Since all directories pretty much are laid out like: Directory Listing for File0001 points to first HD sector #, with pointer to second sector, which points to second HD sector # and has a pointer to the their sector .it is merely a matter of locating the first sector of your ZIP (or any other file you want to recover), locating the second sector, and so forth, then making sure the directory is properly updated with this information. Yes, you can spend days working on this recovering multi-MB files by hand, but it works fine. The solution was much simpler than that. Win2k has an utility called diskprobe. It allows you directly manipulate sectors. In fact in my case information in first EBR about the next extended partition was overwritten. It was matter of minutes to calculate the right data, write it and all the chain of extended partitions was recovered. However I spent the whole week-end learning about partitions in order to do this. BTW recover boot sector in NTFS is even easier. Actually I made floppy backup of all partitions tables as well as boot sectors. Now I am looking for two DOS utilities from NT4 resource kit: disksave and diskprobe. As for a program that writes 1's to disk, I wouldn't know. I'd just write a program myself. I am doctor not programmer! Maybe www.softseek.com or www.deja.com/usenet has some clues. No 1 From time to time I hear a rather loud click inside and Windeows freezes in that moment. This problem was present from the first time I installed the drive. What that could be? Does Windows crash or do anything bad? No it just freezes for a fraction of second. It's either the HD head moving about, or HD failure. Both IBM and Toshiba have low-level diagnostics programs you can run on the HD to make sure nothing bad is happening, just in case. This is certainly HD head hitting something. But I have never heard that kind of sound on other HD IBM or not. 2 Some time ago I read from your page about SIIG PCMCIA fan. Have you seen Win2k drivers for it? No idea. But one person who did try it recommended against it. It is such a tight fit that it damaged the MB/circuitry around the area and caused problems for that one person. however,that was merely an example of stupidity. If the card, if out of spec sizewise, was too hard to squeeze in, then why did that person proceed? I'm sure another PCMCIA fan card, if the proper size, would fit just fine and not cause problems. The name of "one person" is Nicolas Rubinstein. As I remember he is no longer on the list. He is otherwise smart guy and gave us many useful tips about Win2k and overclocking. By the way I remind you that he fixed his motherboard with a drop of glue. Remember, for all electronic equipment, it shouldn't need much force to put together. If it does, something is most likely wrong and you shouldn't force it in -- or else you'll risk damage. I must admit that card in question fits rather tight and if your motherboard is weak it can be damaged. But in my opinion his and mine problem is that we tend to forget that most so called IT professionals are just incompetent when are not trying to cheat you. It just hard to imagine that you paid $$ for a potentially dangerous misconceived card. Finally, David about previous suggestion about FAT. From all that I had to read about FAT/NTFS comparative stability I am happy to stay with NTFS. Most if not all recovery utilities just take the address from MFT of the first sector of file to recover and then recover the next sectors corresponding to file size. Thus, unless you defragmented partition minutes before failure your chances to recover are nil. Theese are just my 2c, Alexandre ** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ ---UNSUBSCRIBE--- mailto:[EMAIL PROTECTED]?subject=cmd:unsubscribe UNSUBSCRIBE DIGEST-- Use above but add DIGEST to the subject line... **

Re: 20GB experience + a few questions
Date: Sun, 22 Oct 2000 11:55:00 -0700 (PDT) From: David Chien [EMAIL PROTECTED] Subject: Re: 20GB experience + a few questions How can I find where Libretto hibernates before I loose any data??? One easy way is to get a program that'll write a series of 1's to the HD from just after oh, let's say, the first 2GB of HD to the end of the HD. You then hibernate, then run a HD hex editor over the entire space looking for anything other than pure 1's. Then, simply create a hibernation space that size and a couple MB bigger just in case. 2 Another weird problem happened to me which may explain my first problem. I was urged to get some data from a friend's desktop so I hibernated Win2k, went from hibernation. The files were not there! Actually I suppose that Win2k keeps all filetables in memory and on some occasions may restore them to drive after standby/hibernation. Can anybody confirm this? No idea here. But I'd start with shutting down the entire OS first before I'd pull any HD. Not a very bright idea to pull a hibernated HD unless you'd want a messed up HD. 3 I am going to use System Commander to switch from Win2k to Win98. Are there any hidden problem to ghost in this particular case? Ghost should be able to backup the entire partition w/o any problems. It doesn't care because system commander works on the MBR, outside of the primary partition either OS resides in. 4 What is the better choice Ghost or Drive Image? I have one point for Drive Image: it can verify integrity of allocation tables of all drives before dumping partition. For myself, I still go with Ghost. It has never failed, does the job, and works over the parallel port just in case I have no working floppy or CD-ROM drives in my PC (just as long as I can boot and get Ghost running that is..). However, I have used both to backup and restore HDs and they work just the same in the important aspects, but to me, it seems Ghost is more intuitive to me and works faster. Both have added the latest feature of going directly to CD-RW drives, but I haven't yet tested this feature. Did anyone managed to save partition directly to NTFS disk? DI docs say it I wouldn't think this to be likely, even with any 3rd party NTFS enabler. d =) = adorable toshiba libretto The latest news and information for the Toshiba Libretto owner. http://www.silverace.com/libretto/ __ Do You Yahoo!?
