recycle bin

It had 45 Gbytes in it. I remember 10 Mbyte hard drives. I confess that I remember 500 Kbyte hard drives. Actually, one 128 Kbyte drive.

I was a bit late getting my own computer - a used Amiga A500 of

1985 vintage. I managed quite well with a floppy drive only until I bought a hard disk adapter and a 630MB drive which was huge for its time.

Personally, I never put anything into the recycle bin. I just permanently delete them straightaway and have only mildly regretted it a few times. Any serious mistake in deletion could be reversed with any of a number of free recovery tools.

I once recovered data from a failing 160GB HDD for a government agency. The director came to my house to thank me and said that they would have happily paid 50 times the amount I charged them.

My first computer was a floppy only dos IBM portable with a small built in B&W monitor. I finally bought a 10meg hard drive, and paid over $100 for a USED drive. I made a bracket and it was on the outside of the computer since there was no space inside. I recall paying another $35 or so to have a local computer shop show me how to connect that drive and furnish an extension cable.

I dont have the recycle bin turned on either. And yea, a very few times I sort of regretted it, but I too will use a recovery tool, or get it from my backup drive. Not lonhg ago, I was always running my drives at their limit anyhow, so there was not room to spare. I finally dumped most of my storage on a portable drive.

Did you tell them they mis-read a couple of zeros after your figure...

:-) I'm kinda foolish that way. That particular recovery job involved more than a few mouse clicks. After recovering the most urgently needed files, I continued to work on it whenever I had some spare time. It stretched to about a week and I had to reconstruct a few files.

Nope.

Floppy, maybe. But no such hard drive.

...

My first hard drive was a 16 MB. An "MFM" drive, I think? I got it second-hand. It squeaked and squealed so bad I thought it was going to explode. But - it never did die on me.

I eventually upgraded it (retired) to something larger.

After I left MIT, I joined Memorex in Santa Clara. I worked on the Memorex versions of the IBM 2311, 2314, 3330 and 3340 hard disk drives. I designed the data recovery channel for the 3330 clone, then went on to design the entire read/write and data recovery channels for Pertec, Shugart, Diablo and Storage Tek hard drives.

I have 6 patents, one from MIT, one from Memorex, and the rest from my own company. Except for the one from MIT, all the rest are for hard disk drives.

So I was heavily involved in hard disk drives for a long time, but I don't recall any that had 500 kByte or 128 kByte.

The smallest I know of was the IBM 2315, which was a single 14 inch platter in a cartridge. It stored 1 MByte. As far as I recall, all the rest were 5 MB or higher.

Those were floppy disks. I think the first 8" floppy disks (SSSD) were

128k. Early 5.25" SSSD disks were as small as 80k.

Versions with DS, DD and/or more tracks had higher capacity, e.g. 1.2M for a DSDD 8" floppy.

My first HD was 5M (Rodime 205)

Of course. We were talking about HDDs and the effect of TRIM in SSDs sort of slipped my mind.

The 500K was a DEC fixed-head drive, on a RSTS time-share system with DECtapes. That was a luxury after paper tape.

I had a 64 kword (128 kbyte) fixed-head "swapping" drive on one system.

The original IBM 605 computer had 8.5 kilobytes of magnetic drum memory.

That was drum, not hard disk.

The DEC DF32 hard drive was 32K 13-bit words!

For the most part (the general masses)... the first hard drive incorporated into IBM brand PCs was the Tandon 10 MB 5.25" full height hard disc drive. But my exposure was limited to what I saw happenning, of course. So that could be off. Let the krw bandwagon retards chime in with their petty baby horseshit now.

Tandon also made the first 5,25 inch 'floppy' drives. They were even in the Atari game console system.

Noisier drives were always more reliable. SCSI server drives are another example. Why noisier is better, I don't know.

Until about 2000, all my upgrades were bigger by a factor of 10. Now I wish I could get a 10x upgrade.

I can remember paying a couple hundred for my first 100GB SSD about 6 years ago.

I paid $600 1991 dollars for my first 1GB SCSI full ht Seagate. That would be like $1100 today.

A couple months ago, I was getting ready to buy a 1 or 2 or 4 TB USB attached external hard drive. So I was at like just over a hundred dollars, then... The sales rep caught me before I bought and handed me an item which was on a special sales display up near the front of the store (Best Buy), and it was 8TB for $139.00. Same brand.

I keep checking before use to make sure I have space... I need to stop as it is going to be quite a while before I need to worry.

It is not TRIM that matters here.

Also note that "undelete" only works on some simpler and more limited filesystems - for many more advanced ones, it is impractical or impossible, especially if there are /any/ other write accesses to the filesystem between the deletion and the undeletion.
