could connect this drive to another computer and boot that computer with some smallish linux such as Puppy Linux, from a bootable USB. I have used that method to retrieve data from an XP drive, after the motherboard failed, but I never tried it to retrieve data from a failing HDD. |

That's the exact method I would suggest, although there's no real need to use a separate computer: connect the new drive and the old drive to separate controllers (not master and slave on the same controller), boot from USB (or CD if the computer is too old), copy. But I'm not entirely convinced the drive is failing, aside from that one bad cluster. If you have a util that can check the SMART data (most modern BIOSes can) I would start there. You could also connect it to the XP machine and run chkdsk on it and see what happens. Or, with that same bootable Linux USB/CD/whatever, run fsck.vfat on the bad partition (i.e. 'fsck.vfat -aft /dev/hdb1', where the switches tell it to a: automatically repair the filesystem, f: salvage unused cluster chains to files, and t: mark unreadable clusters as bad). -- One died for power. One died for lost love. One greeted death like an old friend. |

The computer is too old to boot from USB. (from the year 2000), and it dont have a CD drive (I have no need for CDs). I dod have another desktop computer that has XP installed. But that is a much newer machine and it has some other kind of drive, (not IDE). I think it's Sata or something like that. So I dont think I can just plug this IDE drive into it. My guess is that the easiest way is to buy one of those kits that allow any hard drive to be converted to an external USB drive. I plan to order one of them from ebay today. I dont think the whole drive is failing either. It has 3 partitions. G: H: I: (H: and I: work fine). But I think once a drive starts to show bad clusters, it's starting to fail, and I should replace it. What sort of utility will check SMART? The Scandisk.log file shows the bad cluster is NOT being used, so nothing should be lost. I can only figure the problem is in the MBR. Just for the heck of it, I loaded Partition Magic, and PM showed that partition to be filled to capacity. Yet, going to My Computer and showing Properties for that G: partition, shows it's only half full (which I know is true). It's a 50gb partition and contains about 24gb of data. Although I can boot to linux on a machine that boots from USB, I get completely lost when it involves the linux command line. I can only do the basic GUI shell. I found that I can copy my data from that bad partition to another partition, using DOS, but the folder I need to save, contains several hundred sub folders. I dont mind copying each one folder by folder, but all long filenames are going to be lost, and that will mean hundreds of hours spent to rename everything back to normal. The data is very important, so if I must do that, I will. Then too, I will have to do it in segments, because no other partition (on the other HDD) is big enough for this data. But I can do part of it, and then dump that saved data to an external drive. It's amazing how quickly one or two bad clusters can totally screw up a whole drive or partition. I'd think that scandisk would have enough sense to mark these bad clustera as BAD, and leave everything else intact. I guess scandisk is not a very useful utility. The Scandisk.log file shows this: (Copied from Scandisk.log) Drive G_120 (G contained the following errors: Error reading your drive. ScanDisk may have corrected this error when it performed a surface scan. However, other errors may remain on your drive. Resolution: Retry the read Error reading your drive.

That computer is sort of built into a shelf and will require a lot of work to access, and if it only had SATA cable plugs, I will do all of that for nothing. I will do what is needed, but I might first go to my storage shed and dig out another unused computer. I know there is an old Dell in there that has XP and works, but it's a very slow computer, which is why I dont use it. But for this, it may be what I need. The DiskCheckup, from PassMark did give me a 404 error, but maybe it was down, or maybe my dialup is just too slow, or my Firefox 3.x cant talk to that site.
